D.I.Y Fuel Injection Part 3

Stuffing boards and cheating on a "pot"

Last month we began the buildup of the MegaSquirt universal fuel injection ECU with some practice soldering during the assembly of the MegaStim stimulator. The stimulator pretends to be a complete engine injector pack, allowing you to test your ECU on the bench.

The board takes about four hours to assemble, not including testing time. All parts are available separately by mail order or at electronics supply houses, so it’s easy to correct mistakes. Take your time, and follow the excellent instructions from Next month: ECU final assembly and checkout.
