Swamp,
does your instrument panel on the bike display in PSI or bar?
just askin'.
For anyone interested, this display can be set to show your unit of choice. Although this is not possible with the GS-911 diagnostic tool (similar to the clubs). I believe that his can only be done by the BMW dealer. I'm sure someone here can describe the equipment. So if looking at 2.1 gives you the squirts and you rather be seeing the old school 36PSI, then mention it next time you book your Bavarian Beauty into A/C for a service.
FYI
Bar:Bar (unit)
The bar is a non-SI unit of pressure, defined by the IUPAC as exactly equal to 100,000 Pa.[1] It is about equal to the atmospheric pressure on Earth at sea level, and since 1982 the IUPAC has recommended that the standard for atmospheric pressure should be harmonized to 100,000 Pa = 1 bar ≈ 750.0616827 Torr.[2] The same definition is used in the compressor and the pneumatic tool industries (ISO 2787).
The bar and the millibar were introduced by the British meteorologist William Napier Shaw in 1909, while he was the director of the Meteorological Office in London.[3]
Units derived from the bar are the megabar (symbol: Mbar), kilobar (symbol: kbar), decibar (symbol: dbar), centibar (symbol: cbar), and millibar (symbol: mbar or mb). They are not SI or cgs units, but they are accepted for use with the SI.[4] The bar is legally recognized in countries of the European Union.[5]
The bar unit is sometimes deprecated.[6] While the BIPM includes it under the class "Non-SI units accepted for use with the SI",[4] the NIST includes it in the list of units to avoid and recommends to use kilopascals (kPa) and megapascals (MPa) instead.[7]
or PSI:
Pounds per square inch
The pound per square inch or, more accurately, pound-force per square inch (symbol: psi or lbf/in2 or lbf/in2 or lbf/sq in or lbf/sq in)/ pressure per square inch is a unit of pressure or of stress based on avoirdupois units. It is the pressure resulting from a force of one pound-force applied to an area of one square inch:
Using unit conversion:
1 psi = \frac{1 \text{ lbf}} {(1 \text{ in})^2} = \frac{4.4482216152605 \text{ N}} {(0.0254 \text{ m})^2} ≈ 6894.757293168 N/m²
Therefore, one pound per square inch is approximately 6894.757 Pa.
Now converting the psi to standard atmospheres:
\frac{1 \text{ psi}}{ 6894.757293 \text{ Pa}}
\cdot \frac{1.01325 \text { x} \ 10^5 \text{ Pa}}{1 \text{ atm}} ≈ 14.69594877551 psi/atm
Therefore, 1 atmosphere is approximately 14.696 pounds per square inch.
