    Default Injector Flow Rate Table

    I just got EFILive and i have a few questions.

    1. Should i put my Injector Flow rate table back to stock before doing the AutoVE tuning? I have stock injectors

    2. Its a 1998, so do i put the MainVE in Map "A" and BackupVE in map "b"?


    I did some practicing and when i left the IFR table like i had it and added 5% to the VE tables. i was running really rich. 10.9-11.2 and sometimes even richer, but when i put the IFR table back to stock it was still running rich but when i would get about 1/2 throttle it would get really lean, like 16-17. I was going to try and raise the VE another 10% but ran out of time.

    any help is appreciated.
    thanks!

    Yes if injectors are stock put stock #'s back.

    Yes the maps are set up like that.

    how about my main VE table? it had been tuned from the 400-2800rpm range to help with my idle.

    should i put that back to stock also and then raise it the 5% or 15%? to start autoVE tuning?

    also my octane tables are changed? should i put those back to stock also?

    thanks

    Changes to the IFR table and the VE table effect each other. If you are returning the IFR table back to stock then yes, you should return the VE back to stock as well. Probably best to increase the VE table by around 5-10% across the baord prior to AutoVE tuning.

    Once your fueling is correct, then you can use the idle calibrations to dial in your idle.

    Don't return the spark tables - unless there is a problem with excessive knock.

    thanks Paul,

    I changed the IFR and the VE tables back to stock and did a short drive to test it out. It is running 9.9-10.1 AFR in the lower rpms and at idle and that was without raising it 5%-10%.

    Do you think i should lean out 2800rpm and below and raise the 3200+ by 10% before i start autoVE? Alot of white smoke was coming out with all that fuel dumping in there

    thanks again!

    White Smoke? That isn't from running rich. The smoke should be black and your exhaust should really smell nasty. White smoke is more of an indicator of anti-freeze getting into the combustion chamber.

    I'm a newbie to tuning myself and haven't attempted the AutoVE process but I'm assuming your car was running o.k. on your previous tune before trying AutoVE. I'd put that tune back in if it was o.k. first off before you damage the cats (if you have them) and find out the source of your coolant leak.

    It would probably help if you would list your modifications as this has a direct bearing on the your tuning parameters. LOL.

    Get it as close as you can estimate before AutoVE. The only reason I said to raise it was to prevent the opposite happening: running at 16, 17 to 1 AFR.

    Also, check {B3605}, {B3632} and {B3633} to make sure they are not the source of your over rich condition (at startup).

    You may want to check your original IFR table using the IFR calculator spread sheet at http://www.allmod.net/hpt/injectors.xls
