I should probably add a caveat.... the "modified" bin files I uploaded to github were made by a tunerpro newbie (me). So something could be off.
The stock bins are of course, stock.

Hi
I have been a contribitor to the M44 tuners rejoice of volvospeed under the nickname "Piet".
So I thought: maybe I can offer some help here

After a quick look it seems to me that the injector constant is at 0xEE2 instead of 0xEE4

Cool! I'll make the change in the XDF to try again. Thank you for your help, I've seen your name in that thread, although I haven't been able to read all 475+ pages, lol.

No, my mistake.
Took a closer look and the IC is at 0xEE4
Sorry for the confusion.

Not a problem at all. I'm just happy to see I might have gotten it right, haha. I wish I had a V90/S90/960 on M4.4 to test this stuff out. I tend to take on projects I have no way of validating.

Any way to dump the whole chip without desoldering the chip? Don't want to flash it before i get the original bin from it.

I based it on something called OmegaDiag, and changed it to work on Volvo.
Select "old" protocol and 27C512 for 64kB on M4.4 on the options page.
"Dump EPROM" on main page after Connect. Sometimes a few tries is needed.
Rkam posted this on page 2, post #45. It wouldn't be a full 128kb read, but if it returns the hardware/software # so you could easily find the same file online to flash back.

I have done this last year when i started to 2 of my ecus both 0261204002.
When i compare the both files i find differences in the file, not much but some maybe "maps" are different.

But im still looking for a way to dump the whole 128kb without desoldering the chip.

I'm pretty sure it could be read via BDM, but without the proper equipment, and instructions on which PCB pins to probe, it could be a difficult process :(.

The C517A CPU does not have a standard Background Debug Mode.
http://www.keil.com/dd/docs/datashts...n/c517a_um.pdf
In M4.4 the CPU comes with a protected internal program that can be used to erase and flash the external flash memory.
Running internal or external ROM/Flash is selected by the EA pin on the CPU.

It is possible to read the whole chip without soldering, but it requires opening of the box, possibly unsafe voltages and short circuiting address lines.
I can not recommend doing this for backup. You should find an identical ECU with the same hardware (0261...), software(1.037... or similar) and part number.

It might be safer to try to freeze the CPU, and connect the flash to an external reader that is strong enough to pull the required pins.
Maybe keep the CPU in RESET, or short circuit the XTAL pins.

For fun I googled that part number and found this

http://shop.fekzen.se/en/volvo/283-v...hip-90-98.html

Info.. (Works out at <$300)

Turbochip is a tuning chip with retarded ignition so that the engine will support overboost. Due to bigger injectors is needed to give enough fuel, also fuelmaps is remapped to fit the injectors. With the Turbochip you will be able to boost more and run more safe cause the margins is higher.
We recommend you to use injectors which has a maximum size of 630cc and also use a wideband lambda sensor to make sure you have enough fuel to get a good mixture.
The early version with M1.8 has a socket already, but the M4.4 from 96 require soldering when installing the chip. Contact us for more information.
Ex ECU nr: 0261203453 , 0261200362 , 0261200528 , 0261203854 , 0261204002 , 0261204643
Notice - You should use an adjustable fuel pressure regulator to be able to make some smaller finetuning by your self, while testdriving.


I haven't had a chance to look at mine still. Just got done swapping out a power steering pressure hose which was a bit of a pain in the ass.

Hi, i have some files that i would like to share where can i upload them?

The files is from 0261204002 box, one is the 64kb bootmode read and the other is the full chip read, when i compare them they have many differences at the same places but both files are from the same box ��

You can upload them here and I'll get them up on github... https://uploads.kartpulse.com/ownclo...cvJZ9bW7RUxV7Z

No progress on mine yet. I need to get the motor back together in the XC90, then do some maintenance on the e39 before I touch the 960 for anything "fun".
I did get the ECU\ECM pulled out to check the P/N though so I can at least grab a spare ECU and try some things as I have time.

Yes i will upload the files next time im on the computer.
Did get the full correct read now.

Anyone know where i can get a dip-32 to plcc-32 adapter so i can get my ostrich connected?

That E32-0035 would work but its almost 100usd with shipping to Finland..

for a heads up there are several m4.4 computers out there and the software are not compatible

for instance 0261203xxx is not compatible with 0261204xxx as as there is hardware differences same goes with the Immo / non Immo units ..

also 204 firmwares differ greatly and i have information on what Changes are on what units

avalible is also removal of all Comfort / ignition retard when driving sporty and all sorts of stuff avalible

here a fairly recent dyno using b6284t and motronic 4.4 on dyno

The rev limits are correct, just soft and hard swapped. Atleast works on 0261204002

NICE! :D
Thank you for testing! That's a big help. I'm still debating trying to set my car up on M4.4 to make testing easier, but finding what I need is proving difficult :(.

Which XDF did you use? Did you ever find a way to upload the files? I'd love to take a peek at what you've got.

I could let you have my old t6 modified bin it's pretty outdated and rough in adjustments but it has all basic stuff removed that you want to remove like comfort settings rear lambda. and optimized for 337cc injectors

I'll let you know later


a heads up though there are versions of m4. 4 that's is not compatible in software or hardware there are a also one version that has bit offset and swapped fuel pump output primarily California spec

Cool, that would be much appreciated . Anything that could be used to learn more would be awesome.

Good to know about the different ECUs. I wonder why the cali-spec one is so different. I'm guessing then that some softwares won't work on some ECUs. Does it brick them or are they recoverable?

I will check what xdf i used, i did upload the files (atleast tried) can upload them again on the weekend 😀

And if moon_walk could share some stock bins it would be much appreciated ☺️

If you change the extension to something like .doc, you can attach them here.

Oh, that bin is from a 2.5L? That's even better! I took a look at it, and I'm amazed that the 2.5 and 3.0 files are pretty similar. Very cool, thank you for sharing!

Yes that is from a 2.5L manual. On the revlimits it seem that the Hard is off and Soft is back on. Now i need to test to disable the rear o2 sensor
