    R.G. replied to a thread Possible Custom Catchcan in N54
    9 out of 10 times when a single is smoking it's just the drain line. Even if it's not kinked, just making sure it's positioned with a good gravity flow route can make a difference. Might just need a small adjustment. Yes keep vacuum at idle. I believe mishimoto has a good double catchcan.

    Lpfp is dropping to 50s so it wouldn't be a bad idea to switch to e40.

    I can try, but the problem is that I can't log as the car misfires and turns off.

    Nevermind, bench flash. That's ok, it's something. About time to start flashing these cars!

    I'm looking for someone to coordinate from the N54 side. V8Bait you want to? It would at least help if someone knew a bit about tuning and has used the software in the past.

    There is a lot of intake manifold talk on the BimmerBoost forums as of late but there is little in the way of concrete results showing an increase in flow with aftermarket manifolds. EOS (Evolution of Speed) has some results to share with their V2 N54 manifold on a single turbo car. It is important to note that this car makes over 500 horsepower to the wheels with the factory manifold. For N54 owners to see gains they will have to be making a bit of power as the factory manifold is not a huge restriction. At 22 psi of boost the baseline shows 524 wheel horsepower and 515 lb-ft of torque at the wheels. You will note the factory baseline (red) produces substantially more torque from 3000 to 4500 rpm. With the EOS manifold you see a gain in peak horsepower but a drop in peak torque. The EOS manifold is showing an advantage from 5500 rpm until redline which is what produces a gain of 25 peak horsepower. The torque figure drops to 486 at the wheels however. Is it worth giving up some mid-range for top end pull? That depends on the application and goals. More testing is definitely needed on various N54 applications before reaching any definitive conclusions just yet.

    It's a VERY expensive goal. Not many people are willing to sink over 20+ grand into an engine. And that's not including the rest of the car upgrades to handle that power.

    I too think the crankcase prefers a bit of vacuum. My car was smoking lightly and consuming oil. I externalized the vacuum side of the PCV system and it went away. I'm guessing the little ports in the head or valve cover became clogged. I forgot what the BMW spec is for crankcase vacuum, but it's not very much, somewhere around 0.5 psi.

    Before you take any bits off your car, post a jb4 log so that I (and anyone else who wants to) can take a look at it. I used to get misfires on the E85 flash. In my case it was from running too much advance for the quality of the fuel we had here in England. I was using 93 and meth and some ethanol. Problem is here ethanol is twice the cost of 93, not avilable at the pump and cost something like $13 a gallon. I forget the exact number. Anyway a log can provide clues. Often when one cylinder badly misfires it sets off the whole bank which makes sense with the afrs and trims etc being per bank. It can't tell F'k all apart from ion detection of which cylinder started it all off.

    I'm having some custom work done to my block to strengthen it so any new upgraded parts that would/could help in that area is always a must in my engine. As you can see by my sig pic of my engine bay, i've had alot of custom work done.

    Thank you i really appreciate it. I will definitely check out the torque limit maps and see if it helps I'm on i8a0s but I will definitely try it. yeah I'm new to this platform I don't either like the feeling of running 13afrs when hitting that high of a boost even if it richens out when the power comes, but on these DI engines it looks like people are running pretty lean afrs on ethanol mixes under spool and also when hitting full boost. I will rescale the fuel when it gets a litle bit warmer so I can step up to a e40 mix and maybe get a few new good logs, abit risky here now with the snow and cold temperatures. But the car feels so strong, pulls very hard. I love that the boost is always there, a big difference from my GT47 Supra that I have been building on and abusing for years, still these n54 cars are so damn fun to drive. big thanks for taking the time and review my log

    This was sent to me from where I purchased injectors. I agree that more fuel is going to cylinders 1-3 but changing the injectors will not fix the issue the reason I say this is that Injectors fail in a specific way which I do not think this is the case and also we have many of these cases and usually it points to the turbo problem perhaps not being sealed properly however in your case it could many number of things. Your issue could be with the DME, air fuel ratio (leak) or the turbo. To test this simply switch one or all injector from cylinders 1-3 to 4 -6. You will see that you will have wet spark plugs thru injectors 1-3 and not 4-6. Your DME is getting the wrong air fuel reading which is compensating by giving a lean fuel ratio to cylinder 1-3. You had much work done so it could be anything but I would first look at the Turbo and Vacuum hoses responsible for cylinders 1-3.

    This looks like another way to test for leaky injectors As well as the deceleration test, watching afr across bank 1 and 2. In gear at say 50, decelerate, ensure both banks exceed 200 when warm and follow each other. Also if you're DIY inclined, and want to swap the injectors, here's how to change the seals

    Are you certain that your WC73 doesn't have a MSD81 DME? I'm fairly certain that all WC73s had a MSD81.
