Good to know: do you have the RH850 / V850 Full kit? It already contains ECM-001, TCM-030, M002, TCM-MAIN + Converter V2 and MQB Collector. The M037 is already supplied with the MotoMaster and with the A2 motorcycle cables option of the Key Master G3. On the DC706, ECUs marked MP001 in the OBDSTAR list require the MP001 programmer in addition to the cable.

Professional and lawful use only. Cluster calibration is for transferring the real mileage after an instrument cluster is replaced or repaired. Altering a mileage reading to deceive a buyer is a criminal offence in every European Union country.

❓ Frequently asked questions

How do I know if my ECU has a dedicated cable?

The OBDSTAR compatibility list shows the dedicated cable for each ECU (“Dedicated” column). Tell us the reference and your tool: we will answer.

With the DC706, do I also need the MP001?

For the ECM-001, the ECM-003 and the C4-09, yes: the OBDSTAR list requires the MP001 programmer (or a P003 / P003+ for some ECUs). The TCM-030 works with the P004 adapter supplied with the DC706. The Key Master G3 already has the MP001.
