for 2CV4, 2CV6, DYANE, AMI, Mehari
|The '123\2CV' is designed for all 2CV's ( and derivatives ) with a A79/1, M28 or M28/1 engine. |
It is a microprocessor controlled device, that replaces all the mechanical parts of the conventional system, like points, cam, and centrifugal weights.
The 123\2CV is designed for the stock ( black! ) coil, and is intended for 12 Volt systems only.
The ease of installation, and the outstanding quality has attracted thousands of happy 2CV-drivers, all over the world.
The main benefits are :
- better starting
- better fuel consumption
- smoother running, better emissions
- more torque ( especially in the lower rev's )
- no maintenance, EVER again

An ignition system so advanced yet so simple that all 2cvs should have it!
WHAT’S NEW ABOUT IT?
All other systems of electronic ignition for 2CV (Lumenition, Newtronic & Multic) require that the original mechanical centrifugal advance system is still fitted, points – assisted systems (Boyer – Bransden etc.) even use the original points operating cam which suffers uneven wear and consequent lumpy running of the engine because each cylinder has its own inaccurate ignition timing. Furthermore they all require a separate box for the associated electronics.
’123ignition’ is different, all is contained in one simple module which just goes in place of the original points box, the points operating cam is removed along with the advance weights and their bearings which wear, two strong, small magnets slip onto the drive pins which previously held the advance weights, ‘123ignition’ is then simply bolted on.
AND YET STILL MORE.........!
The construction of all the electronics within the original housing where the points box would have been means that there are no unusual wires and connectors leading to a ‘box of tricks’ (other types of electronic ignition have that) which has to be mounted somewhere!
So much better than a conventional contact breaker set up because the variable dwell angle ensures a large spark at high engine revolutions, with ‘points’ and of course points assisted ‘electronic ignition’ the dwell angle, controlled by the points gap, remains constant so at high revolutions the coil has insufficient charging time. 123ignition addresses the problem of dwell angle in just our basic model – other makes demand that you buy the ‘sports’ version for such performance!
SMOOTHER ENGINE, MORE BALANCED
So how can 123ignition make an engine smoother? Read on....
A typical ‘2CV problem’ is the slightly different ignition timing obtained on each cylinder because of wear or irregularities on the contact breaker cam, 123ignition properly addresses this problem in 2 ways, firstly the cam is removed and secondly that even if the two magnets were not evenly spaced the software within 123ignition converts it into perfect timing.
NO MOVING PARTS
Additionally, because the ‘centrifugal’ advance is now handled by complex software (all within the one simple module) acceleration is unbelievably smooth but particularly so in slow running in traffic,(from 1000rpm to 3000rpm) this is far better than with conventional ignition where the weights are constantly adjusting in traffic – with any wear in the bearings the advance curve is not even.
THE ADVANTAGES SUMMARIZED :
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 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.
