hey would anyone kno wtf is wrong with my rev-limiter...i have a d16z6 and i had a buddy take it out for a little cruisin around and in 1st the limiter hit at 5500, 2nd like 58-5900
and in 3rd idk cuz i figured somthin was wrong so i stopped beatin on it. umm somewhere on i read it could be the green plug on my alternator, idk someone please help.

i would do a process of elimination and start checking all your grounds. and check your ecu, fuses. etc. Sounds like the prob is in the ecu. is it chipped or anything?

mikej94civex

nope ecu is stock as can be...my grounds r all good, fuses not sure...but would or could it be the alternator plug cuz i recently had the alternator off...and before that it went to 7200 like a champ

un do your battery and recheck your alternator plugs etc. and reset the ecu. try that, maybe something got triggered when u took off the alternator

how do i 'reset' the ecu....and thanks man! me and my buddy got to 5500 and wer like wtf lol **** sucked

step 1: take your car for a brisk drive to get the motor to operating temperature.

step 2: take your car home, and take the fuse for the ecu out. it'll more times than not be labeled, but on civics and integras it's under the hood for sure. wait 15 minutes.

step 3: put the fuse back in.

step 4: turn the car on. DO NOT TOUCH ANYTHING. GIVE IT NO GAS. let the car idle for roughly 15 minutes, or until the car is idling smooth at lower rpm's.

step 5: turn the ignition off. ONCE AGAIN, DO NOT TOUCH ANYTHING OTHER THAN THE KEY. immediately turn the ignition back on after you have gone to full off. this will store the new settings your ecu has made.

These steps will properly reset your ecu. After they are accomplished go do whatever, the new settings have been stored.

ok...i reset the ecu...nada still hittin rev limiter at 5500, and still no vtec...please someone help me

mikej94civex

vtec solenoid possibly? how can i tell whats wrong, btw this problem came up after changing my alternator and replacing the tranny ground if that helps u guys

r22thomas

mine does this too. Except I have vtec. and it limits at 6200. I think its my tach because Launch control is set at 4 and it hits a 3700. I set vtec at 5100 and it kicks at 4700ish or so says my tach. Ive always delt with it.

mikej94civex

well believe it or not i used to b able to hear my crossover, so i kno for sure it's not working. and unlike u my ecu is stock untuned as mentioned so our senarios are a bit diff, anyways my tach is fine so idk wtf is wrong.
cam pos..sensor...green alternator plug...ground...vtec solenoid somthing has to trigger this faulty crap

r22thomas

mine did it when my ecu was still a virgin.
what did you do to hear vtec I can hear mine but barely.

mikej94civex

not sure, i always could, i have a blox intake mani and that made it a but louder, nothing like a b16 but still noticable.
and this rev problem sucks soooo bad...

r22thomas

How is the manifold? Did it make a noticeable difference?

mikej94civex

na nothin crazy, made the intake alot louder tho and vtec was more noticable...and it looks alot cleaner under the engine bay too.
