Mr. GDE,

Can you tell me if there would be any issue programming a 56044776AD - base release ECU for my '06 CRD?

Reason for asking is I could be able to get my hand on such ECU but found, through research, the following:


56044776AD - base release
56044776AE - improved start ability
56044776AF - lower torque output to protect TC
56044776BA - lower power to glow plugs to reduce potential for overheating
56044776BB - change to FCV to reduce potential of failures

For the owners of '06 CRDs we would highly recommend verifying you are running with an ECU part number suffix of BA or BB

Does the GDE tune automatically update a base release?

The main reason to have the latest part number release is to prevent a dealer from reflashing the ECU and erasing the tune when in for service as many will routinely check for TSB updates and flash vehicle as standard practice. Since you are using this as a second ECU for tune only, there is no negative associated with the older part numbers. The tune will perform the same and we inlcude all of the good aspects within the TSB updates and leave out any unecessary changes.

Go ahead with the ECU purchase if it is going to be dedicated for tuning.
