Hi, DIM means : Do It Myself. I have been working a couple weeks on developing an electronic advance distributor. This is done by removing the flyweights, and locking the rotor with a setscrew, and using a micro-controller to adjust the timing, based on a timing reference signal. The micro-controller also determines the dwell time to charge the coil such that a ballast resistor is not needed. I am using an optical trigger and will also add a variable reluctor (Mopar or GM style) input. I am bench testing the unit at the moment. I have used a drill to spin the distributor, and have simulated reference signals using a micro-controller. I am using my hardware from a previous engine management system that I developed in 2003. I have removed all the fuel injection functions and rewrote the ignition code for this application. I also modified the user interface by pulling out the EFI related components. I have not spent time re-dressing the user interface, so it is ugly. The advance curves for the RPM and vacuum (MAP) are modified using two 2D tables. This will provide similar adjustments without playing with, springs, stops, and vacuum dashpots. I hope to test the unit in the near future on my Barracuda.
