Oh look, free info...

Good lad - better late than never.

Found it and changed it I'll see how that is now.

What was it set to? was it just on stereo?

I did the speaker swap the other day as well as adding tweeters. Just done the coding but when I first went on audio system it shown variant01, 02 etc. Changed it to variant03 so the werte valued shown 02 and saved the changes. Logged back know in to check it saved OK but this time it shown as standard, hifi etc, changed it to top hi-fi and werte was 02 saved it again logged out and back in, this time it saved correctly. Any one have any ideas why it shown varient01 etc the first time?

Is that all that needs changing when changing the speakers?

Yes it was on stereo so I changed it to hifi and it's miles better.

What's the difference between top hifi and hifi

I assume hifi = advanced and top hifi =HK?

I would be interested to see them Matt.
Just installed the Focal BMW upgraded mods / tweeters to mine yesterday.

Hi all. Can this coding be done using Bimmercode, or is it only with ESYS?

Top HIFI= Digital output
HIFI= Analog with low-level output (through speaker wires)

Stereo=analog with high-level (speaker) output

I had base stereo setup in my F20, but now have upgraded all speakers and added Match PP62DSP PnP amplifier. It works great other than when i coded Stereo=Hifi , the signal is so weak that amp does not always want to start up. It accepts 5v-11v Speaker-level inputs(high level) and i have put gains up to compensate lack of voltage coming now from HU.
This can be solved easily by getting start-up signal somewhere else,so it does not bother me.

I suggest getting better model which accepts speaker inputs with low-level signal.
Best part of this Amp is how easily it can be installed. It hooks up behind stereo connector and gets all needed inputs and power from it. It also has DSP processor which is configured to be used in a car with Base stereo and needs no coding to Hifi or whatever.

I coded anyway, because i wanted to make my own setups using their DSP tool with specs of speakers i installed. just google Audiotech Fischer

hope this can help someone!

If youre coding to Hifi, i suggest you add hifi to FA and VO code headunit. That way your settings wont disappear when car is in service and getting updates to modules etc.

I'm interested in this as well. Seems some have coded HiFi without the low level signal being an issue. Is it possible to flatten the eq without taking a remote in from somewhere?

I’ve just done the Blam speaker upgrade, door and under seats on my F22 M235i Do you think it’s worth coding, obviously I haven’t added tweeters on this upgrade so would it be worth it ? Also planning on using BimmerCode if it is worth the change is this possible .
