Ehhh you'll be fine. Enrich fuel and retard timing ALOOOOOT. My first night ever on the track, car did good just need to adjust timing more to get more power. I launch at 6k and get wheel hop bad as you can hear in the video so I tightened up the rear suspension to see if that will help next race night. I got 2 more nights of racing and then its time to go 3/4 tube chassis and 4 link susoension.

You have to wire it up its already in the ecu just need to hook up the wire. If your harness is like mine (microtech harness) its the blue and black wire. I have mine on a toggle switch which activates the switch on my clutch. So at the track I just flip the toggle on and everything takes care of itself.

Wire might be a different color on mine cuase is a LT9.I have play with the settings before but without using a switch and i do get some bouncing but not pooping.
