Well I finally finished the Nitrous Express Proton installation. It was both really simple and extremely challenging. The basic installation is a breeze.... just time consuming. However, the quirks of our trucks and the extra safety features I needed caused for some headaches. But not it is done.
Before installation I had the TRD blower, 2.8" URD pulley, NST overdrive, 7th Injector, DTLT headers, URD TCAI (modified), and the Map-Ecu3 to control everything. So before I started the nitrous install I wanted tto change my plugs over to Denso IKH24 Iridium Spark Plugs (2" cooler than TRD plugs) which of course meant pulling the supercharger.
While the S/C was off I drilled and tapped a 1/4 NPT hole in the S/C between the two 90* bends as seen below. I then installed the Nitrous Express Shark nozzle.
I then mounted the solenoid on top of the fuse panel. I had ordered some -4 An fittings, tee's, and 90* elbows from summit racing. I used these to route fuel from the 7th injector pick-up to the solenoid fuel input. The N2O and fuel outputs from solenoid were hoooked up to the shark nozzle. I then installed the 10lb tank brackets behind my rear seats (drivers side) and drilled a 3/4" hole in flooring to run the nitrous line from the bottle to engine bay. This line was secured underneath the truck and up into the engine bay and finally connecting to the N2O input on the solenoid. Payed special attention in keeping line from getting kinked or routed close to anything that gets hot. Physical install complete.
Wiring was a headache due to my mistakes along the way... but finally fixed it and it works. Switch was installed in dash to provide a (+) output. Run to passenger side and out into engine bay. Map-Ecu3 switched output 2 (-) was also run into engine bay. These were feed into a relay to reverse the polarity of the Map-Ecu3's output to (+). This (+) output was run to drivers side fuse box and attached to nitrous express relay as the switched input. The Map-Ecu3 was programmed to arm the switched output 2 under the following conditions...
Throttle >90%
RPM 3500-5300
Pressure 1-12psi
Speed voltage (will be set later to maximum speed that truck shifts into second under WOT from launch)
After everything was properly hooked up and output from Map-Ecu3 was verified with test light first before hooking into nitrous relay, I took it out to test it.
Started with 30 shot. Very noticeable change once nitrous was activated. 2nd gear went from shift to redline FAST! Drove around for 15 minutes or so activating it from different speeds and running it up to 110mph. No problems... A/F stayed in the high 10's and low 11's as I have it tuned to do. Then let truck cool down a bit and swapped jets to a 50 shot and repeated test. WOW. Don't know if it was only the change of jets or that coupled with the sun heating up bottle to better pressures but it was much more impressive. Tested this setting several runs and everything perfect again.
So it works... got to tiddy up the wiring a little
