Default whats going on in these logs? - 09-28-2018, 09:17 AM

On WOT, see drop in boost overshoot as dme adjusts and throttle closes? Then can't really get to target. Any settings to try?


In this one, and I could feel it stock too, why do revs raise on this car after I lift throttle? This log look solid?

Looks all normal to me. Boost2 is manifold pressure. Throttle is used to control boost to target so if target changes throttle will help ramp boost down as needed. It's a control system.

As to why the ECU randomly changes it's target sometimes, better contact BMW for help on that, it's a mystery to us.

Thanks T! Yeah, car feels strong. I know how you feel but I'm really enjoying the MPPSK with a p1pe, and the 11test map6 is smooth! Who knows maybe that will change once we hit freezing temps.

I noticed FF raises from default on its own on test 11 map6, absolute 17 psi? Last I looked FF was at 149? Is cool? Here is a log.
