My stationary Rev limit (launch Rev) is set at 5400 rpm. Sometimes it works perfectly normal. But then at other times it doesn't work at all for some odd reason. I'm thinking maybe the ECU is not working properly. But I'd like a few more opinions before I go ahead and replace it. Any comments would be appreciated!!!

are you running V7? If not, it could be your clutch switch.

 

Ok I tried the Fix and still it's not working all the time. yes I am running V7 96531706 and have been for the last 6 months But this only started in the last month.

Is there a way to test the clutch switch?
