BBYLMBO Posted July 29, 2023 Report Share Posted July 29, 2023 HI, I am having an issue with my K20/K24 hitting the rev limiter at 7200 rpm which I should be able since it is set to 8600 rpm. On the dyno, it would break up and then hit 8600 rpm. There were a few clean runs where it didn't break up. As you can see in the log, it would hit around 7000 rpm and then spike to 10000-15000 rpm causing a rev limiter cut. I found a broken wire on the exhaust cam sensor and fixed it which worked for a bit then it started again. I am also going to replace the Crank sensor to see if that can be the problem. I am not throwing any triggers. I have attached the log file. Hope someone can help me out. Thank you!

DerekAE86 Posted July 29, 2023 Report Share Posted July 29, 2023 You should attach your tune, as well as a Trigger Scope. It's possible the signal isn't very clean and the threshold needs to be adjusted. But it certainly looks like a sensor/wiring problem. And the fact you've already found one broken wire would make me check the rest. Quote Link to comment Share on other sites More sharing options...
