Im thinking about hooking up my box to only activate Nos within a certain rpm bracket. I was thinking 2800 to 5500 rpm. An suggestions. The setup I have now is any time I hit wot. Hard on engine at lower rpms I believe.
I have the 685 mallory Hyfire VI control box it does it all. Im really happy with the features. I wired the NOS rpm window today now I just set the range. It all so has a built in 2 stage rev limiter (havent hooked it up yet) . So I can trigger say one off the brake switch set close to stall speed then a high speed one as well.
