Ok, I have a 97 EX Civic, D16y8 and a P2P ECU. Today I installed a Apexi VAFC, programmed everything according to the manual. I didn't mess with fuel curve or anything drastic. Tonight I'm driving and go from 1st to 2nd gear fine at around 6k rpm in 2nd the car feels like I hit the rev limiter which is past 7k rpms. As soon as that happened my check engine light came on. Any ideas what I may have done? or didn't do for that matter. Thanks in advance for any help or advice.
