So i've been getting a jolting problem which randomly occurs when accelerating. It's as if fuel has been cut, but it's not.
Since i've got my ap, i've been monitoring KR and noticed that usually when it jolts, it's knock, though sometimes it's not knock (yet to log this), but just looses power for a brief moment and then kicks back in again (very weird).
In this first log I was on WOT, and I noticed that for some reason the AFR's are WAY too high. This is not always the case, but on several times when i've logged this knock, afr's have been around these values, not dipping when I go on WOT. Also noticed fuel trims are kinda crazy too.
this is a ots stage 1 sf+tih+ic map
In the second log, it is the same map. This time I was not on WOT, rather around 20% Throttle Position and not on boost what so ever. Would expect afr's to be as they are in this log, and the fuel trims aren't crazy like in the other log this time. I have NO IDEA whatsoever as to what would be causing the knock in this log.
Any thoughts/help would be appreciated.
I will strive to do a MAF cal as soon as I can to try clear that side of things up and smooth it out, but for now i'm a little confused as to why I'm getting all this knock!
Cheers.
