REMEMBER.... ANY TAMPERING WITH FACTORY EMISSIONS SYSTEMS IS A VIOLATION OF FEDERAL AND STATE LAWS. PERFORM THIS AT YOUR OWN RISK There have been couple of threads lately http://volvospeed.com/vs_forum/index.php/topic/132158-sas-delete/page__hl__sas+delete and http://volvospeed.com/vs_forum/index.php/topic/139442-another-sas-delete-using-luckys-idea/ that have discussed ways to delete the SAS (air pump). I suggest you read them for background. This will be strictly a write up of 2 ways to accomplish this. This has been a joint effort with Volvospeed members IPD-Lucky and Flaco both contributing to this mod and obviously they both deserve a lot of the credit. It appears that a diode (Radio Shack #1N4003) connected between pins A32 and A37 of the ECU will cause the ECU to "think" that the airpump system is fully operational. The only parts of the airpump system you need to LEAVE installed are the airpump relay and the solenoid valve. They both need to have there connectors connected. Everything else can be removed. Here is a picture of the scematic showing what we are doing, notice the direction of the diode, that is important.... The mod can been done one of two ways. Either inside the ECU or in the harness directly below the ECU. To do the wiring IN THE HARNESS UNDER THE ECU, first you need to prepare the diode (radio shack #1N4003). I soldered it to a short section of wire.... Then attach a section of heat shrink to protect it and mark the direction that the current flows.... .... Then remove the ECU and the plastic housing.... Then you can access the harness and install the diode between A32 (GN-SB wire) and A37 (BL-P wire). DO NOT cut either of the wires. You can install the diode with a Scotch-Lock or the way I did it was to just slice away some of the insulation from the wire and solder the diode to it. Then I taped up the soldered connection. Just make sure the diode is pointing in the right direction.... Put it back together and that's it. I like doing it this way so the mod stays with the car, even if you swap ECU's. I would get a little nervous opening up a stage 3 IPD ECU that I just bought, to do it inside. Wouldn't want to chance screwing that up! To do the wiring INSIDE THE ECU, first remove the ECU and open it up. Bend the 4 little tabs up. Then swing the hold down lever around and out of the way. You may need to pry it up slightly to do this.... Once you're inside it's very simple, just find A32 and A37 and solder the diode in place. Again make sure the diode is pointing in the right direction.... Secure the cover and re-install the ECU in the car. That's it! I have one car with the wiring done under the ECU and one car with it done inside the ECU. They have only been done for a short time so I guess we'll say it's experimental at this point. The mod in this thread http://volvospeed.com/vs_forum/index.php/topic/139442-another-sas-delete-using-luckys-idea/ was on my car for well over a month with no CEL. So it can also be done that way.

Chilledman 2 days for niggerrich comment.

:lol: When he blows out his cigar smoke. I was in tears.

Has anybody checked the status of secondary air system readiness with a code scanner after doing this mod?

this racism is killling me inside.... http://www.youtube.com/watch?v=oKd35EmCIx8

Reinstatement of don't ask don't tell a deal killer huh? I'd want the world to know If I putted from the rough as well ...

Your not an american citizen you dont get american citizen rights. Not sure whats hard to understand there ? If we could we should be waterboarding every illegal that enters this country :lol:

When can we expect Obama to apologize?

There is no hope for you.

I think they're the best part. :unsure:

Dude, you ARE the Taliban.

they just won't leave me alone. I try to make my own decisions and pay my own bills and apparently that isn't enough to make them happy. They won't wean me off of their dependency they just want it cut and dry and its screwing me over so hard right now. I have to make the choice of paying a student loan bill or car insurance I need to get out of here and make my own choices. Also I may not be going into the military anymore.....

REMOVED POST: I read the latest on the TDR topic... I was just about to install a low-pass filter on the solenoid PWM wiring to activate the diode but this works a lot better haha good work Volvo5.0 I will edit my last how-to to point to this topic. and P.S. I wasnt trying to get credit for your work when I said I would do a write up. I was just trying to help... Update: Switched the diode over, so far it works. System runs on first start and no direct codes. Now I have to find a exhaust cap.

I want to kill my parents they never mind their own business and I'm so damn sick of it. Next paycheck I'm moving out of this place

100% pure E-Penistry and nothing more. Buying a set of wheels and putting them on a car that is worth less then the wheels is flat out justinrich and nothing more nothing less. It shows the flat out stupidty of the person involved. Hey look at my escalade and my 5k wheels but I live in the ghetto and dont pay rent . There competeing for levels of stupidty

but......I want the cookie.....

kinda hope not....

aw Justin so glad you care about Cougars more than me! :lol:

still banned from chat :( :(
