Any of you guys ever hear of the MSD6-BTM or Crane hi-6 w/TRC-2 being used with any success for the turbo boost timing retard on our 7's? Don't know how this would work especially w/ our trailing spark but I've always wondered.

You really shouldn't be using those blasted things on a stock Turbo II.
They are really touchy for a turbo'd NA.
We tried messing with a BTM on a SC'd Honda, and it was a royal pain in the ***.
Adjusting the **** would induce too much retard or too little.
In the end, going full stand-alone EMS is really the proper thing to do in terms of ignition control.

The leadings fire twice in each ignition cycle.
Each rotor face effectively sees 3 sparks - first leading, trailing, wastespark leading.
The leading spark is the primary ignition spark for each ignition cycle.
The trailing spark cleans up the combustion, and it's used primarily for emissions.
The trailing maybe contributes about 10% to the total power output - from SAE paper written by Mazda R&D.
Thus, using the CDI on the leadings will give you the most significant gains.
It's also easier to install a single-channel CDI box on the leadings.

best ignition box is the HKS Twin Power:
http://www.hksusa.com/products/?id=842
but, and this is just my opinion, ignition amplifiers should only be really used after you have identified you have ignition issues. happens in some high-boost applications, or high-rpm applications. if you need it for a stock car you have some other issues to work out...

I think the Autronic 500R or the MoTeC CDI 4-channel boxes beats it hands down.

i have not heard of the autronic unit.
but, can the Motec be used with a stock ECU? i thought you needed the Motec ECU to use it? i don't really know much about that.
also, i think the HKS might be the only unit to provide both CDI and Transistor Ignition, but i don't know how much that is really worth...

This means you just need to fire a signal into the 4-channel (max) box, and it'll spit whatever back out.
