Default for people with hptuners and SD tuning.

i cant believe i just now thought to try it, but whenever you disable maf you trans automatically goes to max pressure overide and makes in car street tuning very un-easy. i kept looking through everything till i had a duh moment, so hopefully future members can see this and save the trouble.

I never noticed that... but I have a manual transmission!

I tuned both MAF and SD on my car, but its difficult to get the SD as close as you can get the MAF due to the build in error on the Bluecat software (and the impossibility of hitting every cell in the table). It's worlds better than doing nothing, but you can't dial it in to be +/- 1% like you can the MAF.

Good info to share!

I'm running the 2 bar MAP-Speed Density OS, and I didn't have any issues with trans pressure.

You wouldn't on the custom os but on factory you would have that issue
