Actually, we were doing some R&D for a new ignition system, for a manufacturer out of Iowa. He didn't come out and call it "traction" control, but you could say it was, however, it was a manual system, with 4 advance curves built in, and programable, however, you controlled it with 2 toggle switches, and it did have some effect on wheel spin, we ran it most of the season, and at the time, it was RPM limited, by a fault in the encoder wheel, which he later fixed, but I can't bring myself to try it again. Maybe someday. Bob
