Question:
How to read and write JCB Delphi DCM3.3 ECU? I have MagPro2 x17 master; Flex Master; Ktag 2.23 ; Kess 2.47 ; No clue about it. Read/Write is it ok? Obd? Bench? Boot?
Solution:
Kess V2: Not read it.
Flex: no protocol for this ecu.
Ktag:
genuine tool is fine, ktag clone need luck. Clone Ktag is not a good choice for DCM3.3. There are available 3 different versions of that ecu. The clone tool does not work with all. Need to use original tool.
Review:
When i try to read, then ktag EU Clone 7.020 ksuite get error “Hardware configuration not supported: send the LOG files to the software provider”
I have checked 10x connections, all ok and power supply is 13.5v. and ecu waking up when start connecting.
Foxflash: read/write via bench or Jtag

For the reading & writing procedures use the FLAT cable F34NTF53
Connect the wires on the pads avoiding any short circuits.
METAL POSITIONING FRAME CONNECTION
For the metal positioning frame connection are required the F34DM036 +F34DM037 adapters,
JTAG pads for the communication are placed below the microprocessor.
Set up the base adapter F32DM036 with the F34DM037 adapter as displayed in the following picture.
Verify the PIN 1 location and connect the pin 18/BOT to the corresponding clamp on the base adapter F34DM036 as in displayed in the following picture.
Place F34DM036+F34DM037 adapters as displayed in the following picture.
