Hi- In theory the 607 rev5 bin should have the immobilizer removed and should work for what you're trying to do. I'm in the US, so I never had to deal with those on any of our cars. When I did my first dive into this stuff I used the info from the M4.4 Wiki to set my stuff up and flash through Tuner...

The 4.3 XDF is different.

Message me with an email and I can send the 4.3 XDF/ADX over to you. I used them twice to flash the R bin to an M4.3 ECU.

You have to have a different instance of the flasher as well as the default TP CheckSum, as the M4.4 one is different.

On a different forum I believe user dougy could install the new tensioner on the old blocks by grinding a bit of material of the block. He did this as he was building a R version engine with a 2.3T block. However which tensioner exactly, I can't say. Take my info with a grain of salt of course since...
