Help with GTR Nitrous Express kit install

SG4247 · 09-13-2019, 08:28 PM

So, I have the GTR dual plate kit from Nitrous Express.

This kit includes a digital TPS WOT switch that has a wire that should go to the ECU at a TPS tap somewhere...

Anyone know where to find this TPS junction point on the ECU?

The FSM will have that information. See link in my sig.

Thx! I was looking for more detail from someone who had installed this little digital TPS switch before.

Also trying to find a good place to tap into the engine RPM signal.

I have the RPM window switch which needs that signal.

So, I plan to switch the nitrous on between 3500 at WOT, and then off at 7000 at WOT.

I will shift the 7AT at 7400 rpm.

At least thats my plan at the moment. Hoping to save wear and tear on the trans this way.
