These types of comments are totally inappropriate, condescending and disrespectful speculation with zero basis for your conclusion. How could anyone know what another person is capable of be it coding or anything else?
The point of my comment was there are more than one means to achieve a goal with ME7 and people are free to follow the road less traveled including the OP who desires a viable solution for his specific needs.
The only thing you have posted in this thread is mindless technobabble, bullshit and asskissing. You are not contributing in the least to it.
Feel free to be offended and call me rude. I don't care.
Really wasting my time on here. The guys that have the most knowledge, and can answer a question so quickly, rather choose to tell a person how they wasting their time, and try prove others wrong. From the posts ive read back in 2012 etc, everyone tried to help. Now its a matter of arguing, and then paying for help.
As I said before. R32 turbo is the most difficult project you can undertake on the ME7 ecu.
There are very few people in the world who can do it right and these people do this stuff for a living.
Why would I or anyone else for that matter work for free?
That said - this thread has deteriorated far beyond the original question.
Your original question is fueling under boost. This is the same as ANY other ME7 ECU. This is detailed in the FR and also on nyet's wiki.
Fueling and timing is NOT handled in any special way by a NA ME7 compared to a turbo ME7.
So really, your question should be "how to tune fueling on ME7". Because the fact that it is a R32 ecu and that it is boosted makes zero difference on the fueling side of things.
With the boosted R32 to do the tuning right is:
1. Locate the lambda post turbo and copy the fuel trims from bank 1 to bank 2 in the code.
2. Add some code to emulate the function of KFVPDKSE. Can be simply if pssol_w > KL(nmot_w) go WOT.
3. Add a pre-throttle sensor and multiply the incoming air by the pressure difference over the throttle plate. Alternatively model it, by specifying a factor based on KF(nmot_w, ps_w) calibrated empirically.
4. Add code for boost control, so ECU has some means of targeting and maintaining pssol_w apart from closing the throttle. I have controlled pressure off of the MAF (ps_w) so it works like M3.8.3/M5.9.2 and also by replacing the MAF by a manifold pressure sensor.
5. If you need more than 1.5 bar boost, then the 5120 mod.
But none of these things have anything to do with fueling per se. If you are not running more than 1.5 bar and you have pre-turbo lambdas then the rest is load/throttle control only.
The reason your fueling is bad is because:
1) Request - are you requesting correct lambda? This is as simple as changing LAMFA and rescaling KFLBTS to accomodate the higher load points + adjust the BTS triggers a little. But for lower boost you can just target 0.8 with LAMFA and it'll get you 95% of the way there.
2) Actual:
* Hardware - is your fuel pressure alright? Do you have a returnable fuel system? Do you have a vacuum controlled FPR? Does your pump provide enough pressure?
* Software - is your MAF scaled right? Are your injectors scaled right? What about correction maps such as FKKVS? KFLF? KFKHFM?
Remember - you are entitled to nothing. No one has to answer any of your questions. If you can't figure stuff out from the FR, then forget doing this, fit a standalone ecu and save yourself all the hassle. If you just want to get it done, then I am sure in every corner of a world there is at least one specialist who can get this done. Dump the car there, pay money, pick it up when it's done. You have been so far asking about really basic things. Things that are very easy to figure out from looking at the fr for lamfa_w, lambts_w and lamsbg_w paths.
Also this thread is lacking proper logs. Without correct logging you can forget doing this.
