Tuning speed density

Hi there

You explain how to fail maf, does this affect the IAT sensor attached to Maf? U also adjust DFCO if I bring this back to original setting will the maf fail not work anymore, while in SD

Hi Nashalan, sorry you'll need to point me to the specific video to give you a complete answer here. Failing the MAF doesn't ignore the IAT sensor, only the actual MAF input to force SD. For an SD calibration where the MAF is removed from the system entirely, a separate IAT sensor is required. I'm not sure on the specific changes that were made to DCFO but these shouldn't affect SD operation.
