just got my nitrous installed today, nx 75 shot, dyno tune window tps,dyno tune switch center, & nx purge. i set the dyno tune window switch up "like i read to in a previous tread" but i could not get step 8 to read my voltage. it read 808 or something like that. well my buddy say's every thing else is right lets just go try it... bad idea we cruse down the street and first gear doesn't go off at 4k witch its not supposed to, but second gear give me a boost at 4k and then 3rd gear really hits hard at 4k well everything was ok till i went to slow down. the throatily got stuck at 5k rpm and im sure it has something to do with the voltage but if some of you nitrous gurus could throw some thoughts or what might be wrong since my car wont let me change the volt to 4.5 . what could have been the problem to make the throttle stick like that? thank you in advance for helping
sorry lol, it just wont let the rpms go back below 5k when i spray, and i cant get the voltage to read on the dyno tune window switch "step 8" it just keeps reading 1.0-1.1 volts i don't know what i did wrong its all wired correctly
Ah, I've experienced that problem. If and when that happens, just shut your engine down. Leaving it to spray your nitrous into the engine bay when not at WOT or at the appropriate rev range will result in a boom.
I think you may have tapped the wrong wire for your throttle position sensor, if that's the case.
yea lol i had the boom the first time i was stuck at 5k, but i just went out and fixed the problem, what i did wrong was on step 8 the wot step i didnt rev the engine so it was at 0.8 V i went in a big parking lot and revved the engine and got my actual WOT voltage where it needed to be, now it works great!! i love it thanks for your help i really appreciate your strait forward answer and not the typical "use the search engine" lol thanks again
