Ltft 100%??

**NoRemorse** · 03-20-2007, 07:28 PM

Please tell me I am logging this wrong... is it even possible to reach 100 on the long term fuel trim with out setting the lean/rich CEL???? Ok, that was a rhetorical question, I must be logging it wrong... any ideas?

lol I am pretty sure it isn't

that would mean it is running double the fuel it thinks it should.. yet not throwing a CEL, and my AFR is close to perfect. I must have something wrong in the log config.

My STFT's are all within +/-3 or so

p0171 and 172 set at 20 percent so something in your config is set up incorrectly.

its probably scanning o2 or fuel trims that dont exist. like bank 1 sensor 2 or something.

I'll check it tommarow, I just now noticed it when I went to see what would happen if I disconnected the SCIP.

I must be running a non current config, because my custom boost PID is not working now.

Check this out... my car is mostly @ -20.3

Can other people confirm these readings...

where is the SCIP???

Witt · 03-20-2007, 09:34 PM

so what happened when you disconnected scip? ive always wondered if its there to help improve electronic throttle response or just another sensor to run a dtc to check for etc failure or induction problems.

oh wait thats the Supercharger inlet pressure sensor (the one on the top of the SC) mine is pretty new would that cause the rich code?
