An interesting episode of an older Wheeler Dealers program demonstrated the advantage of switching to Electronic Ignition from Points on a XJ Jaguar. The Spark intensity was improved by a factor of three. Plus a wider plug gap as a bonus.I had a particularly good result on my MGA years ago. with a new Distributor, which had an improved Advance Curve to suit modern Fuels. Back when the Car was new, the Octane rating would have been around 72.
