Window switch problems

[19984V]

I can't get my nitrous to spray right.

It's kicking in 5000+ RPMs

My window switch is set at

3.3
6.4
2

Help!

What brand rpm switch? MSD ? IF it is,make sure you dont have the switch wired to send 12 volts to the solenoids. You need a relay to be switched on by the msd window switch. More info will help!!!

How do you have it wired up? It sounds like either the window switch is bad or you dont have a very strong tach signal due to bad wiring connection.

MSD window switch.

The tach reads fine on the switch, its pretty accurate up to ~100 rpms.

I didnt do the wiring my tuner did

How to i make sure its not 12v?

the window switch can only handle about 1.5 amps . Solenoids are typically 6-7 amps.and a relay for the solenoids must be used. If you dont have a relay wired into the circuit ,take it back to the tuner to fix.The window switch will shut itself off and not operate correctly if wired directly to the solenoid/s. Good Luck!
