Anymore feedback on the new JB4 5.14 firmware?

It seemed pretty good on the way to work this morning. I didn't notice anything weird or different.

It works fine for me,
1 thing i notice is that when i plug in my Dcan cable for MHD
My jb4 switch to map 0 by itself, ? it never did that.
Can i change this ? cause they try to steal my car trough the OBD port already but did not succes thanks to jb4 but now when they plug in the OBD port they have free acces cause jb4 switch to map 0 by itself ...

Major difference for me in part throttle, especially on hills when it needs a higher load.

Flashed back to MHD only to see if it was smoother and it was not. This is just as smooth, but a lot more power all around.

Will there be any drawbacks to sending a full ECU PSI signal back? I know you mentioned could be some mid throttle issues, but have not encountered any in about 200mi so far. I'm sure there was a reason to have it half signal before..

I think the PWM difference at full throttle on yours was from the new FUD settings being different. A value of 99 would be triggered several random bits.

Yes this is a safety system we added to prevent flashing headaches. I guess we could add a FUD option to disable it if you are using the JB4 as a theft deterrent device.

Like any tuning its a balancing act. So far I've been happy with the transitions I've seen in logs. We run a similar approach to how we handle the N54 BEF. Frankly it was just an oversight that we had not added this to the N55 JB4 BEF firmware yet. Glad you prodded around there to help isolate the issue.

You shoulda gone for the xDrive!

Seriously though, cold air, salty roads...I'm finally getting some traction action. Normally you can't break it loose without doing something foolish.

Terry, I loaded the new firmware after work today and put some miles on it. So far, so good. Feels smooth and strong. Will need to give it a few more days to know for sure. I saw you mention transitions in the logs...you looking for part-throttle logs or just regular WOT pulls?

For logs mid to heavy throttle unless you have an issue with something not being smooth down low, in which case uncheck log wot only and capture it.

JacquesN55, I believe that is just a display issue. It still works correctly even though it displays incorrectly (Terry correct me if I'm wrong).

Terry, here's a log I grabbed on the way home last night.

Meu11 is a display issue but every time you check it it would save half the value. Anyway, it's fixed now.

Could be, the Cobb had inaccurate timing formulas in it. One of the many reasons we no longer support it.

Just giving my feedback on the 5.14 FW and adjusting menu 11.

I didn't know that menu 11 changed from FOL to pedal sensitivity with the BEF FW, so running it at 0 until yesterday. There was nothing linear about it at 0, just crazy lag. I am now at 4.5 for menu 11. I overboost now at tip in, but am working that out.

Before FW 5.14 and setting menu 11 to 4.5, I would be very rich at spool up and the first half of the pull. It would correct to the right AFR by the end of 3rd gear, shifting to 4th. Now that I am on FW 5.14 with menu 11 at 4.5, I no longer go rich and have no "lag".

For part throttle, everything is better. There was a dead spot shifting from 2nd to 3rd at 3k rpms before, now it's gone. There also was a lurch when accelerating from a stop, also gone. So big plus all around.

However, on 2 occasions while accelerating at 50% throttle, I've gotten massive backfires. It sounded like the PPK exhaust burbles on extreme, while accelerating. Didn't get a log and cant replicate when I try, so have no clue why it happens.

I have also experienced a sort of backfire since running BEF firmware. Oddly, though, it sounded like it came from the **. It's only happened a few times, usually coming off heavy throttle/high rpm, and varies in intensity. Scared the crap out of me the first time...thought I blew a head gasket at first.

I have settled on 3200 for menu 11. Higher numbers yield stronger response but also makes the car jerky and, between constant spooling and blow off, the turbo was making a lot of noise. So much so that it was getting annoying. Can't be good for longevity.
