Dual Window Switch

The switch can activate a shift light, while controlling 1 stage of nitrous, or it can control 2 stages of nitrous independent of each other. It can be used for many other applications as well, such as water injection or methanol injection. It also works with a magneto, so it can work with a high or low voltage tachometer. If you don’t have a tachometer for a connection, don’t worry, this switch can be installed to take the reading from a fuel injector wire. Then you could also drive an external tach! Best of all, it also has the ability to read from 0 to 12-volt throttle position sensor (TPS) signals (0 to 5 is standard) or 5 to 0-volt. This simple box is fully programmable from 1,000 to 15,000 rpm.

Thanks for a product that does everything anyone could ask for all built into one cool little package.  I recently installed your dual window switch on my '99 Mustang GT.  What a simple install!  When I decided to add nitrous to my car I was told I needed to purchase the following:

Tach adapter – $80.00
TPS activation switch - $99.00
or Micro switch to sense full throttle – $32.39
MSD chip for on and off RPM – $92.80

$304 in parts plus twice the wires, twice the install time and twice the confusion to make it all work.  Your one part did it all and was simple to install.  Thanks again.  For those that are not familiar with Granatelli electronics, they got it right!

 

Just wanted to drop an email to tell you I love my new RPM switch with built in tach adapter.  I just put a monster tach in my 2002 Z28 and it was a snap.  I also use one of the outputs to activate my pencil shift light.  Easy install and painless "1 system does all approach" made it easy for me. 

 

I recently installed the Granatelli Dual Window Switch on my 69 Camaro to run my tach and 2 stage nitrous system.  Went right on and install was a synch.  Worked with my HEI and MSD no problem.
