I noticed one push DTC is on the guide twice. Once on 5/5 and again on 6/4. My car worked on 6/4. The rest worked for me. Thanks for the update.

Thanks for taking the time to update that, new jb4 users get mixed up pretty easy and the old guide was off on quite a few settings

Also, I don't know that I can get PPK back after flashing to 2.55.

Here are my Map5 plugs: http://www.n54tech.com/forums/showthread.php?t=37376
I replaced them, switched to Map1, then examined the plugs after a few weeks and found the same timing drops and plug buildups occurring. Next I removed JB4 and installed N20 plugs which looked perfect after a few thousand miles. Now I have Map1 + PPK + FMIC + N20 plugs + Summer heat and so far the timing looks pretty stable around 4 deg but I don't have enough time on the plugs yet so I haven't checked them.

I asked Terry about the JB4+PPK compatibility and if they had ever done any tuning of that combination and what he told me is that PPK pulls down the entire timing curve and JB4 can only reduce timing further, never advance it beyond DME targets. And while PPK increases boost, ISO ignores the DME target. I don't know how the AFR control works but I assume both JB4 and PPK reduce it. If that's the case, it would seem that PPK would make JB4 weaker and safer. Right?
Been flashing back and forth between PPK and no PPK today. No PPK is for sure more powerful with less timing drops and more boost and more consistent. Seems no one really has done many back to back tests

The ppk/no ppk comparison is interesting.

I have a 2013 135is that comes stock with the ppk. Things Ive noticed after each stage of modding are that the jb4 iso and the ppk work well together and run high boost easily. However, this combo really only allows about an e35 mix before it throws "partial throttle too lean" codes. Adjusting FOL does not help. Full boost everything is fine.

In terms of you switching back and forth between the ppk flash, my car takes a solid 100 miles (on top of the 3rd gear WOT runs for the jb4) for the DME to adjust to any major changes I make to the tune (changing boost, using a different E blend, meth nozzle etc.). This may be something inherent with the ppk flash, not sure.

Is ISO 5_11 a new update? I have 5_10. What is the difference?

Default ISO 5_11 menu 11 problem - 07-02-2016, 07:22 PM

Hi Terry, Currently running ISO 5_11 on my 2011 BMW 335i and I found menu 11 won't hold the volume that I input. I tired to set it to 5 but every time I across menu 11 from menu 10 or from menu 12, the setting will drop and after few times that will drop to 0. For sure there is a bug on menu 11 setting.

I have a 2011 e90 with ppk flash and I can run e40 without any codes.

Interesting threads about ppk and jb4.

I run both and have no codes.
Sometimes slight hesitation or jerkiness (hot days for example)

When I submitted my logs for MAP 1, both Terry and Steve noticed it was ok, but timing adjustments slightly off if I remember...
Point being that it would benefit from Ethanol mix and moving the FOL to 70 or so.

Is that related?

I'm not convinced the "PPK flash" you guys are loading makes much difference either way.

Terry,
thanks - good to know.

At the end of the day, codes for me will indicate issues, and maybe issues others are experiencing via those codes would manifest themselves anyway, PPK or not.

Terry,

Is there any way to add fuel during crank?

If I run anything more then E50, I get a hard start. Even in San Diego when the mornings are 70 degrees.

I was reading in this thread of a fix, but it's with the N54 and PI

There is a FutureUseA = 52 option in v5.11 that attempts to add fuel during cranking and low idle. Worth a test.

There is an unrelated side effect with the FUA setting that we'll have to fix in v5.12 if the setting works for cranking fuel.

Terry, am I right in thinking that a few years ago you had a JB4 FW capable of measuring DCT pressue? I'm sure I remember reading something a while back where you were testing via this method.

If so, would it be possible to get a copy? Given the N55 E progress and that we have the option to use different TCU flashes it would be great to have this.

I updated to 5.11 and in the mobile app, under FutureUseA put a 52 and then saved. Is this correct? I did this, and started it to move the car...it was already warm so it started ok.

This AM though, it started and revved really high and kind of bounced RPM's a bit.

It did start much differently. I'll try again tomorrow AM and take a video.

Those pedal boxes are a waste of money but won't conflict with the tuning.

Hello all.

I just purchased a used 2011 335ix that came with a JB4 installed, ********* DP and a Cobb chargepipe.

I hooked up a laptop to the USB port and I see what I believe is non ISO firmware.

Is there any way to tell if the diode has been cut (or needs to be cut) w/o opening the cover and getting to the JB4?

What would happen if I upgrade to the latest ISO firmware but the diode has not been cut?

Thanks.

Is the firmware version listed as 8/17/12//1? I think that's the last non ISO firmware version. You cannot drive the car with the ISO firmware without the diode cut. It will drive like crap. It has to be done at the same time you upgrade to ISO, before starting the car.

Lets try this again... Looks like someone deleted my previous response to you.

The JB4 ISO firmware will not allow your emissions equipment to ready up. That is probably why there is a rumor that you can no longer fully bypass the JB4 with ISO. It doesn't matter what map you put the JB4 to, the car will not ready up. COBB works this way too. It is basically like a built in DP fix. However, the major drawback to coding the JB4 this way is that you can't simply flash back to stock like with the COBB AP. You have to fully remove the JB4! It also means that you will not be able to ever get any emissions related engine codes, like o2 sensor, without fully removing the JB4.

Disabling code clearing has no effect.

Here is the thread where I have been posting the other bugs I have with the latest firmware: http://www.n54tech.com/forums/showthread.php?t=40880

Just noticed 1/3 and 1/4 are blank on the new guide - has the option to toggle 'auto code clear' been removed?

It still toggles using those wheel controls. Why Terry didn't fix those lines when he supposedly updated the N55 wheel control guide the other day is beyond me...

BMS could probably cut the amount of time they have to invest in answering questions on the forums in half if they just updated the/wrote up better user guides.
