Is there a difference in wrx/sti i thought as long as both are top feed

Don Clark

There is no difference, if Hatch08 had read the full description not just the title line...................

Theoretically yes, they should fit just fine and they do include the STIs on the drop down list of cars on their ad. But you may want to ask them the question why they are advertised as WRX. Then you have to add postage, import duty and VAT at customs etc

Hi Don
quick question, if you don’t mind: is there a difference between the USDM and UK ECU on STIs post 2008? And would a USDM ECU plug into a UK car or is the harness different?
Many thanks in advance!

Don Clark

Physically they look the same although I haven't checked for any variation in pin out.
Each region usually has it's own map and different bracketry for LHD/RHD (hence different part numbers) and is usually updated each model year.
There appears to have been a change for MY10 onwards as complete part number changed, not just the last three digits (this maybe that the mounting bracket is now supplied separately but still has separate ECU part numbers for LHD/RHD)


You can check below to see if anything is difference in the pin outs - not all pin out info maybe shown as the ECU covers other functions as well.
