Adding timing to my ITB install

[KMoore68]

Hi,

I have a fuel-only installation of EFI and Triumph ITBs on my 1977 911 S Targa.

This fall I am planning on adding timing control to my installation and was hoping to confirm what I need to purchase. I have confirmed my ECU has the supporting mods to control the timing.

I am planning on replacing the 3 point CDI in my car with MSD Streetfire and replacing the points in my distributor with Pertronix Ignitor. I believe I need to wire a 1 kohm resistor between the 12v supply to the ignitor and the signal wire to the Pertronix ignitor.

I currently have the stock Bosch black coil and stock plug wires with grounds, do I need to replace the coil, plug wires and new plugs?

Thoughts?

Thanks,
Kevin

Hi Kevin,

I’m not even close to an expert, but how would the ECU control advance and retard on the setup you’re proposing.
