Hello,

want setup Active Curve system on w164 from w166, only one question about is there way to activate it in ECU?

 

Yes, you can activate it in the computer, but I highly doubt the wiring harness and other hardware exists. If you want active curve, you're better off selling your current W164 and finding one with active curve. There is more to it than just the lamps.

I also highly doubt W166 parts will work. X164 and W251 parts might work.

 

any 164 or 251 versions not have active curve, only from 166 they started to install it

 

I don't see how this is possible.

 

Tell that to my R500 that has active curve.

 

I think you missed with something, or show your vin

 

Oops, I thought it was the headlight system.

No, there is no possible way to retrofit the Active Curve suspension system. The closest you will get is having ADS and putting it in sport mode.

 

actually I think it's possible, w164 and w166 have not so much difference, I need 2 stabilizers and ECU for it, only question in software which may be not supported by main ECU

 

You would also need a way to get steering position and shock position at minimum to the Active Curve control module. You might also need accelerometer data as well. I highly doubt that is possible without some major reverse engineering on the 164 and 166 control systems. You're much better off finding a 166 with Active Curve.

 

as I guess there is not activated option for it in w164
