Has anyone driven an Autometer Tach with the 0411 ECU (pin R10)? I am also using it for the Aeromotive Fuel Controller - but Aeromotive says the output signal is 5v and it needs a pull-up resistor to 12v - I've done that and the fuel controller works correctly and since the tach needs a 12v signal I'm using it for that also - but the tach doesn't work. Any ideas? -Bob
