Well I finally got the Impulse Nypex finished. Paul really though this through and has 4 on the snow now ripping. I took it out yesterday for the maiden voyage in 3-4 ft of pow pow. It absolutely ripped and was spot on. This has the Impulse Apex complete stand alone. There is no Yamaha wiring or ecu except the coil wires and the key. Complete stand alone fuel map and timing maps. The timing maps he has built are insane. Incredible throttle response, and pulls hard on top end. I'm breaking in a new motor so I was only running 14-16 psi and all I can say is weeeeee!!! Here are some pics from start to finish.
