Hi all,
It's been a while... hope everyone is doing well... and I missed everyone at BRBS this year.
Well, I am looking for some troubleshooting guidance before I get my '08 Boxster S smog. Now that I'm in California, they take this stuff kinda seriously (not something I'm used in when living in FL).
I've tried twice following the BMW drive cycle (2:10 @ cold idle, 3:15 @ 28mph, 15min @ 58mph, 5:00 @ hot idle) to get my DME in a ready state.
After which, my Durametric shows only the Evap (gas cap seal) and O2 sensor heater are in Pass (ready) status. However, my catalytic converter efficiency, O2 sensor and Secondary-air system (SAI) are fail (not ready) state.
My understanding is that the DME cycles through the SAI readiness during the 2:10 cold idle cycle. However, since the SAI still shows fail/not ready, I don't know if there is a problem with the SAI? I have no CEL/code related to SAI. Is the SAI not activated b/c the ambient temp is not cold enough for the pump to kick on, and therefore it didn't cycle through?
I suspect the O2 sensor, and therefore cat eff, could be result of my FVD tune. I'll have to flash back to stock if that makes a diff.
For now, I am hoping to get some guidance on the SAI issue.
Thanks!
Cris
