    ecu question? dohc swapped guys

    got a question for the dohc swapped people.

    if i decide to go dohc with no turbo (not ready for FI yet) i know the stock ecu will work but im looking to 5spd at the same time and dont want a CEL.

    would the evo ecu work on a n/a application? if so would i need to flash and tune and buy the boomslang adapter? or could a 3g ecu work ok?

    well i think 3g ecu would be my best bet money and time wise anyone think differently.

    if your not goin turbo then most likely and even if you do ive heard you can flash the evo rom onto one of them.

    i was thinking evo but i would need a taxtric cable and boomslang harness and a few other things right? but if there really is a fix for the 02 ecu then ill just do that instead but i cant find it anywhere.

    you dont "need" a boomslang i didnt use one and mine works but its a pain in the ass without one but yea you would need an openport cable but im pretty sure you need it either way. and a fix? do you mean for the manual swap?

    yes if i wanted to use my ecu but do the manual swap with no cel.
    spd frk said something about using some auto tranny parts but i have no idea what thread its in and searches arent helping me find it. ill pm you reik with another ?
