Ecm took a crap on my mk4 vr6. Looking to swap Ecm's but can't figure out the "secret codes" can anyone please help me out. How and what do I need that doesn't cost 1000 dollars to retrieve these pins?

Hi guys, new to the forum and tuning all together.. I have a mk4 Gti vr6 and had to swap the ecu. Issue I'm sure all of you know is the damn pin codes. How can I retrieve the pin codes off of the original ecu and the used one I bought? Any and all help will be greatly appreciated. Again just getting started with the tuning also. Anything I need just let me know I'll get it.

Please read all the stickies in this forum.

Read all stickies, have all software on laptop and have ross techs cable, communicating with car and reading ecu... now im trying to use ME7_95040, ive got it all the way to the point where it gives me the help lines, now im lost!!! Its been A very long time since ive done cammand prompt and was wondering if anyone can assist me on what to write next or do next.... this is the command line that gets me into help from here im lost.....c:\users\rick1\documents\tuning\me7_95040.exe
 

Did you try adding the arguments to the command line as described in the stickies you supposedly read?

Yes, problem is I'm not sure I'm imputing them correctly, that's what I'm asking for help with. Car is dead in the water. I'm just trying to get it back up and running. If I wasn't in a rush for the car I wouldn't be such a pest. But yes I've been reading the entire forum and it's confusing the hell out of me... it's definitely a good thing cause I sure am learning a lot. I'm very new to the whole thing, and I'm not trying to have people do it for me.
Thanks for the response.

copy/paste the cmd screen (please use mark/copy, not screenshot) of what you are trying to do.

Ok here you go. now im trying to access through usb port, not sure if that makes a difference or not. Location 0 (Port_#0004.Hub_#0001)

What on your PC is using COM port 4?

not sure, sorry, i go under device manager and it gives me this Location 0 (Port_#0004.Hub_#0001)
My ross tech cable is hooked to that usb port.

Sounds like you need to install Rosstech VCP drivers.

Nefmoto communicating with ecm, drivers installed and says cable working properly...

Oh and ecm is in boot mode.

COM4 is not usb port 4.

You need the vcp drivers, as others have already pointed out, and is documented, well, just about everywhere.

like i said, nefmoto works and reads ecu.. dss drivers installed. rosstech drivers also installed. no option for vcp at all. running windows 7 i see no option anywhere for vcp driver. what am i doing wrong or do i need a new windows? ross tech drivers good for xp,vista, 64. any other options for drivers? and like i said been reading this forum a ton just didnt read all 1000 posts.

Read the part about vcp drivers.

http://s4wiki.com/wiki/Tuning#Flashing_utilities

ok figured out the vcp driver for windows 7, box is checked for load vcp. and still not getting in.

Which com port did you assign vcp to?

thank god for you my friend..... finally got vcp to work port 3. figured that out. now its  giving this.. havent had a chance to read up on it yet as its only been about a minute since i reached this point...

LOL at least i thought it was... I give you guys credit!!! This has me second guessing getting into tuning! Its very addicting didnt sleep last night and im back at my shop at 500 in the morning to see if i can get skc codes again...

Here I'll toss you a bone. Daz made this a few years ago before he passed. It's a me7.1/7.5 immo off eeprom. No skc or vin just write in bootmode and reinstall ecu away youll go. Good luck

Marty thank you very much for the reply and bin. says can not read flash do to immobilizer not authenticated..

Download the Ross-Tech VCP drivers and Update the drivers in device manager by pointing to the VCP files you extracted.

Don't forget to go into properties of the device after updating to the VCP drivers and enable the VCP in the advanced settings of the driver tab.

Drivers are all updated and working, i think im really screwing this thing up. lol all just to replace an ecu!!! thanks for the response.

write in bootmode with argdubs eeprom tool not nefmoto

Thanks for the reply, I thought about that on my way home, I'm getting caught up in so many programs and different things that my head isn't straight. I'll let you guys know how I do.
Thanks a lot

I'm in NJ 07882, if you want to stop by my shop I'll can give you a one on one session show you how to bootmode flash the eeprom on your ecu

That would be awesome, I'll take you up on that!!! If you can send me your info and I'll contact you or vise versa.

For future reference, you can use VAG-K+Can Commander to pull the ecu SKC/pin without dealing with bootmode. Takes 5 mins. There are a few good guides out there.
