Some experiments back in the day. Also Jim Toensing had some kind of FI setup on his GT40, I don't know whether it was TJ or Hilborn. This would be very difficult to drive on the street; these were basically race systems. When 103 was sold to Symbolic Motor Car Company, it had a Ford Indy DOHC engine fitted with EFI which Bill had adapted to it; it had coil pack ignition and an ECU-regulated system on it. It WAS street drivable but by then the technology had moved along considerably, with computers to run the FI system and coordinate it with ignition.
