I think HIRRS-ZN is referring to the inability to tell which firmware you are on once it's loaded. The firmware in the csv file is more like a date code.

In that case...
58/9//5 = BMW_B48_B58_OBDII_9_T4.hex

It was confusing to me in the beginning as well. lol.

Awesome thanks JBoe,

So seems my Jb4 has the latest Firmware

On another note, i just tested the car with the JB4 on Map1 and noticed very bad hesitation from 2nd gear wot. i was using Sport Plus Manual mode (Sport Auto Box) i switched to Map 0 and theirs no hesitation. Switched back to Map1 and switched to Sport Mode Manual which seemed smooth as well. i then switched back to Sport Plus Manual and the hesitation is now gone seems smooth. Could this be the car was still adapting to the JB4?

Terry, I have uploaded a few logs i tested with. please could check them and advise.

Thanks,

Hi Terry... is it possible to add the stock/default WMI settings tab to the first posts? I did some digging and found them, but it would be great if they could be included.

Default Looking to purchase - 09-16-2018, 07:37 PM

So long and crazy story but I have 2018 440xi with MPPSK. I had dinan stage 1 in my car installed by dealership and apparently it blew my turbo. All was covered by warranty but they removed the dinan and refunded my money. I’m missing the power and was looking to purchase JB4 to supplement the loss. Having the M Performance Power and Sound (MPPSK) package is the jb4 the only needed product or should I use flex fuel ewg and so on?

Interesting info. Get all wires and log like crazy. The JB4 will not over work the turbo unless you're doing something seriously wrong. But I like to verify with logging.

Thank god for that warranty coverage, though!

Log, log, then log some more...

I found one of the causes and an easy workaround so I'm sharing my experience here.

In short:
Basically Engine DME boost map changes with driving mode (sport/comfort) and the same JB4 map won't work well in both driving modes. A work around is to deactivate in the Idrive menu from the car the changes de DME make to the engine in sport drive mode so the engine always runs like in comfort mode independently of other driving modes changes and a consistent jb4 map is easy to achieve.



The cause:

Engine boost by rpm changes with driving mode (sport/comfort/eco). In a wot pool in sport mode my 20i gets a flat 7.5 to 8 psi boost from low to max rpm. But doing the same in comfort mode I get a flat 4.5-5 psi boost with a 7.5-8 psi peak at 4500-5000 rpm. That is almost a 100% boost increase from 4000 to 4.5 psi)to 4500 (8 psi) rpm that the jb4 seems to have trouble compensating for (overshooting and over correcting= oscillations= not a nice ride).

So you can work on a fine tuned map 6 on sport mode, using duty bias to adjust de FF curve by rpm to mach PWM, using just the amount of PID gain to allow small corrections without oscillations, etc, and the car runs smooth and fast (huge HP difference from original 8 psi to flat 16 psi in the 20i). But the moment you switch to comfort mode or you restart the car and forget to switch back to sport and accelerate the engines DME gives a completely different boost / rpm curve and the jb4 goes crazy trying to adjust with the known unpleasant result.

Maybe this engine needs two maps, one for sports and one for comfort mode.

Work around:
1) Make a custom map 6 for comfort mode (or just keep with maps 1, 2 or 3.

2)In cars idrive menu go to Sport mode configuration and deactivate changes made to the engine but leave activated the other options (suspension, gears, driving wheel stiffness and gas pedal sensitivity)
Currently I found a limitation. Its “easy” to make a map 6 for sport mode (we start with a relative flat DME’s BOOST curve) but its difficult in comfort mode. Max Boost / RPM changes so abruptly between 4500 and 5000 rpm that current available duty bias range at the JB4 (I’ m using from 0 to 100 values) is not enough to cover the needed FF/rpm curve and using PID gain above a value of 10 trying to compensate might bring oscillations.

It would be great to have a custom map or even firmware for the B48 20i and if not possible at least to have a wider duty bias range (for de 20i 0 to 170-180 would be enough, maybe allow negative values).

Hope it helps, Jorge.

Here you have a pair of stock logs on map4, one @Sport and one @Comfort, to evaluate boost difference, hope in helps to make a more "fluid" driving firmware. The car is a 2017 320i with a B48M engine.

Hard to remove without damaging them, better off cutting and splicing wires if you placed one in the wrong spot.

I know I can vouch that. I purchased that D removing tool from Frys electronics yesterday and it didn’t work. I’m sorta like a ‘perfectionist’ so I wouldn’t be able to sleep well at night if I don’t get that pin out the wrong spot
I guess no EWG pigtail for now...

Not all D-Sub tools are alike. Some are specific to various sizes and others are generic install/removal tools. You may be able to find better than what Fry's has available. Of course... you'll probably only use it once. LOL.

Default Map selection - 09-19-2018, 02:04 PM

Hey guys I have a 2018 440xi GC with MPPSK just received my JB4 today installed and set to Map 2. Was feeling a lot of hesitation. Is this because the car needs to adapt? Also for having just mppsk which is best map to use? Also using 93 octane

Could be adaption or could be fuel related. Drop down to map1 and record a JB4 log if issue persists.

Finally have one of the B58 cars with the latest update that won't clear codes here for a few days. Hopefully, can make some progress on this annoying problem!

Added 11_TEST1 to the first post which seemed to allow me to delete faults on our test car. Let me know if it does or doesn't work for anyone else.

"Adjustment to absolute target mapping, lots more testing needed. Send in some logs if running absolute target maps like map7."
So you're also looking for input outside the fault-clearing issue, then? If so, I'll give it a whirl.

Yes, the absoute map stuff needs some logs. It's not quite finished yet but it's included in the latest build along with the code delete fix I'm working on. The changes there mirror what we've done with the S55 absolute target maps. Smoother operation, allowing targets less than the flash target, etc.

How much of an issue is throttle closures with JB4 and B58 nowdays?
Im just replacing my N54 with a B58 and did some reasearch and found out that jerky operation due to throttle closures was a real issue when running JB4.
However the information i found were from the early days for the B58 and JB4.

I also read in the patch notes that JB4 can control timing, how is that possible on the B58 since from my understanding JB4 only controls boost and fuel pressure for the N54 and N55?
