Both Digijet and Digifant are implementations of Bosch's L-Jetronic system. For more information on them, I found "Bosch Fuel Injection Systems" (ISBN 1-55788-365-3, published by HPBooks) very helpful. You wouldn't get a pulse if you unplugged the hall sender because the ECU doesn't think that the engine's running. You will with the AFM unplugged because the ECU knows that it's running, but the amount of the pulse will be GROSSLY inadequate for what the engine needs. By far, the AFM is the more important input for making the engine run reliably and stably -- but you won't get anything without the hall input. -Kyle On Wed, 1 Sep 2004 19:53:35 -0400, tabe johnson <xtabe@yahoo.com> wrote: > Does anyone know how Digifant works?
