I am about to buy a nitrous kit (leaning towards a nx kit or hsw) and I know all these kits come with a activation switch that turns the nitrous on when the throttle blade hits the arming piece at WOT. My buddy had one on his car back in the day with the arming switch and had a ton of trouble with it. Is there any way to tap into the TPS for activation at WOT instead of using the metal arming switch? Im sure this has been answered before but couldn't find it. Would there be a best kit to use for this if it is possible? Thanks for the help guys!

 

Yes there are several controllers that use TPS for activation. I use the MicroEdge + with my Nitrous Express kit.

 

The Microedge looks like it has almost everything you need. Window switch, TPS switch, A/F shutdown, gear lockout, activation delay and all. It almost looks too good to be true and it is cheap! lol. How is the quality on these pieces?

 

my dipshit speedshop mounted it under the gas peddle.....nothn but trouble.

i put a new one in the bolt hole for the removed egr stuff and it i got it perfeclty aligned to be hit at wot.

not sure what theedge cost but i got my window and wot off ebay for $50

 

Its only like $170.

 

Its a very good unit. It does everything as advertised. I have the "+" for use with progressive setup if I want.

For timing I use the "resistor mod" to pull timing when the system is armed so I don't need 2 tunes either.

 

Sweet. Thanks for the input.
