Hi all,

Done a lot of searching and cant seem to find the definitive answer.

But recently replaced my door speakers and added tweeters along with new rear deck speakers.
Looking to now wire in a sub and was planning on coding the Pro HU from Base to HiFi.

Was looking in NCSExpert yesterday to try find the correct code to change. Having a bit of trouble locating the correct coding in the correct ECU some threads point to RAD2 others CIC?

I've also read that coding is completely impossible on early build cars. Mines Mar-2006.

Anyone done this on a Pre-LCI?

[borinous]

just check build sheet and i have S663A with S694A (provision for CD Changer) and build date was Jan 2006.

Which module to code depends if you have idrive (ccc/cic) or just the standard radio (rad2). Of the top of my head I can't remember the exact steps but I have coded the RAD2 in my 2008 pre-lci

When you view the list of modules in NCSExpert you will see Rad2 or CIC but I don't think you would see both.

[borinous]

had another look this evening and I definitely have RAD2. just not sure which option to change?

[Sbm007]

Yeah you will have RAD2, if I remember correctly you will need to add option $676 to your VO (google how to modify VO using NCSExpert), you want to add this both CAS and your FRM module.

Then code a blank MAN file to your RAD2 module to reset it to default settings.

You might also need to trick your HU into thinking it's a newer build date, adding #0909 to your VO should work (again make sure you code CAS and NFRM).

There's tons of info on this on the forums.

Have you had a CIC retrofitted? Or do you have a professional radio?

TBH, with the questions you are asking, I think you should stay away from coding.... as you're likely to do damage!


If you have a professional radio, then you are not able to code it to HiFi using nscexpert - you need ICOM!

thanks mate I'll have another look. I'm starting to think I might be starting to swim out past my depth. thought it would be easier than this. and probally is on the newer headunits.

no I have professional headunit I've coded before with success but that was only switching on or off different options.

you are probally right I might just leave well alone and buy a jl clean sweep or simular.

Not true. Only the newest LCI Professional HU's were installed on the fibre optical network (MOST bus) and yes they require an ICOM to code. Pre-LCI are on the CAN bus and can be coded very easily using the OBD port. It's almost impossible to do damage to your car as screw ups can easily be reversed by coding a blank MAN file to all modules.

I say go ahead with it. If you need more help just ask.

Older head units will work too. I coded a Pre-LCI car before although the owner did have a newer HU fitted in his car but it's worth checking. Coding a new VO option is almost as easy as switching a value to AKTIV. Give it a shot and save yourself some money. The HiFI signal will sound much better when going through the amp!

thanks mate, I'll do some reading up on adding VO

[makkan00]

If there is no amp in the car then its useless to code the HU to hi-fi.

And those who solicit to code the car with blank MAN files are bit clueless. It is NOT a good idea to code a module with blank file as that is when you start getting issues (without knowing). There is a proper way of coding the cars.

[bishbosh]

I was also about to mention the blank .man file coding but Sam beat me to it!

I won't go into too much detail as here is not the place and it's already been covered, but in a nutshell in NCSExpert you add any required $ options to the VO. Then you code the car by running SG_CODEIREN job on the relevant modules. No need to touch any .man files.

plan is to add an amp so that's the theory behind recoding to hifi. to get a better input for the amp.

Thanks for the info

You only code it once you get the amp.
If you are not sure re: coding then use LOC to start with.
If at later stage you think that it is highly equilized (which some people prefer here), then you seek other options.

sounds like the easier option. shouldn't need a LOC as I've got an amp that accepts high level inputs.

[Sbm007]

Well there you go, my point still stands though (maybe not through blank MAN files) but you can easily reverse screw ups. When I was looking into coding and how it all works, I never came across anyone who managed to permanently and irrevocably damage their car at a software level.

Although coding to HiFi is indeed pointless if you have no amp installed (I made the assumption you have an amp).

[borinous]

thanks for all your help and pointers guys.

[borinous]

couldnt check the coding as my laptop was dead (currently on charge) but looking in the Radio hidden menus i have this......



as
DSP - 0 = no DSP installed
and
DSP - 1 = DSP installed

its making me thinking maybe its already coded to Hifi?

[bishbosh]

That just means whether or not a DSP is fitted to the car. Mine says DSP 0 and I've coded mine to HIFI.

[borinous]

but wouldnt it have said DSP 1 when its set to Base. As Base has the DSP and Hifi Doesnt?

[bishbosh]

I think the DSP in the display doesn't mean the built in EQ curve of the radio, it means if you have the Logic7 DSP/amp fitted - an external DSP unit.
