Hi Guys,
I have just purchased a new MPVI2 and am ready to start learning the A45 MED17.7.2 ECU. I have previously tuned LS2 V8s on the older interface.
I would like to read my ECM and get familar with the layout and tables available however when i try to read I get prompted to write a software update to the MED40AMG ECM to enable tuning.
My car already has an existing tune installed by a 3rd party tuner. If I do the ECM software update is it likely to cause issues for the car or the existing non standard tune?
Thanks
