I hadn't thought about the "direct fire mode" not really being direct fire with the 3 channel systems like the E6X/K. You are correct though.

The best inductive coils your going to find are going to be the Bosch Motorsports coils or the Mercury IGN-1 and IGN1-A coils. The Mercury A coils have a built-in ignitor for direct connection to your ECU. The Bosch and IGN-1 coils will need an external ignitor.

The LS2 coils will certainly work with the E6X. Why would you think they're not supported. However, with any of the inductive solutions as I stated in my first post, you'll be near the limits of saturation since you'll still be driving the leading in wastespark. I know the Mercury coils require a lower charge time than the LS1 or LS2 coils. You should see good saturation at around 3.5-4.0ms. Not sure what the Bosch coils need. Any of these solutions though is going to topple the budget you stated in your first post. Again, the MSD 6 or comparable on the leading is about the only thing that will be an upgrade and fit your budget.
