Now that I drove my 05' LS430 UL for a week, the softness of the air suspension is starting to bug me. All my previous cars are sports car with very firm suspension, and we prefer firmer suspension damping. Now don't get me wrong, I don't want the LS to ride and handle like a sports car, I just want it a tad firmer, like sport suspension from BMW or AMG cars, the firmest setting on the AMG E55/E63 is perfect for me. I don't like the "soft" feeling, it gives me motion sickness.

And yes, the sport mode is turned on, I also adjusted the height sensor to lowered the car to make it all even. Right after the car was lowered, the suspension firmed up, it was exactly the firmness I wanted, but after the car is driven for a while, it softened up again, I guess the system self adjusted back to it's previous firmness setting.

With the way the car ride now, it is a little soft for me and my wife.

I know the ASC680 Data System Controller can adjust the firmness of the shocks, they call it the TEMS adjustment. My question is, how many setting it allow and how firm does it get? I assume it get firmer then the stock "sport" mode?

I searched and read most of the thread regarding the ASC680 Data System Controller, but everyone just talked about the height setting and no one mention anything about the TEMS (shocks firmness) setting.

Anyone knows?

Thank you

 

Please let me know once you figure it out...
I am so confused by the controller, I hope there is an English manual!

Also, like I mentioned, with a bigger wheel and low profile tires, you will feel the difference, but the car still drives smooth and soft, just better.

 

According to the ASC680's website, the controller can lock the firmness of the shocks to it's firmest setting available. I am just wondering how firm is firmest? The Japanese manual don't say anything about that? Can you scan it and post your manual? Look for the term "TEMS" setting.

Yeah low profile tires would make the ride stiffer, but the struts are still too soft for me.
