I finally got around to hook up my LC-1 Wide-band on my 04 Z06. I have the WB simulating the NB in bank 2. I did a few logs and they have generated some questions.
This log was yesterday, shortly after installing the sensor. I did a couple of WOT pulls. After looking at the log I am puzzled at a couple of things. First is the AFR. Max shows 87.21 AFR?! I imagine this is an issue with the LC-1, but what would it be? So do I rely on its read out? Next is the HO2S mv... both banks appear to be accurate, so I am confused to the extremely high AFR reading.
9177
The next log was this morning. It was a cold start with normal driving, to a short bust on the expressway heading to work, then normal driving and once I got to a safe spot stopped logging. Everything appears to be normal. I did not log the WB, I probably should have. Then again I woke up 20 minutes prior and rushed so I can make it to Dunkin Donuts :hihi: BUT the question I do have is my LTFT's seem to be as close to zero as ever before. Could this be because of the accuracy of the WB? Here's the log.
9176
One off topic question I have is, when I select vehicle speed PID, it displays MPH in the Data (F9) tab. Yet when I view the Dashboard (F10) its in Km/H. It never used to do this, did I accidentally change something?
Thanks guys!
