Load won't lie. I was running v1.2 MM stage2+, it's detuned from v1.1, less boost
so probably 410-420whp. Since whp moves with rpm range, we don't know where is the peak power. I was assuming 5500-6000rpm. It won't be accurate.

Do you have the dyno and log of this run?

Small update: slightly reducing boost seemed to fix the misfires.

Going to do more logging next week to see if more revisions are needed.

I tried, and they said they would not make a more aggressive map over the stg 2+ e30. I had even mentioned that they were previously working on an E50 map. I wanted to see if I can go deeper into the 10's in the 1/4 mile to help people so that a new updated and more aggressive map could be made in the future

Custom tune.

Ah you have an F30 right? I think they’re only developing this map for the M2 right now.

Let us know how she does!

I’m looking at dyno’ing the current Stg 2+ MM to see how it differs from the previous, my Stg 3 MM that’s a slight boost increase of the current Stg 2+ MM, and my Stg 3 MM v2 that’s my hot map to see if power drops up top or not.

We can set up an NGP dyno day when you’re ready!

As a tuner who's tuned more cars than I can count on both hands and feet, and n55s, let me tell you that your misfires are related to your coils being weak overtime + a combination of thr turbo running out of juice.

19psi is about the highest you can run at 6300~+ before the car starts to buckle and contribute to misfires. Assuming stock turbos, I could not quite tell if you are stock turbo or not.

If you have any questions I'd be happy to assist.

No, I don't.
For stage3 MM, Halim refused to crank my boost up which I understand cuz I didn't pay him. All I got is 22psi flat boost to redline. Low 80s wastegate%.

He did a second revision based on my log for S63 M5 EU5 injectors which proves that BM3 drop-down menu is just to get the car run. It threw rich mixture code after 10 miles of driving. 2nd revision fixed it.

I switched back to my custom tune later.

I'll wrap my custom tune up very soon, will dyno it both original MM v1.2 OTS and custom E50 tune.

I’m running the Pure500.

Thanks for the insight. It’s reassuring to hear this is a common phenomenon. If the stock turbo’s limit is 19psi, then the Pure500’s is around 22psi, based on my misfire experience (and looking at my WGDC).

Nice! That'll be the next upgrade for my personal m2. 22psi sounds about right given the unclipped turbine style of the pure500.

If you were looking for a custom tune, feel free to reach out and I can help to see what the limit is

[ThreeStripes]

Isn’t the limit of the stock MAF 21.xpsi? Did you upgrade to the 3.5bar sensor or is the stock unit getting it done?

Might not have been necessary but I upgraded. But on the stock turbo the stock TMAP worked with Stage 2+

Thanks for understanding what I meant. Ordering one now.

Yes, I don’t understand why they wouldn’t want to. I ended getting a LT4 hpfp and installed that along with an ethanol sensor to utilize the flex fuel capabilities. So far, I don’t like the E50 increase since it is so minimal, and at E70-E79 I’ve seen the biggest increase in timing but the current fuel system isn’t liking it. I need a few more logs with the hpfp angle to determine if it is the lpfp or the hpfp that isn’t keeping up.

Tbh it is rather disappointing, as my 340i will handle E80 without an issue with the exact same setup. — stock lpfp, lt4 hpfp, stock injectors, stock turbo, stage 2+ multimap w/flex fuel sensor.

It’s all in the tune, 100% sure. I know of a few people who have the same exact setup on their F3x N55 and they can run full e85, (so that’s usually e70+ from the pump for them) and their maps are slightly more aggressive than this e70+ ots ff enabled map without an issue.

I’m not spending money for a custom tune on the stock turbo. Extremely pointless to me. If I had an upgraded turbo, sure no problem.

Same tune? Or custom? How much of a difference is there between your cars?
This is just the limit for you because BM3 isn’t going to develop a 1 off tune for free.

Edit:
I think I also remember you being at or near 100% duty cycle - there isn’t much growth there. You still have the stock inlet and intake, right?

I’m not understanding your first two questions. I’ll try and answer it though, both cars 435i and 340i are on BM3 OTS stage 2+ Multimap w/flex fuel enabled maps utilizing a flex fuel sensor. Difference performance wise, parts wise, power wise?

Nobody is asking for a 1 off tune for free. I’m asking for the same tune that they have already made and have other people testing it out.

Stock air box with upgraded inlet. WGDC fluctuates roughly 90-95 throughout most of the run.

I’m asking two things:

What are other people (F30 N55) seeing hat you’re not?
Are they on the same tune or custom tune?

I pointed out your WGDC because the M2 supposedly has a freer flowing exhaust manifold, exhaust and of course intake. Your car was already tapped out, pushing almost 100% duty cycle. If you didn’t have that exhaust - there wouldn’t be any way to go more aggressive.

I think we talked about it before, but you really need to cut that stock intake box and create an additional opening - it’s really hurting the potential.

I checked a log of mine and on one pull I’m at 17.5psi at 6200rpm and 84.9% wgdc. M235i - RK intake, MST V2 inlet, VRSF Race intercooler, ***less DP, AWE midpipe, Performance muffler.

From what you’re saying, there is a 10% difference between us. No way most people are going to do all that just to run a slightly more aggressive map.

Looks like it’s about time to hit the dyno. Here’s a log of my v5, which is likely the last for now:

https://bootmod3.net/log?id=661aa1904e98584cb49eb2b8

Looks pretty similar to your v2 logs from what I can tell.
