There are three swithces - which one do i need to control my nitrous so it doesn't spray during redline? i want it so the nitrous starts at like 4500 and cuts off at like7900 so its out of the motor by the time it is at the 8200 redline. thanx!

msd8956, or msd8969 . $85 and $89 dollars at summit racing.

 

Go with the MSD-8969. It is adjustable from 200-15,000 RPM in increments as small as 100 RPM. It will also save you money as you will not have to fork out and extra $30 for a 5 pack of pills, and you may have to spend more then that to get the desired RPM points you are looking for. The MSD-8969 can just be scrolled through to set the points of on/off RPM.

when i ran nitrous i had the old one with the pills kind of a pain but i ran a 3k rpm pill and an adjustable rpm pill. adjustable pill was like 15 bucks and saved alot of money.
