I know this is not an E60 forum but you guys are so responsive...hoping that someone out there is a 535i driver and cant explain or show me some reference online that would explain how to get my vacuum lines back to stock.

Take a picture of your current set up. I've never looked under the hood of a 5. If it's the N54 motor it shouldnt be too different than what we have in the 3.

The t- hookup is closest to the front of the car and the single hose is closest to the rear of the car is the best description i can give

single hose < T hose> is the stock for the soleniod back to stock

[hotrod182]

Are you talking about the boost solenoid hoses? Well, here is a picture of the stock ones on my 07 335i. Maybe that will help?

[cn555ic]

yes thats it for stock!! should be the same for 535

Here are some shots under my hood....I know I am making this more difficult than it is so hoping someone can point me in the right direction....

It seems to be different.

[NPDAN]

It does seem to be different. Where are the original hookup's?

I have no idea...that is part of my problem.

This is where you're solenoids are.
In the third picture remove the coupler.
There should be a solenoid near by with two outlets for vacuum, just place those two vacuum lines in the solenoid.

Y are you putting it to stock?

I just installed V2. I haven't changed a thing with my vacuum lines.....ran fine up the road just now.....are you sure they werent already stock?

What part is the actual solenoid that is supposed to have two open connections for these two lines to go back to?

[cn555ic]

You should make sure you place the solenoids back to stock because V2 requires both and no bypass of the boost selonoids...

Well, that's what I'm trying to do. I can't figure out how to get them back to stock.

[cn555ic]

Running the Procede V2 with them still bypassed i think is not a good thing, so i hope you can find someone to help you out...You can drive it, but don't go nuts and go WOT until they are back to stock

[G33]

wat does this solenoid thing do anyway? cos i also had to do this with jb2

Will I be able to tell a difference once they are back to stock? Feels pretty good now.......Sure would like a pic from a 535 owner or some reference to a parts catalog....

[yahtzee]

I finally figured it out (thanks partially to 1BAD535). I have attached a pic showing what they looked like during 1.47 and also a pic of what they look like during V2 (back to stock). Hopefully, this will help the 535 owners in the future as the setup is different than the 535.

#1 on the first corresponds to where #1 should go on the second pic.
#2 on the first corresponds to where #2 should go on the second pic (you basically point the #2 tube back towards the ground)

It helps trick the ECU in to thinking you are running the stock boost levels.

[G33]

good stuff terry

ive installed the H quite quickly yesterday without breaking anything luckily! i havent had a chance to thrash it out yet tho but no problems so far!!! approx. how much bhp do u think it will be pushing out now? i think i will get a decent dyno done in a few weeks

to expand on terry's response...


basically if you run more boost, the ecu sees excessive duty cycle on the solenoids, and knows that something up... bypassing one of them basically makes the ecu think that you are only using stock or less boost, because the duty cycle is effectively halved because the one solenoid doesnt get boost, and the ecu logic averages the solenoid duty cycle between the 2.

This is how I understood it...

If the octane level is there you should put out 340-350 rwhp! More than enough to spin the tires.
