how to tune corrections for the apexi afc neo


it chokes at 4k rpm at regular acceleration!
but in first gear going i could get the rpm up to like 6k almost WOT!
each of the rpm are set at 0 now!

it seems a bit weird that the check engine light comes on when it starts choking and when i slow down it turns off.

thanks
