hmm i use cobb stage 1+ map and passed my inspection perfectly with that map on the car in my country...
Also COBB stage 1 and stage 1+ maps say this in their map notes:
Quote:
50 State Legal.
This calibration is legal for use on Emissions Controlled Vehicles in all 50 states when used in accordance with the manufacturer's application guide because it has a California Air Resources Board (CARB) Executive Order (EO) number: D-660-7

https://www.cobbtuning.com/maps/bmw-...age-1-fmic-map
so doesnt this mean its legal to run those COBB maps in California?
https://ww3.arb.ca.gov/msprog/afterm...eo/d-660-7.pdf
So maybe consider running Cobb stage 1 and have it all be legal? No more uninstalling and 8 step programs to pass it?
EDIT!
I just realised that this CARB document lists Z4-s from 2009 -2012 and doesnt list newer n54 Z-s... so it doesnt probably work on a 2015 or 2016 car.... bummer
Thats also probably why they dont list Z4 on their site anymore... too confusing to the customers... and probably better to just not list z4 at all...
but in reality... their stuff works on earlier n54 Z4-s and evenmore is legal to run...
