Start with the fuel manager 5 turns out. When at full throttle, hit the button. When the motor doesn't bog, you are tuned. Do the set up while riding(not on a stand). Start the sled and hit the nitrous button with the nitrous bottle closed. The motor should bog. This way you know your getting extra fuel. Less chance of a burn down.
I used lithium batteries. They lasted all season.

Be careful with this system. make sure the batteries are new every trip. I had the batteries get a little low and the fuel selinoid quite working while the nos still sprayed!!!! Very bad. to tune just find a nice spot hold wide open and hold the button for about 3 secs it should start to stumble and miss a bit turn the fuel setting in a half turn at a time until it runs clean. now your fairly close if you have egts now you can fine tune with temps

the temps will be different for every sled. find out what your egts read after a good long pull under full throtle and use this as a base line. i like to have my temp drop by about 50 when im on the button that way i know im safe
