I just received the Edelbrock Nitrous System. Out of the box, it promises 75 extra horsepower for $621 (+ Nitrous gas).

The kit came with a WOT module and a Fuel enrichment module. Each needs to be wired into the -Z-'s electrical system.

Attached is the wiring diagram for the Fuel Enrichment System. Can anyone tell me or guess by looking at this how the Fuel Enrichment Module MIGHT work?

Thank you.

The Fuel Enrichment Module works by getting the computer ECM to see that the Air and Coolant temperature is very low e.g. as you would experience when starting the car on a cold day. This results in more gas been pumped to the injectors providing the additional fuel required for the nitrous.

Does your Edelbrock system work well? I have been working with Edelbrock as firstly the WOT module would not trigger and open the solenoid. This was rectified when it was discovered that the WOT module trigger voltage was set too high. Now the WOT module works but not the fuel enrichment module is not working resulting is detonation etc.

I wish I had purchased the ZEX or NOS wet systems.

Hey there, just got done installing the Edelbrock system. However I ran into some problems with the wiring diagram that was supplied by Edelbrock vs what my wires look like in the 2006 350Z. I have to wait to call Edelbrock on Monday and talk to a tech rep. We have everything hooked up and connected. But the 50 shot didn't really hit (that I could tell). I just wanted to start off small and work my way up. But until I can verify that the fuel management device is working... I'm on hold. Anyway, does anyone have any suggestions for wiring the Fuel Management Device.... you know the one that has to be cut into the ECU.

That is my only complaint with Edelbrock at this time. They need to update the wiring diagrams for the year of vehicle you ordered for.

Looking for an updated 2006 350Z witing diagram of ECU and Fuel Management Device!!

Take care

I had the same problem with my 2005 Z. Edelbrock has a supplement wiring diagram for your year model which they can e-mail you. Do a test on your WOT module whilst the ignition is on and your car is in gear or D if you have an automatic. With your accelerator pedal down and the nitrous switch ON you should hear the solenoid valve checking open. If the solenoid valve does not open either your WOT module wiring is incorrect or the potentiometer in the WOT module is set to high (or the WOT module is defective as was the case with mine). The 50 hp shot gave me a 0.5 second 5mph 1/8th mile improvement and you will feel the kick when it comes in.

I eventually converted my Nitrous system to a wet system as I was getting (detonation/pre-ignition/missing) sounds in my motor at higher RPS with the nitrous on. I put in iridium plugs and 101 octane gas but this did not improve the performance. I also had engine starting problems. Once I converted to a wet system the nitrous worked perfectly, and when I removed the fuel enrichment module I had no more starting problems.

If you do not want to cut into your wiring harness at the EMU 9under the dash) you can get from SUPERCHARGERS online http://www.superchargersonline.com/content.asp?id=175 and wiring harness adapter. If you want to convert to a wet system and not cut into your fuel line hose this company also has a great fuel adapter block.
