Just plugged in on my 2008 E92 M3 - minor coding and voila!

Nice!!

Hello everyone.

I have ran into somewhat of a road block.

I did an NBT EVO retrofit on my 2006 E90 330i which had a professional CCC unit installed, logic HIFI amp.
The head unit is a F30, info:
BMW 6512 Part no: CI 6 809 243 01 TYPE : EVO HU
Model no: HB B140 EC: 110
100991 10 HW:2.3 SNR:2844397
Version : ECE Data 32/15

The MOST loop has been terminated with a loop terminator, and with the factory amp, there was an echo that was horrible in calls.
I decided to upgrade the amp to an F01 amp (65129248552). However, since the upgrade, I don't have any sound, nor any door chime when it's opened.

The fiber optic connection is good (I don't have the "no warning tones" message). Amplifier has power and turns on (I can see a red light coming from the MOST port on the amp when I power it on solo). I also checked the voltage of PIN 1 - when jumpered with pin 2 it has 12v.

Here is what I think the problem is - the amplifier has old software and is unable to communicate with the head unit.
The head unit, I have been informed (from bimmer retrofit) is coded appropriately, they printed this screenshot of my backedup FDL


I have ESYS 3.27.1 and E-Sys launcher premium, as well as the PSDZdata files v61.5. What I don't know how to do is use this to upgrade the amp ECU.

If someone has more insight into what the issue could be and how to go about solving it, i'm all ears.

On a side note, I did something super cool to solve the over heating problem - the F01 amps come with a fan, for cooling.
I installed a 45 mm fan directly onto the amplifier vent - using anti-vibration mounts. Wired it to a relay switch, using the center console power wire as a primary switch wire (it powers on when you start the car). In this way, the fan is only operational when the car is running, and thus cooling the amplifier!

I didn't take a picture of it, but everything was connected directly to the battery hub - using OEM connections for a slick factory look.

Have you connected the +12 MOST? It is a small connector 4 poles, a wire +12 is enough

[Loliceman]

I haven't done many NBT EVO Retrofits on E series that fitted F series AMP. But a general notice, have you tried to "Store MOST configuration" either in ISTA or actual headunit inside Tool32.

Another tip, just blindly firing from the hip here
Ff everything is connected and kl15 ON - can you remove MOST connector from amplifier and check that INCOMING and OUTGOING light output is active.

Last one:

What is your HU_NBT2 cafd > 300D KOMBI > EINHEITEN_MASTER set to?

In the MOST connector (on the amp) there are 4 small connectors (number 1 to 4) - I jumpered pin1 & 2 together. When jumpered there is 12v on pin1, and 12v on pin2. When not jumpered, there is only 12v on pin2 and 0.0v on pin1.
Are you saying I should run a 12v wire to pin1 or pin2 separately and not jumper the pins?

I have very limited coding experience, as such, I’ve never done ECU coding with those tools, so I don’t know how to answer that question.

This one I can answer. I did remove the MOST connector, and the incoming light was active, and the outgoing light on the AMP was also active.

It is set to kombi_l6 [01]

I hope I answered your questions clearly

I found some more information. My head unit is coded with 677 logic7 Top HiFi option.
Could it be possible that it needs to be coded to option 752 to work with an F10 Top-Hifi amp?

If anyone could help, I would appreciate it.
Thanks in advanced.

SA752 is not F10 Top Hifi but SA752 is Individual high Sound

I think I may have worded it incorrectly, I'll rephrase and you can correct me if i'm wrong.

Currently, my head unit is coded for SA677, i believe that's the option for TopHifi audio.
When I had the original Logic7 amp installed the audio worked - but with an echo. Now that I changed to an F10 amp, I no longer get any sound.

The F10 amp, is meant for SA752 (individual audio system).

Therefore, logic would dictate that coding my head unit to SA752 would fix the no audio issue i'm experiencing...no? Or is my line of thinking flawed?

Thanks for the help.

But I do not understand what your current problem is, either you know coded or you do not know, in the following case, you have to call a qualified person.

Just change a parameter in your head unit, if you do not already know how to do that, give up and pass the hand to someone experienced.

hk_surrounsound to individual sound or something like that.... it's really easy

I'm asking for help. If your unwilling or don't want to help, I understand. I'm asking for help from anyone who knows how to code to share their knowledge so that I too will also know how to code my head unit and solve my issue.

Giving up and passing - no one ever learned anything from giving up. Heck, you wouldn't even know how to code a head unit - because i'm 100% sure you didn't know how to do it the first time. You had to learn too. So why shouldn't I be afforded the same opportunity to learn?

Thanks.
