Yes "40" is for the North American 500T and the gauge actually works. Now it would be nice to know what all the other bytes do in the custom proxy window. I have a 2013 500T and put a 2015 TFT in and that gauge didn't work so I tried to use a 2015 BCM and everything worked but the side marker lights and I kept getting a brake light bulb is out when stepping on the brake pedal. So I am wondering if that can be fixed by re configuring the BCM.

Oh wow, excellent info. So the throttle position works with the 2015 BCM installed?

Yes but side marker lights do not work and I kept getting a brake light out message out after stepping on the brake pedal. So I took the 2015 BCM out and put the 2013 back in changed that one byte to "40" and the turbo meter works but not the G force. Noe I am trying to find out why the marker lights don't work with the 2015 BCM.

There might be a resistance difference for the brake lights. You can try adding a 6w or 50ohm resistor to the brake light circuit to see if that helps. As for the side marker lights, I'm not sure. I assume the other signal lights work without issues and it's just the signal lights in the fenders, or, are you talking about the running lights on the front and rear fenders of the car that come on when the car is on?

I am talking about the lights that are on the front and rear fenders. the ones in front of the front tires and the ones behind the rear tires. I am looking for a wiring diagram for the 2015 to see if there is a difference between the 2012. All the plugs are the same but they may have switched the way wires are hooked up. It could also be that the configuration in the BCM is slightly different. The problem is I can't find the 2015 wiring diagram, I have the 2012.

If anyone can get one, it would be the guys on www.fiattech.com/forum

I'd suggest asking there. Simply ask for the diagrams/manual in its entirety. If you get into the details it'll just get way off topic haha.

yani would it be possible to send me some information on what each byte does on the custom configuration screen or can you direct me to where I can get this information?

How can I change the bcm from 2012 model to 2015 model? Must I buy a new one or can I buy a used one? What is about programming VIN and keys?
