Good day

I am having a problem with cloning MED17.5.25
I am reading ori ECU in factory mode and writing donor also in factory
P-Flash and D-Flash
Ori ECU starting the vehicle and donor ECU not starting
Am i missing something?

Regards

Does anyone know if Porsche falls into VAG (immo in OTP) category, no direct cloning possible? Asking specifically about Porsche Bosch MED17.1.6?

here is a other pointer, immo level WFS4, WFS5 can be cloned by merging immo data, WFS6 and up NOT
ALSO you need SAME donor so HW BUILD, BOSCH number must match

in short for example, HW18 to HW25 does only work if you do "update" SVM coding online else car will start but with ecu errors

I found a few times that the SW version must be the same. You can read with VAG Com SW Version 4 digits.

software does not need to match as you use ori flash in donor, if not you need to edit brand and powerclass "if" you use "immo off"

immo/OTP IN eeprom only
