Definitely go for the FMIC. It helps squeeze a little more boost and timing out any given octane fuel. If you're just going to run gasoline, you don't need to upgrade your lpfp.

I live in Utah and I cant seem to find a decent tuner so any one who knows someone in the Salt Lake City area I would be willing to pay to help get my tune set up.

My question is do I need to purchase the 3.5 BAR upgrade and the required OEM BMW sensor part number: 13627843531 to take full advantage of my turbos? I currently have the following mods.

2008 135i MT with 58k. White with M Sport Package.
Short Shifter
AFE Intake
3" VRSF DP
Axle Back Exhaust
JB4 G5 ISO with newest firmware
Vargas Stage 1 Turbos
BMS Cowl Delete
BMS Oil Cooler Mod
Charge Pipe with Tial BOV

I am planning on going with MHD for the BEF so I have everything set up I just havent pulled the trigger due to not knowing if I need the 3.5 BAR upgrade.

I have not upgraded my intercooler or the LPFP but I am torn on what should be the next upgrade. My goal is to run a solid 400-450 whp without having to run E85 or Race fuel. What do you guys recommend? I dont do track days or drag strip pulls I just drive spirited in the canyons sometimes. I drive my car hard but not for extended periods of time. I am leaning for the fuel pump but any advice is welcome.

I am new at the forum thing as well and I couldn't figure out how to start a new thred with these questions so I posted here.

Default MHD flashing process - 01-04-2017, 07:11 AM

Hi all long-time reader, but non-poster here. First off thanks to all the wealth of knowledge on these forums - I've read many useful posts and have become very familiar with my e90 n55.

So I have a general question about the MHD flashing process and to be honest am gun-shy to pull the trigger as I'm afraid of bricking my ECU. I have updated the JB4 to latest ISO verison (v13).

I have all the necessary hardware and purchased all the necessary software.

1. Set JB4 to "0"

2. Connect Battery charger at front of car - I have this charger (Schumacher SC-1200A-CA SpeedCharge 12Amp 6/12V) and *new* car battery - anyone use this before?

3. Execute flash via phone / KDCAN & OTG connection (used KDCAN before for Alpina flash, so should work fully for this, right?)

I am most nervous about power going out as my understanding the flash takes ~40 min. - just don't have confidence there. Can someone please share their experiences in flashing and/or confirm what I have will get the job done?

My car is an '11 e90 N55 with JB4 running for the last 2 years without any problems, no other major modifications. Just got the bug to mess around again :-)

Thanks in advance and happy New Year!

put phone on airplane mode also.

I have done this several times. it does take 30-40 minutes. Never had a issue as long as JB4 is set to 0.

Make sure to set to airplane mode. If you get a call during flash it can create bad times

Leave your door open, turn off lights and climate controls, and don't be tempted to fiddle with any controls while it's running. Start the write and go away for a half hour and then come back. You would be amazed how difficult it is not to screw with things if you sit there the whole time.

You will know right away if the cable is an issue because the app won't be able to connect to the ECU...and will tell you so.

Place the phone in airplane mode so your flash does not get disrupted. Pull the fuse to the fuel pump and your car will not drain the battery nearly as much. Do not flash with the door open but rather with the window down. This way You can start the flash and walk away. Make sure everything is off that doesn't need to be on. Climate control, headlights, heated seats, stereo, ect.

I have had the car die on me during the initial flash even with a 10 amp charger hooked up. If it fails you can flash it again. Being that you have a newer battery it shouldn't really be an issue but i'd rather play it on the safe side.

*sigh*...door open or door closed...the point is to leave it that way for the entirety of the flashing. Don't open it if it's closed and don't close it if it's open.

I have flashed many times with the door open while sitting in the garage with no ill effect...though I do have to turn off the interior light. Easy either way.

To be clear, Door open or window down is the same thing as long as you do either one correctly. If you do it with the door open, make sure you don't close the door when you leave. If you do it with window down, you need to roll the window down, get out of the car, close the door, cycle through ignition off, then back to on, then start the flash.

Hi Terry,
I have the same problem as fryj00 as below. Can you send me a ISO Firmware to test as well?

Here is a virtual dyno comparing JB4 w/MHD BEF and MHD E30 map that Justin sent over with a couple revisions.

JB4 was completely removed for MHD flash. Reinstalled JB4 (20min) and did that run 2nd.

Both same tank of fuel, same day, same temp, same road. About as apples to apples as you can get.

Sweet! Thanks for all the replies and advice, def. feeling more confident - I will pull #70 fuse (I think that is pump) just to be on safe side! Also I will make sure to do the open/close door dance for additional luck Will report back once it gets done to add my experience in hopes of helping someone else...

do you have boost and AFR from the flash only run? Or just post the JB4 and MHD logs.

Good comparison logs you posted.
What's up with your boost falling way below target, You on a stock turbo still? I see PS2 in your sig

Not sure, was told it's normal.

I have PS2 just taking forever to find time to put it on. I bought when it was a black friday deal.

Well, completed the back-end flash and all is good!

Took the car for a quick spin and it feels more linear, throttle more responsive. Butt dyno says more power, as accurate as that is...I did have a s*it-eating grin on my face, if anyone can relate. Burble is evident and adds to the overall *newer* experience of the car.

I'm very pleased with the initial reaction! Kudos to all! Will post some logs in the support section as soon as I get the chance.

Was nervous about the flashing process, but following all your helpful reassurances and guidelines it was a breeze - still, it was the most nerve wracking half hour (33:33 to be exact) I experienced... but honestly that was just my cold feet.

Looking forward to further developments and contributing to this site as time goes on!

Added v5.14 firmware to the N55 E ISO thread with a change to help back end flash performance during low to mid throttle when in mode 4/2. Could use some logs and feedback on it!

Yes please try out new firmware, night and day difference at least to me. Makes it feel more like flash only.

Does the BEF provide a more linear throttle mapping?

I don't see a pedal to torque table in Tunerpro like N54 has to change it how I like...

With the BEF first line of adjustment for pedal linearity is menu11 in dash.

Right, I wanted to map it to match PPK though since that's what I am used to and adjust from there. I just don't see a straight forward pedal to torque table. I see tps % to RPM.
