Breaking my "no posting on vacation" vow...

The IGN-1A will work with either Microtech or Haltech directly. Really any system that allows a falling edge output with programmable dwell control. No external ignitor needed. The Microtech X4 box is simply a fancy name for external ignitor. If you already have the X4 you may be able to run the standard IGN coil (no built-in ignitor), which is essentially the same coil but a little less expensive. However, the IGN coil needs an ignitor that is capable of supplying a large amount of current. The internal ignitor of the IGN-1A is rated for 19 amps. You'll need an ignitor with that kind of rating to allow the coil to work it's best and to ensure you don't burn down the ignitor itself. I know there is at least one guy on efi101.com that has used the IGN-1A with a Microtech system.

Ian, you can run these without a CDI box and get a similar amount of spark energy at the plug. The upside over CDI with the inductive coils is that you also get a longer duration spark. Win-win. If you have the Autronic, go ahead and run it. Otherwise, unless you're running over 30 psi of boost or perhaps straight methanol, these are the coils I'm recommending.

The coils will ship with a connector plug and pin set. The installer will need to crimp the terminals on the wires and assemble the connectors. If that's something you don't feel comfortable with, we can assemble a pigtail for you.
