What in the hell happened at 6700rpms, did you just bounce off the rev limiter and not switch gears??

He must have Better check it is working from time to time

Log looks good. Great boost control! Try add some octane booster to see if that will clean up the timing (nothing to worry about though).

Right sorry, yes the log looks good aside from my initial reaction!

Try the 91 octane map also (running 93) and see how timing looks

Thanks for giving my graph a look. Hmm. Interesting that you commented on the boost control. This is actually an "After" log taken after installing two new mods on my stock turbo N55 EWG.

1) Pure Turbos N55 inlet pipe, enlarged the unboosted air inlet to the stock turbo by 42%
2) Turbosmart's new electronic N55 Blow Off Valve, plumb back version, replaced my stock Diverter Valve.

I thought that I had two good "Before" logs but the data was screwed up. I was attempting to see if I could reproduce data that another guy got when the addition of the Pure Turbos inlet increased his MAF reading from 5,000 RPMs and up.

I saved labor costs by installing both parts at the same time so this whole thing isn't a perfectly designed scientific experiment. I am getting MAF values up to 46 which is higher than he got. He was trying to estimate added horsepower from increased MAF numbers. Not sure how valid that assumption is. Tough when you only have a butt dyno!

My car is running very powerfully with an obvious decrease in low end turbo lag and an obvious increase in horsepower and torque. The engine just feels like it has power all of the time. Pretty cool!
I was hoping to have some real data to share but I'll be writing it all up and posting with photos over the next couple of days.

Do you have a link to the one you are using?


I jut don't see one for a EWG N55

I got it from Kies Motorsports. Bryan did an amazing job installing it on my 2015 335ix N55 EWG. There are two N55 models with links below.

Plumb Back Model which is quieter
https://www.kiesmotorsports.com/prod...30992487317589

Dual Port Model which puts out a whoosh sound when it opens
https://www.kiesmotorsports.com/prod...30992358899797

It is a huge upgrade. Rather than dumping all of the boost like the stock Diverter Valve, the Turbosmart electronic Blow Off Valve is more intelligent which eliminates a lot of the turbo lag. So great to step on the accelerator and get instant response.

I wonder if they make one for the PWG... on their website even the ones for the e92 N55 have a harness like it's electric, but I don't think it should :

I need to double check later when I have a chance but I think it works on PWG and EWG N55 engines. Remember those are both different waste gates for the N55. But I'm pretty sure they both use the same stock N55 diverter valve.

How does this increase turbo response? The diverter valve is there to bleed of pressure when throttle is closed.

I'm not a guru on this but my understanding is that the stock diverter valve in certain situations dumps too much pressure. Subsequently when you step on the gas it has to build back up causing a delayed response/turbo lag.

The Turbosmart bleeds pressure down to a safe level but maintains pressure so it's right there when you step on the gas. I don't know if I did the explanation justice but it absolutely works. Bryan and I both test drove the car right after the installation and the difference was obvious. It's a blast to drive.
