ok i hooked up my vafc2 i know its hooked up right but then i put vtec in at 5200 and to kick out at 4800 rpm well after beating on it for a few minutes rev limiter kicked in at like 5000 rpm right at vtec switch over and then it started throwing engine codes for vtec malfunction. so i put everything back to stock vafc wise and it runs fine but i still want to be able to adjust vtec but i dont know why it keeps ****** up any help is much appreciated.
thanks ryan

 

why was your second vtec point set lower than the first?!?!

 

it was set to kick in at 5200 and kick out at 4800 stock vtec switched over at about 4900. i set the second point lower than the first so i wouldnt come out of vtec between shifts.
