Just a week after the release of the latest update, we present to your attention an indispensable innovation for chip tuning BMW and Mini.
We decided one of the most important problems — the problem of CVN and a Counter.
"CVN” ("Calibration Verification Number") is the checksum of the calibration file recorded inside the control unit. CVN control-the method by which the calibration in the control unit is checked to see if it matches the one chosen by the vehicle manufacturer. Thanks to the new protocols 628 and 629 For the kessv2 tool, when writing a modified file, CVN will match the original firmware ECU.
“Counter” is the counter programming of control units, Bosch EDC17 and MED17. It indicates the number of modifications the ECU has been subjected to. In this case, due to protocols 628 and 629, this programming counter will not be increased.
The CVN and Counter will be displayed in the Protocol ID in the software version field.
With this update you can work on the control UNIT BMW F-series, through the diagnostic connector OBD, both diesel and petrol versions.
No need to open the unit! You need a tool with KESSv2 OBD standard cable to intervene in the tuning of BMW and Mini, which are equipped with the following ECU's:
