I understand the B20E/F computer can be modified to allow for adjustable
fuel richness from a dash mounted potentiometer. Does any one have the
wiring diagram of how to modify the computer circuit board and what value
components are required? syd

a 1000- 4000 ohm potentiometer (volume switch) in series w/ coolant temp sensor works fine. I can look up pin #'s if you want.

If you go to Radio Shack to buy the potentiometer, be sure you get a linear taper, not an audio or log taper pot.
I used a 10k on my '73 ES.
