123ignition, fantastic distributors for fantastic classic cars

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 123ignition distributor is different. It comes in its own aluminium billet and nickel plated housing, although externally similar in its classic appearance to its mechanical counterpart, it contains high-tech electronics on the inside. While maintaining classic appearances under the bonnet, the internal technology makes your ignitionsystem and engine perform better than ever before, and run as smoothly and reliably as a German sewing-machine!

Maintenance free timing

In a 123ignition, 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 123ignition: once set, you’ll never have to worry about it again!

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 123ignition, but you get sixteen different distributors!

Spark balancing

Spark Balancing is an advanced technology normally used in Formula 1, where engine speeds are tremendously high. This technique is built into the 123ignition. Its microprocessor constantly monitors the amount of energy contributed by each individual cylinder. Assume for example that the compression of one cylinder differs from the others. The motion of the flywheel would be less smooth, and so is the motion of the camshaft. The 123ignition detects this, and adjusts the timing of each cylinder individually. This results in a much quieter engine, more power and less wear.

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 “ over-charged” many times when idling, resulting in…. overheated coils! At high speeds the fixed dwell-angle tends to leave to little time to fully charge the coil, resulting in .. weaker sparks and misfiring!

The 123ignition measures the amount of current flowing into the coil, in such a way that the strongest possible spark is guaranteed at all engine-speeds, whilst keeping the coil cool.

Also to prevent coil overheating, the power to the coil is cut-off as soon as the engine stops.  

What are the most important advantages of the 123 ignition system?

·         Simple installation without mechanical adaptations.

·         Smoother engine torque curve.

·         No maintenance – ever again!

·         Variable dwell angle to prevent low speed overheating of ignition coil and make a better spark at all speeds.

·         Better starting.

·         Better emissions.

·         Better fuel consumption.

·         No burning out of the ignition coil (after stopping the

·         engine power is cut to the coil after 1 second!).

·         Built in LED for simple static ignition timing.

·         Real value for money.

123ignition for the Aircooled Volkswagen engines, 123\VW-R-V

The 123\VW-R-V is created in cooperation with VolksRepairs, the Aircooled Professionals in the Netherlands; this has resulted in a product that can be used in all type '1', '2' and '3' cars, AND that can be used for Porsche 356 and Porsche 912.

The unit comes standard with vacuum-advance, but is also available without. ( 123\VW-R )

The installation instructions show a cross-reference between the original Bosch-number and the setting of the 123\VW-R-V.

There is also a list, that links VW-engine-numbers with the required setting of the 123ignition.

Specifications

Prices

The 123ignition without vacuum-advance (#123\VW-R) costs: € 239,-- including VAT, and the 123ignition with vacuum-advance (#123\VW-R-V) costs: € 299,-- including VAT, all prices shipping not included.
