    Its out of range because EFILive doesnt populate those areas of memory. If GM didnt (no need in factory OSs) and EFILive doesnt do it for you, you MUST do it manually. LB7/LLY DSPx are the same way, have to script sane values into all the new tables because they can have random or no values.

    Ive gone through and added sane values to all the COS tables. It is not using the TPS or Boost VE tables, just the N2O Monitor. N2O VE multiplier has been set to 1 so no VE corrections will be made.

    Its not the COS, it could be the Camaros dont have anything in those memory areas so you're ok not adjusting the values. This truck OS might and is causing your problems. ALWAYS fill in COS tables with sane values otherwise the motor could go boom down the road if one of the tables becomes activated.

    Dang, Joe and Andrew beat me to it. Again.

    Scarab thanks for the changes,i actually was going to do the 50% on the hi low blending.I just hadnt had that chance cause i was trying to just make it work first lol.Tanks though.I still dont understand how all the A0000 threw A0018 were out of range when its the exact same things that were already there.Not to mention i had changed some of the items that were out of range to what there set to now.

    Ok looking at all the parameter files to me those didnt change.But do you have to set them to something different first then fill them back in.If so i understand that.
    I do see that the tpsve and boostve stuff changed and a few other things.

    The COS defines some areas of flash memory that were previously not used and contain junk values (whatever GM left there in the PCM).

    Just like Andrew and Erik said above.
