hi everyone newbie here i'm in a pickle! Ihave a 440 mopar that i put the tbi and ign system off a 89 454 on to it. I haven't started the motor since i put the throttle body on but i did run the ign before to make sure there were no prob there.(I'm not a mopar nut i also have a 78 3/4 with a 2001 5.3 in it i just hate fords)My question for everyone is What is the best way to tune the 89 system to the 440? I have the complete harness off a 91 5.7 truck (and yes i switched the wires on the tps for the diff tb) I'm putting the heated oxy sen. So now what do i do to the ecu,does anyone know of an existing tuner prog for this setup cause surly someone has already done this.OH yea I forgot it is cur sitting on a trailer in my garage and i have a 88 dakota with a 3.73 gear 3" exh alum rad std rack and beefed frnt coil springs to put it in. so i'm trying to get it right before i put it in! Man that was a lot of data

Sounds like your best solution is to pay a visit to and see what the guys there can recommend.

Ambitious project, but should be pretty awesome when you’re done.

Pictures!! Please.

Burning chips sucks. I would use an emulator from Moates or do a Dynamic EFI EBL upgrade to make the ECM flash capable.
