hi there all. i need some help in reading a ecu from gwm h5 vehcile. 2015 model 2l. the engine light is dead and coil light. vehicle not starting. secondhand ecu engine light comes on. which protocol should i use to read and write info from original ecu to seconhand ecu. i use ktag clone. many thanks in advance.

Hi members. Please should I return computer boxes due to difficulty to work on. Looks like Delphi ecu's are a headache. What would be the next move to get ecu programmed. Agents maybe?? Many thanks in advance.

you need a good geniue flashing tool to work with this ecu.

on your photos you have choose dcm3.7 with protocoll 388 and mcu 72513...

but on your ecu photo it´s an dcm3.7AP...
it should be mcu72544...
try other protocoll 1094/1096/1100/996/931...
check out this one, if they support this mcu...

but don´t know if it´s possible by clone...

hi friend. i double checked. mcu is 72513 from original ecu. so i think selection is fine. maybe ecu dead. ktag cant pull a read from it. thanks

What kSuite you used to read with Ktag clone (what version do you have)? Did you manage to find out how to write with KTag clone?
