Default Digital mileage correction.

Has anyone used one of these businesses who advertise digital mileage corretion? And if so what did it cost?

I am going to be replacing the instument cluster on my 45 with another used one,and would like to preserve the correct mileage from the original.

Hi Andy

Nick at Austin Garages tells me its a different system on the 45.He had originally hoped to physically transfer the mileage unit fom one cluster to another but on investigation on another unit found it not possible.

You need to dump the 93c46 eeprom. alter its contents (stored mileage reading) and reprogram it.

Or simply swap one to the other, depending on what was wrong with the original speedometer
