    Default COBB Accessport V3 - Gauges and normal readings for MPS 6

    Hi guys, this post is meant to be complementary to the one @SarcasticOne did here: Cobb Access Port FAQ

    Anyway, I just got my COBB Accessport V3 today and installed it. When i was looking at all the gauges that are available i must admit i didn't understand what they all meant. I have looked over this site (and the COBB one) but cant seem to find the answers to what all these gauges mean, and what their normal readings should be.

    Because i am sure that others have the same questions / or know the answers, ill try and put together a thread that can cover everything.
    These are the supported monitors (gauges) for the MPS 6:

    Monitor (Gauge) name Monitor Definition Recommended Min Recommended Max

    Wastegate Duty-------------------?-------------------------------------------------------------------------------------------------------------------------------?--------------------?





    I have attempted to fill in the definitions where i believe i know the answer, but i have no idea what the ideal readings should be. Can anyone help fill in the gaps?

    Also, here is a screenshot i took when i was driving around this morning. No idea if these readings are good / bad (apart from the KR, which is good). Note everything is stock on the car apart from a CS SRI + TIP, and HPFP is in kPA.

    Default COBB Accessport V3 - Gauges and normal readings for MPS 6

    Many of those readings will vary from car to car as flow characteristics vary, aswell as warm/ cold idle, ambient air temp, altitude above sea level; and weird things like battery voltage.

    All parameters definitions can be found in the Cobb AccessTuner Race help file so that way you can get a better feel of what each value means. It's about 110 pages or something but gives a great overview to our platform

    Thanks Rayd, ill download, and put in the definitions soon....

    I understand that the values will be different from car to car, however there should be a range that is recommended - like that Air intake temp, maybe 15-30 Celsius?
