Car won't rev past 6k

[K20A EP3]

Got my Skunk2 70mm exhaust put on on friday and when i was making the u turn right before i got home i got on it in 2nd it got to 6k bucked. I didn't drive it all weekend, then when i was on my way to work this morning it did it again when i was in 3rd. Im not sure why it's doing it. Im using 93 octane. Im gonna try to barrow a laptop today and find out whats going on. Any Ideas?

i am assuming you have k pro? datalog it and check it out for sure. i had this problem when i forgot to plug the vtec sensor back in on the back side of the head but mine was cutting at like 4k-4500 rpm.

[K20A EP3]

Yea i can't wait to get off work and check it out. I got on it a right after i got it put on and there was nothing wrong it pulled fine. We didn't mess with anything besides the exhaust when we put it on so im confused

check you oil level....

check you oil level....

Agreed. Most people that hit limp mode after a hard turn have low oil. You need to check it frequently. If that checks out, run a datalog.

[K20A EP3]

Oil is fine just checked, plus i check it at every other gas stop and i just changed it like 2weeks ago.

I just checked the sensor it is on good. My vtec is set around 4500 too. You can hear it turn on but then it hits 6k and bucks.

Just went out on lunch break and it's still doing it in 2nd and 3rd. But i can be going 60mph drop it in 4th and take it past 6k. This sucks I cant wait to get off wok and datalog it. any ideas

Any CEL's?

Have you used Kpro to "zero out" the TPS?

My K20A leans out @ 6k as well (limp mode). Got it tuned and everything is well right now.

No.. Im not sure on what you mean by that. Could you explain

Yea i think thats the problem. I have lean protection turned on. Im goin to turn it off today or atleast lower it.

[PyroElectro]

mine did something similar but my problem was the cps.
i just have the k20a3 though.

I'm glad I never modded the engine, *whew* all these complications

i know right?
My next car will be stock except for rims.

My boy brought his laptop over yesterday and soon as we hooked it up it started rainin its ass off so we didn't datalog anything, But we lowered Lean Protection it was On set at 14.2. So we lowered it to 12.0 hoping it would help. (I WISH I KNEW MORE ABOUT KPRO) So i m on my way to work this morning goin 60 and give it gas in 6th and it bucks at like 3200, It's worse now. I baby her home on lunch break and put the stock Type R PRC ecu back in and she runs like a champ. Called Brady at CCC and he told me that it probably threw off my whole tune. He told me to bring it back and he could fix it. But for $350. Will it really be that hard to fix? When i get a datalog i'll post it up if anybody is willing to help

You lowered the lean protection into an area that is rich, of course you will go into limp and have issues.

Those numbers are in reference to the A/F, 14.2:1 is where it was set, and you only made the protection hit when the engine was still very rich.

I suggest you search out every little bit of info you can on Kpro and read that info at least three times. Kpro isnt plug and play, it is plug and play and play and play.
