Hi,
When the ECU learns from knock and retards the ignition to save engine caused by bad petrol etc. is the worse map used from then on forever?
Ie does it "unlearn" and increase power again when better petrol is back or does it just use the learned map from then on for ever?....
Just wondering if resetting the ECU would give me back some power which maybe the ECU is afraid to use... - i used crappy non E5 petrol for a while and now i'm using E5 again (which it was mapped for) i am wondering about this...
Does the "disconnect battery negative and pump brake to drain power" method of resetting ECU back to base map work on 03 STI or is there some other way? How long would you have to hold brake?
Thanks
