i read this thread bro .. but is there another way ??

No the signal does not exist on the OBD II connector anymore. All signals from the DME are now on the CAN network. So you will need a CAN compatible device to get signals from the CAN network.

If your device can not read CAN then it can't get your information.

Networking/data communication

Electronic networking in the 911 Carrera allows data and electrical information to be exchanged between various control units throughout the vehicle. This is realised with the aid of the internal high-speed network, the so-called CAN-BUS (Controller Area Network), and the fibre-optic network, the so-called MOST-BUS (Media Oriented System Transport).

In the 911 Carrera, up to 29 control units can be exchanging up to 2 MB of data per minute via the CAN bus at any time. Approx. 2,500 different signals have been defined to this end. Networking reduces the number of connections required so that the total length of cabling required can be kept significantly shorter.

Most of the network connections can be found in the following areas:

• In the area of engine management for high-speed information exchange.

• In the area of coordination of networked control engineering. Thus a PSM braking operation, for example, involves the control units for the brakes ( PSM), engine, tyre pressure monitoring system and Tiptronic S.

• In the area of audio/communication for the joint transmission of digital audio and control data via the MOST-BUS.

• The use of network connections has enabled a reduction in weight of approx. 5 kg in the new 911 Carrera, even though functionality has been extended.
