hello everybody im installing my zex nitrous kit and im not sure on how to connect the DynoTune Two Stage RPM Window/TPS Switch to the zex box has anybody on here done this? i have search so please dont me. also what would be a good rpm signal to connect 2? thanks

 

relay might work.

 

rpm settings: 3.3k to 6.5K

*you don't want to go any lower than 3K rpms, and have it stop a few hundred RPM's before red-line to make sure you don't bounce off the rev limiter.

use the TPS/window switch on the low current side of the power relay to the solenoids. It's a switch that connect the low current side to ground when the rpm/window conditions are met.

what wire on the car do i connect to for the rpm. some people say its on the injectors but im not sure which one or what colour. thanks for help more would be apresheated.

 

search for the pin number on the ecu. its either 50,52, 60,62 cant recall which. youll have to set the window switch to 1cyl i believe.

 

im going nuts! ok coming off the dynotune box theres the rmp wire, tps wire, ground wire and 2 channel wire 1 and 2. then off the zex box theres +, - and the tps wire. ive seen diagrams where they have both channel wires from the dynotune box connect to the one tps wire on the zex box. but then i read that i need a relay and i have to connect to the - wire. man im confused

 

ok i got an email from dynotune and they said i should connect the channel 1 wire to the ground wire of the zex box. so..... would i still connect the the tps wire from the zex box to the tps on the car?

 

the rpm wire will be one of the wires to the coils, the tps wire will be the green wire to the throttle position sensor, you pretty much have to think of it logically, whenever the dynotune box meets its requirements to turn "on" then it will feed power to the switched side of the zex box...

 

this is how i did it thanks everbody for the help
