I just got my speedo pigtail connector in today for my M6 to 700r4 conversion. I spliced the wires together and took off. Rolling out of the driveway I was relieved that I had signal. However, got on the road and it looks to be about twice as fast as it should be. Someone told me that the signals for A4 and M6 were the same in the PCM. Do I have the right sensor? It's the large round magnetic sensor. I'm really confused.

 

Just play with the tuning file until you get it right...I don't think that the signals are the same BTW.

 

That's what I was gonna try. However, like 4 different people said the signals were the same. I guess not.

 

I had to put in a funky gear ratio in my tuning when i swapped to an M6. I think the factor was 2.36 for me (I have 3.73s and told the PCM I have 1.58).
