Will the Maximite be able to monitor and change the fuel/air ratio via
the o2 sensor.
Regards Andrew Campbell.

Yes but be aware 100LL aviation fuel kills O2 sensors. I would not use
that as the only sensor to set the mixture. I would still have a MAP
or Mass Airflow Sensor. I would also use the wide band variety and place it
at the end of the exhaust pipe. Aviation rotaries run hotter exhaust as
they are on average a higher percentage of max power.

Paul,
Thanks for the information, I know very little about rotary engines apart from what I have learnt from your emails and your books.
Some time ago you suggested that some people have had a certain amount of success with fuel injection before the turbo, do you have any contacts that I might be able to use to obtain some further info on how the set up is working?
Regards Andrew Campbell


It is common practice with carbs so it should work with fuel
injection. If you can't find one injector large enough you
can use several. It is a good idea anyway as one injector can fail.

I don't personally know anybody doing it that way.
