    I am looking for some help in setting up my Scan Guage II. I have seen several posts on setting the unit up to give accurate boost pressure readings. My problem is the process for entering these changes into my Scan Gauge, if it is a type that can be modified? So any help for a novice would be appreciated.

    User manual is here.

    I haven't tried customizing mine yet but I understand if yours has Xgauge, your can set up your own gauges too. Good luck.

    UK .. I actually live right by you and have seen your car a few times. I have a SGII set up on my car and I've got the display showing MAP. If you can't get the setup right, I'll be happy to come over (or meet you somewhere) and lend a hand.

    Thanks for the offer. I need to check if I have the Xgauge feature, today. I bought this used off Jan at RMW, so I don't have the original paperwork. It seems pretty easy to check. I'll let you know.

    This has bee quite for awhile so let me ask a set up question. The back light on mine is really dim, even on high setting. Very hard to see in the day light. It also says there are 63 possible colors. but I only see four. Am I doing something wrong or is this the way it is?

    Also - the display on these is affected by high temps. Mine sits on the dashboard. When it's hot out and the car is parked in the sun, the display if pretty much unreadable until it cools back down a bit. Then it's fine.

    Thanks very much. I like to watch training films more then reading the manual.
    Learned that in the Army, way back when they had training films. :Thumbsup:

    Good information. The green back light is the only one that seems to stand out for me.

    I was driving around this weekend and suddenly remembered I wanted to get my Scangauge reading true MAP. So I checked that it does have the xgauge option. Now I just need th instructions on programming the boost correctly again. Can anyone point me in the right dircetion?

    I "borrowed" this from one of Blimey's posts on a, um, different site....

    Atmospheric pressure starts at 14.7psi at sea level, and drops approx. 0.5psi per 1000 feet of elevation...

    For 14.3PSI atmospheric pressure (about 800 ft elevation):
    TXD: 68 6A F1 01 0B
    RXF: 04 41 85 0B 00 00
    RXD: 28 08
    MTH: 00 91 00 64 FF 71
    (note - you don't enter the spaces - they're just to make it reading-friendly)

    For other pressures, just substitute the following for the last four characters of the MTH string (replace the FF 71):
    12.0 -- FF88
    12.1 -- FF87
    12.2 -- FF86
    12.3 -- FF85
    12.4 -- FF84
    12.5 -- FF83
    12.6 -- FF82
    12.7 -- FF81
    12.8 -- FF80
    12.9 -- FF7F
    13.0 -- FF7E
    13.1 -- FF7D
    13.2 -- FF7C
    13.3 -- FF7B
    13.4 -- FF7A
    13.5 -- FF79
    13.6 -- FF78
    13.7 -- FF77
    13.8 -- FF76
    13.9 -- FF75
    14.0 -- FF74
    14.1 -- FF73
    14.2 -- FF72
    14.3 -- FF71
    14.4 -- FF70
    14.5 -- FF6F
    14.6 -- FF6E
    14.7 -- FF6D
    14.8 -- FF6C
    14.9 -- FF6B
    15.0 -- FF6A


    On the R56 - use TXD of 07DF010B instead!

    And we're at about 800 feet here in Mansfield?

    Precisely? I'm not sure. But, AirNav.com has DFW at 607 feet and Love Field at 487, and City-Data.com lists Fort Worth at 612 feet.

    YesIFit, thanks for the airnav.com link. Columbus is at 815 feet...gives a new meaning to Dallas being "down south".

    Has anyone tried programming the X-Gauge to read horsepower?

    ScanGaugeII - Add-A-Gauge

    Does the MINI provide the information for the scangauge to work correctly when programmed?

    Or intake air volume?

    OK, so I programmed one of the x-gauges to read boost. What sort of range of numbers should I be seeing?

    I'm using the SGII. I never checked to see if it had the X-Gauge function. If it does I will see what I can do about adjusting it to read manifold relative pressure (MRP) like a regular boost gauge versus the manifold absolute pressure (MAP). If I was flying an airplane MAP would be good but in a car MRP is much more useful for checking boost leaks and to make sure appropriate levels are attained.

    Based on what I've seen in the R56

    MAP: 4 psi @ Idle
    4 to 10 psi 6th Gear at freeway speeds (throttle dependant)
    23.5 to 25 psi @ WOT

    I'm in Southern California so 14.7 psi is a good assumption number for nominal air pressure.

    So in relative pressure (like a boost gauge)

    MRP: -10.7 psi @ idle (Manifold vacuum)
    -10.7 to -4.7 psi 6th Gear at freeway speeds (throttle dependant)
    8.8 to 10.3 psi @ WOT

    I don't know what levels of boost the Superchargers generate for the R53s but I assume it's probably close. Hope that helps.
