ok
So today I just got my p72 ECU and thought that finnally got nothing else to worry about (WROOONG!!)
First of all I still not getting VTEC secondly, the car red lines at 7200RPM :dunno: and third, the car sometimes stalls at Iddle and the firs couple of thousands RPM seem to take forever...
personal hypothesis:
1 Vtec does not kick in maybe because of a loose wire (didnt have time to check since it was dark)
2 Car is redlining at 7200 because.... I dunno y tha fcckkk!!!!!!
3 Iddle... ??????????????????
please HEEEEEEELLPP!!! im going crazy
thank you

 

anybody?
please tell me what you think!

 

read the serial number on the side of the ecu and tell us what it is.

 

Also, did you replace the timing belt? Did you do the work? Any CELs? What are they?

How do you know you're not hitting VTEC? This is the B18B w/ B16A2 head, right?

 

Timing belt was replaced, no, didnt do the work but i was around, CEL because of O2 censors, the car goes up to 7200RPM no difference. we disconect the vtec solenoid and run it and was the same as when it ewas connected!
this is a b16 block b18 head p72 ecu

 

Check your actual codes. It may be more than O2 sensors and those could directly be contributing to your cutoff problem.

 

what other problems??
any example?
how about VTEC?

 

Get the codes, that will shed more light on the situation. Stabbing at potential problems in the dark is very inefficient.
