I have an 08 G35 (VQ35HR) and Im getting my stuff together to do a 100 wet shot on my car. No worries...Im getting it all tuned...im going to go one step colder on my plugs...and I will have a nitrous map put in and it will all run on a window switch. So before anybody asks that...im stating it lol. I been doing a lot of searching over here since not many of the G guys are doing any kind of nitrous, but im getting conflicting info between various motor platforms. What im looking for is the TPS wire and the rpm wire. Is the TPS wire the green wire on the driver side throttle body? RPM a red wire with yellow stripe on cyl 1 coil pack? I have a Zex tps module and i read that our tps is a decreasing voltage where as the zex unit is an increasing voltage unit yet people are using it without problems but not really getting into exactly what they did to set it up. Any insight on this would be greatly appreciated.

 

Yes and yes, if you're DE. I don't know if the HR wire colors have changed or not.

As far as ZEX specific info, I don't have any personal experience (well, I helped install one 5+ years ago, but that's it).

 

Ive seen many people use the Zex without a hitch so i know its feasible haha. I may just wind up calling Zex to verify it all. But figured you guys could give a little more insight. I have located a green wire, and the rpm wire...so those wires are there but without an FSM i dont want to just to tapping into wires without knowing for sure, ya know?
