ECU and Loom: Are they interchangeable?

[127 Boy]

Hi!
Since I´m managing to put the 4AGE in my little KP61 in stock form, I need to know if the ECU and LOOM from an MR2 or FWD ´4AGE can me useable in one RWD 4AGE, since they are cheaper and more available!

Thanks in advance for the replyes!!

Yes, you can use the ECU and loom from a front wheel drive but you'll have to alter the loom to fit. It won't be a straight fit in that some of the wires may not be long enough.

I've got a bigport running with a fwd loom (adjusted), and a JDM bigport ECU.

Tks Chrisso!!

Really nice Info!

Will search for MR2 ECU + LOOM then

Just make sure you get the right loom/ecu for resistor pack/no resistor pack, and map vs afm.

I assume you'll run a map sensor, so just make sure it's a map sensored ecu/loom.

With the resistor pack, it doesn't matter what you ran before, as long as you get the resistor pack and use it if that's what the ecu/loom was designed for.
