I need a little help here..
I'm Running a B18c1 with 11.5 to 1 Wiseco pistons and stock fuel system exept for an adjustible FPR..
I appear to be getting Pre-Ignition only at low RPM under under a load. This only started after i put my Chipped P28 ECU in ( no Knock Sensor) . I could just swap my P72 back in but it runs alot better with the Chipped ECU at High RPM. I do have an A/F ratio gauge ( not sure if it's worth a Sh*t) it shows rich at the point i get pre-ignition. I'm running stock NGK ITR plugs.
I'm still kinda of a noobie at this so if i'm leaving out important info please let me know.. Any help would be great.
Thanks
