The Motec M4 pictured below was bought new many years ago for a project that didn't proceed. It's been sitting in a box complete with a new loom and sensors ever since. Going by the serial number ( in the 800's ) it must be quite an early M4.
Is there any reason why this unit shouldn't still work and can it be upgraded to last version of the firmware? Is there anyway I can get the unit to perform a basic self test before I go down the path of trying to install it?
Thanks in advance.
