    LS2 E40 - not enriching fuel for PE mode??

    Strange issue here. I have a 2006 GTO with LS2. Working on a MAF tune for some very mild upgrades. What I'm noticing is that the ECU isn't commanding the PE EQ Ratio set point when it's in PE mode. There is a value to log whether it's in PE mode or not and sure enough, it says it's in PE mode yet the commanded EQ fueling doesn't shift. Anyone else deal with this issue? I probably have something dorked up...

    Told you I dorked something up.

    I had my Enrichment Ramp Rate set to 0. Any value lower than 1 impacts how fast this ramps in. Obviously zero is not correct and was causing my issues.
