F20/31 hifi amplifier coding
As it looks that my Mosconi amp is dying, i like to replace it with BMW hifi amplifier (hifi NOT TOP hifi). Because low price.
I'm a bit confused if there is CAN in those or not. TIS says that after 2010 hifi amps are not with CAN, but is it or not? The question cames from that F20 amp (available for very low price) is with different part number than F31, meaninfg DSP settings inside are probable different. Electrical connections 100% same. So I'm thinking if i can code F20 to F31, but naturally CAN is needed for that. Any experience? |

RE: F20/31 hifi amplifier coding
I have F20 AMP SA674 in my F10 car. All is possible. This AMP is Plug&Play to HIFI AMP SA676. Only CAN2 is needed. This AMP is F20 car series and you can't flash or code to F10 (F31).You can't find SA674 on this cars. I have coded as F46 DSP. Room and speaker arrangement is similar to F10. Better sound and power like SA676.

RE: F20/31 hifi amplifier coding
Ok, that sounds (literally) good.
I have never noticed that there is 676 and 674, allmost the same, but not. 574 have thicker power wires in WDS which also sounds good. F31 and F20 belongs to same group, so I wonder if I can code this to my car directly (F31). I have allready CAN2 in REM and RADON in left side of trunk, so even wiring should be very easy. Speaker (and input) wires are allready there because Mosconi. Comclusion: I will not spend time to my Mosconi, but order this F20 amp. EDIT:found one with just over 100€, bargain! Only to find out how to code |

Better sound and power like SA676. I have coded several things last 10 years, but never like this. How can I code something that does not belong to my car? Select "wrong" car in esys and read ecus? I will have amp at the end of week or early next week, do time to study. |

I have installed SA674 on the F36 in 2018. I need to add the kcan line to enter. The encoding is encoded in an abnormal way.
amp have 360w and 410w |

RE: F20/31 hifi amplifier coding
For coding must load a F20 car VO. Only in this kis db ESYS will find the cafd.

RE: F20/31 hifi amplifier coding
Enetough I still don't have the amp, I a bit tested with F20 VO files i have. Looks relatively simple.
Even in my F31 entrynav there I can choose directly hifi HK, so not TOP hifi HK, which is also naturally there. That previous one should be the right. Wonder what makes difference to normal hifi. Then. I assume there are only bass & treble controls, not equalixer, right? |

WDS shows that there is RADON in left side of trunk behind cover in noise surpressor input. But there are only yellow and black/ yellow wires without satisfactory voltage. RADON is black 0,35 mm2, but where the hell is that? Currently I connect temporaly wakeup straight to REM. |

What is the name (eg HU for headunit, ACSM for airbag etc) for this HK hifi amp Iin ESYS ecu list? Coding, how excatly it should be made with ESYS? |
