Default Ucf21 suspension height controllers

Hi all,

I've heard of the field ahc - 10m air suspension controller which I'm guessing is quite old?

Also the datasystems asc680.

Would the datasystems controller adjust the shock stiffness on a ucf21 celsior, from what I've read it seems like it can do?

Doesn't look like the field controller can because it only has two plugs rather than three.

Thanks,
Connor.

Unfortunately in case of a UCF21 you can't adjust the shock stiffness. A UCF11 with TEMS can though.

Thanks for the reply.
The website says that the TEMS section of the controller excludes UCF31's?
I can't see any mention of UCF21's unless the translation isn't very good.

I don't find any good computer translations between Japanese and English. I can easily point out many strange translation results although my English skill is still quite limited.

I myself own a 98 UCF21 Celsior and I also use a Datasystem ASC680. It only can adjust the height. There is no way to adjust the stiffness. I wish I could adjust it a bit stiffer but the only way is to replace all the air struts.

You may know already but the original suspension system on the UCF21's firms up the suspension quite well when in high mode, I can tell the difference between high and normal. The only difference is it raises the height at anything below 80kmh (50mph). I don't think it goes to max firm though, that's possibly only when braking from a certain speed.

But I agree it would be nice to firm it up a bit more.
