What to Tune First

[jfpilla]

You stay in SD when dialing in the maf?? I thought youd dial it in with it reenabled, because in SD its disabled.

It's not really disabled. The functions that rely on the MAF are disabled. If you look at a SD log you will see the MAF still reports, but without any trim interference.

You can calibrate the MAF by way of LTFTs, but it's tedious and old school.
Joecar can probably give a more technical explanation.
I should have mentioned this part is CL.
