i was out tuning my buddies built b16, so i have live tuning open and everything right.. his afr's are fine to the 10 psi that we were tuning for that day (11.7), but crome is saying his duty cycle is at 150 some percent? He has a walboro 255 and rc 550's. i think thats enough gas for whats going on right now. Is there some kind of script error or something? Has anyone else experianced this? 2 other cars ive seen on live tuning have been fine so im pretty curious.

 

Crome's Duty Cycle has never been spot on, but in recent versions it is pretty close.

Generally when I see high duty cycles like that it is the fuel pump that is crapping out of the regulator not functioning properly.

 

crome 1.2.5 addressed the duty cycle errors at all?
