I want to know if there is a rev limiter in a 7730 computer other than the regular one that is the fuel cutoff limits.

I have a motor that want turn past 5100 - 5200 rpm. It sounds like it goes on a rev limiter? The chip program rev limiter is set to 9544 rpm. I have used two different computers and two different chips but no difference. I have changed ignition boxes also and even put it back on regular GM ignition.

I have changed cams in the motor and I think that the cam is the problem but I was wondering if there was another rev limiter. I have even changed valve springs on the motor to try that.

 

Just something to check, the same thing happened to me. The ground on the back of the left cylinder head was loose. I kept getting a popopopop at 5000. Ive never hit the ecms cut off to know what it does.

 

Thanks, I will check.

 

no, from what i've read there's not really a way to cut spark with this code.

i had my boosted car do that till i gapped the plugs down to .020, then it went away, so i knew i needed a cd box
