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

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.

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.

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
sufficient to trigger pin 5 with a crank angles sensor?

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

GEEZ, some sample hook up drawings would be nice !

Is this helpful?

I have that document. It says "trigger". When I see that I think of my gun :-) Trigger what? A trigger in electronics
can be in or out.  Is it in or out? What do I wire it to? The crank angle sensor? The ECU or is it an output to the
coil? It is not specific! In the M&W documentation. There is a symbol wired to it  but it is not identified.

The other term they use in this document is "total loss electrical system" what the heck is that?
Translation of Oz English to U.S. English is a "electrical system with out an alternator or voltage regulator".

I have only been working on cars for seventy years. Yes seventy years as I started working
on dirt track racing cars when I was eleven years old in 1946. I never heard that term before.
Perhaps it is a term from drag racing but not every body is a drag racer.
