Greetings,
I'm using DELPHI DS 150 diagnostic tool,but there's no option for matching,what tool to use?

If ECU and UCH are not from the car, first you must do ECU virgin. You need key with antitheft on UCH working.
If you connect a virgin ECU to a working UCH with the write key, it will match to the car putting ignition on.
