STFT = 0 at high rpm
I just started data logging not too long ago and researching tuning. I noticed that my STFT are always 0 when the engine is above certain RPM's. Does anyone know why this is the case? And do you mind looking at this log since it seems like I am dumping fuel out the pipe when idling, but it looks like I am occasionally rich.
Some extra info:
Car was tuned by reputable tuner
LS6 with intake and catless headers.
I don't have a wideband when data logging (should I get one?)
LTFT are disabled with tune
with harness.hpl
C5-3-3-24.hpt

Trims are not used when it goes open loop, which it does with heavy throttle/whenever PE kicks in. You have the "Fuel System #1 Status" PID logged, it tells you when it switches over.

Well I guess I have shown how dumb I am. Thanks for the info.
Also, how is the car scene in Meridian? I live in Starkville, and it is only college kids and squatted trucks up here.

Same. Straight pipes and big chrome tips. Loud = fast, right? Used to be interesting stuff here but then a drag strip opened and it all evaporated.
edit: Oh! I did pass a pretty cool maroon '66 or '67 Chevy II on the way to the grocery store yesterday afternoon... that's about it.
