Sorry about your allergies, Gordon, and the heat, Lane.
Pictures as promised. First the ECU case, slightly thicker than one pack and longer than two packs of cigarettes. But still, very small as far as an ECU is concerned.
No, I don't smoke people! Here are all the components that came in the box:
Clockwise from top left: Arduino Mega board, the "brain", the Speeduino UA4C, ECU board that interfaces the car to the brain, a USB cord and the case, connectors, the case endplates(beautiful and copper-clad for interference-blocking), the idle stepper driver, VR conditioner, and finally the bluetooth module.
I've got a bit of soldering to do, and firmware/software downloading. Then some testing and harness-building. This is going to be done over the winter off-season.
