hey all

i know there are a couple who have looked into it, a 960 lemons car comes to mind...

does anyone have BIN and XDF files that i could use with an ostrich on M1.8

some searching brought up this, but im not sure how this gets translated into an XDF file

any help is very much appreciated

In the thread where I posted the list above I also uploaded a binary and xdf for 0261200528.
It does not contain map names though.

Generating a map list on M1.8 can be automated, but converting the data to xdf format is time-consuming and boring.
 
You are probably referring to festy.

The plugin is working. It can read the binary, and also read live data. Speed is quite slow though.
Reading 32kB binary should take about 40-minutes or so.
Live data was a couple of values pr. second if I remember correctly. Some improvements is possible by removing the ACK frame between readings, but KWP protocol at 4800bps is pretty slow.

The plugin has to be configured to work on Volvo M1.8. It does not contain any Volvo specific information.


I have made a few programs myself in the past for reading the binary and test some communication, but on M1.8 it would be better to use the 9-bit 187500bps mode for datalogging.
On a normal computer this is problematic though, so my plan is to use an Arduino Mega to handle the 9-bit stuff.
The second problem with M1.8 high speed communication is the switching between single-byte command/response and 10-byte frame live stream.

That's him

Will I still need the ostrich to tune or will the KKL cable let me do it?

I'm looking to play with the maps to suit boostus at some point, so as long as I have access to fuel and spark tables, the XDF dosn't need to be overly conplicated
 
Motronic 1.8 has an old fashioned UV Erasable Programmable Read Only Memory. 27C256 EPROM.
You need to replace the EPROM with an emulator like the Ostrich to make changes while running.

To make any changes at all you will have to open the box and replace the EPROM with an emulator or a chip with a modified program.
27SF512 will fit directly and can be erased without UV equipment, but some cheap eprom programmers have problems with this chip.
You will also have to double the program. When mounted in a Motronic 1.8 only the upper 32kB will be used.

The KKL cable will only let you read data from the ECU, not write.
It is possible to write to RAM using KWP protocol, but I am not sure if that can be helpful in anyway.
Theoretically it might be possible to overwrite adaption values to simulate map changes, but I'm not sure if it is practially possible.

Will have to wait till I'm home to look at the xdf

That's about the only sticking point now...

Once I have a BIN, are you or anyone else able to build an XDF for me? $?
 
I can probably make a list for you, but I do not have the patience to type all the numbers through the menu system of Tuner Pro.

If you note the map start address from the example XDF and look at the example binary in a hex editor you should have no problem in seeing the start of the main ignition and fuel maps in your own file.
Then you can just change the map address to fit your file, and delete all the other maps before you save the XDF with a new name.
