MHD finally has OBD DME unlock for late e-series cars.

I ordered the WiFi adapter from Burger and now I'm awaiting its arrival so that I can finally do the Burger BEF.

Should I do the 98G0B pump flash since this is still an unlocked DME?

Hi Drwill!

Super exciting news, eh? I flashed MHD/Twisted's stage 1+ yesterday but am going to try and run the BEF as that didn't feel right. I'm going with the 98G0B_PUMP_USA I guess. I'll let you know if it blows up.

98g0b is for the early e series that come unlocked from the factory. You use a different rom.

Haha, just found that out when it told me wrong ROM. Flashed 9e60 pump and first impressions are amazing. Very smooth.

Pardon me for asking but @boostedn55135, are you saying you've flashed your DME with out having to remove it and send it in for physical rework? I have a 2012 N55 with a MEVD1726 DME which(till now I hope) needs to be removed from the car and sent out for benchflashing. Did they figure this out now? I'd love to finally BEF the JB4.

Correct - there is no longer a need to remove and bench flash the dme, MHD did it! I purchased https://burgertuning.com/products/mh...-flash-adapter , downloaded MHD, bought the license and boom, flashed the unflashable!

Blackhat, this update to flashing is only 1 week old so don't feel like you were left out.

I bought a Kindle Fire 7 for $29 this weekend, loaded all the necessary software, and ordered my wifi adapter from Burger. I'll be flashing before the weekend is here!!

So excited they finally did it. I loaded the E85 THR to go with my XHP transmission flash. So. Much. Smoother. Also loving startup roar, cold start delete, medium burbles (will probably turn down the aggressiveness at some point, but it's hilariously loud right now).

I pushed this update so far back in my mod list, I forgot what I was going to do,lol. I think I was just going to do the JB4/BEF Pump but over the last few months, MHD flashes have made leaps n bounds. Maybe I'll try a JB4/MHD hybrid. I love my JB4 and wheel controls but I kind of want some of the MHD widgets too. So many choices!

For me, the main reason for MHD interest is the timing control/adjustment for the larger turbo. I'm not sure it there'll be a way to adjust that or just load a 'known good' timing/fuel map and test it out. I heard something about antilag? Burble something too? Maybe try those out. I should just be thankful late E-series have BEF capability now.

With MHD you can do a custom tune once unlocked. The BEF + JB4 will make JB4 much better but a custom tune will really dial it in.

I run a PS1 and dialing that in on map 6 has been a lot of trial and error and re-adjust. I'll do BEF first but I see myself with a custom tune this spring.

Timing is one of the components that changes between BEFs (Pump, E85). You can also customize these if you know what you're doing. Not sure about antilag on N55, but burble and other flash-time options apply to BEFs. Just select... at flash time.

Until now, I've driven around with the PS2 at 16psi and port injection(+BMS controller) to help with knock. It works great but I feel trying to go any higher without a timing correction is risky. With no E85 within 100mi, I'm stuck in the 90's with good ol' 92/93oct. As much as I'd like a professional tuner software to tune my own maps and controls, I have to think that Terry, BM3, Wedge and the like have more experience than anyone and any flash tune they'd put out will be 'as good' if not better than anything I'd create. I just want my JB4 and a flash for the PS2 on 92/3 +PI meth

Hi first time posting here...I have a 2013 E88 DCT going off CPO warranty next month and have recently looked into tuning with JB4/FBO, and the MHD BEF seemed like a good idea for DCT since (based on my research) it appears to eliminate slip issues following a JB4 install.
I confirmed that my engine has the MEVD1726, so doing the BEF was going to be a hassle since (up until now) I thought it required removal and sending in to unlock. However (after reading the news above) I just checked MHD's website and it still states this in the FAQ under Support/What is a Bench Flash:
"MEVD1726 eqipped BMWs need a one time bench flash in order to jail brake the ECU to allow flashing via the OBD port. This process requires uninstalling the DME from the car and sending it in to a MHD partner for the jail break / unlock."

I'm hoping they just haven't gotten around to updating their website, as this development would be great news for MEVD1726-equipped N55s.

Correct. I flashed my MEVD1726 equipped car on Sunday.

I checked MHD FaceBook page right after I posted...they have the news regarding the new update there: "*MHD N55 E-series Update 1.7* - Direct OBD flash on Late E-Series - no unlock needed anymore"

Is there currently no BEF for upgraded turbo(PS2, VVT, Speedtech, etc)? It looks like the deciding factor is your fuel of choice.

We usually have larger turbo setups start with the same BEF and evaluate.

I F*CK UP!!
I think I bricked the DME! I was successful at loading the $199 flasher yesterday. Just now, I went to flash the BEF PUMP(twice) and I'm getting "Failed to write the ECU. DME Status: Engine program signature verification failed". I turned off lights, seat belt on, fans off, ign on. I forgot to set JB4 to MAP 0. I've tried to bluetooth into JB4 to set MAP 0 but fails. I've tried wired in to JB4 and fails. How screwed am I?

Before it starts writing, it looks like it erases everything without checking if it can write back first. ...Both times it got to 100% writing files before giving me the failed mission.
The car currently just turns over infinitely; dead.

The cable/OTG combo I'm using has worked loading xHP so I'm thinking it's not that. It also completed the erase/write process so I doubt it's the cable. I'm scouring the net and see several guys have bad battery chargers or low battery to blame. I live in apartments and don't have a 200ft cable to run a charger out to my garage so I just used a a jump box. I'm thinking of bugging my neighbor to see if he'd mind jumping me for 10min just to keep the voltage up the whole time. Do you guys think this would help or hurt?

What an intense few hours it's been. I've managed to get the car running again. Back to stock and I'm perfectly happy with that. I think I've narrowed it down to a corrupt flash file.
The only file that seems to load is what MHD came with referencing 'STOCK'. Once flased back to stock, any file(I have downloaded) seems to reach 90% completion, then says the same message, "Failed to write the ECU. DME Status: Engine program signature verification failed". I think I must have downloaded and tried to move files from my phone to a new SDXC card with similar, earlier version files, existing on the card already, adding a weird extension to the files. That or data corruption somewhere in the transfer. I'll try to wipe the sdCard and only have one version of only the lateset recommended BMS BEF files. My neighbor lent me his keys to an Explorer so I can run it to keep my charge up(+12.5v) while figuring this out.

Notes to self:
-Set JB4 to MAP 0(zero)
-Disable xHP/xDelete or any other app which has a connection to your car automatically
-Airplane mode so your incoming girlfriends pics don't corrupt the CPU's flash process
-Ensure NO other apps are running on the phone/tablet
-Battery is connected to a battery charger(not a quick use jumper pack)
-All aux functions are turned off(lights, fogs, vents, A/C, dash lights, etc.)
-Have a 'Plan B' for when sh#t goes south and things don't go like the forums say

I did the DME unlock for late e series yesterday using the 1.7 flasher and I loaded the BMS BEF.

I noticed a low throttle big spike. I was consistently getting 18.2 psi at 2500 rpm and it was coming on fast.

Since I had read a thread about this prior to flashing I was on the lookout for the situation and had thought about solutions. I didn’t see a linear throttle option when loading the BEF. However, menu item 11 in the JB4 steering wheel controls is all about throttle sensitivity. This was at my previous setting of 25 so I lowered to 10 and the problem was gone. I then started raising the value and got back up 20 with no boost spikes.

I’ll keep adjusting and logging today to see how high I can go with it and also look into DB tuning to address a low FF curve in the top third of the plots.

Which BMS BEF file did you use along with the late E-series flasher?

Question: Since reflashing back to the MHD 'STOCK', a message came us saying 'if you've applied the flasher, it'll be removed, are you sure?", or something to that effect. Do I need to redue the late E-series flasher again before attempting to flash 9E60B_PUMP.bin file?

Also, if I don't need the 98G0B/98GOB.bin files, can I delete them from the downloaded .zip folder to save space and streamline the MHD file selection process?

After some fun digging around, I've found the manufacturing date of my car(VIN:WBAKF9C53CE859607) is 2012-05-02. I have the MEVD 1726 DME though. Should I be using the 98G0B.bin files or the 9E60B.bin files? Nevermind, MHD's HW: 9E60B confirmed

I apologize for the repetitive editing and elementary questioning. I've come to respect this whole process more than I had when I started.

Google finally got around to reminding me to update my MHD(along with 16 other apps) to v1.7, which has the late E-series flasher updated needed. I think this might be what the problem's been the whole time. Going out to try now.

Final update:
After updating MHD and everything else I should have checked off doing prior to flashing, the car is back up and running. I've switch JB4 from MAP0 to MAP1 and switch menu 4/3 to 4/2 to indicate I'm using a BEF. It was strange that my AFR/AFR2 were'nt reading correctly at first. It was stuck at 4.3, on and off the throttle. Once I changed the MAP, it started working correctly again so that was good. I began driving the car around the apartments and something felt off. The transmission was starting in D3! That's not good. I tried manual mode, up and down and the shifts worked but it felt wrong. I brought the car back to it's stall and nervously grabbed the DCAN/OTG cable. I think with all the flashing/erasing/modding/swearing!, something must have gotten corrupt. I brought up xHP app and quickly reflashed it. Only took ~2min. It flashed successful! I backed out again and tried to drive around the block again. Everything's back to normal(siiiiggghhh). What an adventure. So now I have the JB4(which I love), using MAP1(for now),running the 9E60B_PUMP.bin BEF under menu 4/3, the direct port injection meth still operational as before and xHP stage 3 functioning correctly. For now, I'm leaving everything alone and just enjoying a running car. I hope noone else has to jump threw the learning hoops like I did but if so, I hope some of this information may be useful.
