I removed it so I could get to the wires I ran through the firewall. After taking it off and figuring out what it did, I just didn't feel like putting it back on.

I'm not too worried about the cats later down the road because they will be gone soon anyway...

PS - still no problems noted and no CEL

I don't think it had to do with "tampering" with emissions equipment as obviously removing cats is a much bigger thing.

I also don't think your cats will be gummed up anymore (previous year STI's didn't have these) it's more of a jumpstart to boosting the emissions systems effectiveness prior to the cats reaching ideal temps.

I'm not sure if dealers would have block of plates as (AFAIK) the sti's had different heads and, as such, wouldn't have the port for the air pump valve inlet machined into them. If Dave starts a group buy you can count me in.

It would be cool to someone use this pump to spool the turbo (maybe not all the way, but a little bit).

Could be. I'm going to see if I can't find that part and a cost.

Nope. That's the cover to access the wristpin for cylinder 4.

Besides, those diagrams are showing the block, not the heads.

Well - so far about 50 miles driven with numerous stops and so far everything seems fine. Still no CEL.

Banish,
Did you remove the entire air pump emissions assembly, or just the physical pump itself? Look at the pic below:



I'm going to venture a guess and say that you didn't remove the large valvles or any of the other tubing right? If you did, you should have gotten a cel because the valves are no longer sending a position feedback signal.

Just the pump itself...

I finally did throw a CEL today (but it happened during a bunch of other "electrical problems" when I was wiring up my gauges).

Long story short - autozone pulled the code for me was "0140" IIRC said something like "secondary air injection system". Anyway, after more work on the electrical problems - including disconnecting the battery, the CEL is gone. I will let you all know if it comes back.

Pump is back in the car and the CEL is gone at this point. Unless I or someone else can figure out a way to permanently get rid of that CEL it's just now worth the bother...

I believe uncle scotty said the AP can delete this cel, but I'm not positive. I'll have to e-mail Cobb.

Just a heads up- a little birdie told me that Buschur is planning to produce the block off plates.

If by a little birdie you mean David Buschur in his thread...then yeah, I heard it from a little birdie too!

I e-mailed cobb but haven't heard back from them, I might have to whip out the cell and give them a call.

When I had a 06 swap done in my 2000 RS by East Coast Swappers (their first one) they didn't know where they would mount that and said that it wouldn't do any harm but they would have to take out the CEL after removing it. Ive put about 2k miles on it so far with no problems. But again they did open ECU tune the car befor I got it back. So I wont ever get a CEL from it.

i'd love to get rid of it, its the perfect spot for an IC sprayer tank! Just use a washer tank from an older WRX that had it there instead of in the fender..voila!
When it tripped the CEL did it effect performance at all? In VW's the later model VR6 motors had these damn contraptions. I just unplugged mine at one point as the ducting had developed cracks and the pump was really loud and triggering randomly. I never noticed a change in performance or limp mode charactoristics, I even dyno'd the car a few times on different chips and the A/F ratio was still right for that chip.
The way around it is to measure the resistance across the air pump, wire in a resitor of the correct value and the ECU will still think its there, unless it trips the catylist inefficiency code since it wont warm up in the spec'd time in the code. Its gonna be a bit og a chase to find the right ways but if you can get it down to a catr code, the AP or ecu tunners can just turn off the cell for that.

We do have air pump delete plates, we had them laser cut and they are instock now. We can ship them immediately. No group buy needed, just call us or order them online.

I hate these pumps, they are pointless unless your at high altitude.

Is this the same setup for the 07 STI?
I do not think so becuase I just took mine off and I only see the right hand side of the pic above..
