I quit my job and took two weeks off before starting my new one and decided to take those two weeks to finally install the new SpeedyEFI ECU in my Miata. The car is a ‘91 that has a ‘99 BP4W engine in it and running on the 1.6 electronics. The SpeedyEFI should help me take advantage of the extra power of the 1.8L engine

I installed a new water temp gauge, wideband O2 sensor, GM IAT sensor, and some other goodies.

I got it running and tuned just in time too, i have a track day this weekend
