    Hi All,

    I installed a built 6L80E into a 2008 Pontiac G8. The car wasn't running for 5 years, so idk if that could be causing this, but just want to put it out there.

  2. Control Module Voltage VS Control Module Voltage (SAE). Difference?

    Hi,

    I noticed on my scans that I had 'Control Module Voltage (SAE)' being logged, and the value for it was all over the place. 17volts, 19 volts, one scan showed 1 volt. I started to freak out.

    Looks like adjust my timing DID do the trick. It shoots up to 3k rpm now, hits a wall - but I'm pretty sure that it is turbo lag now. Drives ways better

  8. Filtering out commanded EQ ratio during transition period?

    I'm wondering if it is possible to filter out the area below outline in blue. It's the point where Commanded EQ goes from 1.00 to PE mode 0.75. The data in my scan is getting skewed (showing lean)...
  9. LS2 Not Going Into Power Enrichment (PE) Mode

    My friend has a supercharged LS2 I just swapped into his 1972 Camaro. It came out of his 2006 GTO, which had been professionally tuned, so we yanked that PCM from the GTO and used it for the swap.

    I solved this issue, it was 100% my fault.

    I'm guessing I deleted the PID, and when I re-added it, I did not do it the correct way. I had to transform the INPUT 1 input, now it is working
