Earlier this week I finally decided it was time to pull my intake manifold and send my DME to Alex MissionPerformance I pulled it out Monday night, and FedEx overnighted it to Alex for Weds arrival. Alex got it flashed and overnighted it back to me Thursday, and it showed up yesterday.



This morning I bolted it back to the intake manifold, and reinstalled it in the car.



While I was in here I decided to go ahead and install the FTP charge pipe and AFE intake that I bought.

The FTP charge pipe fit great once I got it in position, but it was unreasonably difficult to get the oring on the throttle body flange to snap over the throttle body flange and into place. I ended up having to take the throttle body off the intake manifold, place it on my tool box and bear my full body weight down onto while rocking the charge pipe side to side before it finally pressed over the lip and down into place. No way that puppy is leaking anyway!

The AFE intake was much more straight forward, although for the price of the thing I'm really not impressed with the fit, finish or overall quality. It looks nice installed however, and whatever gains it actually provides may be nice... but some things about it I just don't like.



With everything buttoned up I took the car for a test drive. Even driving gingerly in comfort mode until the oil was up to full operating temp I could feel the difference.

Once it came up to temp I kicked it into Sport+ mode. Available torque upon request when buried behind gearing chugging along in 7th or 8th is really most impressive. A gentle tip of the throttle and without even downshifting the torque Sport Display that Alex rescalled instantly jumps to 300-350 and then rolls up to 400. Before you realize it you're going way too fast, all the while tolling along at ~2000rpm.

From a dead standstill there is still a delay as the turbo spools, then it wails you back in the seat, the 285mm Michelins screeching for a foot hold against the asphalt. This is easily negated by taking off from a standstill in Launch mode at ~2500RPM or so which spools the turbo for a neck snapping jump off the line.

Its hard to quantify just how much quicker the car is at this point, but its definitely there. The low end grunt is awesome.

I'm hopefully sending a core turbo unit off to Pure in the next week or two, when that gets back I'll toss that in and it should carry that low end grunt further through the RPM range.

Crickets up in hurr....

This evening I got to thinking and decided I wanted to take the car our for a cool(ish) evening run. I also thought that it might be interesting to see how the car would take to an E85 blend.

I checked the cluster for the exact fuel tank liters and then ran the math for how much E85 I had to add to the tank to net E30.... they went to the nearest station I know with E85 to do it.



I know I mentioned that Alex rescaled the Sport Displays, but in doing so it also bumped up the scaling on the 6WB Kombi as well. Nice. From 320HP to 400HP.




I never asked Alex how the tune would work with E30, but it seems to respond well. I drove chill for about 5 miles in comfort by even with the slightest tip of the throttle the car wanted to take off and the Torque Sport Display rapped out.

After those 5 miles I decided the fuel should be adequately blended from sloshing in the tank, and run into the lines.

The car pulls so damn hard in 1st now, and punches you in the chest back against the seat into 2nd. Amazing what just a little more octane will do. This is my first experience with corn juice and I have to say verrrrryyyyynnniiiiccee.

I had a hard time taking a picture of the Sport Displays under load, this was the only picture that came out. The Horsepower gauge peaks at about 380-390HP, a bit higher than indicated, and the Torque gauge pegs out and stays there now.

i drive with his stage 1 tune on 93 octane im also a fan, you'll get mostly crickets here until after the holiday weekend

Yeah man were all drunk right now it's hard to type hence the crickets, hahaha. Very nice review. E85 made a difference for me too especially mid range-top end. I wish you had more seat time with the tune and then put the AFE filter on. Curious about the difference. Anyway, the turbo internal rebuild is my next step too. Talk to Alex about that he too is working on offering turbo rebuilds for our setups. Might save yourself a few grand

Welcome to the club of the fastest F10 535's prowling the street!

Btw sick cluster!

Lag off the line is because of a few things and Alex can correct me if I'm wrong. He's moved the available torque a little higher up the rpm band to save your trans. I've found that the sprint booster corrects that "lag", but you can ask Alex to increase throttle sensitivity. I like toggling my SB on/off even though it lives in performance mode most of the time.

The shop I work for setup with Pure recently, and we are going to send some turbos from various BMW's in for rebuild soon anyway. Tossing my core F10 unit with them should be pretty cost effective. My thoughts are that the Pure Stage 1 turbo should give me the power I'm finding with E30, on just 93.

Curious how much blended E85 you've run on your tune Bmw doubles

I don't think its prudent to exceed E30 on the stock LPFP from what I've read.

The lag I'm talking about from a dead stop/idle doesn't seem different in any way from how the car performed with factory software. There is no boost being made idling at a red light. You have to bring the RPM's up to 2-2500RPM for party time. That is pretty much what Launch Control does. It hangs the RPM's right into maximum torque zone and then rockets off when you lift off the brake.

[Bmw doubles]

I've done 5 gallons in my 19 gallon tank.

[Stück]

Our tanks are 18.5g AFAIK.

You have 91 in your neck of the woods yes?

13.5g 91 and 5g E85 is E30.3 by my math.

[Bmw doubles]

91 is the dirt we have, yes

[paul223]

I saw your thread how you built this car, simply amazing. Now waiting for pure turbo upgrade.

[PJinCA]

mission performance tune is definitely on my mod list. my only debate right now is whether to do it now, or wait until after the pure turbo upgrade.

Now then flash remote tune again after the turbo upgrade, then more time at the Dyno with Alex. Then you'll get all experiences

[Secret_Asian]

I would say do it now and enjoy it. It might make you decide to skip the turbo upgrade depending on how much performance your after. Then if you do go pure turbo with mboot alex can remote flash it

[FSociety]

Stuck are you going to Dyno to see your gains?

[DigitalNav]

Is it save to mix the 5G of E85 in a non-modified fuel line car?

I have a racechip ultimate and only get 91 octane around here. Was curious how this mix would help the car?

[Stück]

I am going to try to dyno the vehicle to get an idea of where it is now before I install the Pure Stage1 turbo, ER Downpipe, and Mission Performance Stage2 tune... then go back to the same dyno for an after.

I saw Bmw doubles using DashCommand on his thread, so I thought I'd do the same. Here is what I'm seeing on 93/E85 blend.



I'm running a ~E30 blend all the time now. I found that for whatever reason I was having detonation even with 93 octane on the tune. I did some real time data logging and saw the DME was pulling timing through the turbos efficiency range, often times severely. I mistook it as spark blowout initially but even after gapping the plugs down it didn't go away.

Putting some E85 in the tank eliminates the problem, and the DME gives me nice timing advance throughout the RPM range now. The car is night and day different on 93 vs. E85 blend (~E30)

My car is perfectly happy with net E30. It has no issues and lots more power. Only downside is cold start is lumpy for the first minute or so as E85 is harder to burn when cold. It clears up quickly though, not really an issue.

You can start low adding 3 gals of e85 + rest 91, only Flash Tuned or JB4 cars can take advantage of more e85 as there's a tune in place for it.

You don't need modified fuel-line btw not until you want to run high mixtures then you will need Stage2 Fuel Pump from Fuel-It and Port-Injection if u want big power and 100% e85

Interesting it's not working well on 93. E85 is always great for correcting detonation. Remember adding more air is an important factor on a tune. I found that the custom air filter I added helped with breathing and overall feel of the tune. More power up top for sure and less stumbling feel on cold start. Nice 16psi!

Would love to see your car on the dyno if you'll be dyno'ing locally! Awesome build man, I've been craving e85 since I had it on my STi and the difference was unbelievable. I can only imagine what it's like in the 5er with other bolt ons, looking forward to the Pure turbo upgrade as well!

[DigitalNav]

Havent seen anyone running a PURE turbo on the 535i yet. Im interested!

Do you do anything special to configure this app tp show correct HP and Torque?

[FSociety]

DashCommand reads Crank and not 100% accurate unless you got every seting filled in
I feel TorquePro is much more accurate reading at the wheels or crank and requires less settings but those settings it asks for its Good ones

Take these readings with a grain of salt guys
Best investment you'll ever do whether stock or tune is going to a Dynojet or/and 1/4 mile to compare your times/tune.

Dynojet for the win because you can get the DRF files onto your usb, take it home, open it up on free WinPep7 or preferably WinPep8 (new version) and view your runs, see how much u making at different rpms etc.. Then go fix or get a new tune and DJ again get your drf files and see it at your comfort the before/after.

[Bmw doubles]

True dashcommand hp and tq settings are off, but we did confirm psi, maf and coolant reading were pretty accurate. Torque pro is EngineLink on iOS.
