I forgot to mention, the GM/EBL system also integrates the ignition control (ESC) system using an Olds ESC HEI distributor from a mid '80's 307.
EFI makes the engine start and run like a modern engine, but ESC really wakes it up!
If you elect no to go with ESC from the start, you need a small circuit board that reduces the 12V pulses from the distributor TACH output down to 5V pulses. Howell came with this circuit in the wiring harness, but I'm not sure about how Affordable EFI handles this. The google group can help if you need this.
Don't worry about all the tuning capabilities, there are downloadable files on the Google group. They are very easy to flash into the EBL if not preloaded. If you want to get into the meat of the system, the EBL makes that easy as well. Or you can just let it do its thing, no worries.
Since you a higher pressure electric fuel pump for EFI, many of us have gone to dual pumps at the tanks. This eliminates the tank selector valve and gives redundancy with a second fuel pump.
