My guess is that this amp is also used in the E83 since many of the values can be E83. Since the X3 has a much larger cabin, I wonder if telling the amp it's in a E83 would boost the bass level even more that the E85 value? |

So, holy grail would be to be able to get the 3 different coding profiles used in the e83, the e85, and the e86, set them all up, and sit there recoding the amp to each one, while its in the e86 until you have the one that sounds the best. Ultimately deciphering the code would be nice and all, but we just want to find out what e8'x' to match it to and were in good shape.

i'd use mine as a guinea pig again but i'm already into this project for a few bucks, and dont want to spend anymore if possible considering i'm happy as is. but i'd be a guinea pig if I could do it @ zero cost.

Oh, I forgot I heard sometime in 2007-08 or so BMW changed the communication bus from K-LINE to D-CAN and the $12 cable only works with L-LINE. D-CAN requires a $50-$80 cable, but will also work with K-LINE too. Though, I wonder if BME bothered changing to D-CAN on the Z4 since it was the last year for that body. Too bad you don't live closer, I could try my cable on your car. I'm just on the west side of baltimore. Though not related to this topic, I recoded triple blink turn signal, removed freeze warning buzzer, windows up with remote, decreased service interval from 25000km to 15000kl, remove buzzer for key in ign switch when door opens, activated tilt sensor(which dealer did not do, when they said they did) and a few other things. |

Those are all great coding ideas, I'd do them. I could get into the coding thing but only if I can learn from somone. I could see a road trip to baltimore at some point.
Just occured to me, why don't I swap amps with my wife's X3 and see what that does, rather than a recode of mine again. Very good chance the e83 doesn't work properly, speaker configuration could be entirely different.

Ok i'm finally back home and have been looking into this. From what little I have seen and read on it, it appears to be QUITE a task to actually pull the amp out of an E83. Kinda discouraging for me, so I will probably hold off on this unless I come across someone else with experience on it - or I get a lot of free time and courage.
In the mean time, about to bring the coupe in for its final in-warranty service and check up. Going to yank the amp out of it so they dont accidentally code over it at the dealership when its in for service.

Was good for me too - to confirm the difference. It was quite noticable how significant it is. I'd say its night and day.
e85 amp = excellent stock system overall e86 amp = terrible stock system overall Anyone in an e85 could rightfully make a few bucks offering to swap amps; if they dont mind making a dealership run for a recoding of the e86 amp.

Amp aside the coding suggestions above aren't new. For a while I messed with few options from triple blink, navi accept off, windows down with key fob. The one I REALLY wanted but could not do was disable the amber eyelids. I was only able to disable 2 of the 3 bulbs. Only person I know to successfully have done this is Starscream.
Pungo - if you can figure out how to disable all 3 bulbs please let us know!!! (keeping note of which lines/codes you have to turn off, I went down line by line and still no dice). Last edited by 3002 tii; 04-02-2012 at 11:21 PM.. |

Not sure what 2 of 3 lights are but my ambers (only the vertical one not the bottom row) only come on when I signal. Did that make any sense?

I recoded to disabling the amber eyelids and it worked, only thing is the rear side makers and front eyelid side makers went out too, so I turned them back on. I did this: SIDEMARKER_US PARKING LIGHTS ON WHEN HEADLIGHTS ACTIVATED (USA) nicht_aktiv not active !US Oh, wait, I think I need to do this: SL_VO_ANSTEUERUNG FRONT PARKING LIGHTS CONTROL nicht_aktiv not active |

Now, I'm going to have to recode my E86 DSP module to E85 specs and listen to the difference. Too bad someone can't read their E85 DSP module and post it so I can try it. I'll just have to make an educated guess as to what I need to change, which most of it is obvious. |

we could figure something out im sure. Pungo, any friends in your area with a roadster?
Indeed, sending the amp to someone and then paying for a dealer to recode it there is not what anyone really WANTS to do, but at this point its all we have been able to come up with, unless we figure out coding the way you have. Its great to see that you are comfortable with the process.

I agree that sending an amp is not something you want to do.. However, the dealer has to have it installed in an E85 in order to code it.. The coding process they use is somehow through the ECU and is controlled by VIN number.. They don't go in and change individual values manually.. So I had to take my amp out of my MC and install it in my wife's roadster.. I then took the car to the dealer and had it coded to my wife's roadster.. I reinstalled it back into my MC and now I am rocking!! gtMc was in contact with me throughout this experimental process, and I am happy that I was able to help him with his audio issues.. It would be great if there was another alternative to doing what we did.. If you drive a Z4C or a MC, you should have great audio.. (when you aren't listening to the engine roar!!)

The s/w I'm using is intended for the engineers at BMW, so it allows you to do anything, even recode a E86 module to E85 specs. The module I think that needs to be recoded is called the "DSP_E85.C02" even if it's in a E85 or E86. I read this module in from my E86 and changed all the values that had E86 to E85. I will recode my E86 with this new file and listen to the difference. I have a sound pressure meter that I will use so I can measure the difference besides just by my ears. Did you notice louder bass frequencies when you swapped to the E85 coded amp? Here is diff file showing all the differences after I changed the values to E85. |
