Co-founder here. Do the cars you're talking about use a distributor? The battery of a car works as a low pass filter for the alternator, and removing it entirely can cause huge spikes in the voltage it puts out. That can be destructive to just about any electronics it would be running. I've personally seen an accidental battery disconnect blow an ECU.

- userbinator 11y agoThe grandparent poster could be talking about magneto or traditional points-based ignitions, which are still common in certain classes of racing cars.
