I have a twin-turbo OBD2 NSX.
You do not have to go stand-alone or otherwise invest in a fuel/timing solution that requires laptop programming if you don't want to.. There are "bolt on" controllers that will do the basic trick. (For more serious applications (beyond the 450hp mark) though it's probably a really good idea to go with the stand-alone's.)
If you want to go "bolt on" (which I think is fine if you're going with the basic Bell kit), here are my recommendations:
For fuel, the Rebic 4 additional injector controller. Very adjustable & easy to program on the fly, and gives you a decent amount of info/feedback to work with for tuning (peak holds, alarms, injection simulator, boost/injector/rpm display, etc). I'm very happy with the unit I'm running and it took very little time to program/dial in.
For timing retard, you (and anyone else with a forced application who has an interest in adjustable timing retard) are in luck.
There's a timing-retard controller available for the NSX as of now. A while back, I called up a company who had a general-application retard controller and had them customize it to work on the NSX. They finished prototyping it on my car about 6 weeks ago, it's worked flawlessly since then. You can dial in retard based both on boost and rpm.
I will post a message on this forum with all the details sometime soon (things have been crazy lately, haven't had the time). But in the meantime at least you know a timing retard solution is available and that unlike a pre-programmed chip, it's fully adjustable on the fly.
Best,
