Thumbs up Fuel/Spark tuning for LH 2.4/EZK with TunerPro!

Update: 10/26/2012

So, I'm out of the LH game right now (and have been for a while). If you want a chip, please contact thelostartof. To everyone who bought a chip from me, thanks!

Update: 8/14/2011

www.jetronic.info IS BACK UP!!

If you are getting 'Page not found' errors it is because the page you are trying to view hasn't been created yet. Jetronic.info is a Wiki. I strongly encourage all of the chip-tuners and Ostrich users to register and share their experiences so we can build a comprehensive guide.

My hosting provider (123 Systems) deleted my VPS on accident and did not have a backup. Fortunately, I had written some scripts to do nightly backups so no data was lost!

E-mail registration is temporarily down while I reconfigure/lockdown sendmail...

----------------

Update: 8/03/2011

Because there are many folks working on LH besides myself, I have created a small, wiki-style site at:

www.jetronic.info


This site contains a file library that includes all of the factory BINs as well as the latest XDFs.

It is, naturally, a work in progress. Several folks have already contributed to the site, and when i have time and energy, i've been trying to gather all of the tidbits of LH-hacking related info (from turbobricks and other sites) and put it together in a meaningful way. ipdown has also added information relating to the more technical side of LH.

I welcome everyone to join and contribute!

----------

I have put together a package for tuning LH 2.4 9xx series ECUs and (chippable) EZKs. I am also actively developing a comprehensive XDF for the fuel ECU. New to this? Scroll down to "What is this?" heading below and start reading!

Last update: 4/19/2011

It's been nearly a month since I've updated this post. Blew up my car, working on a new job, etc. But! Every spare moment has been spent here:


And, after a bunch of coding, testing, and some frustrating issues with RS232 communication, I'm coming out of the lab, and now it's time to start datalogging folks:



What this requires:
1. Modified VAG-COM KKL Cable from eBay
2. Ostrich or chip burner
3. Laptop
4. Modified BIN and XDF: Download Here: beepee-logpack-v1.zip
5. Patience

Once you get it, open up your KKL cable, de-solder the OBD2 connector, and wire it as shown:


Or, alternately, you can go hard and do what Kenny did:



The datalog software is in ALPHA (i.e. it sucks), and we're still working on exactly what RAM locations are worth logging... but it's all very workable as-is!

Shameless plug: If you don't have a chip burner or ostrich, I will glady take your money and burn you a chip with datalogging enabled!

3/29/2011

LH 2.4 Doesn't suck as hard as it once did. Check it out:


ATTENTION: If you don't have an EPROM burner or blank chips, I will now burn a chip to your specs and mail it out to you for relatively cheap! See my thread for details.


Latest XDFs: Volvo 93x Fuel XDF v10 - Volvo 950 Fuel v10 - Volvo 984 Fuel XDF v3 (not being maintained) - Volvo EZK v208 XDF (not being maintained)

Currently I am focusing on the XDFs for 93x and 950 fuel software ONLY. Unless anyone has good reason, no other software will be considered by me.

Here's what's available in the version 10 XDF for 950:

Click image and say "ENHANCE" for larger view

Download the BINs here: BIN Kit: 93x and 984 Fuel, 204 EZK116 BIN, Tables, etc.

933 and 951 XDFs by mrjaybeeze: The latest will always be posted at at ECUProject.com's 'Volvo LH Systems' section. Register and git to downloadin'! 2/27/2011: ECUProject has updated their forum software and it is MUCH better! Check it out!

Build your own BIN from ASM source!
(If you don't know what this means, then don't do it. It won't make your car faster :-p)

This pack contains everything you need to build a 950 BIN from scratch. This is possible because of the well documented 8052 disassembly ipdown/Vlad has put together. If you know anything about assembly, you will understand how awesome this is. Thanks Vlad!

I have included modified ASM files with fuel maps and constants from stock B230FT software (the 950 s/w was originally for the B204FT). These should compile and run, but not necessarily well. These files are experimental!

I have also included ASM-formatted tables with the 012 and 016 AMM tables.

Also includes a fairly thorough 950 XDF with a bunch of untested stuff. Use at your own peril!

What is this? Why do I care?

This package should let you get started with tuning you factory fuel and spark computers. No more messing with resistors, zener diodes, and other nonsense in order to make the factory computer do what you like.

OMG! That's Great! What do I need?

I'm so glad you are asking all the right questions! You will need:

0. Get a bleeding wideband!
1. Vehicle with a LH2.4 fuel computer, part # ending in 9xx (not just 93x as stated)
2. Chippable EZK (not needed if only tuning fuel)
2. EEPROM Reader/burner
3. TunerPro RT v5 software (Free/donationware) Ensure you have version 5, 4.x won't work!
4. Moates.net Ostrich 2.0 EEPROM Emulator
5. XDFs and BINs (see above)
6. Programmable chips for storing your final tune

Crap! My ECU isn't a 93x-series? It's a [928, 946,962, etc] Will this work?

Yes! The 900 series ECUs have interchangable software. That's why I have included the BIN files; they should be compatible with nearly all 900 series ECUs. My XDF is only compatible with a select few BIN files, so I decided to work on BINs that have been proven to be very compatible (at least one chip is based on it).

Some Tbrickers have helped me put together a chart of compatible software/hardware, this is by no means complete:

Blank spots are where we have no information yet. If you have an ECU that has not been tested yet, let me know what software it will run and I will update accordingly.

Whoa there, what the heck are XDF and BIN files?

Note: BINs and ROMs are two terms for the same thing I use the two terms interchangeably in this article... because I just do.

Every LH-series ECU has an 27c256 compatible EEPROM chip. To grossly oversimplify, the chip is the 1970's version of a USB memory stick that only holds one file. That file contains all of the code and data that makes the ECU work. You could think of it as sheet music for an instrument, with the instrument being the entire fuel injection system.

Looking at raw BIN files won't get you very far unless you are an Uber-hacker and know 8051 assembly language, so we create XDF files that tell us where the important bits of the BIN file are. Smart people (like ipdown, blabla, and others I am sure) who understand 8051 machine code have helped by prying the file apart and identifying where the important bits are.

Generally BINs have two different types of information: code and data. The code is typically left alone in most chips, as it usually is fairly well written for the application. The data is what we are interested in.

When you start prying a BIN apart, you may find that at location X, a fuel table begins. TunerPro lets you create definitions (basically a slightly more complex bookmark) of sorts that indicates the location of anything you wish.

So let's say we've found the fuel table. We tell TunerPro that the table is 16x16, starts at offset 0x38c1, and is 8-bit (0-255). TunerPro uses this information and makes a nice table that is easy to adjust.

Once you have defined a few tables, flags, or constants, you can save the definitions in an XDF file. Other folks can use the XDF file to easily adjust the defined parameters in similar ROMs. So, a XDF file is a template file that makes it simpler to modify ECU ROMs/BIN files.

The downside is that you can have extremely similar ROMs with data in different locations. For example, the software on most of the 9xx series LH 2.4 ECUs is interchangable, but the XDFs are not. For example, an XDF for a 962 won't work for 984.

Once you play with it for a bit, it will start to make more sense.

TL;DR: XDF files tell TunerPro where parameters are stored in memory, making changes easy.

How does all this work?

Install TunerPro and load the provided XDF, then load one of the provided BIN files. At this point you should be able to double click any of the parameters and start changing bits:



I have tried to include appropriate information in each of the XDF parameters to get everyone started.

Ok, I think I understand this stuff, now what?

There are two methodologies for tuning LH 2.4. The cheapest way is to edit files using TunerPro, burn them to chips, and then test them out in your vehicle. Rinse, repeat.

The preferred way, however, is to use the Ostrich to do "real-time emulation". In short, you plug the Ostrich into the ECU in place of the chip, and make changes with the engine running!

But really, the best part is address tracing. With the Moates Ostrich, you can see what parts of the maps are being accessed by the ECU in real time. This is ideal for driver/co-driver tuning with the help of a wideband.

Where's the ignition stuff? My car doesn't ping and knock enough already.

The LH-Jetronic system only controls fuel delivery. If you have a chippable EZK you can use the same process to tune spark by installing the Ostrich in it's EEPROM socket. I have updated the ZIP file to include EZK stuff as well for those too lazy to hunt it down on their own

I have a 5xx series ECU and feel left out *sob*

The 5xx series are just as easily modified as the 9xx! Go look on the TunerPro site for an XDF. I'd still recommend getting a 9xx series however. The processor speed is faster, they can control E-fans, and just seem generally more reliable (I have a small pile of dead 56x ECUs ). Also, if everyone works on the same ECU version, we can more easily share our work! Go grab a 9xx unit from your local boneyard; they are literally plug-n-play! (well, electrically they are. Don't grab a NA unit and plug it into your turbo car until you have updated the programming!)

How did you figure out all this stuff?

I didn't. There are already XDFs floating around, and lots of information was gathered from the fine folks in the Volvo LH system area of ECUProject.com's forums. I believe the expression is "standing on the shoulders of giants".

What about chips?

While these tools will enable you to develop your own tune, this is no replacement for the effort and testing that has been put into professional tunes made available commercially. I bought chips even after I had some of this capability because personally I couldn't tune a 4-string banjo let alone a 4-cylinder turbo. And it was 100% worth it!

So why bother?

Why not? I'm positive someone else can improve on the work that has been done already. Perhaps not tune-wise but feature-wise. For example, changing to E85 will be much easier if you can adjust the fuel tables.

Help! I blew it up!

I told you to get a wideband you cheapskate. Tweaking LH2.4 is even more dangerous than playing with Megasquirt because there is no public documentation on exactly how LH2.4 works. So be careful!

heh, stock is crap yo, y don't u just get megasquirt?

x 1,000

The advantages of modifying the factory system are clear. Go look at the Honda/DSM/Ford guys online. That said, I know MS is capable of more, and better documented. If you need water injection or nitrous or launch control then a standalone is the way to go. BUT, lots of power has been made with LH, and Megasquirt may be overkill for those not looking to go beyond a certain level of complexity.

Also, I'm tired of the infamous and extraordinarily helpful one-sentence reply, "time for MS". So there

I found something! I found something!

Great! Update the XDF and re-post it!

That being said, good luck to everyone and thanks again to all the folks at ECUProject for sharing the information!

Installing the Moates Ostrich 2.0 EEPROM Emulator in my '90 740

IMPORTANT: You really should load a BIN into the Ostrich before installation. Follow my "Emulating with the Ostrich" tutorial up to Step 5 and you should be good. The Ostrich doesn't need to be installed to program it.

Note: if images don't load, try again. Dropbox sucks.

So you took the plunge and are ready to start tweaking your ECU. Great! Here's a step-by-step of getting the Ostrich installed.

You will need:
Electrical tape
Small flathead screwdriver or needle-nose pilers
Phillips head screwdriver for removing kick panel
Socket for removing ECU retaining bolt
Ostrich Emulator (hurrr)
Steady hands

Remove the kick panel from the right hand side of the passenger's footwell. You should see the ECU. Remove the retaining bolt from the ECU.

Pull the ECU out of the slot BEFORE attempting to disconnect it from the harness. I've done it a few times and it's way easier without the ECU in it's cradle. Disconnect the harness.

Flip over the unit and there are ten metal flaps holding the lid on. Use your flathead screwdriver or needle-nose pliers to bend them out of the way. Find a relatively static free location to work and open the lid!

NOTE: I didn't write 'FUEL CONTROL' on the ECU, the PO did. Ugh.

Alt image: http://i.imgur.com/c2dIC.jpg
I have already removed the factory EEPROM in this picture; it is in the socket in the top left and usually has a white plastic retaining clip.

Using your flathead screwdriver, remove the EEPROM retaining clip. Then, gently start easing the EEPROM out of it's socket by slowly wiggling in the flathead screwdriver from either side, a little bit at a time. Be careful not to scratch the PCB. Once the EEPROM is out, put it somewhere for safekeeping. An old film canister or Rx bottle works fine for this. If you have some antistatic foam, press the EEPROM's pins into it to prevent them from being bent.

Time to install the Ostrich!

Alt image: http://i.imgur.com/MbNAZ.jpg
Note the orientation and insert the emulation header into the socket. It should press fit snugly. Ensure that all sides are inserted securely.


Alt image: http://i.imgur.com/KSjr6.jpg
Fold the cable back on the header; it will be exiting the ECU via the top


Alt image: http://i.imgur.com/EFtCM.jpg
Wrap some electrical tape around the cable where it contacts the metal edge of the case. This will prevent the case from pinching the cable.


Alt image: http://i.imgur.com/0WA43.jpg
Install the case. From the rear, bend the right-most tab on top all the way back to clear the cable.


Alt image: http://i.imgur.com/TusH4.jpg
Bend the highlighted tabs back into place to secure the ECU. We will leave the ones near the cable unsecured to prevent pinching the cable any more than necessary.


Alt image: http://i.imgur.com/SJihO.jpg
In the car, run the cable into, behind, then out of the ECU retaining bracket. Gently re-install the ECU while taking up slack on the cable.


Alt image: http://i.imgur.com/2ihJB.jpg
Take your pliers and slightly bend the retaining bracket outwards. Feed the cable back in, and attach the Ostrich. Fold the cable and press the Ostrich into place as shown. Vacuum your carpet! You're done!

Emulating with the Ostrich 2.0

So everything is plugged in, nice and neat. You've got your wideband installed, and a nice shiny gauge to go with it. Now we need to get the Ostrich loaded up with some firmware; it does not inculde any by default.

Step 1. Install the drivers
My Ostrich didn't come with a driver disk; they are available online.

Go here: http://www.moates.net/usb-driver-p-215.html

Note: The Ostrich is a FTDI chipset USB->serial device; you may have drivers already. I still recommend using the drivers available online.

Step 2. Plug it in!
Windows should do its thing and indicate that the hardware has installed successfully.

AT THIS POINT YOUR KEY SHOULD BE OUT OF THE INGITION. DON'T TURN YOUR KEY ON WHEN THE OSTRICH HAS NOT BEN PROGRAMMED YET, THE ECU COULD DAMAGE SOMETHING, FLOOD YOUR MOTOR, OVERHEAT A COMPONENT, POSSIBLY KILL YOUR NEIGHBOR'S CAT. DON'T DO IT. It probably won't do anything, but don't take the chance.

Step 3. Launch TunerPro RT
Open TunerPro RT. If everything has gone well up to this point, you should hear a two-tone "happy" beep, and TunerPro will acknowledge the Ostrich. The status bar at the bottom of the TunerPro window should say something to the effect of "Connected: Ostrich II USB". You are now officially cooking with gas. Let's load a bin and start the car.

Step 4. Load BIN and XDF
From the XDF menu, click Select xdf. Next navigate to the folder where you extracted the zip package posted above (you did download it, didn't you?). Because our Ostrich is installed in the LH2.4 fuel computer, we need to load the XDF labeled Volvo_LH24_93x-beepee-v4.xdf'

When the XDF is loaded, you should have a few items in the Parameter Tree in the left hand side of the TunerPro Window: Scalars, Flags, and Tables. Scalars are single-location memory values; a good example is the RPM limit. Flags are simple parameters that can be toggled on/off. Tables are where the interesting stuff is. We'll get to this more later

Next, load a BIN file. From the File menu, select Open Bin. Again, navigate to the folder where you extracted the zip. At this point, select the appropriate BIN file for your configuration: 0280-000-935_1010205_NA_LH244 for NA motors, 0280-000-935_1010307_Turbo_LH244 for Turbo. If you are a +T, you want the turbo file. The third BIN is for a B200FT, if you have that, use that BIN. Select the file and click OK.

Step 5. Sanity Check
Let's make sure the BIN we've loaded and the XDF we have are compatible. Under the Tables section of the Parameter Tree, select "Main Fuel map" (double click to open). It should look similar to this (NA will be a little different):



If the XDF and BIN are matched correctly, your fuel map should have a nice smooth gradient. If it is all one value or has odd stripes running through it, something went wrong. Slap yourself and go back to Step 4!

Step 6. Program Ostrich
We've got our BIN, we've got our XDF, and we are ready to go. In the middle of the TunerPro toolbar, there is a series of three arrows. From left to right, they are Upload, Download to TunerPro, Download to File. We want to upload. After you click the upload button, you should see a status bar at the bottom of the window, it usually only takes a few seconds. When the upload is done, Select Tools > Emulation > Start Emulating .

Step 7. Start the car!
At this point, we are plugged in, programmed, and itching to start the car. The bottom left corner of the TunerPro window should have a GREEN inicator (Emulating). Now we are ready.

Turn the key to run (not start) and listen for the fuel pump. You should hear it run for a few seconds, then shut off. If it does not run, you need to check your connection between the Ostrich and the ECU.

If the fuel pump primes successfully, start the car! Congratulations!

What's next?

Well, first we can try something simple. Let's change the revlimit of the fuel computer. Select the Scalars > RPM Limit from the parameter tree (double click). You should have a value of 39. If you open the RPM Calc sheet included in the zip package, you can convert LH2.4 8-bit values to RPM. Let's set it to 90 (about 2100 RPM). Once you have entered 90, click Save. You should hear some more "happy beeps" which mean your changes have been sent to the Ostrich. Step on the gas and see if it worked! For other RPM limit values, hold the mouse over the RPM Limit parameter and read the tooltip, I have included some common ones there. Don't forget to change it back when you are done!

Ok, that's neat, get to the cool stuff already!

Address tracing is where it's at. With the car running, open the Main fuel map. Click the large "A" button in the toolbar for the fuel map. You should see a cell highlight. Rev the engine a few times and watch it move. The highlight is the active fuel cell being used by the computer! Increase for more fuel, decrease for less.

The table axis looks all funny. What is going on?

Because LH2.4 is ancient (in the computer world at least) it stores all (well, most) of it's data in 8-bit values. This means that no number can be less than zero, and greater than 255. When you start counting RPM, this obviously becomes a problem. I have more or less figured out a formula to calculate RPM and put the RPM table for that reason. TunerPro has built in facilities to do unit conversion, but it doesn't like my formula for some reason. Grr.

A table axis in LH 2.4 is not the most straightforward thing in the world. The axis starts with the minimum value, and each column after contains a value that is subtracted to establish that column's value. Here's a simple example:

HTML Code:
Human-readable axis:    100  105  110  125  140  150  155  160  180  195  200
The same axis in LH2.4:   5    5   15   15   10    5    5   20   15    5  200
Basically, each value is subtracted from the result of the previous column. What a pain, huh?

Other notes:

- Be sure to disable Lambda when tuning with a wideband, LH2.4 likes nothing more in the entire world then an afr of 14.7 and will attempt to stay there religiously!
- If you suddenly get a Check Engine light, it's probably because the checksum is incorrect. When ipdown's program is done, it will auto-correct the checksum on the fly. It shouldn't hurt anything.
- You can remove the usb cable from the Ostrich and still operate the car just like normal. It retains it's memory even when the car is off.

And, finally, just in case it isn't clear:

ipdown, blabla, sbabbs, frpe82, mrjaybeeze and many others who I am forgetting from the ECUProject forums are who made this possible!
(if I left you out, sorry let me know!!)

Thanks for all of your hard work!

Pictures will be posted... eventually. Good luck everyone!

I love you again Like I said, Cody and I were just saying how a simple How-to would be sick, but people are dicks who posses the knowledge. Much appreciated man.


Also, the party began HERE. Post #18 beepee steps up. good info after that.

Oh snap. (I hate how I say that. I used to hate that saying, still do, but it seems to fitting...)

For those who don't have a 93x computer, you don't need to have one to tune LH2.4, but you will need one to use this XDF file, etc..

For those who don't have a 93x computer, you don't need to have one to tune LH2.4, but you will need one to use this XDF file, etc..
Actually, the bins in the zip file should work on any 9xx series ECU. My bad! Fixed.

The Ostrich 2.0 emulator plugs into the normal chip socket. Remove your chip as if you are going to install a modified chip from Hi-Tuning or TLAO, and plug in the wiring from the Ostrich instead.

Ok, going to bed, keep asking questions and I will try and update the OP tomorrow afternoon; perhaps take some pictures when I get back home (I'm in Baltimore currently)...


And klr142 I'm glad I am not the only one who can answer questions

No problem. If you had done this two months ago, I wouldn't be much help!

Also, the party began HERE. Post #18 beepee steps up. good info after that.
Yeah I mean after a few hundred bucks I think I could have a very serious tune going on. My father (race car tuner) and I, have been discussing the fact that these cars have way more in them than the computers let on. I'd rather tune stock computers over MS because, well I got into Volvos to be DIFFERENT, and I'd love to provide chips that were different from the other guys, not saying I don't dig their stuff, I'm just saying I'd love to expand the Volvo performance market.

Now I just need the fun stuff; More to come from me in the summer time!

For an eprom burner, i got a TOP853 (thanks Blabla/Ruben!) It has a USB port so it will work with a modern laptop, most (cheap) Willem programmers that i found have a parallel port. The software of the TOP853 isnt great but it works. You should be able to get one for ~35$ shipped. Even without ostrich, you can have some fun with the eprom burner (cheap start until you want more).

You can use 27SF512 chips too (those are EEPROMS, so no UV-needed for erasing). I didnt get those to work yet though. Those have twice the memory size too so you can use those to have switchable mapping.

One thing i really like is that i managed to get my car to start a lot better. The E85 needs more fuel during cranking. then a few seconds after startup i reduced the amount of fuel injected. runs much more stable/elegant now when cold. should waste a bit less fuel too this way.

I cannot stress how much help i have had from the ecuproject people and people here (Ipdown, Blabla, JR-66, Jens and others). read up on ecuproject, lots of valuable info there.

If you download many of the bins posted on ecuproject and open those with winOLS you can see what is different.

Another cool program that Ipdown made: Injector scaling tool for LH24. Now 630 cc injectors, 016 AMM and E85 and the engine runs perfect from first startup, no tank of fuel needed to get it to learn things.

This program works really well, running E85 now without the resistor in the AMM line and engine revs much better off idle and pulls better too!


We (JW240 and I) made a little example video when you try to change the idle rpm with ipdown's program.

Maybe I do need to try that injector scaling thing... I'm only using the 16V injectors in place of the 8V(N/A) ones, but it does make a difference.

And, I didn't know you could tune on the fly immediately like that! Are you able to mess with the mapping as well? That's sweet that you can immediately tweak stuff like that. I'm ordering one now.

Another thing I think I remember that may be of interest, is that you can use any ignition chip in any chippable EZK. You don't have to have the bin specific to a certain EZK module. Is that correct? Pretty sure it is. So, one could take that -208 bin and use it in their -146 computer if that's what they have. Make sure you are using a N/A bin for an N/A car and Turbo bin for a Turbo car though, you may not be satisfied with the results...

You can use 27SF512 chips too (those are EEPROMS, so no UV-needed for erasing). I didnt get those to work yet though. Those have twice the memory size too so you can use those to have switchable mapping.

Start programming half way into the chip at 8000 and 512 chips will work....

I tried 'chip start' at 0x8000 but no result. Looking at the software (topwin6) later i realised that maybe 'buffer start' at 0x8000 could have worked? Strange thing was that with pin 15 not plugged in but bent away it still didnt work. Also when starting at the normal value (buffer and chip start at 0000) the car didnt want to start with it. the chip didnt give any trouble when writing/reading.

You can change whilst the engine is running yeah, you can also change cell values in fuel mapping (with the engine running). Works really nice with a co-driver that operates the notebook

I like this new willem programmer, USB and does 40 pin chips so I can reprogram lh2.2 ezk chips as they are 40 pin.
