will STI ECU plug into non STI?
 

I've got a v5 JDM STI motor and i'm running it on a non sti ECU (Y7 22611 AE802). I have 2000 model GC8KH8D
Now with the right JDM STI ecu plug straight into the the non STI plugs? or does it have to be re-wired?
i've received the wrong ecu with my motor so i'm waiting for the right one to arrive.
I know the JDM ecu is to run 100ron fuel, so how much would it effect my car by running 98octane?
Or should i just look at getting aftermarket ecu?

thx

moved to ecu's forum

Plug it in, put it on a dyno

providing the wiring looms are JDM, then you can use JDM ECU's,

if you have AUDM wiring looms, then you will need to swap A5/A6 wires cam/crank over to make a JDM ecu work.

i'll be receiving my JDM WRX STi 555 RA ECU sometime this week its a J2 22611 AF041. The plugin are the same as Y7 22611 AE802.
so i'll still need to swap the wires over? does anyone know where i can get the right ecu wire diagram?
is there anything else that i might need to do? to get this working?

all depends on what your body loom is.

if its audm, then yes. you need to swap a5/a6.

Is the wire swap for the 3 yellow plug ecu? Or is this the Blue,Black and Grey 3 plug ECU??

I have a 97 GC8.. i want to do the same thing.. But mine is the 3 yellow plug one.. which i'm sure is diffrent to V5 STI one...
