    I only noticed it recently after I put the 91 tune on, but whenever I really put my foot in it I get a max boost reading around 60 psi. Any thoughts Cobb? Anybody else seeing this? The number changes, but it's always around 60. uploadfromtaptalk1395331275228.jpg

    They are working On getting the bugs out for this next release. I had a post up about this also and cobbs response is in there. I had 600 plus boost and over 8000 rpms showing on mine. Should be all better soon!!

    Very common, and I have some comical triple digit boost readings! As mentioned, they're aware and a fix is pending. I've quit taking photos of mine. :)

    I started seeing high rpm numbers last night, so I started logging the data. The abnormal rpms only show up on the display, but when I export the logs and look at them in Excel the values are all normal.

    Hmm. That's even more curious!

    What is even more curious than that is if you are logging then you don't get any false readings on the display either. Everything behaves perfectly. Try this: as soon as you turn on Accessport start logging. You won't get any false readings (on the display or in the log). Stop logging, and the false readings will start to appear within a few seconds. Not sure if this is the same for boost, but it is true for rpms.

    Confirmed. While logging the bogus readings are gone. Maybe the polling frequency is slower while logging?

    I hate that... Mine has done it forever. Now that I updated to there new firmware, I have to reset the AP everytime i get in the car too after its been turned off ( the engine ).

    What do you mean reset the AP? Do you power the AP off when you turn the car off?

    No. I always leave it on. Before... When I'd get back in the car , even over night, it would just bring up the gauges like normal. Now... I have to start the car , turn the AP off. Then turn it back on EVERY TIME. I beat this car hard, and because of the state of tune I have it in, I'm always watching knock counts, boost counts, and AFR. I need to borden my horizons on the other readings to get familiar with them and what's normal... But anyway. It didn't do that until the new firmware... No idea why...

    Yup. I am seeing the same thing. Sometimes it will say there is a cabling issue. Turning the AP off and on again fixes it.
