Thread: Nanocom evo - height calibration

Hi guys

this is possibly (probably) a stupid question... but..

Last weekend in the watagans my suspension faulted and dropped to the bump stops (down a pretty rough track), in a bid to try and get the car to raise I used my nano com evo to adjust the height calibration hoping it would force the car up.

In doing so I'm now concerned I have permanently changed the normal setting for my car.

Does anyone know how to re-calibrate it so that when I select 'normal', 'access', or 'off road height' the car responds with the appropriate factory heights? I'm worried i'm driving around on 'normal' setting and its actually sitting higher than it should

i have just worked through a re-calibration of all 4 corners on the D3 as I had replaced all the controls arms. i was using a GAP IID Tool.

I started by trying the calibration sheet / calculations but soon cottoned on to the essence of the adjustment.

Start by checking your heights in normal mode.

For the D3:
The normal height for front is 466 mm from top of wheel arch (internal) to centre of axle.
The normal height for front is 485 mm from top of wheel arch (internal) to centre of axle.

I call that the Mechanical Zero.

( This equates to between 190 and 200 for the constant ( fudge factor ) aka 'Calibration Value'. )

the procedure requires a full tank of fuel, all your crap out of the back of the car, and all tyres at normal pressure. This is to ensure repeatability.

If the heights are all over the shop I suggest you make a note of the calibration values that are in it, then put them all to 190. Raise the car to off-road height, while rolling slowly, then lower to normal height while rolling slowly. Put it in Tight Tolerance Mode if you really want to be fussy.

Measure wheel arch to axle centre. see what you got.
If the heights are all close, drive it squarely over a large domed speed hump at approx 20kmh, and see if the front or the back wallows to one side when it drops down off the hump, that might indicate uneven pressures side to side. If that happens it still needs tweaking and you need to bring the soft side calibration value up by say 5 at a time. until that axle is even height side to side. It then might be too high so reduce both sides 5 at a time to bring it down to close to 466mm front or 485mm rear.
The calibration value at 'mechanical zero' at normal height is allowed/expected to be slightly different across all 4 corners but the change in height / change of calibration value should be fairly repeatable.

For example, I ended up with:
front left - 198, front right - 205.
rear left - 190, rear right - 190

Shoulda checked them several years ago when I got the diagnostic tool.
