Default N54 Malfunction when using JB4 map - 06-08-2019, 09:42 AM

Hi Guys,

I am really running out of Idea and don't know what to do anymore.

I've never had issue with my car since last week. When wot in map 3 running Racegas BEF my transmission is acting wierd, when trying to shift it will overshift or go on neutral and sometimes after it shifts it will downshift. It hapenened after I installed my precision coil kit. I was sure it was the tranny oil or valvebody so I replaced the seals and tranny oil but no success. Then I replaced the whole tranny with body valve (keeping the old mechatronic so I don't need to reprogram ) and my tranny is still doing the same thing. Then I tried to reflash my XHP and still the same thing. So at the track yesterday I tried map 4 and everyhting was fine this way. Map 1-2-3 are all causing my issue. I a not sure anymore, is it jb4 causing this? Mechanical part not taking the high boots? Mechatronic failure?

I need help please. There is a log I did at the track with map 3.

Thank you Guys

Any codes? I see it misfired or something and went lean, and the JB4 disabled for safety.

Those are the only code I got otherwise it will not throw any code.
My gears are going nuts in this log!

Misfire can make the car buck / run very rough.

I’d addres the misfire 1st- then let’s get another log.

Hi Dave, thanks for the answer. Do you think I should remove my pr coils and go back with oem for testing? My spark plugs are brand new and new oem coils also. You think it would only missfire when using map 1-2-3 but not in map 4? Also this is the only time I had a missfire code after several try, car is bucking every time but no code. Thank you

Yes post a log of map1... Map4 is low boost, so that makes sense, transmission issues are normally power related.

Here you go, I went smooth on this one but hard enough to get the gear malfunction error to come up.

Was the trans used ?

Are you using stock trans software or xHp, alpina or anything?

Reach up behind your front junction box (fuse box) and make sure the E-box cooling fan is working. The JB4 adds a lot of heat to that box and it's a poor cooling design at best. The fans can fail with no codes and a hot DME isn't a happy DME.


No matter how fast I go there's always someone slower in front of me.

The transmission was used but low milleage and tested, also doing exactly the same issue as the one before with higher milleage. I was running ( without knowing ) XHP with an old version, I am now running the newest version of Xhp (still the same issue) but their software is bugged and can't reload since I resetted my adaptation, they are not replying to my email. Yesterday I tried to reset my adaptation and recalibrated everything as mentionned in the file software + T re-adaptation and hope it will solve my issue. I will drive the car smoothly for anoter 200km before trying to push it hard.

Thanks a lot for your time guys! It is greatly appreciated!

To be honest I had no clue there was a fan in there, I don't remember seing one cooling the dme box. I will double check to make sure there is one in there? Also, is there a temp sensor to allow it to run when needed or it should run all the time?

Thank you !

Terry and Dave, from my logs can you see if I am running out of gas pressure or flow? I was thinking maybe this would be the problem?

Thank you

The fan is inside the car and well hidden behind the 'fuse box'.

The speed is controlled by the DME. When cool it runs slow, then speeds up as the DME heats. Another problem is the carpet might be covering the air inlet a bit. If you want to confirm it's heat build up in the DME, take off the E-box cover and give it a try.

I spent nearly 2 months chasing the same trans problem in addition to my WMI coming on unexpectedly and flooding out the engine.

That log is extremely short- but again the HPFP / LPFP values look fine.

Dont think you have a fuel delivery / pressure issue.

This looks like a physical hardware issue w. the trans imo
