This worked flawlessly in my Rotrex supercharged Miata until I upgraded to a MS3Pro PnP.
This ECU allowed the operation of a newer 1.8liter engine from a 2000 Miata (BP-4W) in my 1993 chassis. It operated VICS and the cooling fan, but retained the older design alternator control.
With proper internal modifications (jumper wire swapping) this ECU will work with any Miata through 2000.
Also included is 5’ of vacuum line, a t-connector, and mounting screws
