    case learn when swapping camshaft and injectors?

    someone on another site mentioned that I should do a case learn after swapping a camshaft.....others say only when swapping ecm's

    any thoughts on this? will it hurt anything to do so anyhow?

    crankshaft is case learn. make sure you follow the procedure perfectly or it won't work.

    foot on brake, etc etc? I think it does say complete or something but I haven't done it with the 3.x

    It has run well from the get go, even with all the stuff that I changed. Tonite was the first time that I ran open loop, no maf and no stft, and I managed to slowly creep in on a really good vve only tune.

    If it were mine, I would probably run it mafless , open loop...it's that close. I set the idle down as low as 450 rpm and it just sits there puring, while jumping between 2 cels ...very nice, so far, especially for someone as clueless as I am with all this.

    I have a ways to go yet, but so far so GREAT !!

    thanks again
