Im wondering if its better to get a JWT ECU with the nitrous or just leave the factory ECU but just cut the Speed Limiter wire in the ECU and check engine will come on? I heard if you run an aftermarket ECU with the nitrous theres a better chance for detenation...Well opinions and reccomendations would be great!

 

If you're just getting your feet wet w/nitrous, best to stay with stock ECU and 75-shot or less. You don't want any more ignition advance w/nitrous.

Put in NGK plugs, copper-cored, one step colder. Be sure your fuel pump is working OK and you have a fresh fuel filter - upgrade to 300ZXTT if in doubt.

That's enough to get you on the strip and survive the experience. Tires will be a problem. Stay AWAY from fuel-cut RPMs.

Enjoy the ride.
