Road Relay 4 on 2001-2002 Trucks

[GScott]

Tried a Road Relay 4 on a 2001-2002 Dodge ISB? Dont! I installed one and noticed immediately that the fueling data is blank, the rpm reading is intermittent, oil temp is missing, and cooling data rolls to zero over 204 farenheit. Cummins sent me an e-mail saying they know about all this and that they are working on revised software to work with the 2001-2002 trucks.

Thanks for the heads-up.
