BC Racing Coilovers Review - Another EHCII System Removed

It removes EHC2 from ZCS (central encoding key) which is the guide line how NCS codes the parameter values on every module.

One bit can include 1, 2, 4 or 8 or any sum of these. (A=10, B=11, C=12...)

Then, since you have a 4.8 you will have to code the DSC to think it's in a 4.4i N62 using NCSdummy or you will have a dsc error and light on the dash.

To clarify, I should not be using the “code car” function at all? Should I be writing the ZCS onto the EWS and KMBI then closing out NCSExpert?

You can use code car. But will likely see an error once ncsexpert reaches a module that is either not present, or not communicating. For me that was the Bluetooth and dsp amp as I had removed them. Was just easier to code the specific modules associated with the zcs.

And yes, as clavurion says, don't delete anything from the daten folder. Everything is done in ncsexpert. First step should be to read your current zcs in ncsexpert. Then you can modify the strings as necessary to delete options and then code car. If you post your zcs we can help with what it should be changed to.

I’m not sure how to post the ZCS. Here are some snaps from the screen in NCS. I changed the 5 in the 8th digit of SA to a 4. I checked the checksum box then coded the two modules that have the ZCS in them (EWS and KMBI). The EHC2 module is no longer there. The trifecta of warning lights are gone but the Self Leveling Suspension error is still on the dash! I’m getting closer.. I really appreciate both of you responding and helping me.
Edit: Not sure why the pic is coming up sideways.

I’m also getting an error at changing ZCS on the EWS module when I code car. No answer. I can change the ZCS I. That module manually but have no idea how to check to see if it actually worked. I also changed the dxc to 4.4 without air in ncs dummy. Still have the self leveling warning on the dash

If your original SA is as shown in that picture. Your new one should be 212B800108ADE90FS

You would enter that, then delete the last bit in the GM (7 in your case), delete the last bit in the SA (S in your case), and then delete the last bit in VN (E in your case). Click "calculate checksum," and okay.

I did all of that and went through the coding process however the Self Leveling error message is still there. There is no longer any sign of EHC anywhere except that pesky warning message on the dash. I wish the air suspension was never taken off. This is monumentally frustrating.

Code your LKM (light control module) with the new ZCS.

I went through every module and coded every one that had ZCS Schreiben as an option. I believe LKM didn’t have that as a job option. I can recheck. I don’t have LKM I have LCM and ZCS Schreiben is not listed as a job.

I am having absolutely no luck with this. How is there still a warning message when the EHC has been deleted from the ZCS?!?! This is beyond frustrating and I really wish whoever did this conversion would have just left it the hell alone. It’s easier to fix what’s supposed to be there than try and learn an entire new skill.
