Base stereo to HiFi recoding success?
Hi guys,
I have successfully coded a few options as Digital Speed, and Tv in motion, on my 2006 CCC (no navi), but with TV option, so I am grateful to all of you, for that Now, I am trying to recode the audio from stereo to hifi. I added $676 to the CAS, but I haven't seen any change in the rest of the modules (CAPPL, CAUDI, CGATE). I also tried to replace e90_stereo with e90_hifi in various places, and the coding has been always successful. My question is: how can I tell that I really did it, as I am unable to notice any sound difference (I still have the base system installed, no changes, yet). Thanks for everyone's contribution to this forum. |

I have seen in other threads here
I have seen in other threads here on the same topic . That if you
press some buttons on the head unit it displays in text what its programmed to. It might have been in the stereo section in one of taibanl posts. If you were successful the volume should have dropped a lot as they are now low voltage flat signals. |

Thanks...
so I guess I should burn a cd with a constant signal and play it, then code/recode and try to detect a change in the volume?
How about using a voltmeter, can someone guide me on that? Where and how to meter? |

You must notice the difference as it will be very obvious, especially the volume level of the front speakers/woofers being in parallel and with a low level signal driving them. |

Thanks,
so I removed the $676 from VO from CAS, I recoded without the .MAN, so basically I restored it to stereo.
Then I re-added $676 to CAS and FRM (with FW_WRITE), and then recoded the CAPPL/CTUNE/CGATE/CAUDI with default. The result was that the CAPPL/CAUDI now have _hifi all over the place, instead of _stereo. So I am missing something... Maybe another option paired with $676? |

quiet gongs
Today I noticed that my gongs (seatbelt, door open) are very quiet, which makes me hope the coding was successful.
So I am going to measure the AC voltage either to rear speakers or to underseats, see what I get... Just thinking out loud... |

Did you use voltmeter, put it in to DC mode, connected it to wires speakers and volume to max to see the results?

Hi,
I am trying to do the same, added 676 to VO, FA write the CAS and FA write the NFRM (don't have the FRM). But trying to write an empty man file to the CAUDI gives me an error job not found I believe. I have a 12-2007 e91 with Navi pro. any ideas? |

Write those modules with expert mode, so they revert back to what they should be with new VO.

Hi,
Thanks for the answer, how about writing in expert mode. Just read ecu and then sg codieren? Without modifying the fsw_psw file or saving as man file first? I found out the car needed to be shutdown for some minutes. So after 10 min. I went in the car and found out gong, pdc but also sound pressure was much lower. So programming to hifi worked but all was low level now, also the rear speakers I believe. It will be nice to have rear in high level (high pass mode if possible) and have the front speakers flat high level outputs because my amp takes this signal at the moment but have the gong and perhaps pdc send low level signal because now it is to loud. Any idea howto do this. |

is having a CCC without navi, but with a TV Module installed, which allows you to ... watch analogue local TV stations, on the screen. Can also be coded to run during motion.
Is there anything specific you want to know about? |

I don't have a lot of experience (more of a noob, myself), but I would search more for how other people managed to keep a low gong. |

I coded my 2007 E92 with CCC and the Alpine retrofit for hifi by adding $676 to FA in CAS and FRM then coding CHOST, CAPPL, CGATE, CAUDI and CTUNE in Expert Mode. You definitely get a boost to the midrange and I didn't run into any of the problems experienced by others regarding PDC and Bluetooth volume. However, three things to note:
Hope that's of use to someone!

Hi All,
Thank you so much for this thread. I have been mucking around trying to code my car for a while. . . .I have now got there. I installed a series of stereo upgrades some time ago, which you can see here under other threads. I have always been unhappy about the volume of the gong and some interference and I have just managed to code $676 to my E92 thanks in part to input on this thread. I am very happy and at the weekend will now re-configure my Vibe Litebox amp to best use the new input levels. These are not now line level inputs are they? Thanks again, |

Hi all,
I have a 06 e90 325i and just got Alpine retrofit installed by BMW. The kit is good but its really boomy. I have idrive with Business Nav and looking to code it to hifi. Is there any one that can provide any help on how I can do this or point me in the right direction. I am really new to the coding side. Thanks |
