This reminds me of a story told by Mike Valentine (of Valentine radar-detector fame) about having to drive home from work near Cincinnati, across the path of the Voice of America WLW AM transmitter. The 500,000watt VOA signal would make the Bosch D-Jetronic fuel system in his Porsche reset itself; the car would stall and you had to be going a certain speed before you intersected the beam so you could coast through and then restart the engine once clear. The D-Jetronic isn't really microprocessor-controlled though; a similar story came from the Missouri Highway Patrol. In the 1980s, they had pursuit 5.0L Ford Mustangs, with Ford EEC-IV MCU fuel injection. They also had police radios that had been tweaked to increase the transmitting power past what the FCC would consider normal, and past what Ford had rated the EEC unit for EMF. It was discovered that, at highway speeds with the cruise-control on, holding the transmit button on the handset down for more than ten seconds caused: 1.) The engine controller to think the gas pedal had been floored. 2.) The transmission to need to downshift. With the police-duty 5.0, this was...startling.
