Posting your file would be a start.
No point to PM me at the moment, I am going on a small tuning trip for about week, so you will not get any answers...

bump, still been having fun with this, i tore apart a few audi bin's and more and can figure it out on all of those after a while, but mine seems to be quite a bit different, the part im stuck at is finding the right spot to inject a call for another routine

This file is nothing like the VAG files, the dwell strategies are completely different.

Have you found any dwell related tables at all yet?

anyone have that plugin from andy whittaker for IDA? maybe i could get a little bit more progress with that, seems you were right, the dwell is different in this bin, soft two stage rev limit works

even just somehow turning that into a basic hard limiter would be nice

The plug in will not help you, if you do not know what you are looking for.,

Ive disassembled your file and the dwell routine is nothing like that of VAG ME7, its no where near as complex.

Ive looked through Volvo A2L's and Damos files and everything is just different.

You need somewhere to start from, you cant open your file in IDA and expect it to be there right in front of you.

well thanks for taking the time to look at it, but yeah i know that its not going to be defined and be right there, that is why i have been comparing to files that are known, and after not getting any progress with my file, that's when i decided to post on here, but it looks like because of that fact i may look into something else Undecided like trying to remove the throttle plate closing portion of the rev limiter, it would be nice to just have it use the fuel cut and ignore touching the throttle actuator


edit : but then again, i still have to find the correct routine for that Undecided

The method used on the VAG files is possible, you just need to find one dwell map in your file and go from there. Ie use IDA to find the routine that uses that map and patch your own code into the routine.

hmm, seems i may have to use an older volvo as a test vehicle, i'm confused as to why my file is way different then 90% of the others i have seen.. maybe a different software engineer? i can find dwell in the newer and older me7 files, but mine is just not even remotely close

volvo sorry, seems older 2000's i can find pretty much anything, 2005-2006R's ive been able to find one dwell map im pretty sure

but mine a 2004s60R, looks almost completely different as far as placement goes, its like everything is just thrown around and totally out of order which makes it hard for me to find similar maps

update, found the right place to call a redirect for custom code, my only question is, will custom code written for vw/audi work, or does it all have to be ported over
