MAF on pressure side?

[audiman]

Well i did change ex. manifold at the same time. So maybe my experience was due to that. But the car was fine at WOT, just part throttle.

Thinking of doing this real soon.

Anyone had further experience in this??

does pressure not affect the readings? it is after all a hot wire sensor which is dependant on flow over the wire to cool it pressure means more air mass but less flow?

surely the ecu will see pig rich lambda and adjust accordingly?
Leaving the maf only useful at off boost conditions?

needs remap after this procedure

oops...kinda explains what I asked @ 91 s2

does the ECU measure WGFV duty cyle. As in, does it watch how many cycles it giving the wastegate for a particular RPM and if it steps outside of that part of the map then goes into some sort of safety cut?

seems pretty dangerous to have a turbo system that doesn't know when to quit spooling your turbo because it can't measure flow over boost and eventually over speeding the turbo?
