Engine Control Unit (ECU)

Had a busy couple of weeks chasing up parts, ordering parts, sorting out the our hydraulic tank which needs to go back and get all of the problems fixed!! On top of that I have designed and built the ECU. I was going to make a simple control unit using relays and a delay timer for the engine control, but decided I would end up wanting more features, and greater control. So I ended up with a PIC micro control system, the PIC monitors the oil pressure, temperature switch and alternator outputs, this way I can control the engine start sequence including heaters etc. I added an RS232 port to the ECU, and a CAN port for future upgrades, the unit works well on the bench, will try it on the engine soon!
