Thread: "I Dont Know" Cam Selection Finding

    Default "I Dont Know" Cam Selection Finding

    Finally fired the engine for the first time with the Terminator install over the weekend. For some reason, I could not get the engine to idle for more then three seconds. I played with the throttle plate adjustment screw and the idle A/F Ratio to try to give it for air & fuel, but nothing really worked (I did the TPS Autoset every time). If I revved it up manually, it would stay alive though. So decided to reload the GCF Wizard, and instead of picking the street/strip camshaft choice, I just went with the "I don't know" selection. All the sudden the motor fired & idled perfectly. Not sure why the "I don't know" setting made it idle, and the cam choice that's closer to what I actually have doesn't.

    My camshaft is a Comp Cams unit, 226°/236° @ .050" with 112° LSA around .547" of lift.
    FYI: I have not synced the timing yet to the handheld from the damper, but that's next when I can get it on the lake.

    It's was just a more mild selection that has less fuel (lb/hr) in the Base Fuel Table.

    That's kinda what I figured. My cam specs are right on the lower end of the "Street/Strip" selection in the handheld. I think it started at like 224° at .050", but it was "224° & up", which is a pretty broad spectrum considering there are some big cams out there. Are there any disadvantages to leaving it this way after I sync the timing and drive it around? Just want to make sure I'm not leaving any performance on the table, if the computer would run the system better if it "knew" what my cam specs really are.

    No.

    It doesn't matter. The Learn Table will self-tune the Base Fuel Table anyway.
