slight KR problem I am running AFR 205s milled .018 for a 63cc chamber and an XER 220 224 114 +4 on stock bottom end.
SCR 11:1 and DCR 8.9:1 with a .034 quench on 93 Octane
With this combo I am getting very slight KR at about 4300 but mainly when I let off the throttle or let off and reapply.
Thoughts?
Brad mentioned Transient air but I can't find it in EFI live.

Out of curiosity, did you tune your VE table? Are the values in the that area of the table 'somewhat' different than the surrounding areas on the table? I would also look at your spark tables in those areas as well. Assuming you have DFCO enabled, you could try disabling it to see if that makes a difference. Fueling during transition is somewhat more complicated as the process of metering the air is less accurate. That is when it can become more important for a proper VE table as it is given more weight for fueling calculations. Just some food for thought. Do you have a scan?
