Dang it... I imagine that this would not work for a 95'+ NSX would it?? Also, I'm curious why you're selling it...

I am not sure, but my instinct is that it will work since you will be using this ECU. I am not sure if the 95 have more O2 sensors, etc. I am revert all back to stock incase I need to sell the car.
You cannot use this in a 1995 car. 1995 went to drive-by-wire so the previous ECUs will not work without replacing or modifying the engine harness, replacing the throttle body, adding in the idle air valves, installing a throttle cable, retrofitting the 91-94 cruise control, etc.

The bottom line is 1995 and up NSXs need a standalone ECU to properly tune them.
