Hello Paul,Mark Caviezel here. Say, just when I was warming up to=
Mazda rotary power, I see that Tracy Crook is retiring from the reduction
and electronic ignition supply biz. What are the options?=

There are lots of options on electronic EFI and ignition out there.
Megasquirt is the best known with the most free support.

I will be building a side draft carb based on the existing slide
throttle and Holley parts. As soon as I get the turbo compound engine
done and tested.


I will also be building an improved Ross gear box copy.
The improved gear box coupling is being tested shortly on a p-port
3 rotor.

BTW I notice that Motec has a CDI system for rotaries.

Motec uses the CAN bus and there are CAN bus to USB adapters
so you can use your tablet for engine parameters display (in theory) :)
