Hello, everybody. I need help. My ECU flashed improperly... After rebuilding the short block, my car (WRX STI 2008) doesn't go as it should. It's become weaker than simply stock WRX. I need help... There is no one here in Russia, who I can ask to reflash the ECU. I want to do it by myself... What should I begin with?
I'd be very thankful if anyone replied...
The configuration is:
BC 79mm crankshaft; BC rods; Manley platinum lightweight pistons, 9.8:1 CR.
AEM cold air intake, decatted downpipe and catless axle back...
I suppose that the problem is in pistons, The ECU can't get on automatically with CR 9.8:1... Turbocharger is stock... It doesn't blow... Only 1.1 bars... On the third speed gear the car dies....
Thank you everyone!
