It was doing it on stock coils so I upgraded recently as my last resort. Iíve tried bb flash after a custom tune and still misfiring. Even on map 1 with or without meth. So yes on lower boost it still does it. Logs are fine according to trebila.

Hey all,

I just flashed the IKM0S ROM from the 1M to my 135i.

I then flashed the IKM0S BEF that's included in the BEF pack. (you have to change 2 bits so that it runs on the 135i with the 1M ROM).

The car drives awesome, throttle response is like a cable throttle now.

However, now I'm running IKM0S, I'm having trouble getting the JB4 to log IGN on 6 cylinders.

All I can find is, set 6 cyl logging to:
4 for I8A0S
5 for IJE0S

What do I use for IKM0S?

Thanks,
Tim

This is brilliant.
What ROM were you before the flash.
And what bits did you have to change.

Care to share the process of the ROM update?

I am on IJE0S at the moment. 335i N54 DCT.

If you're MSD81, then it's actually super easy. If you're MSD80 you will need to change the DME over.

Use WINKFP to flash the 1M Rom to your DME. Edit the IKM0S BEF using the XDF definitions in the e90post link. Then use MHD to flash your modified IKM0S

BEWARE: You cannot use an MHD OTS tune, only JB4 BEF. You can also use your custom tune but you'll have to port it over to IKM0S, or your tuner can do it for you.

Well worth the effort in my opinion, it's a free mod for most of us who already have the tools!

I don't see why you'd want to change when you can just adjust the throttle filter map as mentioned

I have tried to search answer to my problem and how to fix it but I haven't found. Here is some log of My testrun. So the problem is overboosting after shifting. The target is 17psi but the boost is spiking to 20psi after shift. I have tried to adjust little bit "auto shift boost redux" from jb4 but no results. I have jb4 map2, bef (pump) and 3ĒDP. JB4 user adjustments are now in stock values. I think this problem started 3 weeks ago when I did mhd bef but is it possible to limit that overboost after shifting from jb4?

any real power or advantage on updating the ECU from IJE0S to IKM0S. or its just the feel that newer is better? ( no in all cases newer is better anyways ) sometimes newer is better for manufacturer and worst for tuner and modification.

Do we need to access the dash menus if we have the android mobile app?

I read the first FAQ post and description.

I have a custom BEF from a performance shop, I get a 30ff code when i try and accelerate at highway speeds to pass and the trans does not downshift to accompany the added pedal input. It will only boost to about 2psi.

Was wondering if the menu setting wasnt activated to tell the jb4 I have a bef

Terry I really think you should consider adding the restore defaults option back into the interface. I've seen a lot of people who upgrade from 20 series to 30 series firmware have a lot of issues, even after manually resetting the user adjustments. Same for people who buy used units. I think there may still be some bits flipped somewhere in the back end that need to be reset. Maybe also a better way to identify G4/G5, and ISO/non-ISO for people with older boards.

Below is a link showing what I'm experiencing with updating the JB4 and then adding a BEF a day later.

For outside the USA use that can be sorted in the MHD BEF.

Question for the jb4 experts.... Iím currently running the latest jb4 firmware and the mhd BEF. Iím now running map 2 with e35 and iím getting the targeted 17LBs (I only get 15.5 on map 5). I believe map 2 works fine and will still target 17LBs with 93 octane. Is there any benefit to running an ethanol mix with map 2? Would it be accurate to say map 2 only down-tunes if there is an issue such as knock and that map 2 will not up-tune (add timing or anything) if a higher octane fuel or ethanol is used?

Map5 will adjust based on historic timing feedback. If map2 is running well then running a fixed target can certainly be faster. I'd have to see the map5 and map2 log to see why map5 is detuning itself for you.

Terry,
I will include a few logs.

1st log 5-23_1639 - map 5 as I have ran it for years on jb4 firmware 28_02. I think this was running e40. I typically got 15LBs with around 10 degrees timing.

2nd log 6-12_1807 - map 5 after upgrading to the latest firmware on 6/12 also running e40. For some reason this was targeting 19LBs with around 10+ degrees timing. I didn’t think map 5 would target that high. The car was a lot faster but maxed out the trims and ran lean (in one log it hit 15.4 afr at 5,300 rpm). This kicked me to map 4. I didn’t run the car hard again until adding the pump BEF.

3rd log 6-14_0902 - map 5 after adding the pump BEF running e40 on 6/14. The car ran around 15LBs, but with much lower timing than it ever has before. This was the slowest the car felt in years.

4th log 6-15_1736 - map 2 running e40. which appears to run pretty consistently around 17LBs also with the lower timing Since adding the BEF. Looks like this will require an upgraded lpfp while running e40. I probably wouldn’t need the lpfp upgrade if I ran 93 octane. This might have been close in power to the first log.

I started making all these changes because I was looking for a little more power. I’m not sure what to do now. Map 5 with e40 no longer seems like an option after the firmware update due to trims unless I lower the ethanol content. Map 2 with the new jb4 firmware and the BEF feels similar to the old map 5 before I changed anything but looks like I will need a lpfp based on some of my logs. I’m hitting 50 on the lpfp before 6k rpm sometimes.

I understand the RACE BEF has better timing values. I know it says for use with higher octane fuels. Is it ok to run the race BEF on map 5 with 93 octane or e40?

Sorry for the Long post. Thanks for your feedback.

Default Upgrade Firmware? - 06-16-2019, 09:29 PM

Hi Terry,

Have been using JB4 for about 3 years, havent updated my firmware for awhile. Was wondering if I should upgrade to get better performance? I have attached my log for you to take a look. Please advise. Thank you.

He wont be able to tell you much based on that log. Try to get a log where you go full throttle from 3k rpm to 6k rpm. It looks like you only stepped on it for a few seconds.

Any feedback on my post?

I don't like any maps on the backend flash and the most up to date firmware on the JB4. I think I will remove the backend pump flash. The only issue with that is the JB4 with firmware 32_14 seems to be too aggressive for me to run ethanol like I used to on map 5(trimming issues). I don't know that it is normal for it to target 19 LBs and 10+ degrees of timing like it did.

Is there anyway I can go back to the old 28_02 firmware for JB4? The car ran great for about 5 years on this with map 5 and e30 to e40 before I got the great idea to update.
