Default 2012 WRX STi Stage 1


I flashed the Perrin Stage 1 93 Octane map about 300 miles ago. The car feels great and pulls much harder than stock. However, I logged a few WOT third gear pulls and noticed consistent fine knock learning above 2800 rpm. Is this anything to be concerned about? The logs are below:


The car is stock other than the tune. Let me know if you need any additional information.

yes... it looks like its pretty agressive and your fine knock learn is consistantly pulling a little timeing in order to not knock.
also, boost is a tad high for a "conservative" stage 1 tune.
see if they can adjust it or give you a 91 octane map.

Thanks hutch. I'll contact Perrin and see if they will make adjustments. I can't imagine my car is the only one having issues with this tune. This shows the importance of datalogging and staying on top of your engine's performance. I think tuning is awesome but definitely want to keep the motor running healthy.
