Multi-line 2 GC-1F Application Software series 1.x.

This software applies to the following DEIF products:

You’re about to download 1.24.5

The main changes implemented since the last version are as follows:

This software applies to the following DEIF products:

  • GC-1F v.1.xx
  • EIC: Modbus readings and displaying of a few EIC data: Coolant temperature, Fuel temperature and Charge Air Temperature where presented with different number of decimals depending on the engine protocol selected. This has now been aligned so data is presented in the same manner independent of engine protocol selected.
  • IC: FMI texts updated to meet J1939 specification.
