Deleting Air Pump and Charcoal Canister (M60B30)

[MJCRO]

I need insight on deleting this emissions control air pump system and charcoal canister for the M60B30. So far, I've pulled off some of the components but there's some this stuff I'm not sure what to do with.

Here's a diagram from RealOEM showing the piping. Can I simply just delete all of this and plug the holes?









I do not plan on running a charcoal canister either since my engine bay is already cramped enough. In the picture below, on the left is the vent line that is supposed to go to the charcoal canister, on the right is a hose that originally went to the 530i brake booster. The motor runs fine with either left as is, but I'm curious on which to plug or where to route them.

In the last pic, they are both wide open to the intake manifold after the MAF, so they are vacuum leaks and need plugged. You can do just that, plug them. I put a rubber vacuum cap over the charcoal canister on mine as well. I still have a brake booster, but you can do the same thing there too.

You're going to have a check code stored in the DME at all times with the charcoal canister purge valve unplugged, but it won't hurt anything.

I'm not familiar with the air pump system, so I can't help with that.

Yep, deleted the air pump system with no issues.

Still working on capping these vent lines on the intake manifold, ordered a different ICV so hopefully that clears it up.

Battling this still...

Having trouble with deleting the charcoal canister and air pump system still from this motor, I'm thinking the ECU might have parameters governing how the computer should run without it hooked up.

Currently I'm running the engine with the vacuum control portion of the air pump system but when completely deleted, the engine goes into a kind of "limp" mode, causing the car to bog down when giving any harsh throttle during driving. But when connected, the car runs and throttles smoothly leading me to the conclusion that it is sensor related. Also my TPS, ICV, and MAF are working fine, but if I cap that vent line for the charcoal canister, the car won't run!

Shot MarkD an email to possibly shed some light on whether 404 DME's have something in them for emissions related stuff. Maybe I could get a chip to disable all this crap and run the car on the bare essentials with a performance map.

Update:

Fixed the issue. Reset the ECU with all the plugs capped. Started up perfectly and idles right now. Still surges a bit, but I still need to replace all the gaskets on intake manifold.

how did you reset the ecu, just disconnect it for five minutes?

[MJCRO]

Had it disconnected overnight to make sure. Also had my MAF flipped around the wrong way this entire time lol. I knew that air pump system and charcoal canister BS could be deleted from the beginning, just was paranoid that the B30 might've had some different design to it.
