I am in either of these two camps:
Back to completely stock ECU, no extra wires or sensors. I ran a stock ECU up until last year (when I installed a crappy JET chip), and I did pretty well stock for 4 years.
The other option is replace the EPROM chip or reflash the existing ECU. I can see this option for the speed governer problem, however, I never hit a speed cap (governer) in my Integra (could go 125mph), and I dealt with the 7100rpm rev limiter. Yeah, that sucked sometimes, but I dealt with it.

Either of these should be easy to enforce, just open the box and look for chip or extra wires, etc.
This way, we limit the money spent, back to 'cheap' racing.
