    The suspension ecu already has plausibility checks for airspring height increase and reservoir pressure increase for compressor run time that prevent the compressor from running without sufficient effect.

    The only modification I'd do is to fit a larger or 2nd reservoir now that the reservoir pressure has been lowered from its original design pressure in order to extend compressor life, which is probably more due to a dryer that is too restrictive and too easily clogged if not serviced or replaced regularly.

    I could possibly source 20lt (water capacity @ 1atm) cylinders for reservoirs for about $40 or $50.

    20l are usually 200mm. OEM is 115mm. You could get a 120mm to fit on the opposite side.

    Could work if dia includes legs otherwise it is

    Sorry that should have read 20cuft @ 220bar, 4lt.

    About 100mm and 400 to 500 long.

    Thats working pressure, test pressure of approx 350bar by memory.So you could get it filled to max presure, then regulate it and not have to run the compressor for a while....

    The working pressure of the EAS is over 200psi (13.8 bar)so you would well within the pressures.
    Would easily fit a couple on the opposite side. Could attach a compressor with a dryer for emergencies and could be used for tyres as well.
    Can't afford the mod at he moment but would be useful as I have an air off kit which just works for airing back up from off road to on road before it runs out of puff.
    Are they a normal air cylinder with one outlet or a tank with multiple?
    Maybe mods should move some of hese post to another thread?

    Might want to check you Maths. 200psi isn't 138 bar. Closer to 13.8 bar.
