Ok so for some reason my civic is acting like it has a 2nd rev limiter. Its suppsoed to rev out at 8300, Well for some reason , it will hit some "magical" rev limiter anywhere between 5-65.k rpms. WTF? It was solid at 6500 for a while but today it was doing it at 5000 then 5500 then 6000 i dont fucking get it. Any input??

Car is a ej1 w/ Built b16 turbo.


Rep will be givin

 

Have you checked for boost leaks?

 

yes i have ONE boost leak (waistegate is broken enternally) but it was doing it before i got the boost leak, other then that i have no other leaks

 

i read online i could be low on oil? I was low so i put oil in it nothing changed.

 

A bad boost leak will cause make the car feel like its getting a fuel cut, or hitting a rev limiter, sometimes they're rather violent. I'd fix the wastegate problem and check for split or loose couplers in the mean time. Are you throwing any CEL's?

 

Ok this is what happened, The car was on 15lbs running like shit spittin and sputtering (not enough fuel) Turned it down to 10 and it was fine no spittering or sputtering, MEANWHILE IM STILL HITTIN A LIMITER AT 6.5K, Ran it a couple times then i feel it cuttin up, im like i think i got a boost leak, i look sure enough, im only vacing to 5 not 10plus like i useually do.


Like i said it was doing this before then, i think it might be my timing its pretty advanced and just might be the tune?

 

this is probably why the guy sold it. i would contact him first and ask if he can pin point it first so you dont waste a grand on something you dont have to

 

I talked to him and he thinks its fuel cut.

 

I would stop messing with the boost levels, honestly. If the car hasn't been tuned for that setup its not safe to run it, period. Fix whatever problems the car has first and then have it professionally tuned. And if you must drive it, i'd keep it out of boost if you like your motor. my .02

 

it sounds like fuel cut to me. has it been tuned?
