2008 535i - Dyno Day

008 535i Dyno Day
First of all, I want to thank Terry and SpecialtyZ in Chatsworth, Ca for there time and expert help.

And not that I forgot, but a BIG thanx and Love to My Wife, Rosie
I know the video is not the greatest, but I wanted to thank My Wife for the video, using her iPad 2, she's the GREATEST !!


Terry, well what is there to say that hasn't been said already, but for All those out there who are looking into tuning there BMW, N54 and N55, this is your guy, talk about support, he is there to answer your questions and today ( Feb 10, 2012 ) was no different if emailing or on this forum, he was supportive and patient and we had a great day, well at least my wife and I did. ( Terry can chime in if he wants and I hope he does )

Here my info

2008 535i E60 N54

Tune:

JB 4 - Alpha Firmware 2-7-2012
BMS DCI


Extra's:

Eisenmann Exhaust: Race


Fuel:

91 Octane - 40% ( California and there low octane, BOO !! )
E85 - 60% - just going by there quoted 105 octane, so don't hate on me

FYI - Been running 50/50 for the past six months with no issues

When I fueled up I had around 1-2 gallons left, when I added 9 gallons of E85 and 7 gallons of 91.



Here's the file

and

Here is one of the Video - Dyno Run Action !!














I

Isn't the N54 an amaaaazing engine??

All that power…all those gobs of torque...and moderate 20s gas mileage…

Totally Agree

Impressive, at least I was, I was actually surprised

Not bad at all, I guess that's why they call them, Sleepers

My buddy's E60 M5 posted 429 WHP and 335 torque on Dynojet recently.
You beat that torque by 100 lbs and not that far off on HP.
Scary for a little 3.0L engine.
Since the 535 weighs almost 300 lbs less than the M5, you should be very competitive in most conditions.
The M5 needs high speed and long stretches of high rpms to stay ahead of you. Anything but that and your weight and torque advantage will be a serious problem for an M5.
Nice going for a sleeper sedan.

Let's not get carried away here…the E60 M5 would destroy us.

Now, an E39 M5? Yes, it would be beaten.

Great thread!

I should of put on my title "400+ HP and Torque with my 2008 535i - JB4 and DCI ONLY !! "

Did you notice a significant difference when you upgraded to JB4?

HELL YEAH !!




When I take out the JB4 for major service, and no, nothing to do with the tune, it DOES not feel the same.

Power, torque, throttle response with JB4 =

I think he meant going from Jb3 to JB4. Maybe not.

Anyway, the very latest update is even smoother and has more low/mid range thrust. It's a Feb 2012 release, hope you have the cable for updates.

Since JB4 doesn't activate until oil temp reaches 160 degrees I was thinking of adding a remote start so it is fired up as soon as I get behind the wheel. The car feels sluggish and anemic without it. I usually start in Sport mode, then go to D when JB4 is firing. No need to have Sport after that unless you are racing.

[QUOTE=Oceans10;6632109]I think he meant going from Jb3 to JB4. Maybe not.

Only had JB4 when I started
Recently added the BMS DCI

And been testing E85/91 50/50 blend

So far so good

Loving the new alpha fw - 2-7-2012

Map 2 - lots of power and runs smooth

Personal Map 6 setting when I did my Dyno run - WOW !! -

With ONLY, JB4 + DCI E85/91 ( 60/40 ) - only for testing purposes


To be safe and for my personal opinion, I will be using 50/50 when available

Not that I am doubting you, but something seems a bit off here. A stock 2008 535i is 300 HP at the crank, not at the wheels so you have to figure in drivetrain loss. Most stock 535i's are around 250 - 260 HP on a dyno stock. If you are running 301hp on map 0, then either the dyno is off or you have more mods then just a DCI.

Maybe the E85 fuel??

You can doubt

But E85/91 to makes 98 octane which makes a difference, especially our our N54 twin turbos

And why would I not mention, if i had any more mods for more power, I get nothing out of it.

The guys at SpecialtyZ are professional and knowledgeable and current with there system, believe me they know their stuff.

They, SpecialtyZ, and that's including me and Terry, were actually amazed that with my tune and RACE fuel rating made great power, well at least for the 535i

That's all I can say, I wish I had more mods = more power

You can go to the N54tech website community and ask Terry for more info.

I'm not a pro, I just posted to share my curiosity on E85/91 octane mix and to have a FUN day.

Which I did

If the JB4 is on map 0 (and 0 is a true bypass), the engine itself wont advance timing with higher octane so there should really be no HP gain. I'm not trying to start a war or anything, it's just odd that i've never seen a stock 535i with that much HP at the wheels.

In comparison, I ran a 268hp with DP's, an aftermarket FMIC and upgraded DV's when my tune was bypassed.

I just ran an octane calculator... with 9 gallons of 105 and 7 gallons of 91, that equals 99 octane. You may have a factory freak car but running 6 more octane then a 93 should not equal 40 HP. I don't know if Terry/BMS is on this forum but i'm really curious if the JB4 is still tuning some parameters even when in map 0. Again, not doubting, just trying to keep it realistic as your results are not typical at all for this platform.

I'll agree that the map0 data doesn't look right but the ECU will notice a difference between 91 vs 93 octane. As to whether it will facter in ~99 octane is beyond me.
Even the power/torque crossover happens very low in the rev range. Stock dyno runs it will happen at ~5200rpm just like most cars. But this one happens at ~4500 rpm.
No doubts about the power on the higher maps though, map0 is just interesting.

I'm running the "old" Jb3 2.0. I don't see any real benefits for upgrading to Jb4. If there was a dyno graph with jb3 vs jb4 then I would consider it if there was a difference.

xclone is right - those numbers are way off. I thought it the second I saw them but figured the figures must have been translated to crank HP figures.

No way those figures are to the wheels. But nobody measures to the wheels anyways.

Sorry, I should have been more specific. I'm running the JB3 and was asking if anybody who upgraded to JB4 noticed a significant difference. I'm very happy with the JB3 tune and if JB4 is only slightly better it wouldn't be worth the upgrade...especially for a daily driver street car.

If someone has any dyno graphs showing the difference between JB3 and JB4 on the same car would be great.

I think skysurfer is running a cat back exhaust as well. Not that it would add a +40rwhp but it should help some.

Maybe it's just me but when I pull my JB3 out to have service the car still feels stronger that stock for awhile and after driving for a day it seems to return to stock. Maybe the ECU adjusts to the tune and keeps that for a short time. That could possibly explain switching to Map 0 and doing a dyno run would equate to higher than stock numbers. Just a theory.

Eisenmann Exhaust - Race

No matter what, still had a great time

If anyone has some time to kill... you tube "dyno fail" and you will have second thoughts about ever letting someone hook your car up on a dyno.

Aww…dynoing your car is one of life's finest pleasures...
