I am trying to help a friend with his 93 FD her in Denmark. We went for a drive and I opened the setting function. We discovered his injector pulse timing correction, boost settings, acceleration enrichment setting and rpm settings all show Zero? When I select a parameter and add a value, then exit and return to the selection... it remains Zero again? Disconnected the battery and I installed my commander and had the same result. Never seen this before, monitor display and the rest of the setting modes all work fine.... any advice would be helpful.

Regards
Oliver
