For those wondering about the VQ30 ECU...
The reason I say to run that ECU, is simply to reduce the wiring nightmare. Few reasons... The VQ35 ECU uses drive by wire technology. This would mean wiring in the gas pedal and making up a subharness for that. The biggest thing, is that ALL VQ35 ECU's come with NATS (Nissan Anti Theft System), which uses a transponder key and matching IMMU. Basically, you would have to get a ECU, IMMU and key, ALL from the same vehicle in order to just start the car. Now, if you have a Consult, or access to one, this isn't such a big deal. However, it still has to be wired up.
If you use the VQ30 ECU, you can get away with using the VQ30 pulley. You have to make a mount for the crank trigger pickup sensor.. but, it's not hard. You don't have to switch the timing cover over.. You use the VQ30 flywheel and VQ30 pickup sensor. This will let you run the VQ30 ECU.
So, using the VQ30 ECU drastically simplfies this install. Yes, you will lose your VTC.. but, it's not THAT big of a deal. You might lose 5-10ft lbs in the low end/midrange. Using a 96-97 ECU means that I can have clark at JWT tune me a nice map to suit the VQ35's demands. So, besides the loss of CVTC function... it's really the best way to go IMO. I mean.. I don't mind wiring up a VQ35 ECU and harness... I had to wire up the NATS system in the Sentra.. and get that working. But, for the average Joe... I don't think most people would enjoy wiring one up. Unless you're really good at reading/interpretting wiring diagrams and voltage/resistance values, adding in resistors/etc where needed... this wouldn't be for the faint of heart.
