Hi Guys,
I'm working on finetuning my car after some months of building it up again after my first n54 e92 was damaged during an accident.
I have used the default Upped turbo maps for the Procede and running a Vishnu EU flexfuel flash.
My plan is to finetune map 1, then optimize map 4 with meth. I think there is still some potential out there.
As I do live 40 km's from an e85 tankstation I bought the Flexfuel kit, but Vishnu offcourse never provided a map for RB's and Flexfuel.
Eventuelly I would like to work on a flexfuel map for RB's and adding a fuelpump system for to provide sufficient fueling.
Specials: I run M4 plugs, I have a new LPFP sensor and new HPFP.
My PID P is set to .5, I have disabled the AFR tables. Further info can be found on my datazap upload.
I have two logs:
- One with OL Fueling set to 28 and start ignition on 75 (Log 9)
- One with OL Fueling set to 20 and start ignition on 70 (Log 12)
http://www.datazap.me/u/rismo/335-fb...log=0&data=1-5
I'm wondering to your opinion about these logs, I made the following observations myself:
- Seems to have some boost oscilation, but not sure what is acceptable
- My fueltrims raises in upper rpm range, but not sure why
- Sometimes when I break and push it again I feel that the car is having a bit harder time to get back to speed again, is this the famous timing flatline issue? I do not observe this when running the BMW factory map.
Timing and AFR seem to be quite fine.
For now I would like to optimize both timing, fuel and boost, and would like to set it up for trackracing, I believe best is to tune for optimal timing with supporting boost instead of maximizing boost with supportive timing as I want to keep temps low as possible.
I hope for some support and want to avoid tuner discussions when possible. I might head a different tune direction but for now I want to maximize my investments.
Thanks!
