N20 and fidle port

Post by convertables_10 »

Im adding a nitrous kit this weekend. A sniper kit from NOS. Im wanting to use my current tps to trigger the kit. I have my fidle wire open for now but it will be controlling fans later. On my port settings do i just follow the fans diagram and change my conditions to
tps>95
Rpm>2900
Power-on value = 0
Trigger value = 1

Am I correct in my thinking here? This is my first experience with nitrous and just want to keep the motor alive. :RTFM:

That would be correct I believe. I am using the same setup, except for the RPM which I run quite a bit higher.

Awesome. What kind of rpm you running? I am running a low rpm motor as I wont be turning it over 5200 anyways with either my tbi or the tpi.

I don't turn the nitrous on until at least 4000 rpm because I am running a 3000 stall non locking converter. I don't want to spray before launch. I redline at ~6500 so I won't see 4000 any time after launch.

Your setup is a bit different, but Fidle will get it done for you.
