Hey M
Are you basing this off of new info since we last chatted? I'm still getting Not Ready for my SA monitor.

Do you mind sharing more details?
On a stock tune do you pull a SA error code and a SES light? If you pull an error code on stock, and if those codes are now gone with your edit, do you have a scanner to confirm if the monitor shows as Ready or Not Ready? I followed this thread which disables the SA pump altogether.
I have no SES or error code but I still get a Not Ready, the pump doesn't turn on at all on cold starts. How do you delete the fault code without fully disabling the pump and deactivating the emission ready status?

OP as far as I know, the DIY method commonly referred to deletes the error code and SES, but shows as Not Ready. Sounds like this will work just fine for you in your state. And for those of us with emissions, any guidance for coding a Ready status would be extremely helpful.

Sure, let me look today and take some screen shots of my Emissions Readiness. I could be wrong about the readiness status - admittedly it's not something I keep an eye on at all since it doesn't really matter here but, I'll post back later this morning with some more concrete info.

Screen shot of my emissions readiness. My car would trigger the AA code (low secondary air flow) occasionally, so I suspect my blockage is on the threshold of the system's tolerance. I selected CA Emissions standard for 2000+ gas powered vehicles, which I assume is correct. The red Xs represent monitors which aren't applicable to our cars.

All I did was delete the AA code from the program space, which is what p0lar has described in this thread: DTC (OBD Error Code) Deletion/Removal Strategy - BMW M3 Forum.com (E30 M3 | E36 M3 | E46 M3 | E92 M3 | F80/X)

Sorry, I haven't had a chance to jack around with this. Been interviewing, but should have time on the weekend to reflash and see how long it takes to set ready...

Thanks for the screenshot Rontgen. I wonder if your pump / ports being on the verge of failure is the reason why it shows as ready. Mine gets the SA trouble code reliably, and so far when I've coded it out I've come up with Not Ready.

So I'm guessing you used a hex editor and not the MSS52 Bin Mod Tool ($30)? Thanks for the link, there are 4 methods there, which one did you use?

No worries at all. I was just wondering if you learned something new because from my own experience, getting the SA to show Ready hasn't been straightforward yet.

You're welcome! That's a good point - my car may not be the ideal test mule since it didn't reliably trigger the AA code. However, further down in that DTC deletion thread, it does talk about emissions readiness and it sounds like others have had luck with getting a ready status.

I did use a Hex tool, but the Bin Mod Tool wasn't available at the time. Nowadays, I think the few dollars for the Bin Mod Tool is well worth it.

I don't have my garage laptop with me right now, so I can't verify for sure but I believe I used the first method. It sounds like others have had luck with the method hat zeros everything out.

Best of luck!

In the FWIW department, Wiki indicates two benefits of secondary air injection. One is for helping burn the rich exhaust during open loop at cold startup. This is typically done with air injection upstream, at the exhaust ports, as is the case with the S62.
The other use is for aiding in the catalytic conversion process during normal running and is usually done with air injection downstream just in front of the cats (as with Sailor's reroute).
Thing is, the way the ECU is programmed, the pump only runs at cold startup. So injecting air downstream will likely only minimally aid in burning the rich exhaust at startup. The main benefit I see would be getting rid of the AA code.
Obviously it would be much easier to just code it out.

Bringing back an old thread rather than starting a new one. ... I figure anyone knowledgeable on the system will be here anyway.

I have built myself a SAP Simulator and have been driving a couple days... No pending codes, no CEL.... but the monitor has not cleared yet. The SAP triggers on cold start but (lovely Los Angeles) that has never been below 75* ambient temp.

I have read that the system can throw a fault on a cold start but needs a COLD start (60* or less ambient and coolant?) to pass the monitor... does anyone know this to be the case?

The reason I am trying this route is that I have spoken to 2 different smog techs saying if they see an "unavailable" SAP monitor with a SAP on the emissions diagram its an automatic fail.

Thanks in advance.

Just code the monitor out so it's always ready and be done with it. You'll need to leave the SAP hardware in place if you want to pass visual though...
