Don't forget that the fuel flo xducer has a sensor count specific to that unit and will vary between units. The K factor must be entered into any engine monitor to account for this variance. Most have a place to enter the K factor, but I think you either need a range of K factor or have it burnt to the eeprom for the VM 1000.
Good luck.
