i have a mugen copy chipped p28 for my b18c1 with a skunk2 itm, i prefer to use this because then i dont have the big flat spot from 4400-5800rpm like i do with the p72. vtec engages at 5700 and its suposed to redline at 9200 but it keeps the stock revlimiter at like 8600 or somethin like that. i know its not just a bad chip because i used my friends chipped p30 and it did the same thing. ive used this ecu in other cars and it worked fine, and it used to in mine. what could be causing this? help please

 

so your saying your ecu (9200rpm redline) actualy redline at 9200 in other cars except your own?

hmm, never heard of that before. you have no check engine light right?

i hope you have a good valve train to rev that high.

 

well i just have itr springs and retainers right now so i dont wanna take it up to 9200, just like 8700, and no check engine light, and ya it works in other cars but not mine, i dont get it. im goin to be gettin some new cams and valvetrain but i wanna figure this out so i can rev higher. help me please. TIA

and remember it USED to work in my car, i dont know when it stopped but if i had to guess ited be around the time i got my pistons in if that helps.

 

up, i need to figure this out!!

 

Try checkin your tach.... They get out of calabration after a while...

 

thanks, anybody else?

 

up again i need to figure this out.
update: i now have a CEL its my o2 sensor, and i got a vafcII and my tach is way off in some areas, but the vafc shows my redline at 8200, just like the tach says. i dont get it, this ecu works in other cars, just not mine

 

come on guys, somebody has to know about this

 

Can we see a pic of the P28 (the inside of course) where the chip goes. Can help you out better If ic an see it.
Also you not listing enough info for anyone to help you. It's kind of weak in the area of explantion, but then again I don't really understand your question.
If the chip revlimit is set to 9200, then it is 9200 no matter what ECU it is in.

 

I say you have an ecu reprogramming person (such as mua) have a looksy at your program and change your redline point

 

but i tried a another chipped ecu that works in my friends car, but it still kept the stock redline in mine, so i dont think its somethin with the ecu, because ive switched them and none have worked

lol..no problem.

 

i believe if you remove the pill completely then your ecu redline will take over

can anybody confirm this? if so thated be tight, then i dont even need to wait to get another pill

 

first check that

and does it sound like a red line and no power at this rpm on vafc2 right


well mine used to do that at 6200 or below and it was since the rebuild some junk got clogged in the vtec solenid screen???

or also can be the dizzy acting up???

I would check it out

mine would work on my friends car too and it was that

after I cleaned it I could feel really power again
