Joe,

 Here is an over view of the maximite. We also have a Maximite source
 code program for recording the compression on the rotary. The Mazda
 tool to do this is several hundred dollars.

 ----------------------------------------------------- Here is some
 experiments with the Ford V8 mass air flow sensor. I uses a small
 electric fan to simulate the air going into the engine. Worked like
 a charm. Of course it was idel air.

 Paul, So if we were to use one maximite for each rotor it would be
 possible to control the injectors for a two rotor. And I guess it
 could be set up to work with a MAP sensor instead of a MAF sensor.

 Is it possible to have the injector sequence end at say 80° before
 top dead center? Could this be shown in a chart form? Injector timing
 BTDC/pressure/RPM

 Could you also have chart showing the injector duty in cells for
 pressure versus RPM?

 Or would we need more maximite boards for each of these functions?
 Barry Bordes

 The Manifold Air Pressure sensor does not compensate for air
 temperature. The Mass Airflow Sensor does.

 One Maximite per rotor does it all. You fire the injector once per
 revolution.

 A very simple way of firing it at any crank angle is use another
 crank angle sensor. That removes a lot of software.

 I would inject into the next chamber when it came time to fire the
 plug in a given chamber.  The unique geometry of the wankel allows
 this. Super simple.

 A third Maximite could record everything once a second and display
 everything on the small LCD on the instrument panel.

Paul,

What fires the ignition?

I looked at the M&W site and there are T1, t2, l1,and L2.

Joe Berki

 Those are the Leading and Trailing coils.

Four total. One for each plug.

Simple.


Joe,

This is the conversation I had with M&W sales.
I was unable to find out how to trigger the system with or with out a computer.
Apparently I was talking to a non engineer.

I think it will work but you will have to buy one and experiment with it to find out.
A pulse is a pulse whether it comes from a computer or a conditioned CAS.

They make some good stuff in Oz but the documentation sucks.

Maybe somebody else on here that speaks Oz can try :-)

I give up.

Wayne, are you an engineer or electronic technician
or are you just sales? Do you know what a CAS is?
If not show this message to the engineer.

Suppose I fired L1 and T1 with the same leading edge  pulse from the stock CAS (crank angel sensor)
at 22 degrees BTDC and used another CAS  180 degrees out to fire L2 and T2 would
that work with the  rotary ignition _Pro-14R <http://www.mwignitions.com/pdf/Rotary%20S3%20instructions.pdf ?_

What would I have to connect pin 5 to.

Paul

Please explain exactly what you need.


Wayne

so we would need 4 for a rotary. One for each coil. That does not sound like
the lowest cost solution.

Suppose I fired L1 and T1 with the same leading edge  pulse from the stock CAS (crank angel sensor)
at 22 degrees BTDC and used another CAS  180 degrees out to fire L2 and T2 would

 Our single channel Pro-10R already has a reluctor interface built in
 and we will be releasing an adjustable rev-limiter version of it
 shortly.

 Wayne



 do you have a single channel system?

 we find that a fixed 22 degrees BTDC works fine for us.

 No variable advance.

 We use a LM1815 conditioning IC The pdf is attached.

 It works with a CAS set to 22 degrees BTDC

 The multi channel systems are designed fro triggering from an ECU
 not crank trigger.


 Wayne


 how do you get your ignition to work with a carburetor? Is is
 suffacnt to trigger pin 5 with a crank angles sensor?

 If so what do I do with pins 25, 27, 28 and 29?
