Would Uwe from Ross-Tech be of help? Or are they 'protective' regarding such information?

i could be in way left feild but it looks like the first three digits correspond to ride weight and height and handling.

it also changes the level control buttons.

ok, ive gone from 10000 to 29900. all i can say is that 29900 feels the best.

the last two digits don't do anything.

my guess is that the numbers 100 to 299 indicate weight.

stock coding is 25500= 2550 killos is 4900lbs, my allroad weights 4550lbs with driver at the dump.

so, by punching in the max it gave me the same feel as a 2004 s8 in handaling.

you go threw the adaption like you were going to 402 is but do something else?

this keeps the car low but tells it it has more weight? wouldn't this just raise the car? or am i missing something

I would love to get better handling out of my AR
I am an aggrieve driver and like to turn quickly
I have the Apr 91 flash Hsport sways and 255/40 tires

Interesting, I will try that and see what changes take place.

The only thing that the system has control over is pressure in the bags and by extension, the ride height. What you might have discovered is a way to change base ride height via soft coding of modules instead of doing the 402 mod.

It is also quite possible that it really is the weight of car which might affect how the module reacts when car is driven.

What changes have you observed after recoding it as far as buttons go?


Thanks!

it seems the lower the code like 13300 will make the suspension feel like ****. spongebob kinda. and the buttons for up and down are sluggish and 4th doesn't exist.
on the other side, 29900 feels nicer then my TT, and the buttons are faster in reaction going up and down. and the car feels like it has more low end torque and power,.


try it at your own risk.

It probably just keep the baseline height lower or higher hence the feeling of less floatiness when number is higher.

I will recode when I have time and whip out the ruler to see if height changes on the same suspension level when module is recoded.

at your own risk, you and a buddy driving can recode the modual on the fly.
(29900) so far is the best.

and i have a hunch that the level control button can be modded so it will make the control unit faster. thats my goal tonight.
