I know there's a adapter harness for N54 for use with N20 sensor. Is there any adaptation needed when using it on a F10 n55 ? The plug plugs right in but i've read somewhere that i have to invert the contacts for it to work. Can anyone confirm ?

I can only confirm re-pinning the stock connection works for "harness type A" PWG N55s. That is the car I did the re-pinning on when I saw the plug fits in but upside down... Not sure what harness the EWG N55's have.

this is PWG, i inverted the wires but still am getting an error for some reason.

this is after flashing MHD with N20 sensor option

I use the N20 TMAP on my 2013 F10 N55 PWG, no changes to the harness at all, just unplug the stock 2.5 bar and plug in the new 3.5 bar N20. I don't use MHD, but I use a JB4 and it works properly.

This is exactly what we figured out yesterday. Once you flash MHD with N20 option and plug the sensor w/o modifying the harness it all works!

Thanks for your input!
