Subaru impreza wrx ecu part no a18-000 d37 22611 ad190

it also says 8S on the back of the unit.

i want to get a 2nd hand unit to try a stage 2 EEPROM re map chip in and have heard that the units may differ between the wagon and salloon modles, any advice will be much appreciated cheers.

 

also are the ecu's different between wrx and uk if i were to fit one of thede re map chips.
cheers

 

If your going to put a chip in it, then it won't matter what model the original ecu was for as long as its got the same plugs
