My DIS/INPA/SSS/CARSOFT/NAVCODER Interface.

[TurboBimmer]

here is my simplified real ign detection mod.

you don't have to use the 4.7k at the collector as in first schematic, the ft232 has a 200k internal pull-up .

also the base resistor has to be minimum 10k, i had an 120k one, the higher the better , lowers base current.


here are the simulation and pictures.

djcristi, is this a FT232BM you're using?
If yes, I think you installed the transistor backward. On yours, the emitter is going to pin 20 which is DSR and the collector is going to ground. It should be the inverse.
I would be carefull with the use of a very high value resistor at the base. If there is not enough current going into the transistor base, it may not be switched ON 100%. We are using the transistor as a switch and it should work in saturation.

Hi. ALL THAT HAVE THE RL-CHIP!!

It´s crucial that you check out that picture that I posted earlier.
Do the soldering exactly as I did, and remember.
DO NOT INVERT THE RL-Chips DI# DSR# with the software, if they are inverted the cable wont work. So if you use the REAL ignition detection, flash the chip again without the taps in DI# DSR#

I can´t include the pics here for some reason, so clik the links..

After you have done these things, you should have a working cable.

The BC547 should work if you don´t have a 546.

Hi poteroa,
while looking at the mods for the cable, I found a little mistake in one of your pictures that may induce some people in error.
In the second one, it shows the TO-92 with the labelling EBC. Since the transistor in the picture has its flat side down, it should read CBE.

Hi.

I took the the picture from manufacturers page that has the info of the transistor. Check again, no mistake, the pinout is quite right. the C-leg is suppose to go to RL_chip pin 9, and yes the transistor in the picture is facing down.

Hi guys i found some old video tutorials that i made sometime ago, about software configuration (ediabas,inpa and dis) but they are in spanish language.

Anyways maybe you will find them usefull

here we go

Advice: i remember there's one step missing in ediabas and something else that i can't remember but DIS configuration is ok lol

1º Set environment variables

2º Installation of bmw-tools (ediabas)

3º Installation and configuration of the USB port

4º Installation and configuration of INPA

5º EasyDIS and VM Ware installation

6º DIS v44 installation

7º Final configuration of DIS

E36 requires an ADS interface to read all modules.

Hi,

Do I have to modify something in the 20PIN/OBD2 adaptor to make ignition detection work ?
DIS says the 15 pin is OFF when I try to scan the car, it does not detect battery... any idea ?

Thank you

[Orphee]

[EmilC]

i have a question is this cable mod as good as a gt1 cable or whats the differences between this two cables. and are there any update on the d-can cable, is it possible to mod the vag cable to handle d-can?

[notease]

Could someone make me a modified version of this one ?
I cannot manage to this so small soldering
of course i pay all costs ?

[silyb0y]

Hi Locum! Id like to thank you for sharing your knowledge with us. Thanks to you I have a perfect working OBD adapter

Heres something interesting...

Id would like to update the flash eprom of my radio module (BM54). Ive have read (xoutpost.com) that it would be possible without desoldering the flash eprom.

Therefor I would need an USB <-> Serial (TTL) adapter. Question is... what kind of signal are K and L line? Are they TTL signals? Can I (ab)use my VAGCom adapter as an USB <-> Serial adapter (must be TTL)?

Thanks

[locum]

You need to see:

FT232 Datasheet
Vagcom 409.1 Pinout

also you can use GOOGLE

Hello,

I have bought this cable with FT232RL chip: http://www.obd2-shop.eu/diagnoseinte...rat-p-151.html .

Which looks exactly the same as poteroa cable.

Just 2 quick questions:

Will i be able to program car key memory with only the software mod (with SSS/progman)?

If this is true i won't bother the soldering part .

I have modified poteroa picture to this one:

Is this correct??



Thnks

Hi all,

I went to Radio Shack and try to find the transistor BC546 but I couldn't find any. I bought a Radio Shack brand one that said 2N3904. Would this work in place of the BC546? Here's the rating on the package:

hfe(min): 100
Vcbo: 60V
Vceo: 40V
Vebo: 6V
Ic: 200mA
Ft: 300MHz
Dissipation: 350mW
It's a TO-92 case

Hi, if you don't do the hardware you can't do car key memory with DIS... but you can do car key memory with NCS-Expert just soldering obd2 pin 7 and 8 and doing the software trick

Basically any NPN transistor will work.

My modified VAG-COM KKL USB cable with Radio Shock 2N3904 is fully functional. You will have no problem using it. Cheap and readily available.

Thanks guys. I will try it out.

[AdrianEvans]

PM me if you want to buy one of these modified cables. There is a new listing on ebay for BMW kkl cables though...

This is NOT ebay

[wildcat293]

So this should work with carsoft 6.5?

INPA is working great but I can't get carsoft to connect to any of the modules. Any tips?

Thinking about adding some ceramic caps to the data lines...

[locum]

It won't work with Carsoft 6.5 but do work with Carsoft 6.1.4

[wildcat293]

It won't work with Carsoft 6.5 but do work with Carsoft 6.1.4

Good to know! will stop trying to get 6.5 working =)

moving on to SSS and all the other goodies

Sorry if you take offence. Notease above asked and since I can not PM directly I made a post. Just trying to help a brother out.

You have 2 options to modify CAR KEY MEMORY:
1. With DIS you need ignition detect (Easy use)
2. With NCS you don't need it (Hard level software)

BTW i didn't see your picture

Hello everyone.

I have FT232BL chip. Should I solder 17,18 and 20 pins of the FTDI chip?

Thanks in advance

[zekan23]

1) First of all I should solder OBD2 pins 7 and 8, which are the K lines, otherwise I will not be able to access to all modules from the car.



2) After that I should do real ignition and battery detection as described djcristi at post nr. 21 using this scheme.

I need

1 resistance of 10 kohm or higher (djcristi used 120 kohm)
1 transistor BC546 or equivalent



Should I solder pins 17 and 18 of chip? Next photo is unclear, but on previous scheme they are soldered as I understood.





3) Downloading the latest driver v2.08.14 (release date 2011-04-12) from FTDI website and installing them

http://www.ftdichip.com/Drivers/CDM/CDM20814_Setup.exe

in My Computer settings set COM1 port and 1 ms of latency

4) Using Mprog 3.5 (was replaced by FT_Prog_v1.12)

MProg 3.5 http://www.ftdichip.com/Support/Utilities/MProg3.5.zip
or
FT_Prog 1.12 http://www.ftdichip.com/Support/Util...Prog_v1.12.zip

should flash the chip with the following



is it correct ???????
