    joecar you were exactly right. Even though my map showed the same units the pid default was set to SAE. When I made that change it was consistent with the map log. Thanks

    I ended up trying an LS3 Map sensor. Didn't seem to make any difference. Still very rich at idle with same VE table. I did change the parameters (Scaler/Offset). Both the LS3 and LS9 MAP sensors...

    I was just looking on the internet and saw that this sensor replaced the Bosch LSU 4.2. From what I read, it sounds like it is much more accurate than the 4.2. Does anyone know anything about this...

    Ok, I was looking at the data in my log and I saw that EQR PID for the commanded Lambda. Thanks. It was in terms of 1.15 but my pe is setup so that .88 is equivalent to 12.6 AFR. Can you let me know...

    No, it's helped and thanks for the help. I have some basic understanding of the theories but I don't know enough about EFI Live pids/data to know if it gets filtered out and when. When you don't use...

    Does PE mode affect tuning VE table

    When tuning the VE table don't you need to account for the when the pe mode is enabled? I thought all tuning was in reference to stoich (14.63) Just wondered how you determine when pe mode is enabled...

    AFR at low rpm with large cam

    Most everything I read says that you are shooting for the stoich ratio when tuning but then I also read that at low rpm large cams tend to have unburnt gas so the afr reading appears to be lean when...

    Thanks, Joe.

    So I logged 2 runs at the track with the same tune. One shows a lot of WB02 lambda values in the .88 and .89 range but the next run shows a lot in the .91 range.

  23. Does the PE effect Lambda when in open loop?

    I was just wondering when tuning if Lambda is always based on stoich or is it stoich times PE. So should you should see .86 lambda or 1.00 while in PE? Also, should the VE table at wot be based on...
