Good questions.

I have a C7 with D.I. also and downloaded DSLogRedux as well.
After using the software (which is really a nice feature), I wanted to adjust my LTFTs which are -9%.
Come to find out from the forum leaders that we can't.

So, do we need to worry about LTFT with D.I.?
Maybe we could ...

Mike:

First off, the Diablo Trinity is a quite an empowerment tool! Not just horsepower. Thanks for making it.

I have run probably ten logs on my C7 and think I see where I fill up affects both my knock and possibly my idle.
A little touch of TORCO Accelerator seems to make quite a difference ...

Trinity Users:

I have a stock 2014 Corvette Z51 7 speed. Just started using Trinity to explore a noticeable rough idle. The idle is rough for both stock and Diablo 91 tune.

I see STFT varying at idle (+/- 20 rpm) as well O2 sensor voltages. My LTFT is around -9% on both banks.
I was thinking it ...
