Hi Twiki.
Unfortunately, nothing to do with understanding ECU code or tuning it is easy for the newbie, or indeed for the experienced. The nearest thing you're going to get to plain English is plain Deutsch!
I've said this elsewhere on this forum, but it's probably worth reiterating here: some months ago, I bought a collection of Audi ECU definition files from a tuner when researching a technical bulletin/FAQ for another forum + my own interest on ECU remapping for the Audi TT engine variants. I have looked through them and posted up the ones which appeared to be authentic and with all
konstanten,
kennlinien &
kennfelder fully-defined as per the 335 'modules' as I call them in the ME7.5
funktionsrahmen in the WinOLS .ols file format. This means that anyone with an interest can download the test version of WinOLS and browse all the parameters in real-world (i.e. scaled and offset) form. In that respect, they differ from the basic binary format files (labeled .bin or .ori) which are just collections of hex code that, otherwise, someone would have to interpret and define manually, usually by comparison with a similar, known file.
The fully-defined DAMOS, A2L or .ols files are so much larger because they contain all that extra information over and above the plain binary/hex code.
I know nothing more about the files because I've never worked with them or tried to tune them and flash back to an ECU. The only files I have any experience with are the TT 1.8T 225 PS BAM and 240 PS BFV variants. The one I posted up which was commented by gremlin to not be an A4 150 PS 1.8T engine variant I can only offer with cautions and caveats attached. I removed it because of the uncertainty, but you guys wanted it all the same, so there you go. I can't help any further with that one.
I don't even know how you would save the .ols file as a plain binary, but it sounds like something WinOLS can do. If it can't, have a look around all the internet forums dedicated to amateur ECU tuning for the binary file you're after. Chances are it will be out there somewhere. Moderators generally don't tend to like people telling their members to go to another forum, so I won't do that!
We seem to have plenty of good professional tuners distributed around the U.K. so for a few hundred pounds, you can get a good remap and it isn't worth trying it yourself except for an academic exercise or personal challenge. But I guess that with the size and remoteness of North America and Canada, means that you might be a long way away from a good Bosch ECU remapper.
