Nitrous window switch controlled by factory pcm!
Nitrous window switch controller via the pcm!
THIS WILL ONLY WORK ON AN M6 Trans Car. The pin output is the same as a shift soloniod on an automatic, that is why it wont work on and auto.
With Efilives software,
Take standard 5 pin relay and hook pin number 30 to one wire of the WOT switch on throttle body, pin number 87A to open end of the wot switch, then, hook up a positive wire to pin number 85. then connect pin number 47 on the RED computer connector to pin number 86 on the relay.
Use these settings,
the turn on for nitrous
Master Enable- ON
PCM Output- YES
High RPM- set desired nitrous shut off time
Min ECT- -40
Max On Time- 409.6
Low ECT- -40
Gear Ratios- set for active gear you want it to control the nitrous shut off.
Delay Time- all 0s
RPM vs. Gear- set all gears to the same desired RPM for nitrous to shut off per gear.
RPM vs. Gear vs coolant warm or hot- set all gears to the same desired shut off RPM
Min TPS vs. Gear- 0
Max TPS% vs. RPM vs. Gear- all 100s
Now, this wont control the low end rpm activation "but it is still controlled via the wot switch so it is just like it was before this mod so it is still safe" but it only allows the nitrous to flow until the max rpm is hit and the tps still has to be at 100% for the nitrous to even be activated and will shut off at what ever you set the rpm light to come on at.
Any questions Just ask.
Great info that's some thinking. Here's a way to control your low end on also 6-speed only. I have my gags disabled and shift light on and set max rpm to 3500 and first gear to 3500rpm and 2nd, 3rd, 4th, 5th an 6th to 0rpm. This is my launch light. Now couln't you set all gears you want to say 3500rpm and use the wire running to light through a relay and tie into your set-up for an activation on RPM? Sounds doable to me.
