ok, i want to removing the sai entiirely from my car.. im gettin trifecta to tune it out so i wanna know how to actually remove the unit itself.. any help would be great, thanks!

 

Remove it off the ECU

Then you can remove the unit off the exhaust manifold. Or you can leave it on there. Either way it is de activated.

 

yea, but what is it exactly.. just that tubing? or what?

 

yes..all it does is suck fresh air into the exhaust (the tube goes from the airbox to the exhaust manifold)

you could also plug the airbox or get an airbox that doesnt have SAI

 

On the 2.2 LAP it is not on the exhaust manifold and is a pain in the butt to remove. See my supercharged thread for the pain in the butt details.

 

I've ACTUALLY done it. First the pump is attached to your exhaust manifold, so only remove it if you have a replacement. Otherwise you will have a gaping hole in the side of the manifold. then follow the tubing around the driver side to the front of the block and underneath. there will be another part to unbolt. that is just holding onto the block so you can take it off without uncovering anything. you can cut the rubber tubing but i found the best way to get the metal tubing out is by removing the the driver side headlight.

that's pretty much it

 

By your signature you've done it with a 2006. The 2009 LAP has a totally different SAI setup. Again... read my thread.

The SAI is part of the cylinder head in the rear in the LAP. It is not the case in the L61 as it is on the header. I ran into this in my thread... I'll copy and paste the info....




Friend came over so we got to it. Started stripping things off the engine like the coils, fuel rail, etc. Started removing all of the SAI components. Removed the SAI tubing and switching from the back. Removed the exhaust manifold and down pipe. When we got the exhaust manifold and down pipe off we got a little surprise.

There is a tube connected to the back of my cylinder head that has open ports and the cylinder head has ports for this thing in the back!! This is not on any other year SAI vehicle except for my 2009!! Here is a picture of that tube in a diagram. I was going to take a photo but my friend put it back on before I could get to.







It looks like this when the manifold is bolted up...the holes in the gaskets show you where this tube goes on the back of the head.







I quickly realized that I may have to use the stock exhaust and leave the SAI tubing and switch in the back and wouldn't be able to use the LSJ exhaust manifold or down pipe. After sitting for a few minutes and thinking about it... I decided that I could probably modify the LSJ exhaust manifold to accept this tube.

This picture shows where those holes in the gasket to accept the tube should be on my LSJ exhaust maninfold.








So I took my red paint pen and outlined it on the LSJ exhaust manifold.







Here is the finished LSJ exhaust manifold ready to accept the SAI tube bolted to the back of the cyl head. Should have taken a different picture because it is showing black where I cut it out. It took me 1 1/2 hours of using my grinder, dremel with a diamond bit, etc, to get this to work.







The LSJ exhaust manifold and down pipe are now installed. My rear 02 sensor wouldn't come out of my pipe, so I have to buy a new one tomorrow. I also had to modify the LSJ exhaust manifold heat shield because it wouldn't fit because of that tube behind the cyl head.

 

****... this is gonna be alot harder then i thought...

 

can you post those pics again cant see them i wana put a header on my LAP with sai
