Why don't we zero every f'ing table, put the car on a environement controlled dyno and spend weeks, or months recalibrating the whole ecu from scratch?
Get real.
Ignorance is bliss. Calibrating ME7/MED9 PID from scratch with adaptations and corrections active is a sure way to disaster.
Zero all offsets and then re-populate based on the pre-populated maps, but choosing your current conditions at zero point. You are not throwing away any data, just making life a lot easier.
ldimxak_w should be zero all the time during calibration regardless and unless you really know what you are doing and know how to adjust it and it's adaptation points, should never be enabled at all.
I am done on this subject - if you do not understand what I am saying, then so be it.
I restored KFLDRQ0 to the same level as it was previously, and increased KFLDRQ2 in the region where the turbo starts to spool and reaches the maximum spool.
It dulled the spike in ldtv significantly, however the spike is still there. I logged ldptv, ldrdtv and lditv this time instead of the raw ldrk? values.
To be honest, trying to understand PID even remotely is probably the hardest thing I´ve ever done. I have no idea what I am doing, obviously
I would assume ldrdtv isn´t suppose to look like that...
I'd request a little more boost earlier on. That will help with your D spikes... but that is a hack.
You can reduce D at high Delta P, and increase D at low Delta P. That should help with unneccessary high D at large Delta P that you are having initially and lower the overshoot towards the end with lower Delta P. (P as in pressure).
