4.8is Ride Height Calibration
 

Used the search function but i can't find any definitive answers. I've just had two new Arnott bags fitted to the front end and have a friend with the GT1 system. Does anybody know the correct procedure for the ride height calibration, correct values etc ??

Not to bring up an ancient thread but I have searched for hours now and cannot find the proper ride heights (ground to fender). I am suspicious mine is sitting low but i have no codes. Just a harsh ride...

thanks

Here you go... but the mesurment is from the bottom lip of the rim to the bottom of the fender...

_______________ 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

:iagree:i was just about to dig up the old post with this info... thanks Rob...:thumbup:

Haha, Last time you posted that, I copied it into a text doc. for easy access :D

Hey guys I thought I would post up since I went out to measure my car today, and I think I need to get my ride height calibrated correctly, I always suspected that my car "looked higher" than it should with Sports Package (so I have sports suspension) and I also have EHCII dual axle air suspension like the 4.8is on my 3.0i.

I measured from the bottom edge of my Style 168 wheels to the bottom of the fender arch, and measured just under 29.5 inches (749 mm!), and about the same on the rear as well. Although I have dual axle suspension I assume I should be using values of 707 front and 709 rear, I can't believe its possible that last time my height was calibrated it was 40mm off!

Is the ride height value 707mm / 709mm ONLY for 4.8is? Or does it apply to all models with 20" wheels and EHCII (the rarely equipped 3.0's and 4.4's)? I'm just wondering if I should lower to 722 and 724 (non-sport values), as that is already an inch of lowering from where I am now.

When I calibrated my suspension, DIS told me that the sport suspension wasn't detected. I don't know why.
You can still make it calibrate to where you want it by doing the math and putting those values in the calibration routine...

Ricky_Bobby, you have 20" wheels and 2-axles air suspension. I'd go with 707F/709R.
Personally, I would lower it another inch from that value.

That must assume the OEM tires are on the X and inflated to recommended pressure.

I just calibrated my ride height last week
bought gt1 with inpa/ncs/navcoder bundle from ebay
used INPA
very easy to do, it tells me to set height to 707 front 709 rear
the program is so easy use

F9 to access e53, than click on the ehc-2
than hit F6 to activate
F5 to calibrate
press F1 to open the calibration and just plug in the height difference you want in MMs

I measured my heights and my back right was higher than the left so when it asked for rear L - R
I just typed in -6 for right side to raise it slightly
typed 8 on both the front because I wanted it lower
press ok

2 seconds later the airide moves and your done

F10 to exit that screen
than you just drop your bags then raise it back to normal and recheck your heights to make sure its good



if you are near Canada BC Vancouver/delta/Richmond I can do it for a small fee
