Eleventeen, where did you mount the MAF sensor on the new intake you made?

It would definitely fit an xi model, but the DP would probably be in the way of a RHD model.

The N54 only uses a map sensor which is located on the charge pipe. Fortunately, there are no MAF sensors to worry about.

Right now I'm still monkeying around with the tuning. I'm currently running it flash only which requires more work to get it running right. At the moment, I have to figure out how to get rid of the throttle closures that the JB4 is good at buffering. The DME is very sensitive to over boost (anything more than ~1psi over boost causes major closures). I found the table that should adjust this, but haven't had much time to mess with it. I think / hope I just need to lower the values on the upper end of the table.

Once I have the flash all dialed in, I will probably have to go right back to the JB4 / flash setup due to the 18.5 psi boost limit that exists running the flash tune (unless Cobb can raise this somehow). Regardless, I want to see what's possible with flash only tuning and it's good practice for me using ATR.

Okay, it turns out I had to raise the values in the table called Throttle Angle Aggression In Overload (for those familiar with ATR). I tried this previously, but I guess I didn't raise them high enough before. The throttle closures are very minimal and boost is staying right on target.

Also, I found another option to running the OEM BMW solenoids. In the one or two logs I took I didn't see any functional advantage over the OEM solenoid; but the larger hoses required for an external wastegate fit better. It is almost identical to the BMW OEM solenoid, but it is actually an Audi / VW OEM part. The reason I wanted to try it is because the inlet and outlet nipples are the same size, so the hose has less chance of slipping off. It is a bit pricey, but you can find it much cheaper than the link below if you look around. The duty cycle in the before and after logs look identical, so the nipples seem to be the only difference.

Bump - did you ever figure out the misfire issue you were having?

You have the nicest custom kit. I want more pics.

Also, please excuse my TIG welding "skills"; until about 2 months ago, I had never tigged anything.

So... I like the manifold... Will you make me one? How much?

I never found a mechanical weakness that was causing this (even after a compression and leakdown test). If there was an actual misfire, I suppose it could have been a fueling issue due to maxing out trims. If so, the backend flash probably took care of that. Regardless, I turned off the misfire detection since I never noticed any actual evidence of a legitimate misfire (the DME seems to be overly sensitive). The car dynoed 570 whp on 93 & meth through the stock exhaust, so I believe it's running fine.

I built a custom intake, but I don't really like the potential added restriction or the zero hood clearance it provides. I just run a K&N right on the turbo (I believe it's the same filter they run on the FFTEC kits).

Haha, it took me forever. Now I see why they cost so much! Unfortunately, I wouldn't have the time to build more (unless that was my only job). The FFTEC kit is really nice and they sell the parts separately now. It's worth checking that out. That is probably the route I would have gone if they sold the manifold by itself a year ago.
