Hello

My advice is... just forget it. There are hw differences between the ECU's. I've never managed to replace an ECU hw>100 with a hw<100 one.
And the 2 car is very different. For example 1 vs 2 O2 sensor, different camshaft sensors, CAN configuration etc.
And probably the BCM configs are different too (ABS, door number, fog lamp etc.).
So it's much easyer get another ECU hw>100 and copy the old ecu (transform if needed) if You have the tools. Or as You wrote get a "virgin" one with same numbers.
