    Default 2019 GMPP LT376/535hp file

    I hope the management is ok posting this file. Interesting on the engine dyno, cyl 2 was showing false knock and reduced the timing to around 8 degrees BTDC and also killed hp to around 460. Another interesting issue was correcting the AFR/Lambda between cylinders with 8 widebands killed 10hp every time we corrected it Time constraint job so it's off the dyno and gone.
    I was simply a bystander on this job so I can't share too many details and I assume some would like a gander at the stock file. Ended up around 565hp once finished.

    This document from 2015 makes me wonder if this is involved.

    Hiya GMPX or anyone,
    I can't seem to find the thread where we discussed this type of thing before, I read out a stock 2018 Camaro ZL1 E92A .bin file the other day and wasn't doing any tuning to it and totally forgot to read it with EfiLive so I could have a gander at the VVE tables. Ross or Paul, could I send you my .bin read so you can convert it to an EfiLive file for me? You mentioned I am missing something in my E92 .bin reads that doesn't allow EfiLive to open it. Always trying to learn, and see the latest GM stuff but I don't have access to the car anymore.

    Or if anyone has something similar in EfiLive format and is willing to post, I am interested in looking at the VVE tables. The earlier LSA and LS9(much better) VVE tables leave a lot to be desired.

    I'm reading the doc.

    How was it established that knock on #2 was real or false...?
