FuelMaster Plus FMU 3500 Fuel Management System - Please Read

Description

Fuelmaster Plus FMU 3500 fuel management system.  I don't think it's ever been used but it has been tinkered with.  Case has a few small scratches and scuffs, and lock has been removed.  One board marked Pulser Board does not seem to have a place to attach.  Includes two "Prokee's".  On power-up, it notes "no compact flash detected" and "AIM2 system not detected", and seems to indicate that the software installed is FMU 2500+.  When the Prokee is inserted, it asks for a User ID, which I do NOT have, so that's as far as I could test it.  Sold as-is, as described, no returns.
