Hey guys, So I'm having this issue that is driving me crazy. My SAI (Secondary AIr Injection) and Oxygen Sensor are not reaching "Ready Status" A little background about my car. 2006 Boxster S 3.2L FVD Exhaust system GMS Headers with 200 cell cats - has all 4 O2 sensors attached. 996 throttle body and distribution hose ECU Tuning Group tune I had the car up in BC Canada since 2009 (although it is a US car) and had no problems passing the sniffer and obdII tests - both before and after all the mods except for the ECU tune. I went to get my emissions testing done last week in Texas and failed due to the 2 systems being in not-ready status. I figured it might have to do with the cat delete (ROW) configured in the tune. I sent my ECU back to ETG in California and had them re-flash my ECU in order to re-enable the O2 sensors. I cleared all codes and figured I would start fresh. I drove the car about 120 miles and attempted to follow the drive cycle mentioned in the forums but it was really tough with the roads out here. Everything is in ready status except for the SAI, and the O2 sensor. I can manually start the SAI using the Durametric system so I would believe the pump is not bad; however, I'm not sure that I"m hearing the SAI start up when I cold start the engine. For testing purposes I unplugged my O2 sensors from both bank1 and bank2 and they both threw fault codes which confirms that the ECU tune re-activated my sensors. I've uploaded a few pictures with the results from a OBDII app as well as the Durametric Software to my Google Drive. I'm not quite sure how to interpret the Durametric Voltage results - especially the negative 50 V and -127V - seems quite odd. https://drive.google.com/open?id=0B4ncE-o5M02DeUlLZVlxRV9hX3c Any help or guidance will be appreciated as I'm out of ideas. Thanks, Joel
Hi all, I've been lurking the forum and have been struggling with some CEL codes with my 2000 Boxster S. A little history that I have been battling with P1126 and P1133 ever since changing out the two pre-cat O2 sensors. Then I went ahead and replaced it with a MAF and the car has been code-free for two weeks. Now the problem is that the SAI monitor is still showing incomplete and I've done numerous cold starts. I've read many posts in regards to this issue and saw what the "passing" graph looks like from here http://www.renntech.org/forums/topic/49155-secondary-air-test-readiness-monitor-incomplete/?p=272478 Couldn't figure why the SAI monitor never became ready status, I finally got a BT OBD2 reader. This morning, I took some reading of the voltage from the O2 sensors on a cold start. Could someone here look at a graph and shed some light to my problem? Should the magenta (B2S2) voltage matches the green (B1S1) sensor? Anything else looks wrong in the graph?
