RB Concept V.12 5 Port Tuning
Hey guys
When i run the car around the parking lot the motor runs great. Once i hit the track and do some laps and bring the car back into the pits the idle is very high. I am gonna guess and say one of the niddles is to lean. Is it the low or high niddle? I run 20% with a #5 (hot) plug from RB.
Thanks

But youll find the motor overall will keep power. If anything it was probably just a high idle and when you heat the motor up it makes your low-end leaner which makes it idle high.
Just try simply taking the idle speed down now. That should fix the problem. Another way to tell is after the straight if it keeps rpm up high for too long....

Then i saw this

Big difference in niddle settings....
Then i was able to let it idle the first tank.
I will look into this some more today and see what i come up with.

Good. Also thanks for the response im trying to hone the tuning skills and stuff like this helps me figure out my own motor issues.
But yeah high idle , its almost too obvious sometimes thats its the idle screw needing adjustment. But your right a lean low-end can also produce the same results. Its trial and error really.
