    Please look at log and advise. In spool up heavy accel i will get KR. Don't see anything out of sorts. if i stay in it, it goes away. Not sure if it is false or not.(tires sometimes starting to break loose) do you see anything? i do have a hops switch that triggers second fuel pump at around 13psi but i do not see any volt spikes, gross lean or rich. possibly pull some timing??
    Also is there a way to log fuel pressure? assume with 0-5v pressure switch into com board.
