CRX B16A with I/H/E
I gave it a recent tune-up with new NGK plugs, dist cap and rotor, and wires. Other than that, no engine mods. ECU is PW0. I have an aftermarket tach.

Keep in mind, this is when the engine is warm, and it is still hitting VTEC at 4700.

Any ideas why I keep hitting the rev limiter at 7 grand? Any suggestions are appreciated!

Maybe because thats what the ECUs rev limit is?

 

Do you think I got an auto ECU?

 

yah ~ happened to me .

 

Got enough oil in it? Is the motor warmed up? It will fuel cut @ 7200 in 'safe mode' if the oil pressure isn't adequate, or if the motor is not safely warmed up......

 

are you throwing any codes? code 6 = you probably have the ECT and the vtec oil pressure sensors switched. if there's a code 6, the computer keeps the cold start rev limit on full-time.

Only code is a 23 (knock sensor).

 

you're hitting rev limit at 7k because you have a pwo ecu and that what it's set to hit when you're throwing specific codes.... "safe mode"

So you think it's in safe mode because of the code 23?

 

yes thats what mine did when i had codes.....
