    Focus RS Popcorn normal?

    Hey all, been working a Focus RS and hitting some odd limiters and have some questions if anyone knows...This car was basically designed to give popcorn as some exhaust theatre (and i'm not too proud to admit that we love it) is that why i'm seeing it as one of the limits? also if anyone wouldn't mind having a look at these runs i would appreciate it...rstuneposttony[1495]1.hptBESTLOAD.hpl

    The popcorn limit doesn't really have anything to do with exhaust pops and crackles, it's a combustion stability limiter and most often you see it interfere and close the throttle if a LSPI Load Limit is being hit.

    I would log Load Desired and see what it's doing, I'd also recommend logging actual knock correction per cylinder since I'm not seeing that in your log.
