Alpha-N and OBD Readiness (Emissions)
In addition to working on my MS45.0 to MS45.1 conversion, I’ve been hard at work tracking down the parameters responsible for OBD readiness monitors in the Z4/Z4M MSx70 series of ECUs. I’m happy to report that I have been able to get ALL monitors to show complete/ready with an alpha-n tune. This is not “forced readiness” since the ECU requires the emissions equipment (cats, oxygen sensors, secondary air pump, etc.) to be in place so that the federally mandated monitoring tests are performed. So if you have all the right parts but can’t get the monitors to show “ready” with your alpha-n or supercharged tune, shoot me a PM.
