Det

[damx]

Sled is a 16. Pipe, head, porting. Ran awesome for 300 miles, then today I'm hitting det like crazy. Would happen at just over 1/4 throttle. Any ideas?

Bad fuel?

Add octane booster and see if it goes away

Ya I'll add some race fuel. But it's strange that it's happening at 1/4 - 1/2 throttle.

Drained all the fuel out, got fuel from a different gas station and all is good now.

I've had clutch weights cause DET on my 12 Pro. Must of been just enough weight to trip the knock sensor

 

[sumtinwong]

what are your RPMs

Anything rattling in the engine compartment ? Sensor can hear that as Det.
