Neil Unger.
Are you willing to change the trigger wheel? You could look at the Mega Jol= t (ignition only). It requires a 36-1 wheel, like Ford uses here in the USA= (might be the same down under).

If you're interested in alternatives in full injection/ignition control= lers, the Micro Squirt & Mega Squirt systems can both be set up for a r= otary. Micro Squirt will have batch fired injectors (like almost all afterm= arket systems for aviation engines). Mega Squirt can be set up just about a= ny way you can dream up.

The Micro Squirt controller with harness is about $400 US. The Mega Squirt = controller is about $600 US.

The car guys love them. Here's a link to an RX-7 forum page on the Mega= Squirt:
