Dave Leonard There have been various numbers bandied about on the current requirements to run the engine, but I go back through my notes and find I don't have any firm idea. Too much inconsistency. It would be nice to know for each item - injectors, coils, pump, etc.; but I'd be happy to have a measured total current draw to run the engine: 1 of Tracy's fuel pumps, all the injectors, all the LS1 coils, and the EC-2. Anybody operational with an ammeter that could turn everything else off, battery charged, run at high rpm - like 5000-6000, and measure the current? Nothing in Tracy's write-up on the EC-2 except that he uses a 50A breaker on the engine critical bus. I would hope the steady value is about a third of that; or less.
