As we all know, vxdiag vcx se is a good passthru j2534 device. Possible to use it with pcmflash?
MBCoding has tested the vxdiag vcx se benz (as well as other vcx se series) as a good pcmflash passthru j2534 device.
Here is the demo example on how to flash the Mercedes S500 W221 with M273 engine ECU ME97 using PCM Flasher and vxdiag vcx se j2534. So you can make a chip tuning yourself, Stage 1, Euro2.
Make sure you set the power supply to 13.5V.
