What type of distributor do you need to control ignition timing using FiTech?
I know there's a bit of confusion out there about what type of distributor can be used with FiTech Go EFI Self-Tuning Fuel Injection Systems.
If you ask FiTech tech support, they'll be a little vague and mention any 12v, 2-wire, magnetic pickup, rotor phasable distributor should work.
Here I'll walk through the distributor I used (MSD Street Fire part number: 5591) and how I set it up to make sure I'd be able to take advantage of the FiTech ECU timing control functionality.
The rotor on this distributor is prephased but I had to remove the ignition control module by removing a couple of screws and wiping off the thermal grease.
After that I clipped off the connector coming from the distributor magnetic trigger and crimped on a female spade connector to connect to the spades on (MSD GM HEI Module Bypass Cable part number: 8861).
With everything completed I stabbed in the distributor and brought the engine to #1 TDC on the compression stroke and stopped at my base timing. The base for my cam is 10 degrees.
On the controller keypad I typed in this number under "Ignition Setup - Distributor Base Timing".
After cranking over the engine and using a timing light I matched the reported timing from the controller display to what I know I set my timing at.
From there the FiTech was able to control timing.
