Chuck Dunlap told me a funny story today. He is dune buggy fan
and he has a VW powered buggy with a Megasquirt EFI system on
it. On of the injectors transistor drivers failed when he was
ten miles from nowhere out in the Glammis dunes.
There was nobody around powerful enough to tow him home so he
disconnected the lower contact on the injector from the failed
driver transistor  and used a jumper wire back to the cockpit.
He was able to keep the engine running while
grounding the injector wire periodically with a free hand. Now that is
what I call keeping the pilot in the feed back loop.
Pilot controlled PWM :)
