Top Tools to Read BMW EDC17C56 ECU

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:

1). Ktag

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.

and check the cable too for the GPT ones again.

3): CG AT-200 or the upgrade version FC200

AT-200 will give you pinout connection

check AT200 or FC200 boot loader reading and password reading wiring digram

Add EDC17C56 (ADAPTER) options in <10-BOSH-ECU-ADAPTER>
But VVDIProg can only read edc17c56, cannot write this ecu.

5). PCM–FLASH

reads perfectly, for example reading a bmw x5 edc17c56

There are some other programmers that can read it no issue, for example, CMD Flash, VF2 Flasher
