Need 80s Motronic xdf Help

[fred633]

I was told you guys are very good with 80's ECUs. I have a chip I ripped the bin from and have no clue how to read the bianary and make an xdf file for it. Can anybody help me?

Hello,

Have you looked at the Tunerpro site?

It will have to be made.

hows about some more details about the ECM itself?

what is it? what vehicle is it from?

does it have a part number?

do you have a high res picture of the circuit board so we can see what processor it uses etc?

how deeply do you want to tune it? would you be okay just guessing a few critical tables and experimenting?

it's a huge process to reverse engineer an ECM, a labour of love, especially when it's right from scratch,

if someone were to identify a similar ECM that has had research done on it, then one could infer some of the inner workings of YOUR ecm, such as table sizing and maybe make a few shortcuts using algorithmic or old fashioned graph searching, since code and table layout reuse is very common

I think it is a 0261200011 but it has a 24 pin eprom chip in it and most of those do not. I have bought 2 other 0261200011 ecu but those did not have removable chips.

It is a 24 pin eprom chip. It has no markings on it. It is 4kb in size.

I can't guess or use the old school trial and error.

Here is what I know from other XDF files online.

I appreciate your help as I am trying my best but just don’t know software and calibration.

that's some crazy ol' stuff! i don't know anything about motronic ECUs but post the bin and i'll poke at it a bit
