Hello evryone.
I am thinking of buying a secondhand prodrive proformance pack ecu for my 2004 wrx.
The numbers on my ecu are :6c 22611 ah751 112200 5142.
The numbers on the prodrive ecu are :b3 22611 aj830 112200 8820. and its out of a 2000cc 2005 wrx.
Apart from the keys having to be recoded does anyone know if this will work? or am I wasting my hard erned?
Many thanks for any info.

 

I think 03-04 ecu is different to 05. They are listed as different maps on open ecu sites.

 

just for anyones future info I fitted it and its working great. thanks for the reply though daz.
