Thread: Question about Using Streetfire CD Ignition with a Ford TFI Distributor.

  1. #1

    Default Question about Using Streetfire CD Ignition with a Ford TFI Distributor.

    So I currently have a 5.0L Mustang engine running with a MSD 2 Wire Distributor, Streetfire CDI and a Holley Carb.

    I will me moving it to a Speeduino EFI Controller in the spring and am considering using a Ford TFI Dist With out the TFI Module. That leaves the Distributor acting exactly like the MSD Dist two wire unit - to my understanding.

    I like this combination since the Ford Dist has a Smaller Tooth for #1 Cyl and that allows for sequential Injection in the future. In addition the Ford Dist already has Locked down Ignition advance which the Speeduino requires for precise ignition control.

    Anyone on here used this combination or know of a reason why it would not work?

    That would not work on the TFI with the module removed due to the fact that the distributor pickup on the inside isn't a magnetic pickup, it is a hall effect pickup and the signal wont tell our box to fire. However, if your EFI will accept the signal you may be able to make it work if it accepts it, then through the EFI it would send a signal to the MSD box to tell it to fire at that point. So, you may want to check into that.
