Not sure on that last one. Regardless, if you mess up you can always retry as many times you want. LOL

Or if this doesn't work for you, you can try and manually adjust each corner to your liking.

I think later on I found that there was an article/DIY already on this on the forum. Let me see if I can find that and you can compare DIYs.

Found it but its manually adjusting by measuring. This is in the Service Function.

Well when the module was last programmed I'm pretty sure the values were set to 18" wheels and sport suspension since I got the staggered 20s after I bought the car, here is the values that have been posted on the forum:

_______________ 17"____18"____19"____20"___these are wheel sizes
front axle_______685____697____710____722
rear axle________687____699____712____724
sport fr_________670____682____695____707
sport rr_________672____684____697____709

So looking at the chart, my current programmed values should be 682 and 684 for an 18" wheel, if I go into the calibration and select 20" wheel diameter and then plug in the correct value or 707 front and 709 rear, theoretically the ride height should not change as the 18" height value compensates for the different size wheels?

I'm just looking for the benchmark and to program the proper default height for my 20" wheels for starters.

Then as far as lowering 10mm or so, I would just add 10mm to the correct 20" sport values to give me 717 and 719 mm, or if lowering 15mm I would program 722 and 724, and if I do revert back to default setting just program 707 and 709 mm again?



NINJA EDIT: Now I understand what you mean with having the proper values to start with. If I want to start from scratch what is the operation to be sure I am starting with default values of 707 and 709 mm? Is there a separate ride height default setting that I can access?


Then once I am sure the proper values are plugged in for 20" wheels I totally understand how the system works as far as raising/lowering based on your description

I found an old post of mine. I did not fully understand what that DIY was doing. It is comparing it to a ZERO POINT (default ride height). Assuming the default ride height of a 4.8 will be different from a 4.4, you can't use the same numbers but you should be able to use the same method.

Since we don't know what your zero point is I think you should just go straight to what I'm talking about in this link and set your zero point as you like. Six of one, half a dozen of the other - same result. :D

It should be in the Control Module Functions

OK So the easiest thing is to go into control module functions, set zero point to correct ride height values for starters (707 and 709 mm), and then I can set 10 mm lower if I want to (697 and 699), 15mm lower, etc.


Basically setting the zero point in Control Module Functions you are telling me is a much easier way to program your ride height?

Correct. :D

Just set your zero point to whatever you want your default ride height to be - 697 and 699 if you want 10mm less than normal.

If you don't like it just go back to the same place and set it to 707 & 709.

For further clarification. That zero point method works by raising/lowering your ride height in that function. When you have it to the default ride height you like you tell it that is the zero point.

So, when you go into that function, measure what you have now. That will tell you your current zero point/default ride height.

If its 684 and you want 707 or 697, then manually raise it until its at 707 or 697. There will be an option to do this manually. You will have to measure to make sure you are at the height you want. When you're at the proper height, tell it to use the current height as your zero point.

So, you don't input numbers like 707 and it will automatically go to that height. It does not work that way. It does not work that way in the other DIY either.

Hopefully I have clarified it better now. ;) :rofl:

YOU ARE THE MAN THANK YOU I MISS YOUR 4.8IS!

Thank you and please see my edits. :D

OK I understand, so riddle me this, if my ride height was last calibrated with 18" wheels i'm assuming the zero point/default value used was the 682 front 684 rear according to the chart. Now I have 20" wheels and although it is not programmed, the zero point/default should be 707 and 709 mm measurement since I have the different wheels on?

I guess I'm just confusing myself on how to rectify the measurement to be what it should be with 20" wheels and doing the slight lowering from there.


This might just be too complex for me and I might leave it lol!

Bumping this thread as I borrowed a friends GT1 and didn't know if Twins would chime in:

I tried the zero point method Twins referenced above and its easy for the most part but its not really precise, for example I got my car down to around 710mm last night (which is supposed to be default sport ride height with 20" wheels) but there is a discrepancy of about 3/4" of an inch between the corner that's the lowest and the corner that is the highest.

Yes in the function you can raise and lower each corner manually and then "set the zero point" to lock in that ride height as default, but its sporadic as to how much the lowering and raising does, for example I wanted to be around 27.5" all around (700mm) and I had a corner which was at 27.25 and 27.75, raising and lowering those corners either raised too much or lowered too little. There isn't a set amount that it raises or lowers each time as far as I can tell.

I am also going to try the DIS method on the how-to's, where you manually measure the height offset on each corner, this looked promising as far as lowering/raising in small increments.


tmv also pm'ed me some tips for using the original DIY which is to take your default ride height and add mm's to the setting in the Ride Height Calibration of Control Module Functions in order to lower, this may be best because I can add mm's to the corners that are off and get them to even out this way. My only concern is my base values are not 707/709 as they should be (sports with 20" wheels), so I need to manually measure each corner, then figure out in mm what each corner sits at, and add or subtract mm's to get the corners to sit at the proper values (with the rear sitting a couple mm higher)


Thanks to all who helped so far, I will say already that the ride is much nicer at what should have been the default setting for my X, just need to fine tune the corners then I can take some pics. I will be doing a conservative drop, probably 1/2" or so, I don't have the 4.6 or 4.8 body kit so I feel a conservative drop from the already sporty stock setting is enough for me.
