65. It is choice time again. In this case, you will decide whether to populate the high-current ignition driver circuit. This circuit can be used to drive a single coil in a distributor application. In conjunction with an appropriate input signal (from a VR, Hall, or optical sensor, or even points), it allows you to eliminate a separate ignition module, such as a GM HEI 7 or 8 pin module, and run the coil directly from MegaSquirt.

If you aren't sure what output circuit to use, check to see if your ignition is on this list and follow the instruction in the link if it is:

• GM HEI
• GM DIS
• Ford EDIS
• Ford TFI
• Bosch 0 227 100 124
• MSD 6A
• Direct Coil Control
