Riding with map2 the last several days and I feel like the JB4+BEF stack is WAY more drivable than the standalone JB4 map2.

There's still a sudden dump of torque at around 4k RPM that will throw your head and butt into the seat, and can suddenly swing the backend sideways if not ready for it.
However, low RPM range is much smoother and is actually usable for daily use.

Boost levels don't taper to the pressure level of map5, but I'm assuming that's set by the map parameters.

Posted a couple of logs and will upload some more over the coming days and should get to an area with E85 next weekend. Looking forward to trying out various blends.

Would it be possible to have a log on any map, with and without the bef to see what has changed?
I installed the JB4 a few months after delivery of my M4 and drove it for almost 2 years before the MHD beta and adding the BMS BEF. In my opinion (and without objective data such as dyno numbers), you can't even compare the JB4 on its own. Adding the BEF makes the power delivery unbelievably smoother and the individualized tweaks that Terry provides for each driver/car set up is top notch.

Add in the MHD flash options (burble, VMAX delete, etc, and more to come...), and the entire system becomes an even greater pleasure to drive. I can't help but smile every time I'm on the road and enjoying a nice leisurely drive, then decide to put the foot down and get that rush of raw power.

Car feels super strong. To me, the logs look pretty good, trims dip for a bit in 4th gear, but honestly, besides doing logs, the car is not really in the rpm range for very long where it dips.
Just posting to see what you think.

A little negative side: last night a was abel to drive a little faster and make the pulls like 0-100 MPH - I got 2 times drivetrain errors No reduced power just error kicks in at 90 MPH when I'am in WOT without letting down the pedal...I made a quick MHD read out for DME codes, you can see them on the pic.
I made some pulls later, then no drivetrain error.

With JB4 Map 1 only (over a year since today, I never got this error when driving the car in the same way)
Today I'm able to make some logs with my JB4 and then post them here!
Here are the logs, 3th gear pull and 4th gear pull and the last 0-200km/h (125mp/h). ONLY one time I was abel to get the same drive train error, unfortunately I was not logging at this time. I straight cleared the codes with ISTA and then made several over 0-110MPH and 40-110MPH pulls and somehow no drive train error JB4 is up to date to latest FW (for BEF) and all settings are default. Need I change anything in options?

You need to update to PWG ISO firmware to use a BEF, and may need slow speed CANbus.

Can anyone give me some insight on the BEF instructions? do i just follow the original first page directions? I'm wondering which BEF map is best for my car. does the MHD app walk you through everything I'm just not finding good instructions for doing this BEF. also after all said and done which MAP do you run the JB4 on?

Directions are in the first post. The fuel used depends on the intended fuel usage. Always E85 mix, always pump, switching between the two, WMI or not, etc.

I'm always93 octane pump until i do WMI or E85. for 93 octane would i use the Race or Pump BEF?

I'm just confused so i download the MHD app unplug my JB4 OBD plug and hookup my MDH Flasher and flash stage0 for whatever the MHD cost. after this do i go back to jb4 to select a tune or leave it on whatever map because it seems as though the directions say to go back to jb4 and set the Future Use D to Bit 6. then go back to the MHD and download then load the appropriate BEF.

this is my first time doing this so sorry for being a noob

Hey guys,
just tested the actual BEF E85 map for the S55.

Anyone else having "problems" with the burble option? The burble only works the first few minutes after starting the engine. When I push the car the burbles won't get back until stopping and starting the engine again. Also having this problem with the normal RACING BEF map for the S55. It seems to be not dependent on the burble intensity or duration.

Bye

Hi, I posted my problem there.

Could you Terry please tell me here:

Is there no chance to use regular (no ISO) JB4 with BEF? Somehow my car operated well with it! Never felt so smooth and strong power.

After one year usage of regular JB4 I never need slow canbus, do I need now change the settings for canbus?

I successfully flashed stage 0 but could not flash the jb4 backend flashes to the vehicle. It states FILE NOT COMPATIBLE with this car 00002a471daa03 vs 000021571d8202
Does that mean I need a custom backend file for my car??

so after everything is flashed does the JB4 function as normal with options for multiple maps based on PSI gains or is there a certain map that we should use to utilize the BEF?

MHD is working / testing on that burble issue, they released a beta version yesterday: 0.993b.

Default Keeps getting better PWG1 - 04-18-2018, 04:47 AM

Had a few problems at first but is was due to not running updated ISO firmware. I am definitely seeing the need for my next mod, a F M I C, more boost equals more heat. I have posted a few logs for review.

Caution, potential bug in MHD 0.993b, see below.

4/18/18: I just loaded MHD 0.993b stock map0 that came out today (update with N20 TMAP flash option) and now getting permanent drivetrain malfunction (reduced power) mode code that won't clear. Steps used below:

1. Flashed MHD BEF 0.993b stock map0 (burble, limiter removed, and N20 TMAP checked)
2. Reflashed JB4 BEF PWG2 Race4c
3. Reconnected JB4 (running ISO10_T13 firmware) and turned on the car
4. Immediately got drivetrain malfunction, attempted to clear via JB4 but immediately came back up. Shut car engine off.
5. Suspected N20 option needed disabled in JB4 so disabled N20 in JB4 settings.
6. Restarted car, drivetrain error gone.
7. Drive 5 minutes, as soon as I got into boost drivetrain error returned, unable to clear same as before.

At this point I repeat the same steps, but this time when I flash 0.993b stock map0 in MHD I uncheck the N20 TMAP option.

1. Reflash MHD 0.993b, uncheck N20 TMAP
2. Reflash PWG2 Race4c BEF
3. Reconnect JB4, check N20 TMAP option
4. Restart car, drivetrain malfunction persists.


So FYI seems there is a potential bug with the new 0.993b firmware, at least with my car. I have 2013 F30 335i PWG.

There should be no TMAP sensor options in "load a back end" flashing option....

You are correct, however the checkbox is available as a flash option for stock flash in 0.993b. I flashed this with N20 TMAP checked, then flashed BEF PWG2 Race4c and the checkbox shows grayed out in the BEF options, but while grayed out it shows option still checked from when I flashed the stock MHD flash in 0.993b. I hope that makes sense.

Got off work today and car started and issue gone. I still think the double N20 enabled option both in MHD and JB4 caused the error and undoing it in MHD reversed the issue I had but maybe I just needed to wait for DME to fully power down or something? I don't know guys but anyway things working again for now.

Just out of pure curiosity, how does MHD’s OTS stage 1,2 & 2+/E85 maps compare to BMS BEF pump, race & E85 maps in hp/tq numbers on FBO F series.

Tried flashing BEF today using the new MHD v. 99c and got a "Coding could not be read..." message. Have been flashing BEF since the beginning, and every MHD update with no issues... Anybody else had encountered this?
