Fiat Dino Forum (FDF)

I wonder why he said that the restriction works a bit slow, usually a current restriction limits the current as soon as the maximum peak is reached (within fractions of a millisecond), avoiding any overshoots. In a high performance inductive ignition you try to use a very low resistance so the maxim...

Hmm, the 123 PCB i know has a STGB20NB37LZ IGBT in place, that one can handle 40A at 25ºC and 20A at 100º, pulsed 80A. A 0.8Ω could would be run at a max of 6-8A to avoid running it into saturation, so the IGBT should have no problem driving it even continuously. For the MSD 6A please use the Blaste...

Yes, but you could also connect the 123 to your Dinoplex with the same result (output, tacho). If 123 can drive the Bosch 334 coil you would need even less hardware. P.s. MSD and Dinoplex do not require dwell control as they are capacitive ignitions. Dwell is only required by inductive (coil charged...

The primary resistance of Bosch 0 221 119 334 is 0.8Ω. The lower the resistance = the faster the coil charges so you have more energy available at high RPMs. Keep in mind that the Bosch red coil is specified for points and coil setups where it has to be used with the external ballast resistor (1.8Ω)...

Adrian, that makes sense. The guy producing the 123 ignitions lives around the block for me so i'll might discuss with him what is possible and what not. If i understand you correctly the downside of this ignition is the maximum current output from the coil in combination with what the circuit boar...

p.s. you can remove some of the problems with the weak output of the Bosch red coil by using NGK BPR7EIX spark plugs, they lower the secondary voltage required to create a spark due to the fine tip design.

You could try a 100K potentiometer for finding the best resistance as long as you don't go below 5K to avoid too much load on the Zener. I would just try a 10K, 33K, 47K or 68K resistor and keep the one which works best. The problem with the 123 is the maximum specified "coil current", whi...

The electronic Veglia tach expects a square wave 12V signal, as coming from the distributor in a Dinoplex factory setup, it won't work with a high voltage pulse when connected to a coil minus terminal. What you could try as a work around is to put a 10K-47K resistor in-between the tacho wire and the...

Keep in mind that with the Red Top you need a pressure regulator. The Facet is also quite loud, you have been warned
