Paul,  Further to the stats. of Aust engine failures, It appears that the failures are mostly spark and not fuel although both need a power supply.  It is suggested that between all the requirements for spark,  Cranks angle sensor, ECU to control, either trigger box or smart coils, wiring to everything plus a bullet proof power supply and the inevitable electronic failure, hence the current problem. Since none of the ECU manufacturers microtech and motech are interested at this stage in altering their firing to accommodate your multifire, I am trying to get redundancy into the present system.  I am suggesting leaving the current system in place which will get the ECU to tell me what advance it is using, which it does, while actually controlling the engine.  Then if your system is also installed that can be either the main or backup system.  Coils are the same, but I now have the standard ECU spark control,  (and yours in standby) or it can be reversed with yours the main with the standard ECU as backup.  Not entirely sure this will work, so that is now my question. Will it work and how difficult to get to work? Fuel failure seems to be way down the panic list, whereas ignition is top of the list.  AS stupid as usual,

Neil.

My system has the coils built in. It can not use off the shelf coils as used
by Microtech and Tracy's system. Smart coils or otherwise.
This means you have only one set of spark plug wires.

It is a complete stand alone ignition system. One system
per spark plug. Four complete ignition systems. Highly redundant.

I am testing them for hours at 10,000 RPM and 6 sparks.
The temperature of the box stays below 100 F.
It is very efficient.

A mechanical failure of an electronic part is not possible as they are
embedded in solid potting compound.
