DIM Electronic Advance Ignition

Desmo900,

Thanks for the encouragement. It seems it is always hard to find play time.

I need to box it up and do in-car testing. I have two platforms, one for bench test without case, the other for in-car. I need to upgrade the hardware for the in-car, for the Bluetooth 3.3V power source, and add a couple parts for the coil current limit. I have tested in car with USB-RS232 dongle, and works well except for a slight hesitation at low speed take off. The coil current limit will enable extended dwell time at low speed, with out excessive coil current. Prior work with 4 cylinder engines and different drive circuit did not have the problem. I have changed coil driver component for V8, and need to add external current control. I have bench tested and all is well.

The wife is very busy with a garment design for a fashion show, she is my driver so I have to wait for her to get free. We are both project people. I follow safe tuning practices :). It would be horrible to kill someone, or damage the Barracuda, just because of the distraction of testing. Around here defensive driving is essential.
