yo in a stock b18c (p72 ecu isnt the redline suppose to be 8200rpm??? in my car i am geting my redline @ around 7300rpm any1 kno wat could cauz dat??? does dat have to do with distributor timing?

 

hmmm...deja vu...I could have swore I've seen this post before.

 

I have a b18C1, and when I had my P72 in there I was redlining at 8500. Now I have a P30 with S100 and I redline at 9000. But I dont know why you are redlning low. Bump for some help.

 

sounds like you have a timing problem in which the ecu is not letting the motor rev past 7300 to keep you from damaging the motor

unless you have an ls ecu in your car which has a redline of around 7300 as well

 

How can i fix it, i am sure its a p72 ecu, i feel it has something to do with the timing, how can i kno for sure?

 

drive it to a lube shop and have them set the timing at 16 degrees

 

your tach could be off as well.. if its an ls ecu it wont hit vtec

my civic did that.. i thought it was redlining at 6000 but the tach was off

 

check ur crank timing

yes, and the crank timing because you may have jumped a tooth on the timing belt

Is it hitting the rev limiter at that RPM? (The rev limiter caused the engine to cut in and out.) Or will it just not rev beyond 7200RPM due to lack of power?

I dont think his car would start let alone run if it skiped a tooth and if it did run it wouldnt get that high up in the rpm range.

Depending on the car some could, but i doubt your friend skiped a tooth then reved to 7300 tho did he?

no because he was driving a single cam that couldnt rev that high

im just giving possibilities of what could be wrong, im saying to check timing because it could be off due to one thing or another
