So I have been thinking of this and would you agreed that this would be a hardware issue and not a boost leak ? I am thinking along the lines of a wastegate / turbo issue and not a leak since I am able to get to target boost. Just slow to build.

Hard to say for sure. You'd need to perform the boost leak check and verify the wastegates. Those should close with approx. 7 in of vacuum.

Hello Guys, so did some investigation and noticed that menu 12 was set to 1500 rpm. So I adjusted it to the default 2800 and here are the logs. I know what I still have to do the leak tests and check the wastegates (vacuum is good based on the test with the jb4) . But now boost is hitting the target earlier.

But let me know if things are improving. Duty basis was set to 65 to 5500 / 60 then 55 for the rest.

Also is there something to be said when the car is build target boost so linear ? Most default patterns don't look like that and more of a spike.

Still has an issue...that is still building boost really slow.

Thanks. Would you say these logs are a step in the right direction? I know boost is building slowly but making manual adjustment to the rear wastegate resulted in the following all else remained the same.

No. It's a much bigger problem. You won't chip away at this one.

Agreed and you caught me

But last night I think i found the issue. I put vacuum to each of the boost solenoids off the top of the vacuum canisters and they are both not holding. Based on my readings they should. The next step is to do the test with the gauge in the window in 3rd and WOT but I was looking for a way to compare each.

Replace the vac lines, cheap, and prone to failure. Inspect canisters for cracks. Bet that fixes your problem.

Yup did the lines behind the oil filter but also did the vacuum test as per the youtube vid with and vacccum is fine. This is why I am looking else where.

So this is what I got doing the JB4 Vacuum test -

on 60 % - 17" vacuum
on 100 & 29" vacuum
on 0% - 0 vacuum

Based on this wouldn't you say I don't have a vacuum issue ?

Ok I need some direction here.

So I tested the wastegates as per the directions and was not able to pull 7" basically I ran out of room on the pump and was only able to hold 4". As I was applying vacuum nothing happened until i got to the top. But it did hold at 4".

On another 335 I was able to pull and hold vacuum on each of the lines at the top of the canisters but on mine it bleeds off. Both tests were done with the cars switched off.

On my boost solenoids with the out capped they both bleed off vacuum slowly as expected. Tested another pair and they did the same.

Based on the JB4 test I don't have a vacuum leak

Now based on the test i did on the other 335i I don't under stand why each of the lines on top the canisters held vacuum when mine did not and this is where I am puzzled.

Could have a leak in the canister. Pull them and test them separately. Then test the out lines from the canisters to the wastegate.

So when I say I tested from the lines on the top of the canister I mean I pull it off and applied vacuum. So on the other car it held and on mine it bleed off. This line is going to the vacuum side of the boost control solenoids. When I tested the wastegates they held 4".

So your hinting to the line going from the top of the canister to the solenoids ?

Sorry, I thought you applied vac to the canisters through the top port, which would test canisters and wastegate lInes from canisters. The plastic canisters have cracked from time to time. And I was trying to rule them out.

Running out of ideas myself without being there.

Thanks for the support. I really thought I had it at the solenoids. So far people with this issue have solved it by the following -

Wastegate adjustment
Removing the secondary cats
Boost control solenoids
And unfortunately replacing the turbos

However the fact that my FF is high and duty basis at 65 for me to hit the targets after the spooling issue does that add any further information to assist with trouble shooting ?

Hey guys can I bypass the boost control solenoids with a vacuum connector as a test ? So bypass and take it to 5000 rpm to see ?

Hey Guys, So can I safely bypass the soleniods and send full vacuum to the wastegates ?

Thinking to try this and just run the car to 5K and back off.
