I don't know if any of you guys have used tuner cat, but I'm having some trouble. The car seems to be running rich , and somewhat hard to get it to idle. I just would like some direction on afr's , fuel trim and VE tables if possible. By the way, the car is a 96 Z28 with an LT1 new 383 with 10.5:1 CR, 230/236 , 583/586 112 Comp Cam.

AFR's at idle should be 14.7:1 or slightly richer in open loop. What do you have the idle set to? Raise it at least 200 rpms above stock, to start. A cam that big is going to want less VE at idle, so lower that area of the table a bit, try 10% to start. Is this an automatic or manual?

The idle is set at 1000 in park, I did get it to idle somewhat after it warmed up , also found my throttle plate screw seems to back off, I may need to put a lock nut on it.

Thanks !!
