Blackhat, no MHD flasher before v1.7 will work on your DME without a bench flash.

Looks like you are on the correct path now with v1.7. Clear codes, clear adaptations , and switch to map 0 before flashing. After flash Set menu 4 to item 2: BEF on. Then make sure you are still not on map 0.

That’s basically how I did it.

I dropped menu 11 and 12 to 20 and now I’ll adjust from there. My initial settings were higher from before BEF and were causing very high boost at low throttle.

Oh my oh my oh my! The difference with the just the pump BEF is giggling impressive. I didn't know how much was left on the table without a tune. I just figured the DME would learn and the PI would compensate. MHD v1.7 was/is worth every penny. I can't wait to start turning it up

@drwillb
I found turning menu 11 up to 2.8k was a sweet spot for my neighborhoods. I'll find out tomorrow on I405 how it does there. I'll be sure to log some simple 3rd pulls. I'm curious how my trims and timing are effected. Thanks again.

I have a question about menu settings 10-11-12. I was looking at the setting though the app and I noticed that menu 10 was set at a value of 10. I know it was 60 stock from what I have read. So i adjusted it back up to 60 to see what it would do. What i noticed is that it would start to build boost under light throttle even when setting cruse control to 35 MPH. When I set it back to 10 is takes a little more throttle to make boost. I have played around with menu 11 and 12 but the only thing that seems to make a big difference it menu 10.

About setup, I bought this car used with the JB4 already installed. I have since added MHD BEF running the PUMP map. The car had a new factory turbo installed just before I bought it. It is also FBO running 93 on map 5. Boost dose not seem to have trouble hitting target under hard throttle.

Current Settings
10 = 500
11 = 1000
12 = 2500

@67stang,
In the E Chassis N55 JB4 thread: E Chassis N55 JB4 - N54Tech.com - International Turbo Racing Discussion, it says under faq: menu10 set to 3000rpm, menu11 set to 1000rpm, and menu12 set to 2400rpm.
Sorry, what was your question?

I got that, but when I set it like you show it dose not seem right. Mainly with changing menu 10 too 3000 the car starts to build boost almost immediately with even sight throttle. with it set at 500 it seems to come on with closer to 30% throttle. I was just wondering if this was something I should be concerned with.

67stang, menu item 10 is for default wastegate position so it does affect your spool when off the gas completely. It is also used to take slack out of the WG rod in order to mask rattle. I've always kept mine at 3000.

Item 12 is for WG when you are applying throttle coming off idle. The low end of the suggested settings is 2400. I would keep that there, too. Mine I've run as low as 2000 but I have a PS1 so I figured my boost numbers are higher than stock at any given WG setting.

Item 11 is where you really want to make your adjustments. This is basically how quickly the throttle responds to your pedal inputs and doesn't affect WG. If this is too high for your car then you will go into overboost easily and get dips in boost/throttle/power that you will feel. Setting this to "0" is stock throttle response.

Right now, my settings are:

10 = 30 (= 60 DWP)
11 = 24
12 = 24

I started at 30, 20, 20 and I'm trying to dial it in.

Of course, I may have this all wrong

Thats whats odd to me. I think I have an understanding of how it is suposed to work, but when I set all three as you have yours it dose not work. I was building 6psi with 10% throttle input as soon as I took menu 10 down to 12 (aprx 700rpm) it is fine. I don't seem to have any issues with it there just trying to understand why it need to be set so low. It dose have a new turbo on it as well from the dealer.

One other thing I thought was strange is when I set menu 12 to 2400 after going out and coming back in it was set to 1200. I tried this twice and both times it changed.

@67stang, I've played with 10 and 12 before. Trying up and down the gauge to see what felt best. I know if you set 10 so low, the potential max value of 12 decreases. Why? I think it's to prevent massive bucking/jerking when you transition from idle WGDC(10) to throttled WGDC(12). Could be way off per usual.

Stang, on the 1 and 3 series forums there are several people with the sudden boost at low throttle problem. This seems to have surfaced when v1.7 flasher was released. I just looked an MHD responded to a post there. Let's see if there's a glitch somewhere.

For people with just MHD only, it's a big problem. For me (us), having JB4 allowed me to dial back setting 11 to get the boost response more linear. I just did the DME unlock and BEF a week ago and the first thing I noticed was this boost jump.

I initially dialed back to 30, 10, 20 then worked up from there.

You wrote that you bought the car with JB4 installed. Are all your settings at stock? Do you have any duty bias dialed in? Do you have menu 4 = 2 for BEF? Did you reset adaptations, menu 1 = 4?

Capture a log if you want us to check the WGDC relative to boost and guess if the turbo is misadjusted.

I threw a code 36BE then went into limp mode this morning under hard acceleration but not WOT, map 1, just under 25 psi before coding.

I searched and found that it's got to do with the DME and shows up after flashing. I didn't find any solutions but it seems to be a benign thing. Fingers crossed

I think 36BE is BEF/MHD thing. I just started getting it too, ever since flashing. It's the MHD flash process, the JB4 BEF file or the combination of them. It'd be interesting to try JUST a flash or an MHD purchased BEF and see if the 36BE goes away. I'm getting tired of clearing it every morning

Well, 36BE happened again this morning, along with some other codes. 2nd gear moderate throttle but not WOT. Boost jumped to 22psi and then the car coded and went limp.

This is definitely a new thing since BEF.

I too was getting the 36BE code all the time after recently flashing my X1 with MHD's new no-DME-unlock-needed version 1.7 (I am running the PUMP_BEF with it). I would clear it with the JB4, but it would be back every time I re-started the car. Did not get any limp modes however.

I did some googling and found the solution: clear the 36BE with MHD. After doing that, it has not come back . Apparently, there is a difference in how MHD clears (some?) codes compared to how the JB4 does it.

Thank you for the tip. I'll try to cause the code to come up this weekend and use your fix.

If it's as simple as that(use a different app), I owe you a beer. I wonder if it'd also work on 2EF2. I came along after the Flasher too. I wouldn't mind clearing that for good too I'll try it before heading to work this morning. I'll know before I get there. Stand by...

Got to work and no CEL. I forgot how much I've trained my driving habits to avoid CEL's. I haven't driven normal(cruising in D) for ages. We'll see what happens on the way home. That'll be the true test; in heavy traffic, darting around.

Quick question. I have a 2013 X1 35iX and I'm running a JB4 with the MHD BEF 9E60B_PUMP file and just wanted to make sure that's correct. I just run pump 93 on a stock fuel system. Car seems to run fine, just wanted to make sure that's correct.

e36addict: yes, 9E60B_PUMP is the correct file for the N55 X1.

drwillb and blackhat75: here's hoping that clearing the 36BE with MHD will work as well for you as it has for me. Fingers crossed.

In a sort of related vein, the 3166 code ("Tank safety valve: malfunction") and it's associated nuisance CEL was basically a fact of life for me for the three plus years I've been using a JB4. I must have cleared it hundreds of times. Now that I've been using the PUMP_BEF, it hasn't recurred once .

Thanks @MrHaloHalo . I think it'd be neat if there was a way to reclassify(to shadow codes) certain codes when they come up that aren't engine critical. I think BMW's have the most elaborate code definitions of any manufacturer. If I were to go to the dealer every time CEL came on, well ...I couldn't afford a DD BMW.

Right on!

I think the JB4 kind of had what you're describing way back when it had the "auto clear" option - non-critical codes would not trip the CEL. That was scrapped when BMS had to become completely CARB compliant.

I've found buying a BMW new, modding it, and owning it long past the factory warranty period is not for the faint of heart. But plenty of DIY, perseverance, and using the resources available on this board (and others) has kept my costs pretty reasonable.

Edit(PM 7:10) Returned home, still no CEL. Even more traffic than usual due to leaving late. [Note: Generally, people are terrible drivers, especially in the rain.]
I'll keep watching for CEL, mostly out of habit. I think the MHD clear codes method is successful. If this proves continuously effective, I'd like/hope to see a collaboration between JB4 and MHD programmers to remedy this bug. It's not life threatening but certainly not what anyone wants to deal with, especially after the investment.

Default Map 3 with backend flash - 12-21-2019, 08:32 AM

Is there a list of the differences running map 3 with the mhd bef? So far I have been on map 2 with the pump flash running an E40mix. I have a BMS meth kit installed for the hot Florida weather. Will map3 run higher boost targets with mhd bef like map 1 and 2? I was also wondering what changed with the e85 bef compared to the pump file? I have looked around but have had no luck finding all the info I was looking for on this?

I believe the biggest difference between the BEF versions is the timing table. For pump gas, you'd want a more conservative total timing whereas with the E85 BEF, you could handle a more aggressive timing schedule map. If there was a raceBEF, I'm sure I'd be similar to it. I'm sure there's much more to it but that's what I think.
