WOT Pull Jumps to base map

[AutoErikBS]

Hi

I have a costummers Ford Mustang on the rolling road.

It keeps jumping to base timing under WOT, sometimes it jumps back to borderline and makes decent power, other times it stays in base timing.

I have tried to zero the iat, ECT lambda corrections map without any difference.

Check IMRC operation. Base means its reaching MBT values, with IMRC closed that would be the 12* like you are seeing not the 28-31* where it should be.

Hi

The car is equipped with a Ford Racing intake, cams, Throttle body & MAF. The OEM IMRC is removed.... The looks like this kit: https://www.americanmuscle.com/ford-racing-intake-manifold.html

Do you have any setup files or information on how to set it up, disabling IMRC doesn't help on the problem..........
