Paul,
Here's a little bit of information that I was unaware of before.

It would appear that aftermarket ECU's don't support the electronic oil metering pump of Series 5 and later
The only way to get around this is to put in the Series 4 manual pump with an aftermarket ECU like Microtec.

This was one of the reasons I never purchased the RX8 engine advertised locally as I was concerned ( at the time) more about an aftermarket ECU managing  the complexities of the inlet manifold of
the air jet atomiser . The oil metering pump is another similar problem.

I don't know if Tracy has looked at this in his latest edition ECU - if he has I would like to hear about it. I also wonder how he manages the management of the inlet of his RX8 engine.

Tracy mixes the 2 cycle oil with the fuel as do the majority of people putting
rotaries in airplane. The metering system is just more parts to fail. Particularly
the stepper motor metering pumps. Not only that they are very expansive running $1500
new.

Tracy uses a fixed tuned home made system in his RX8 engine. He does not use the
stock intake system.
