Bosch now makes a new ECU for the cummins that is totally programable. Cost a little for the ECM but the software is free from bosch. You also have to buy a hand held for another $500.00 to be able to connect to the lap top. They claim it to be much better than EFIlive. I got a demo and thought I may not be ready. I'll leave it for the shops for now. For more info:
