DYN-O-MITE Time !

So I woke up this pass Saturday morning decided to drive the m2 stop by Costco gas station filled up the tank and decided to visit European Auto Source to do a basic dyno. (Dynojet)
Here are the results on 91 octane (shitty gas from Costco )
we did three runs :
With the same result: 322-329
and the last three runs we decided to add 1 gallon of E85 octane
on 3/4 on 91oct
Result: 340-352

I guess that is not bad for 91 octane. My car did 350 whp + 417 ft-lbs on 93 octane on a dynojet as well...

Lol Mama Juana in the tank? You did a before and after pulls? Any Mangu in the tank also?

Those base numbers look good OP..

Has anyone tried any Sunoco 100 octane?

I'm planning to do a stock run on 91 octane and 100 octane with jb4 as soon as they have an open slop for me. Hoping this week

Costco is by far my fav gas for the past solid year.
Its the most consistent station to station gas brand I've used in my X3 and X4 M40i.
Heck, those are solid results for 91 and wow 439wtq with just 1 gallon of e85

They run lean from factory but an extra gallon of E85 won't make it much leaner that one should worry about.

What should the AFR be? What if you added two gallons of E85? Is that safe, without tuning. To raise 91 octane to 93. Thanks!

Here's a real world AFR example. 4th gear 3k-7k with e15 left over from last fillup. Mostly 93

The m2 actually runs a bit rich compared to other n55's. Normal is 12:5:1, the m2's stock tune dips into the 11's.

Most DI motors can be tuned safely to run mid 12's for AFR.

Thanks! Did you have any tunes or mods when you took that datalog?

Yes I have an Intake, catless DP and JB4 for logging. So my settings may be oscillating AFR's a bit but JB4 doesn't effect Lambda/AFR's directly. Just the fuel pressure sensor. I can do a log in map4 and will post to compare

Honestly I'm glad the m2 has thicker AFR's. A lot of times people running this setup on the m235i have scary lean AFR's considering the torque curve hits so hard, so quickly.

Does anyone on here have experience with the ECU psi going above the DME boost target?

Yes and this just about terrifies tuners that haven't tuned a di BMW or are used to a less sophisticated DME lol.

Thanks! I really appreciate it. Which downpipe and intake are you running? So the log you already posted, its on the stock map correct? Does the catless downpipe cause boost spikes or boost creep on the stock map?

Thanks!

I'm dealing with the ECU psi reading above the DME boost target. Could be due to the downpipe but I'm not sure. BMS I take running Mafless and VRSF downpipe.

The ECU psi could be causing throttle closures.

There's no MAF? You can do that??

How much higher PSI are you seeing? What's stock boost set at?

The maf on the n55 is for idle and low throttle emissions. The n54 doesn't use a maf. It's a JB4 option for people with lumpy idles due to the extra flow some intakes provide.

Wow that's good to know, thank you sir! Do you know if the Eventuri intake would cause that by any chance?

So under throttle what does the car use if it's not using the MAF?

I haven't heard if it does or doesn't. If they copied the factory flow it won't. The BMS I take flows a lot more so it causes little hiccups like that. I just like that it wasn't a factory clone.

Actually the DME BT and ECU psi aren't as far off as I thought. JB4 is probably just learning.

The factory DME targets up to 14-15.5psi I believe. Hangs in the 11-12 range most of the time

Thanks! What's the benefit of not having the factory flow? Are you aware of any other intakes that are similar to BMS?

Also, how's the induction sound with the burger unit? Thanks!
