For those vehicles still having points and condenser ignition systems, the Chrysler electronic ignition is an excellent upgrade. However, a better upgrade is to replace the Chrysler electronic ECU for a GM HEI (High Energy Ignition) module. This is quite straightforward and extremely reliable. Not only does this eliminate any potential failure of the ballast resistor, the HEI system produces a hotter and longer spark, especially when used with an HEI coil.
