Well my good friends at NX sent me the new smart sensing TPS switch. I've had my run in with these TPS switches before, and to be quite honest I thought they were trash. Up until I got this one. After months and months of shopping the market the only thing around was the Zex system. No offense to the owners of the kit, but a purple kit is just not my style. Any color (other then lime green) would be better.

Anyways back to my story. I got the kit in, and it actually comes complete. The Relay, longer wires from the TPS (Previous versions were slightly shorter) wire tap, and alot of splicers, and connectors.

Two bad sides to this kit:

1: Wire tap, way to small, really hard to get the TPS wire into it, without removing it from the TB. I used a different style and it worked fine, and easy. Also LS2's run really hot, so I dont suggest you try to wire tap it, or even start on this install until its completely cooled.

2: Not sure what the connectors are called, but they are the circular connectors that you bolt or screw onto things to make a connection. The other end taps into your wire. Basically the size of the circle is WAY to small to even bolt it into anything. I went with a larger diameter connector and WHAM fit perfectly on my ABS box, grounded nicely.

The instructions are complete! it doesnt get any easier then this, if you can read you can install this thing. Got it all wired up, hit the arming switch, did the programming (really easy, just push the gas pedal down twice) and WHAM done. This switch kicks on about 92% of the end of the pedal. Which is great as there is always a slight delay on the nitrous solenoids. Throw a window switch (like me) and this is the ultimate electronics available for the LS2... no surging of the solenoids, no guess games, just really easy.

I'll be starting my write up tomorrow, got some really nice pics and some install tips, and I'll also make a PDF.

This really is an easy (I cant stress this enough), and great working product, thumbs up to NX for this switch, I cant stand those stupid WOT switches sticking at the bottom of my pedal... drilling the brackets etc, waste of time.

Have you tried the FJO trick switch? Just curious... my FJO should be wired up pretty soon, and was just wondering if you've already gone the FJO route and like the NX better. I'm a big fan of NX stuff... since my entire system is NX.

Not yet, I have heard good things about the FJO setup as well. I have also heard it is a nightmare to wire, from a few people. The nice thing about this switch is its simplicity, I mean literally it cant get any easier to install it. The fact that it learns everything in smart mode, means you cant do anything wrong. Nothing I hate worse then the nitrous solenoids surging, and you dont have piece of mind with the other kits that they will open, or close at the correct time, drive by wire is alot worse then cable driven tb's but anyways its going to get 100+ track passes in within the next month, so I'll report back.
