As title, would anyone be able to tell me the exact process for updating the 677 amplifier firmware. I've read that some have said it can be sorted with WinKFP and some say only ISTA P with ICOM. Well I've got all of that, so can anyone help.

Exact details are, I've retrofitted 677 to my E89 and got the amp from an E70 (same part number amp for both models), so all I need to do is upload the E89 firmware onto the amp to overwrite the E70 I appreciate that this is the E9* site and you don't deal with either the E89 or E70, but it's the process that's the important part here, TIA

PS - I have tried searching, but can't find a post where someone actually states the process, a few members have come back with the "upgrade to an aftermarket amp" but I don't want to do that as I want to keep it OEM.

It does work, but due to the positioning of the woofers, subwoofers and the addition of the rear centre speaker in the E89, it requires the correct firmware update.
The problem is that the E70 woofers are mounted in the rear pillars, with the addition of tweeters, and the subs are under the front seats, whereas in the E89 the woofers, no tweeters, are in the front footwells and the subs are behind the seats, so the sound distribution is quite different.

I've coded the 677 to the headunit, as per standard practice, and will attempt the WinKFP tutorial I've found when I get the chance in the next few days. But as I'm not expecting this to achieve what I need I'd like to have the ISTA process to hand so I can try everything in one hit if need be

you're right but this is changed by amp coding, firmware change is not required always if the p/n is fit car body spec - E89
it has in its options the body of the car

Ahh, OK, I see where you're coming from, thanks

This is the post I found regarding using WinKFP...

I've already done steps 1, 2 & 3 (3 being I've default coded CIC), so I'll do step 4 then and see where we go from

the issue in topic linked with another amp, harman kardon, which was manufatured from 2004, long before CIC headunit was introduced
z4 and e70 have different amp and speakers for 677 option - lear,
later these options were separated, 677 stayed as is and 688 was assigned to HK on e9x

OK, so are you saying that write up won't work for me?
If so, how do I code the amp? Not having canbus means that I'm down to the icom for the fibre optic connection, so back to ista?

no, the amp is available thru headunit operating as can/most gw if most loop is operational
simply code it using 677 option

Procedure for updating the logic 7 am through winkfp can be found in
the coding subforum . There is not reason to do it if the amp is playing
though.

Are you already familiar with coding modules a little bit or only theoretically?

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.

With regards
Lado
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.


The above from this thread.

Thank you I had seen that previously, although it is slightly incorrect. Where it states "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." You shouldn't have to if you've performed an SG_Codeiren to the CIC, as this would do all processes itself anyway.
In retrospect it looks like my firmware is already good enough as it's now all working.
I really appreciate your help

Awesome
Found AMPT this morning, had some music playing so pressed the mute button to pause it, performed an SG_Codeiren to the amp, gave it a couple of moments to reset, then pressed the mute to continue playing and WOW!! The difference is staggering, a couple of tweeks to the equalizer and we're all up and running. Going to really enjoy my drive to work shortly.

That's what happens when you start reading far too much, confusing different information that just blinded me to the fact that it could be done that way. I should have known, after all that's how I coded my Combox

Again thanks very much for your help, really appreciate it

Seems to be confusing as to when you need to do this amp firmware update .
When you don't have sound after changing the amp seemed to be the trigger to change it in most cases. The bit about using Inpa to test the amp even if it doesn't to establish if it is working is new to me.

I suppose it's down to age (like a lot of things ) whether you need the update.
Either way everything is now working, and that's what matters.
It was great driving to work, just listening to different types of music to test out the surround sound.
Just got to swap the subwoofers over to the better ones now, which should be here by the weekend.
Again, thanks

Guys, please help me, I know that being asking for different model is not cool, but the topic is the same, so here is my struggle:
I decided to replace my E60 logic7 with more powerful, more modern BMW audio... So here the fiasco began...
First I bought whole audio system from F01, changed the mids and tweeters in my E60 with the F01 ones, but I replaced the subwoofers with ones from "Individual audio"
Then it turns out the F01 amp is not working, so meanwhile it was in repair, I bought an individual M verst amp from e64. So far so good. Then realized that the front right channel doesn't work, before and after coding my car (with CCC) for 752 Individual.
Then bought an amp from E70, which is AMPT70 PL6 TOP-HIFI VERST, thinking that it will sound the same as the individual, as many people said that the hardware is identical between E70 AMPT70 and AMPH1 top hi-fi M verst. Only the latter (individual one) plays with astonishing bass sound.

The bad think is that both the amps are distorting the sound once volume gets loud, but not extremely loud. And I cannot figure out whether subwoofers distorts or mids/tweeters... Tried a lot with equalizer and treble/bass adjustments with no significant success.
My question is this: Is it possible to flash firmware to the E70 amp (AMPT70) for individual amp (AMPH1) so effectively the E70 amp to start sound like individual audio one? Or if not possible, is it possible to read the configurations for individual amp from some config file and manually copy/paste it to the E70 amp config file, achieving the same thing - making the E70 amp play with same settings as the individual amp. (Volume settings, crossover points, equalizer settings, gains... etc etc)

Any help with opinion of how to investigate the distortion of the sound with all amps on high volume will be much appreciated. I am wondering if power cords going to the amp isn't too thin and therefore the amps are lacking enough power...

[DavesZed]

From my recent experience.....
The amp I fitted was a cross referenced part with the E70, so was fully compatible with the E89. So in the end all I needed to do was to default code AMPT through NCSExpert. Prior to that, although it was working, it was very "bassy", once coded it was spot-on.
The reason for it being "bassy" was because of the different programed environment between the E70 and E89, but this was changeable because it had the correct firmware. Now the E70 amp is not cross referenced with your E60, so won't have that environment preprogrammed into it, and I'd doubt you'd be able to do that either. What you need is the amp from an E9* (3 series) or E8* (1 series) as these are compatible.
Hope that makes sense.

[tzvetandacov]

Let's say that tha amp I have from E70 is also used in e90 (just as example), for me to code it for e90 and test whether it sounds ok or at least better then now (now being coded let's say for E70) do I need the amp to be plugged in E70 or e90 car to be coded or it will be visible and therefore possible to code it in my E60 (again, for different model, I do know that e60 is not an option in this amp)?

[tzvetandacov]

Here: www.e90post.com/forums/showthread.php?t=802793
I see that settings like VOLUME_ADJ_1 and many more settings like it has value like "e93_hifi" which to me looks like some config file with name e93_hifi.
Do I have access to those files? My point is to manually change some settings for equalizer, cross over points until I get decent sound. Or this files are inside the amp and cannot be changed/overriden?

It would be default coded to the car it is in. But, this isn't going to work as it wont have the settings for an E60.
Example - The reason my E70 amp didn't sound right is because of the way that the E70 (as that is the vehicle it came from) has it's speakers positioned and set for that environment. Things like the subwoofers are under the driver and front passenger seats, whereas on my E89 they are positioned on the bulkhead directly behind the driver and passenger seats ( 5 seater in the E70 vs 2 seater in the E89), also the woofers are mounted on the C pillars in the E70, but in the driver and passenger footwells in the E89. So these positions and the general arrangement of the cars are completely different. So this goes to stand that there are going to be similar differences between the E70, E90 and E60 that will contribute to this affect.

The coding is done by, basically, taking the spec of the car from the CAS module and then telling the module, in this case AMPT, of what vehicle it is in. So in your case you can only tell it it's now in an E60, but it won't have the firmware for the E60 environment, so will probably fail to code.

[ctuna]

In the early years the e60 , e50 had a completely different logic 7 system in which the actual amp channels where distributed between the Head Units and the Amplifier . This period lapped over between the start of the e90 series.

if you want high power sound you need to get all individual speakers and repair individual amplifier
you may also stick with e70 amp but with f01 speakers as well
