    Has anyone fitted a Pertronix Ignitor module to an Euro '73 Dino?
    If so, can you tell me which model you used and if the control unit can fit in an empty Dinoplex box?

    Thanks in advance.

    You need Ignitor kit MR-161A. Everything fits within the distributor, there is no control unit.
    Simple :D

    The Ignitor I (MR-161A) delivers max 4 Amp coil current based on the manufacturer specs, which is not really sufficient for running a Dino engine, its basically the same as a points and coil setup.
    The Ignitor II (9MR-161A) should deliver a higher coil current but i haven't been able to find any output current specification on the manufacturer site. Need to source one these days and put it on the test bench to get a better idea.

    Both Ignitor setups are for the three lobe cam setup as in S125A/BX distributors, so you need to modify the supplied magnetic sleeve for your S125C distributor with six lobes and verify the phasing afterwards.

    Best,
    Adrian

    Adrian,

    A 6 lobe sleeve is available. If the Dino engine ran with points then an Ignitor will perform better irrespective of amperage. I have not heard of anyone complaining about the MR-161A. Of course, the Ignitor 2 will be even better, especially if teamed with a Flamethrower 2 coil.

    Mark,

    thanks for the update, do you have a part number for ordering the 6 lobe sleeve?

    Dino 206/246's were always supplied with a CDI ignition by Ferrari due to problems with the weaker points and coil setup. Fiat tried to sell their Dinos with a points and coil setup and then reverted to the same CDI ignition and also supplied CDI retrofit kits to their dealers.

    I had one installed for about half a year with a Bosch Red Coil/Resistor and had problems with spark plug fouling and overheating of the Ignitors IGBT which lead to misfires and a forced ref limit of around 3-4K until the unit had a chance to cool down. I know of two other Dinos and another Fiat Dino, which had similar problems and converted either back to a Dinoplex or to another third party.

    I am not saying that the Ignitor I is a bad product, it just depends on the engines requirements and the Ignitor I is not ideal for running a race engine derived Dino V6.

    That would be interesting, do you have more data like the avg/max coil current on the Ignitor 2? The website seems to have only high level information available.

    Cheers,
    Adrian

    Thanks.
    I'll call them. What data do you actually want to know about the Ignitor 2.

    Adrain,
    Ignore my query; I didn't read your post properly. I'll ask for avg/max coil current on the Ignitor 2 as you write.

    If I were to guess it would be 7 or 8amps

    Great, thanks! If they don't know that, the output in millijoule for the Ignitor/Flamethrower Coil setup would be interesting.

    Keep in mind that you also need a tacho adapter, if you plan to install an ignitor setup.

    Will do. Where does one get one of those?

    I was not aware that the Bosch Red coil is not compatible with the standard ignitor. It is a 1.5Ω coil, and has a resistance of 3.0-3.2Ω with the supplied resistor, as recommended on the Pertronix website for 6 cal setups/Ignitor I. BTW, the Flamethrower coil is very similar to the Bosch Red coil, most parameters are less than 10% apart including winding ratio and coil primary/secondary inductance.

    Yes, thank you! I'll add it to the market overview as 9MR-161A for the 3 lobe cam and MR-1121A3 for the 6 lobe magnetic trigger ring.

    Happy new year and best regards,
    Adrian

    Adrain,

    Here's the response from Pertronix regards my e-mail query to them on output:

    Ok, here are the readings. Please keep in mind any change to the Ignitor or
    coil will change the values. Also keep in mind this is a inductive system
    and not a CDI system. You can't compare the two based off these numbers.
    I2 @ ft2 @ 3000 120mj
    I@ft@3000 60mj

    I'm not good with electrics, does this make sense to you?

    Chris

    Yes it does, 60 mj as supplied by the Ignitor I is too low for the Dino engine from experience. The Ignitor II supplies 120 mj which looks good, should work fine when combined with EIX/EVX spark plugs.
