5th gear + vtec = CEL..?
 

when i hit vtec in 5th gear, my CEL turns on.


got any idea why..? it kinda started happening after installing apexi VAFC. settings are only correction 1% / lower vtec point to 5300rpm

if i vtec 1-4th gears, it doesnt turn on.

car is 2000 USDM ITR.

USDM B18C5 Computer, 1mm bore increase, 11.5:1 pistons


got any idea why..? is it because im running a slightly leaner than factory..?

Pull the code and it will tell you why its coming on... that code is there for a reason lol

Berz out.
