COP Ignition Development

The wires were added to the board and test fit in housing. If this becomes a reality, a sealed panel mount PCB connector will eliminate all the internal wiring. Building the circuit has provided good information on how to improve the geometry. If the width is increased slightly, the coil drivers could be placed four on each side. Depending on how much room the connector takes, the enclosure length could be reduced.

At this time the enclosure is just for the prototype. Building it was not easy, so not planning a second at this time. The initial test of applying 14V, for test of communications, and sensor inputs went well. I have tested over an input range from 7V to 18V. The unit switches current to ground to energize external devices such as coils and relay that are powered by an external feed. The current supply to the unit measured less than 0.05A. The coil and relay supply voltage is external to the unit.

If any metal working folks have a simple chemical way to turn polished aluminum anodize, dull black, please advise. I have thought of shooting with flat black paint then wiping of the tips of fins, but not sure how that might look involving the corners. Also not sure how well paint will stick.

I have installed a 2x4 Molex MX150 sealed connector on the coil drive wires, but my crimps are not perfect. I have place an order for a correct MX150 style crimp tool. I was hoping to use one of my many crimp tools, but that did not work well enough to continue.
I ordered a Molex 63811-1000 service grade crimper, I wanted the 63811-6000, but it is $300.

Next is to build a coil cable test jig with signal taps, for bench testing using spark plugs. If that goes well the next step is making a harness for on car tests.
