I have just bought a 1972 2000 TC, which I will pick up tomorrow. I assume it has the 10:1 compression ratio and originally ran on 5-star fuel. What do people use nowadays? Super unleaded? Super unleaded with octane booster? Ordinary unleaded with more octane booster?
I guess the ignition timing could be retarded to suit today's lower-octane fuels, but I'd very much prefer not to do that because it would kill the performnce. Has anyone tried mappable ignition to get the best power from today's fuels without pinking? I'm wondering if a programmable 123 distributor, or an Aldon Ignitor II electronic ignition module with an Aldon Amethyst mappable add-on, would do the trick.
All advice gratefully received!
