STFT's sending unwanted fuel....why?
Here is the next issue that I have encountered. STFT's dumping unwanted fuel. Don't know how to change this. Here are tune & log file. Once the STFT's start dumping fuel, she starts burning fuel in the exhaust pipe again. You will see in the log when the STFT's start fueling. Please help
Bank 2 02 sensor is gobbed up due to my previous injector problem (from previous post). Am in the process of replacing it.
Ran a side by side, tune file to log file & found that the EFILive ECT/MAP table for OL fueling is registering twice the ECT that is noted in the F9 list & the EFILive dash gauge. For this reason, the PCM is going into richer fueling & eventually engine protection fueling.
Will try to calibrate the software. Anyone who knows a quick method, please reply. Thanks
Here's the latest log & tune file. Run them side by side & you'll see what is noted.
This must be a software problem becaue it only occured after I downloaded the 7.5.5 upgrade?
I took a very quick look at your log file...
Hmmm... your wideband does show it getting richer as STFT's increase...
Are you sure you got no airleaks...?
Are LTFT's disabled (I haven't looed at your tune file yet... later tonite)...?
If they are, then why are LTFT's showing non-zero...?
In the scantool, go Help->About and see what build version is it.
Also maybe try a full flash.

I'll look up the version to confirm. Have re-loaded earlier today w/ same issue.
Checked both Scan tool & tune, both are 7.5.2 (build 36) only because I tried to go back to the older stuff in order to get rid of the problem. Apparently, the tune file that was re-used after the re-load didn't change.
Did a full Flash 7.5.5.72 scan tool & tune tool; same result. Here is the tune file & log. Open both together & start the log (it's short). Watch the ECT on either the F9 or dahboard & watch the ECT vs MAP, OL fuel table. Log ends w/ 49*C Scan tool (which matches the engine temp) & corresponding 120*C commanded on the ECT vs MAP, OL fueling table. Now, I just turn the car off as soon as the AFR starts to drop. This avoids the damage & exhaust fireworks. Have also sent an e-mail to EFILive support.
Does the same thing happen with build 84...?
I meant: do a full flash of your tune file to the PCM.
