When on Map 4, does any logic/settings change other than boost target? N54 when using JB4 + BEF.

I doubt it, mine varies /fluctuates a LOT. I tried a different value in offset and I thought I nailed it. Then it went wandering around with the same fuel in tank.

Only if your JB4 boost target exceeds the flash boost target. In BEF mode map4 is hard coded to around 8psi as a low boost / safety map.

It's in the production firmware and is generally around a +-10% variance, and is fulfilling it's intended purpose. To give the JB4 and user a ballpark of their E85 mixture without having to add on any additional hardware.

Default D P Fix - 05-03-2018, 06:09 PM

When I'm running the D P Fix with the JB4, does it matter what map I'm in or whether or not I'm running a BEF to ensure the car shows a ready status?

If I set a duty bias of 60 across the board (needed more for old turbos), does that also apply a modifier to the menu 10 and 12 values or do those remain absolute?

Terry, are you going to fix the can flap issue.

this issue has been going on for a while now, I hate to go backwards in firmware.

A lot of people are having this issue. mine personally is that I toggle the off, however whenever I exit the menu by going back to 0 it opens back up. personally I don't like the drone exhaust sound and hate that this has not been fixed yet.

Running JB4 on my 2010 e90 xdrive. Failed Illinois emissions even with map 0 enabled. Testing station claims they could not get a signal from the ODB2 port. Any option other than removing JB4 to pass? If removed, do I need to drive around to reset anything?

In stock operation the DME opens it as it sees fit. Have you tried going to map0 (disabling any JB4 CANbus operations) to see if it closes? If not, the DME is programming it open.

Thanks Terry,

I see what you are saying even with it on Map 0 it still stays open.

Not sure what the problem is this just started happening. I am running your BEF as well, maybe MHD has some value that is automatically included however I do not even change any of those options when I flash, I just do a straight flash of the BIN.

Do you have any recommendations to make the DME close the valve under normal driving as it has in the past. I do not like the droning exhaust note.

If it's never closing, then maybe a vacuum line issue or some physical issue there.

I have a 09 335xi with DCI and castles DPís. Have it set to map 5 and Iím hitting about 14psi everything seems fine but seems to lack power and occasional overboost code. I noticed when logging that my throttle hit 99 as soon as I first floor it then drops back down to 23 while the pedal is still floored. I have the feeling it feels underpowered because Iím building boost to the solenoids but throttle is actually closing to 25 percent and not letting the air in. Any ideas I set al my settings to the default settings. Checked for any boost leaks too.

Post up a log in the support section with your mods and fueling used so we can help diagnose your car. Get a log from 2krpm-redline in 3rd gear for best data.

Hi Payam, of course no lights now...was driving for an hour, switching from map 1 to 5 to 0 and no light now
hmmm...I have a long road trip coming, usually I experience the problem when I am cruising at 80+ and switch from map 1 to fully disabled. I will have to mess around then to see of I can get the light to come on.
thanks for your help.

Another question, if I update firmware from when I bought the jb4 a few years back , will my gas mileage change say on map 1?..I currently average
24 mpg (hand calculated) at 80-90mph and really enjoy having that kind of mpg but still a super fun car.

Just posted updated firmware.

T2) Adjusted boost safety system so that boost safety for map4 (stock boost profile) change over is 3psi over map target OR 1psi before sensor runs out of range. Whichever is lower. The user adjustment boost safety setting is now used only for in dash boost gauge calibration.
T2) Fixed another bug in the 2STEP logic. Seemed to be working much better on our development car. Let me know!

Firmware changes shouldn't have anything to do with that, I would update it.
