Adding JB4 v13 firmware to the first post to collect some data.

JB4 v13 firmware:

1) Added active safety system for high fuel pressure. JB4 will revert to safety is fuel pressure drops below 7 (1000psi) during full throttle.
2) Moved safety/VALET map to map8
3) Adjusted map4 to be a performance map between map3 and map5. With the BEF map4 targets around 20psi
4) Adjusted FF learning to be slightly more aggressive.

Thanks Terry!

Any plans of doing a 93 octane dyno run, I Dont have E85 and Dont want to run meth.

Yes of course.. We're just focused on the higher end of the power band first since we know that is what most of our customers are waiting for.

Perfect Andy has been helping dial in map 7 with my bm3 flash, I noticed FF was always learning down compared to older firmware like version 8, hopefully I can break in to the 6.xx 100-200 with this new firmware

When running MHD flash with JB4 do I have to have the extra wires for the JB4 I think its the FF and ewg. Also my JB4 gauges are weird my oil goes up when I press the gas , from 0- 3000 degrees my throttle goes up to 300, those don't seem right.

Fuel pressure not required, EWG suggested but not required.

On gauges may need to lock doors and let ECU reset if updating from a previous version.

Default Help! MHD+JB4 Map7 Logs 👉 **** Show? - 05-08-2019, 07:18 AM

Hey Gang!

I hope to get some guidance on my Post-MHD/JB4BEF Settings I just MHD flashed my b58 with a JB4 BEF (ver.58/13/5 -- Map 7) and also flashed the TCU with x-hp (Stage 3).

I must be having substantial issues with my WMI and User-adjustable settings because I am experiencing the following:
  • Both transient & WOT are jerky—feels like throttle closures and I can hear the BOV opening when it happens.
  • Meth initiation is not consistent—sometimes it comes in on the gear (typically 2nd) that I start logging, sometimes it doesn’t.
  • Fuel Trims are too high...not sure how much the instability of the meth initiation is causing this.
  • I can't maintain target boost
  • AFRs have dropped enough to trigger a 118002 error "Mixture too rich" a few times.
  • Overall, the car feels just as, of not less powerful as it did before the MHD , and it's way jerkier.

FYI:
  • I live in Denver (5,500’ altitude)
  • These issues were not nearly as noticeable before switching to the MHD flash.
  • I have posted 3 WOT logs and 2 Transient Throttle Logs—both conditions are having the same issues but throttle closures are much more apparent on Transient...


2016 340i xDrive M sport Auto with 15K miles. MODS BELOW:
  • MHD & JB4 BEF (Map 7)
  • x-hp TCU FLash (Stage 3)
  • Running e40 (Verified) fuel
  • VRSF ***-less **
  • M Sport exhaust
  • Agency Power intake
  • BMS Stealth Meth kit (100% Meth —> DUAL BM7 Nozzles)

As you noted, your trims are ridiculous and your meth does not appear to be spraying properly (those two issues are probably related).

Try the "Purge" test on the JB4 app using Map 7 (disconnect the hose from the meth nozzle first). Does it work?

I think we got that you are running JB4 latest firmware and using Map 7. What BEF did you flash with MHD? It's not clear from your post.

The meth system has been FULLY tested and is working fine.

I listed the JB4 BEF firmware version in my post "ver.58/13/5".

Did I miss something in your logs? Your meth spray was not 100. Someone else correct me if I'm wrong, I'm only trying to help you.

"ver.58/13/5" is not a BEF, it's the JB4 firmware. BEF is a flash tune, so what BEF file did you flash with MHD?

First issue is you've partially disabled the meth kit, maybe accidentally? Uncheck WMI PWM control on the WMI page. Alternatively if you want to use PWM control then enter a PWM profile under fuel bias. Maybe all 100 is a good way to start. They are all 0 now.

Then relog map7.

Thanks for the guidance, Terry!

See attached for the relog of map7. Also, I have been getting 2 error codes ["123511 Wastegate Flap Sluggish" & "120408 Reduced Power Mode"] that are causing a "drivetrain malfunction" limp mode every time I do a WOT Log.

FYI I am not sure if the drivetrain malfunctioning is due to the Wastegate flap issue or due to the stage 3 x-hp as I flashed both at the same time and then started to log after the 50-mile—recommended by x-hp—transmission adaptation period had lapsed.

Does your purge function work correctly? Does it shoot out a strong arc of liquid?

Yup, I have tested thoroughly, purge works and the atomization is perfect.

Hmmm email in to support. If it’s not air in the line, it might be a hardware issue. If it is, get your voltmeter ready, you will probably have to measure voltage at the jb4 fsb pins, at the 12V switched power line, and at the pump.

Happy Mother's Day!
I'm not sure how many of you are still running the BEF, but my logs are starting to look great. Received a file from Terry about a week ago and after driving on it for a couple days things are starting to positively move forward. Currently running E40 with 100% meth injection and a few other bolt on's. B58 is going to be one hell of a beast once everything is finalized. Looking forward to installing a Pure stage 2 turbo by next month

Changed my mind on the Pure stage 2. Just going to stick to the Pure stage 1 to give it some top end power bump....i think the B58 will be perfect around 520whp-540whp.
