Put a NOS 2 stage window switch on my 5.3 swap car, went through programing with it just hooked up to power and ground fine. Then after wiring it to all in car the damn thing flashes "pro 9" after holding both buttons then show 1stage rpm on and won't do anything else. I shut power off to it and it resets and displays TPS voltage and if i start car it show voltage and rpm (which is what I need to change now).

 

Is it the NOS MINI 2 stage

You need to get with Kyle@NOS. He is pretty knowledgeable and does a good job with tech.

 

I called the terch line yesterday. don't know who I talked to but he said take it back to where I got it and exchange for another.

 

Try talking with Kyle. He is by far about the only person at Holly tech I would deal with.

If not I can try and get with them for you.

 

OK I'm a retard. My car is a typical 30 year rundown car that I'm driving while rebuilding. Slowly improving EVRYTHING. One of those projects on the to do after INDY LSX in oct is rewiring the car. so while looking for a 12v ignition wire to tap into, I mistakenly tapped into a wire from the flasher. On my digital volt meter it looked like a good 12v switched supply, but just the slightest load would cause it to pulse. Window switch got mad and wouldn't allow me to program. Good 12v supply and problem solved.

 

Awesome! Glad its working well.
