i just got my rpm switch in and i tested it with a test light and i drove it out side my house and it worked perfect, i have the rpm switch connected to my nitrous master switch and i wired up my zex to the rpm switch and when i got it all hooked up i hit the switch and it revs to 1500 rpms, it didnot do that when i first hooked it up and tested it with the light, so i am stumped, the only thing i could think of is that my master switch is hooked up to a orange wire (drivers side under the kick panel), mabey it has something to do with that, any help would be great.

 

it about has to be something with that orange wire like i am taking to much away from it and it is doing something with the fuel or timeing so i need to figure out what that wire is.

 

anyone?

 

Your engine itself actually revs to 1500 rpm without you touching the pedal?

 

ya, it is when the soleniods r not grounded it runs some power throw the zex box to my tps sensor so i dont know what zex expects?? something might be wrong or u need to ground it all the time? but how could u run a window switch? i am about fed up with zex!!!

 

i will try to call zex in the morning. we will c how it goes.

 

The tps sensor getting voltage can't cause the rpms to jump, are you sure its not spraying the nitrous?

 

y not i think at wot it is getting like 8 volts and if 3 volts r getting threw it will raise the rpms.

 

ya i dont even have my nitrous lines connected

 

How will it raise the rpms? your car isn't getting enough air to feed it for those rpms.

 

well it is i jumped the box right to the battery and when i did it reved to 1500

 

i dont know i give up

 

I would expect perhaps a small jump in rpms from extra voltage at the tps but not 1500 rpms sounds like something is way miswired, give them a call hopefully theyl'l know better what the systems doing.

 

i dont give up i did some more testing and found out it is for sure the box and i will call zex in the morning

 

it is not miss wired i ran the kit for a few months. it is something to do with the zex box or the way they made the box.
