    Bar to PSI in Huracan MMI for tire pressures

    Bar to PSI in Huracan MMI for tire pressures
    Is there a way to get the MMI to show PSI instead of Bar for tire pressures. I live in the US and the sticker on the door sill states recommended tire PSI but the MMI shows Bar which I don't have an easy way to convert. I would think swapping it to PSI requires holding a button down somewhere but I cannot locate where to figure this out. Any help would be appreciated.

    1 bar = 14.7 psi

    so if it says 2.2 bar = 2.2 * 14.7 = 32.34 psi

    I don't know where the button is but I know the conversion.

    Thank you for that. I'll keep it handy.

    There has to be a button somewhere in the MMi to convert it. If anybody knows please advise because when at the track it makes it kinda tough when you have to get your calculator out in between sessions. The heat on the Pirelli's goes way up causing the pressure to build so maintaining it at the optimum PSI is important.

    I asked to have it set to PSI when I was in for annual service and service manager said there's no way to change it.

    I asked for a similar request, as there are no Benzina stations in my country, and stores don't carry Olio.

    No way to set it the PSI on the current cars. Maybe 2017 MY might get it. I just do the conversion or happy if the signs are all green (NO in the tires so the numbers are pretty stable).

    10/4 - thanks all. Conversion ratio in my phone now and it's all good.
