Maf only , STFT in open loop ?

[Maxspeed96ct]

A friend of mine just picked up a new TA, built 4l60e, cam and related bolt ons.

I set up the lockup for him and made some shift adjustments, next I' right now , next ill be doing a full re-tune once he gets a few things done.


As I look through the tune, few things are different then what I have done in the past.

1st - I see the car is set to run all maf 200 rpm and up, I plan on putting it back to a mix of VE and MAF. Unless someone wants to direct me otherwise.


2nd - STFT in open loop is enabled, i' ve never seen this done before, is it because of the tune being maf only? Anyone want to school me ?


Thanks

Bump , any one has a guess on why someone would want Stft enabled during open loop ?

It's enabled from GM on some calibrations.

[Maxspeed96ct]

In that case should I leave it enabled ?

You can disable it if you want to...I don't see a negative to disabling it.
