I went to a dyno today and did 3 dyno pulls. 2 pulls on map 7 and one pull on map 2. car made 504whp and 504wtq on map 7 and 451whp and 461wtq on map 2. The 328whp run is a friends 100% stock 2018 440i on the same dyno.

please look at my logs and tell me what need to be done. The car is running the mhd back end flash e85 flash for hybrid turbos. The car runs 50%91 octane and 50%e85 which comes on to about 44%-47% ethanol. Car has full bolt ons with the pure stage 2 DD turbos with RB inlets. stage 2 low pressure pump and i do not have port injection. Car is also running spec stage 2+clutch and oem dual mass flywheel.

Also i tuned my turbo s2000 there on the same day. s2000 runs on e85 with a garrett gtx3076r running on an aem ems, with pretty much everything done to it.

here is another log

Strong #s - very impressed. Clean rides, too


Have you butt dynoed with weaker e85 blends? I mean, do you feel the big power picked up only after you closed in on 50% ethanol? That 91 crap is so hard to work with Im curious to your experience on e10-e30

I know a guy from Long Beach that got his E93 dyno'd and looks to be the same shop.
You from SoCal ?

Overboosting a bit in the midrange.
Hpfp dips a little but I believe that is caused from overboost and throttle closure. lpfp dipping as well. I would upgrade lpfp and run PI if you want to push more. If happy as is, I would do a little duty bias tuning in the midrange.

thanks for this info

i Dont understand why i need to upgrade the single walbro 450 fuel pump because I make well over 600whp on full e85 with a single walbro 450 in my honda s2000. I'm only making 504whp with my 335i amd it only runs 50%e85.

but yeah i been thinking about getting port injection.

Do you think there is more power to be made with my 335i without upgrading my single walbro 450 and with out getting port injection.

Did they tune or dyno only ?

They are a tuning dyno shop. I have been going there for 15+ years for all my hondas and evo. But they do not tune the n54. I cannot find a dyno that will tune my 2007 335i. None of the biggest import dynos shops will tune my 335i. Even the bmw dyno shops will not tune a n54. . I called ssr performance and european auto source and these are big bmw tuning shops with in house dynos and they said they do not tune n54 cars!!!

Righttttt, I remember you posting about that now.
From the log I looked at, it needs very little to be fully dialed in. Overall log looks ok, but I would start with the overboost.
Higher the boost, as you know, the more fuel required. So I would start from there and see if hpfp and lpfp are a little happier .
Not a huge deal, but I would start from there and evaluate if it were my car.

Different turbo(s), motor, compression ratio, etc
As far as more power, you can probably squeeze a little more out but not much. Not safely anyway.

Looks nice.

Two points I'm curious about, if I may...

What's with Trims 2 being 0 the whole time?
Is that a matter of being aftermarket turbos? Or?

Also, yes, your timing is tight, even perfect. I'm envious.
Just curious about the overall engine health - mileage, intake port cleaning, etc.
My timing is decent, but not flawless. It happens to be more advanced and maybe if I pulled it back it would be flawless as well. Just curious.

Agreed your FP_L is getting into the hurt zone. Just keep an eye is all.

[BIMMIN]

I'd get a better tuner man.

Also ditch the jb4 and get a competent bmw tuner for a legit tune controlled by your dme

I am just curious . What is wrong with the jb4?

Nothing, just takes some time and know how to dial it all in. If you're a DIY kinda guy then jb4 is awesome!

[BIMMIN]

Nothing really wrong. But in my experience before I went dme flash tune. I had way too many issues and bugs. Would get 30ff code for no reason. Get random fuel pump over voltage codes, etc.

There are plenty of people who have jb4 trouble free and its everything they need. I made the decision to remove it and get a dyno tune from a expert bmw tuner and love it. No issues ever since, except my ethanol content sensor has recently started going nuts...

[Bmw335turbo]

Hit up David Shoup on Facebook......best n54 tuner around.

Given the fuel he is using and hardware (turbos, lpfp, no PI , Etc), what could a competent tuner do for him ????
The jb4 is not an issue,nor the tune, his hardware is what is limiting his power. Not everyone wants to push to the limits.

Trims 2 probably due to the firmware he is running or he enabled trims 2 to read under avg ign but id have to go back and look at his log to be able to tell.

I had looked at attached log only initially and commented on overboost, but in this log some settings are off that on the dyno run are more correct and does not overboost.

[BIMMIN]

What's up with the heavy dip in power during the run? Why is his torque curve dropping off so fast?

[BIMMIN]

Here is my hp and tq curve. My turbos and his are comparable. My torque holds pretty steady across the board. No heavy dips or anything.

No disrespect to bms and jb4. I'm just giving advice. I went flash tune with a professional tuner for a worry free car that runs amazing.

I had jb4 for the longest and had nothing but issues and ghost bugs and engine codes.

Why bang your head trying to dial it all in and still not be perfect. Just let a professional do it.

My tuner even wanted to dial it in with the jb4 first. He ultimately took it off
