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
