All my tests are on the car (Rover 214i (single injection) 95). I will try and get some more data today with the scope, DVM, but with a simple change to the code I am getting some more sensible figures for mpg.
I figure I need my timing to be started on a pulse less than 40uS, and stopped on a pulse longer than 400uS. But I need to see if the shutoff decay is constant at various rpm and loads, not easy by yourself!
