The 123/FIAT-2R is designed especially for Fiat 500- and Fiat 126-engines. It comes as a complete distributor. Just like the 123/FIAT, it will do away with wear: no more replacement of points or capacitor EVER again. The advance is now electronically calculated: set it, and forget it!
WHAT’S NEW ABOUT IT?
All other systems of electronic ignition for FIAT require that the original mechanical centrifugal advance system is still fitted, points assisted systems 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.
This construction of all the electronics inside an almost original distributor 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 the 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?
A typical ‘FIAT-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.
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 better spark at all speeds
– Better starting
– Better emissions
– Better fuel consumption
– 16 different advance-curves, ideal for tuning purposes
– 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 your money!
Use aluminium ring on a 500cc (110F) engine! Don’t use the aluminium ring on a 600/650cc (126) engine! Please read the installation manual carefully. It contains more information about the motor- and distributor numbers, static timing and the advance-curves (often found on the last page), the specifications of the 123-ignition and a step-by-step description of the installation procedure.
