    Default New to EFI need some pointers plz

    I have a 99 Camaro z28 auto with a stock tune, i installed a 3200 converter LT headers 3.73 gears. just got my efi and was looking at the tunes that have been provided but didnt see much on just for the blot ons ive done and what things i could do to gain a lil HP from tuning. would like to find how to delete the rear o2s and change gears and what i need to change for the stall in it.
    thanks for you time!

    Hello,

    My mods are not all like yours but I may be able to help you with shift points and TCC lockup.I run a 9" rear with 3.70s but it will be close.

    Hope it helps.

    From the tuning tool pdf:

    DTC
    Diagnostic Trouble Code. There are literally thousands of different trouble codes. Whenever a malfunction is detected by the PCM, it is usually recorded, and if the fault is emissions related, it will illuminate the MIL (or check engine light) on the vehicle’s dashboard.

    Thanks so much for the info... but if i go to where i change the gear ratio and tires size will the computer automaticly change the shift points and the speedo to the new ratios? And since i have a 99 ecu whats the deal with the 2002 OS upgrade is that something i need to do? and i see everyone making he torque reduction to 0.00 that something i should do to?

    Take the time to do some homework,

    Instant answers isn't the best way.

    There's a good thread about A4 tuning right here in the Forum.

    http://forum.efilive.com/forumdisplay.php?f=60

    If you have questions then, either post them or PM someone who can give you some good pointers.
