    What happens when you select "MAP" instead of "Boost?
    Thats exactly what it should do and always has, I have not tried map. I honestly am starting to think its the beta firmware I am running. I may try to go back. josh@cobb can you chime in here and see if you can lend any insight?

    it does seem like yours is only reading CP and the tip in discrepancy is due to throttle plate position. Maybe Cobb changed it... my logs were from sometime ago and I don't remember the last time I updated the AP. Did you try the MAP channel?

    Cobb changed it, spoke to Josh he said its most likely the firmware but the V3 reads vacuum still. Ill prob be upgrading soon anyways.

    Old thread but I am running into an issue reading back the boost parameter with my COBB V2.
    My reading is between -12 and -6 psi. Car drives like a raped ape and I can see that my boost targets get hit.
    Mean ABS boost reads +32psi. Is this a sensor issue or a Cobb issue?

    Unfortunately you will not find too much Cobb support these days on the N54.

    I don't know if it's a sensor issue but I'd say try another tune and if it still happens you know it's a sensor.
