    So 92-93 are OBD1 batch fire...what about 94-95?
    I know 88-93 Berettas are OB1 batch fire and 94-95 are "OBD1.5" that are sequential OBD1 masks that are flash ECMs, not Proms. Is this the same story for F-bodies as well? The 94-95 Berettas could not be tuned by anything AFAIK.

    94-95 are SFI dual heated O2 sensors, dual knock sensors and OBDI and excellent XDF and ADX for TunerPro. No chip, flash PCM with $20 Winflash program from TunerCat.

    Just have to figure out how to use it with stock EFI distributor and your set. It has a very high tech OptiSpark distributor. Look earlier in thread for hybrid machining ideas.

    Wild idea after reading and learning about the optispark. You think there could be a way to mount the optispark on the front of a engine and run it off the crank, but use only the opti part, and then use the standard distributor on the engine your adding the injection to?


    Err...wait, no that wont work, I forgot the opti runs off the camshaft, crank will spin it too fast.
    You said in another thread not to delete bad ideas, so there ya go, I left my bad idea for all to see.
