 I am the person who designed all the cdi ignitions on our website,
 unfortunately i'm not good at reading minds.

 The messages received here are incoherent and difficult to
 understand also please keep in mind that terminology and acronyms
 vary from country to country so its best to keep descriptions basic.

 I designed the Pro-14R to be capable of firing two outputs
 simultaneously or with any split desired.

 If you only have two triggers and want to fire both channels at the
 same time you can pair up a leading and trailing trigger.

 Our systems are normally triggered by an ecu which provides timing
 adjustment however if fixed timing is all you need then the unit can
 be triggered with a hall effect sensor.

 I am out of the office and only have have access to the documents on
 our website.  Each instruction manual has both schematics and pin
 description.

 I have one of your rotary ignitions working on a 650 HP two rotor. It
 started missing at high RPM so we assumed it was a voltage supply
 problem. At 8000 RPM what is the lowest supply voltage that will
 work. The spark plug gaps are .025" The ignition is controlled by a
 Motec 800.

 It has no alternator or voltage regulator so we are installing an 18
 volt battery.


 The rotary fires once per rev on each rotor.

 On a two rotor the firings are 180 degrees out.

 Each rotor has two spark plugs. There are 4 spark plugs total.

 The spark plugs on one rotor can be fired at the same time or they
 can be fired several degrees apart.

 Is that clear?

 I assume that L1  in your pro14R rotary ignition  documentation
 instructions stands for the leading spark coil on rotor 1? T1 is the
 trailing spark coil? It does not say that in your documentation. It
 just says "trigger" what every that means. "Trigger" is a very
 general term. If it is a coil what are specs for the pulse?

 Is that spelled out in the istallation guide?

 Read istallation guide for important wiring details!

 Can I get a copy of that guide?

You talk about a Pro-14R however you image you included is for a Pro-Drag4R, similar function but completely different installation instructions  and power level.

The unit was supplied with an installation guide, if you have lost it a copy may be downloaded from our website under the support -Technical Documentation tab.  Check the bottom sticker on the box before downloading as we have both Series 3 and Series 4 versions.

Triggering is explained in the documentation along with trigger edge and a great deal of important details for achieving a successful installation. They also list operating voltage and warnings about the use of 18v battery systems.

As these units are specifically designed for rotary engines L1 means Leading 1 and T1 means Trailing1 etc.

Did the installation run ok initially with our system installed and then start misfiring or did the problem start as soon as you installed the new ignition?

I have both the drag and the regular version. The Pro14R and the pro14R Drag
docs.

What is the exact part number for the "installation guide"

I don't see anything named "installation guide" on your web site.

The M&W ignition worked OK at the lower RPM's. He probably ran the battery down a bit
and then he tried a full power run which means up to 8000 RPM.
It is connected to a Motec 800. It was installed by some one else.
He died and did not give us any documentation.

A lead acid battery will lower it's voltage when more current is needed.
As you go up in RPM with a CD system current requirements increase.

We are now installing an 18 volt battery.

Since I am very familiar with CD ignitions having a patent pending on one
of my designs I know that the high voltage (300 volts) required to charge the capacitor
is very sensitive to primary battery voltage at less than 12 volts.

Here is a video of my system
at 8000 RPM. This is 4 sparks 5 degrees apart. Patent pending. It will be  a revolution in ignition
systems if I get the patent.

This is not to criticize, degrade or compete with your systems.
Your system works fine with the right battery supply voltage for one spark.
I like it as potentially it will work with out a ECU if I can only figure how
to wire it :-) In other words a carburetor-ed engine.

My next door neighbor manufactures and sells CD systems that work down
to 5 volts but the design engineer set out to do that when he designed the high
voltage capacitor charging supply. His works with carbs.

It is called Light Speed Engineering ignition. His only works to 2600 RPM
for up to six cylinders.
