Hello, I'm doing a wideband conversion on my 02 225TT. I've got a wideband ECU (06A 906 032 HS) from an 02 GTI.

Can someone tell me the safest way to go about this? I think I should use Argdub's tool to first save a copy of the 95040 EEPROM? Can I copy that from the narrowband and write it to the wideband? I assume if I do this, the keys I have will still work?

Thanks!

Thanks, this worked no problem. I made a bench harness, put the ECU in boot mode and successfully copied the 95040 EEPROM the first try. I haven’t tried to start the car with the wideband ECU yet…

I just purchased Eurodyne Meastro and I have a question. The info that comes with the Meastro cable says that it will be locked to the “car”, does this mean it’s locked to my vehicles VIN? If this is the case, will it be locked to the VIN of the wideband ECU (this will be the ECU I do the initial read with), or the VIN of my narrowband TT?
I’m assuming it will be the narrowband TT VIN, because the vin was copied over when I cloned the ECU?
Thanks!
