Lightbulb

Finally completed my full ZCP suspension install.

What I feel following my course of ZCP mods:
1. OEM non-ZCP's Comfort mode is really comfortable, and Normal mode, well, normal. However, the Sport is quite harsh because there is no dynamic control and all the small and big bumps feel harsh.

2. After ZCP coding done by Mike Benvo, the entire car became stiffer for all the three modes. Good thing is that the Sport mode becomes a lot more compliant over small bumps. Still harsh over large bumps but the control is much better.

3. After ZCP suspension install, the entire car now becomes softer than after just with the ZCP coding, which makes me think that the ZCP coding must be use in conjunction with the ZCP suspension dues to the strut-reading by the EDC computer. Now all three modes are back to OEM non-ZCP feel but the Sport mode is now a lot more compliant. The difference between Comfort and Sport is not as dramatic as with non-ZCP but you can still feel the difference, especially hard cornering.

Conclusion:
I think for anyone who'd like to retrofit ZCP-suspension to non-ZCP M3, you need to get both the suspension and ZCP EDC coding for the entire system to work correctly. Simply install ZCP suspension or just upgrade ZCP software is not enough because the computer might not be reading the strut correctly, evident from the fact that my ZCP-coded only becomes stiffer for all three modes. In this case, I think the ZCP-coded EDC computer interpreted non-ZCP strut to be under rebound (because non-ZCP is 10mm higher) and hence pre-stiffen the struts.

As far as the lowering goes, before ZCP suspension I had 2.5 fingers gap at front and 1 at the back. After the lowering, 2 front and 0.5 back.

Hope this helps.

You need to contact someone at BMW, give them all the option codes that came with your car, and they'll let you know what the PNs are. I worked with scottbmwhn on this forum.

Looking from your pictures of the shocks, did you just order item 1 from picture here or other parts for the rear?

You should only need the shocks and springs on the hardware side. You'd still need to have your software updated to the ZCP-compliant MDM and EDC Sport settings to truly finish the retrofit.

The PNs on the struts changed after I did my retrofit. Apparently BMW will do that with certain parts as it consolidates its catalogue of parts on occasion. The part itself should still be available as a different PN, though.

You can order the parts from us or from BMW directly, and we can perform the proper programming to complete the retrofit remotely.

I don't have it, but any reputable shop should be able to code it for you. Try EAS first.

Yup, still have her, though I'm moving on to the next thing soon. Not sure what I'll do with the M3 yet. Tempted to keep it because of the amazing engine.

I started my own company in El Segundo a few years ago, so I just walk to work now, which is why we haven't seen each other in a while

How are you? What are you doing these days?
