Latest generation Fiat Talento is basicly an Renault van. Not much is supported

Me again, I tried again with the (good) red cable called OBDLink SX but there is still no connection to the ECU. Tried also with the green adapter, same thing. My problem is, that the ECU is not releasing the fuel pump. When I bridge the fuel pump relais, engine works fine. So, the ECU is not dead,...

You need to select fiat ducato of the same spec.

Have performed a few adaptations/service resets/ proxy alignment to Peugeot Boxers with ducato selected as vehicle.

I am thinking a software bug. Try to update to the latest version 5.3 instead of 4.6.

Probally will be in the next MES version, new versions come out sometimes in half a year and sometimes a year. You can check the history here: https://www.multiecuscan.net/ReleaseHistory.aspx

Any problems driving the car of shifting?

What is the problem you are facing?

Can you upload your original proxy code?

Witech is indeed not useable to perform modifications.
