Im used to Gen4-5 V8 stuff where intake cam numbers falling mean the cam is retarding, but on ATSV with the exhaust cam the number fall as rpm goes up also, and Id think that the exhaust cam would be advancing at high rpm??? Less time to blow cylinder down and your not going to hurt the power stroke at 5000rpm opening it too early Is lower advance or retard on the exhaust cam?
What engine/ECU is this? For the LFX (E39A) the intake cams can only be advanced, and a bigger number means more advance; the exhaust cams can only be retarded, and a bigger number means more retard. I imagine other V6's/ECU's around this time are similar. The factory tune for the V6 Camaro has the exhaust cam advancing (numbers get smaller) as RPM's increase (see post #10 https://forum.hptuners.com/showthrea...tor-Dwell-Time).
ATSV E92A, but id assume they kept strategy consistent throughout?
Yes like Gen4/5 v8 intake numbers higher is advancing cam, the home position 0 is full retard.
Ahhh so yes smaller number is advancing exh cam not retarding just like I though
