Hello all busy correcting mileage on a Land Rover Discovery 2 2005 (last one sold proberly) and opened the cluster and found L56R instead of 93c56 eeprom and I did some homework and the specs look exactly the same but I just want to varify with someone here that they are as the last thing I need this week is to ~~~~ up a cluster.OH and my UPA just arrived so can I give it ago in it as UPA only supports 93c56.Thanks in advance for your time and responce.
