I have the full harness to run including new rear door harnesses.

You dont need to replace the entire door loom, pry off the 2 speaker cable from the donor loom and slot it in in your current harness. I just added that step in my guide

Following steps are needed.

1. Change your VO. So if you had $676 (HiFi System) in your VO remove it and add $677. Check this tutorial for it http://nutsofamily.com/wp-content/up...-CHANGE-VO.pdf
2. Then you have to code cic. Change the parameter AUDIO_SYSTEM_CIC value to top_hifi. Use NCS Dummy (http://revtor.be/ncsdummy/ncsdummy.pdf) and NCS Expert for it.
3. That's all with coding.

you can use INPA to test the Amp. You can play a test file on all or on each LS and verify everything is working.

When you choose Logic 7 Amplifier as marked, then you can runt tests. It is called Enable or similar. I can not enter the menu, because I am not connected with the vehicle.
May be your amp is quit new, then it would work out of the box with cic. Just try it. I can also do remote coding with your, if you have internet at the vehicel.


But note. My CIC had the newest firmware with coding index 1A and the Logic 7 Amp was from 2005. So I had no sound from CIC. I had to flash Amp with WinKFP with the latest firmware. It took 10 minutes and then it had worked. If you have to update your Amp's firmware, it is also not a problem and I will give you steps how to do it.
Firmware upgrade is not needed for testing the amp with INPA. So Code the VO and CIC then if you have sound great and enjoy it. If not, test it with inpa. If it works, then we have to flash Amp. If you can not verify working Amp with INPA, search the wiring problem.

Do you have to to do this even if I have a amp that came from a logic7 car ? I have the amp and head unit and all speakers and wirings.

Do I need to do All this coding if I have the head unit and amp with wiring harness ?so currently here is my situation. I have replaced all the door speakers and the rear shelf speakers with logic 7 speakers on a hifi amp they all work. I plugged in the head unit from logic7 car and my sound disappeared but I was able to go through all the options surround sound etcc.. I figured there Is no sound because the stock hifi amp is still in. Basically I’m em wondering is my assumption correct that when I install the amp the head unit will give our sound the options work I swapped my stock hifi head unit wit logic 7 and was able to go through settings just no sound. Please help I have 0 experience with wiring and speakers I work on the mechanical side of these cars lol.

Hi Rabey.

First thing to note is that The Hifi setup is different from the Logic7. You can't just swap the wiring and expect it to work.
The Hifi amp get the analog signal from the headunit, amplifies it and send it back to the respective speakers. Logic7 amp in the other hand, gets MOST (fiber optics) signal from the headunit, amplifies it and sends to the speakers.

I am suspecting you are missing the fiber link between the headunit to your logic7 amp. Has this been installed? After that, the car will need to be coded with L7 option, otherwise the car will not recognize the L7 amp.

Cheers,
Vicky

Hello, is it absolutely necessary to flash in winkfp Logic 7 amp after retrofit from hifi? or is it enough to code the logic system 7 with ncsexpert?

I have m-ask2 navi.

Is it vital to do the VO code aswell as the Cic coding ? I have changed to top hifi but still no sound

My case is different, I have a m3 e92 with L7 from the factory, with an old alpine OEM professional head unit without a screen I want to change the dashboard I have installed cic UH screen 8.8 and idrive controller I have all the parts, I just don't have sound
I must enable the hifi audio in the CIC I understand, what else should I do sorry for the translator I speak Spanish

[ctuna]

Hi Fi is not Logic 7 .

The amplifier and wiring are totally different.

You’ll need to encode the CIC with SA677 (Hifi Professional DSP). That should give you the correct settings in the CIC. That requires modifying the VO with SA609 (for nav), and the default coding the CIC. This assumes that you didn’t retrofit Logic7 as well.

Are you sure you don’t have BMW Individual Audio (silver speaker grills)?

tnks !!!!! the cic i got was from another more modern M3 with logic7 and hifi enabled i could read it with the diagnostic tool
still no audio
does not have individual audio with silver bars on the speakers

Hi Fi is not Logic 7
Logic 7 is top Hi Fi option 677 or 688 not option 676.
Do not confuse Hi Fi with Top Hi Fi they are not the same.

Maybe it will be helpful if you can inform what you have done on the car so far.

Apart from coding the VO, after that did you code the CIC?

If im not mistaken, E93 has 5channel amplification as opposed to E90/E91 which is 7 channel amplification. The muddy sound is probably due to this. I sure hope the pinouts are identical, which you can attempt to default code the E90 amp to work with your E93 now.
But first check on the equalizer setting to make sure there is no wrong setting like BASS at Zero etc. Confirm that first.
then do the below steps to re-code the amp:
Steps:
Load NCS expert, use Expert profile. Choose your chassis, Process ECU(This will be the AMP) , Then Click Job - Change to SG_Codieren and Execute

Hopefully the signals are reverted back to your E93 setting instead. If you are still hearing muddiness, i would suspect the E93 L7 amp has a different pinouts compared to E90. But im not sure, need to confirm with AMP diagram

hi! i don t know if you are anymore here but i would like to know how to update the amplifier, it is for an e60, i got also cic, still not coded but i think it need updated too!

Hi Vicky, do you know how to update amplifier?

I have not done it myself, but I do know it requires a pricey ICOM cable and a powerful power supply to perform the update.

I installed it yesterday and coded and worked on cic, no need for update
