Related question - for those of us that want to completely remove the SAI components, do we remove everything in the diagram below, or do any of the items need to be retained? If the latter, which numbers?

I replied in the affirmative fairly early on so I hope I don't get lost in the shuffle. Looking forward to using the part.

I'm just waiting on some numbers from Gelbster before I send any out. Hopefully will be soon.


Thanks - its not a rush, if I'm on the SAI list then all good. Now get to work on the post 02 sensor unit

I had SAI codes and a "Ready Status" Fail flag so my car failed the Test-Only California Smog Test. I completed a tedious project to trace,check, repair and upgrade the entire system. Not a simple weekend task !
I fixed it all and passed Smog 5 days ago.During this honeymoon period I disconnected & plugged the SAI pump hose to simulate a failure, connected the Particlewave circuit to test it. It worked. I then disconnected it and reconnected the SAI hose.No codes. This morning the codes came back !
Knowing this may be an endless cycle of failures/fixes is not attractive.
This is why the circuit from Particlewave is useful to me. I can just fit his circuit now, delete the CEL with a simple code reader and repair the SAI system(again) when I have time .
For those curious about the SAI vacuum upgrades I made - most of the vacuum connectors are now brass and the hose is good quality 3mm silicone.Should outlast the car -& me ! I also rebuilt the SAI pump and have a rebuilt spare. TheSAI pump still operates perfectly - I can hear it.The vacuum system which is easy to test(but tedious to fix) still holds perfect vacuum. So it is probably the electric change-over valve, or.......
For the Durametric users - if you are looking for the pre-cat O2 Sensor voltage to prove that the air injection system is working/failing - remember two things
1. The ports in the cylinder head can plug with carbon(mine is a newly rebuilt M96 so no problem.
2. To see the graph of the flat wave form change to sine wave(the proof) on the pre-cat sensor - start the car at the coldest possible temperature and be really fast with your keyboard skills.At Los Angeles summer temps you have no more than 5-10 seconds before the flat wave changes to sine wave in my experience. If you are slow you may make an incorrect diagnosis.
