Are you willing to change the trigger wheel? You could look at the Mega Jolt= (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 controllers,= the Micro Squirt & Mega Squirt systems can both be set up for a rotary.= Micro Squirt will have batch fired injectors (like almost all aftermarket s= ystems for aviation engines). Mega Squirt can be set up just about any way y= ou can dream up.

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

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