    Wont Start In Open Loop

    For some reason i cannot get my 05 vette to start in open loop. once i put it in closed loop i cant get it to start, but while its running and i turn closed loop off in the scanner i see the computer go from 14.7 commanded to 1.47 commanded and kills the motor. anyone else have this issue before? Basically I want to tune this thing in open loop, but cannot get it to run in open loop whatsoever. wont even start.

    mods are big cam and full exhaust

    All of your open loop tables are set to 10? 10 times richer than 14.7 is 1.47......... These are multiplier tables not what you want open loop to be 1 would be stoic...

    2005 Corvette's stock have some of the open loop tables set at ~10 and some at ~0.1, making it work out to ~1 when they are multiplied together. You've changed the 0.1 ones to 1, but left the 10 ones as-is... so right now fueling is off by a factor of 10.

    Change the open loop gas/alcohol tables to 1 and give it a go

    There's no reason IMO to flat line all of these tables.

    Yes, I would put these back to stock and then set the higher operating temps to 1 just for dialing in fueling while in open loop... Personally, I'd just use closed loop and 02 corrections to dial in your fueling tables - that's if you plan on it being put back into closed loop after words...
