The Advantages of this 123-Ignition Conversions:
All Components are built into your existing distributor housing
16 Different Advance curve Settings
Smoother Engine Torque Curve
No points Maintenance
Variable Dwell Angle (to prevent low speed overheating of standard ignition coil and ensure a better spark at all speeds)
Suitable for Negative and Positive Earthed Systems
More Efficient Starting
Lower Emissions
Improved Fuel Consumption
Coil Power cut-off as soon as the engine stops (Prevents Coil Overheating) Spark Balancing
Spark Balancing is an advanced technology normally used in Formula 1 where engine speeds are tremendously high. This technique is used in the 123-Ignition System. Its microprocessor constantly monitors the amount of energy contributed by each individual cylinder.
Automatic Dwell Control
A mechanical distributor has a fixed dwell-angle, sometimes resulting in overheated coils at low speeds, weaker sparks and misfiring at high speeds. Why? An ignition coil only needs a couple of milliseconds to charge, but with a fixed dwell-angle these are "overcharged" many times when idling, resulting in… overheated coils! At high speeds the fixed dwell angle tends to leave too little time to fully charge the coil, resulting in… weaker sparks and misfiring!
The software also automatically adjusts the dwell angle (the time it takes for the coil to be charged) to the RPM. This also prevents the coil from getting overheated at low RPM. The necessity to adjust the T.D.C. remains (only once).
The ignition-system in a classic car is often the source of many problems. After years of use, the mechanical distributor becomes worn and increasingly inaccurate. Although replacement of the standard points with an optical eye or magnetic ignition set-up is an improvement, it does not compensate for the wear in the advance-mechanism, the distributor shaft and bearings within the distributor itself.
The 123-Ignition distributor is different.
The electronic components are built into your existing distributor housing, so it has the classic appearance to its mechanical counterpart. All electronics have been incorporated in the housing. New bronze bearings are built in to ensure no free play.
Maintenance Free Timing
In a 123-Ignition, all moving parts – like the original points, the centrifugal weights, the springs, the bearings and the vacuum-diaphragm – have been replaced with just one moving part: the central shaft with the rotor.
The internal electronics provide the right advance and the optimum dwell-angle throughout the rev. range to maintain peak energy and peak performance. There is no wear altering the timing of the 123-Ignition: once set, you’ll never have to worry about it again! Sixteen Advance Curves
Sixteen Advance Curves
With a little switch behind an opening in the bottom-face of the billet-housing, you can select the best advance-curve for your engine. Why? Well simply because many different advance-curves were prescribed by car-manufacturers. You buy one 123-Ignition, but you get sixteen different distributors!
