Correct ballast resistor

View attachment 1715920166
Yes there is. I have been testing different ECU and Ballast combinations If I ever get it in a spreadsheet I will post it. But in a nutshell the lower the ballast/coil ohms the higher the amp draw the higher the coil/ballast ohms the lower the amp draw and also lower heat in the components. Aftermarket you really have to match the coil/ballast to the ecu used. for ideal conditions.

That is really clever. Do you have the plug wires connected to a distributor not in the picture?
