i just finished replacing my charcoal canister (how to coming soon) and blew out the charcoal from my lines, reset all ny DTCS etc etc. Now i need to make sure im good before my smog check which i have to complete within this week before registration prices go up.

I know that i have to wait for my emissions monitors to run their tests and there is a specific "drive cycle" to activate these tests but anybody know what the drive cycle is for our r50s?

thanks :)

since my DTC was a small evap leak, the drive cycle for that particular diagnostics is apparently driving 20 mins with 10 of the mins 60+ mph, sounds simple enough

if i am reading the chart on ec 49 correctly

It certainly doesn't require 60+ MPH. I get a code if I floor it at < 2500 RPM, and I've popped that code coming back from
the beach house on Sundays. Five cycles laater (max speed limit 50 MPH, and I only see that on two of the cycles) the code turns
off. It has never taken less than five cycles.
