Hmmm ima have to look more into this. Some local guy here wants to charge 450 for stage 2 and e30 map just to flash and install.

that seems really pricey

if you already have an android device that particular setup would cost:
$40 OBDII cable
$3 OTG cable
$99 flasher module
$49 stage II map
$49 e30 map

$240 and 30-40 minutes of your time


if you want the monitoring module so you can see gauges on the device and log runs, it's an additional $69

if you don't have an android device, there are several cheap tablets available online for i think around $50

either way i would highly encourage you to do it yourself, the process is extremely simple and even if you start from scratch the cost would be less than $450

not really experienced with JB4 but i think it's $79 for both the flasher and backend map. i suggest asking on e90 or n54tech

no prob, hope you find a solution! im loving this car with a tune, both MHD and JB4 have proven to be excellent programs for the N54

Getting ready to flash my vehicle. Question, did you leave your door open while doing the flash? Thanks.

hopefully this helps anyone considering the app.

finally had a chance to install the MHD tuning flash today

installed stage 1 map. very happy with the results. car feels much stronger, especially in the higher rpm ranges. pulls much harder and is noticeably quicker.

total investment = $154.83 (returned the battery charger)

current specs:

• 2009 135i N54
• ~80,000 miles
• completely stock, not even a walnut blasting yet

installation tools:

• IPA K+CAN K+DCAN Cable from Amazon.com
• Micro USB OTG adapter
• MHD Flasher N54 App
• 8 amp battery charger

installation is very straight forward. made sure to use a battery charger as the entire process takes ~40 minutes and have read drops in voltages can cause errors.

no convenient electrical outlet at my apartment complex so had to run a long extension cable

battery charger


cables


OBD-II cable lights up


MHD app automatically opens


Back up stock ECU map


Purchased flasher module and stage 1 map (this includes stage 1 and stage 1+)


Selected Stage 1 map to do "full write" - switch phone to airplane mode


Flashing process - at first the car chimes and a few different symbols pop up on the dash but goes away


Flash write completed - process took 39 minutes

doesn't matter if you leave it open or not. last time i updated the map i left the window open but closed the door. note, your car will flash some lights and make a few sounds, thats nothing to worry about.

one thing to make sure not to do is push the key during the process (dumb i know, but without thinking i did that and it turns off the ECU and interrupts the flash). you'll have to start over from the beginning if you do that.

Can you send me a link where you got the cable i got one and it crapped out on me.

[Scooby2]

Ok. So that links banned.

Just google bimmer software cable. I just got one in the mail. Its one of the only ones guaranteed to work.

B!immersoftware cable

Take out the ! and replace with an I.

The Amazon and ebay cables are hit and miss so I wouldn't waste your time trying to source a cheaper alternative.

[Scooby2]

Are people running version 4 maps or 5?

I just tried v5 but it failed. Flashed stage 1 v4 and worked ok.

I must have bad luck! I got (2) k+d cables new and (2) otg usb adapter cables with an LG p769 android ver: 4.1.2 and still get no cable detection error (

i would double check if LG p769 supports OTG usb, from my quick google search i see results suggesting that it does not

[Willortiz]

Well damn really

[Willortiz]

Thanks again

The Google Nexus 7 supports OTG and is not too expensive. I got the base base model and it's been solid. I just keep it in my glovebox and pull it out when ready to flash. Works great!

great, thanks for sharing! the nexus is definitely a solid tablet.

would be wonderful if someone could develop a bluetooth solution capable of supporting the amount/rate of data transmitted with the MHD software. i know there are existing bluetooth OBD devices but don't believe they are compatible.

flashing and particuarly gauge monitoring via bluetooth would make for a nice clean cord-free cabin

gauge monitoring is fine via Bluetooth. Heaps of OBD2 monitors available out there on Google Play and Apple Appstore. I use Torque Pro - works well

Great write-up - Solid info. Much appreciated for those of us that like seeing pictures and details.

[Willortiz]

Whats good app for monitoring mhd one suck imo. $70 wasted
