BMW F series EDC17C56 has GPT lines. It is not possible with Kess v2. Which tool will do and is there some other scheme to follow?
Tools that can read/write EDC17C56:
KTag genuine read this perfectly. Ktag 7.020 clone works like a charm with GPT cable.
Done on 320d (US “328d”, with EURO6 components), GPT boot mode works correctly on china clone. My tune works very well too. I have done multiple flashes during testing and tuning. A little slow, that’s all. Enough time to grab a coffee.
Today I managed to complete the reading of this ecu to be able to read it I had to use the following pinout:
boot mode cable with cables follow this list
pin 1/18 red cable + 12V
PIN 02 GND black earth cable
PIN 56 CAN H white cable
PIN 55 CAN L green cable
Gray cable crocodile clip boot point marked by ksuite
In the bdm / jtag slot insert gpt cable and insert orange cable pin 89
pin 92 yellow cable
If you receive a communication error with the control unit try to put the gpt on the mainboard.
