The classification is 94-95 (includes R). So if you want to run a 96 or 97, you will need to get them added. It doesn't specifically allow the R package trim stuff, so you still need to figure out if it was dealer installed. Beats me, other than racing them, and lusting after an '02 or '03 as a daily, I don't know too much about them.
Scott, what I have is just a stock ECU with the rev limiter bumped to 8,000 rpm. The car sounds stupid good at 8k, by the way, but isn't making a whole lot of power.
I know the Flyin' Miata computer will not legally work, as you have to bypass parts of the stock induction track.
I will be finding out if there is a "hot ticket" next week, in my search for more hp before the ARRC. I will report back if I find out anything cool...
