6 Speed Swap & Cruise Control

[Airflite40]

I am finally finished with my 02X GJW swap into my 02 Avant. The last hurdle is getting cruise control to work in 6th.
Does anyone has any ideas on how to get this to work? I've done tons of searching and currently trying to read through the 2.7T swap thread.

The DrJonez method of recoding the ECU doesn't work for me, I tried to change coding to 16711 and VCDS tells me the coding is incorrect.

Any ideas would be greatly appreciated!

You might have to flash a 6 speed bin to the ecu, that's how it works with the 1.8t at least.

[Airflite40]

That's another option I've seen mentioned before. I'm currently trying to get versed in NefMoto to be able to do that if needed.

I do know that the 02 ECU's are different vs 03-05, will a 6 speed bin from an 03-05 work on an 02 ECU? or does the ECU year not matter?

no, the bootloaders are different, you'll brick the ECU if you do that. You'll need an AF/AK/BC ECU to flash a 03-05 file.

I have recoded several B6 1.8T ECUs from Auto to manual trans and vice versa. If the ECU could not be recoded for Manual trans, requiring a MT bin, there is no reason to include that function in the coding number. The AMB bin file is not specific to auto trans or manual trans. The same ECU part number is used with both transmissions.

OP, try logging into the ECU with Login II before trying to recode the ECU. Use login value "32767", then recode ECU 0016711. Next turn off ignition for 15 seconds. VCDS will not show the new coding value until the ignition key is turned on again after 15 seconds. Also, depending on the software version, the coding number may require one or two leading zeroes. Without the leading zero/s, the coding value won't be correct. Note the two "empty characters" 00 leading zeros shown in the coding chart. If you did not include the leading zeros before, try doing that before using the login step.

There is no such thing as a manual trans 5/6 speed ECU bin file/ECU version. Both auto 5 speed and manual transmissions use the same ECU part number.

I've also read that you can't put an 03-05 ECU into an 02, the maps are different and will not work (considering immobilizer is removed)

[Airflite40]

In another thread Clint mentioned that he thinks it's partly controlled by the CCM, so I might try swapping in my 05 CCM and seeing if that works.

[Scotty@Advanced]

Got everything wired up proper?

The cruise control function is incorporated entirely within the ECU. There is no separate CCM.

[Airflite40]

By CCM I meant central convenience module

Scotty- thanks for the fluid for the trans and rear diff. Shifts perfect! Got everything wired up. Reverse lights work and my speedo worked without making any wiring changes. I suspect this is because I have an S4 cluster

You don't need any other files, what you need is just log nvquot_w from the ECU in each gear and set the boundaries correctly.

I have also heard the term "Gangi "
There is a file in the ECU that expects certain gear ratios. http://nefariousmotorsports.com/foru...p?topic=4979.0

Still reading up on this.... Something to search.

[Airflite40]

Thanks Kevin!! That's a great start.

diagnosticator- I don't have the option to login, I have:
Coding II - 11
Coding - 07
Security Access - 16
I tried security access but that didn't work.

Enter the value 32767 in Coding II, the click on the "Do It" button, then recode the ECU using 0016711, then turn the key off for 15 seconds.

I don't know what Clint is referring to, but the CCM has nothing to do with either recoding the ECU or the ECU cruise control function.

[diagnosticator]

I don't believe this is correct. If the immo is cloned on the ECU, or defeated, there is nothing to prevent an '03> 518 AF/AK/BC ECU from working in an '02. The different maps used in an '02 ECU, < AF, are irrelevant if an '03> ECU is installed.

So was this a 2.7 swap or just the 6 speed swap, your first post confused me a little, if the first diagnosticator is correct the cruise control function is entirely in the ecu, if it's the latter, the steering wheel electronics plays a part in the cruise control, it's what the cc stalk is hooked to and what sends the cruise control signals through the canbus to the ecu. If you've changed the coding there maybe a chance you have to re-enable cruise control through vcds.

[Airflite40]

Just swapped the 02X trans. I was referring to the 2.7T swap since it appeared that getting the cruise control to work was also a hurdle for you guys but I realize now that's an entirely different issue.

[Airflite40]

I just tried entering 32767 in coding II, and this is what I got:
"Login Code Not Accepted by Controller

You will have to turn the ignition OFF
for a while before trying again.

Error 31: Request out of range"

That's the same error I get when I try to change the coding to 0016711. Interesting info regarding ECU's. I'll try to find a later ECU in that case. Is the immo defeat specific to the ECU or cluster? I can research more about that.

On another front, I was able to connect with NefMoto and read the ECU, but not read the flash. I'm going to buy the recommended cable for NefMoto instead of trying to use my VCDS cable.

[blitz2190]

You can use the vcds cable but must switch it to dumb mode first under the vcds software

[Airflite40]

Yup did that, that's how I was able to get it to connect. I wouldn't read the flash data, I tried both 400 and 800 memory layouts and it gave me an error for both and failed to read. I will keep reading on NefMoto and try again once I get the better blue cable.

Thank you everyone so far for the help. I'll keep trying!

This sounds about right. Come up north again (and buy more stuff! ;) ) and we can probably make those adjustments to your file. As already stated, just use your VCDS cable in dumb mode...

I have had a lot of problems getting Nefmoto to work via OBDII. (and most other ECU utilities too,) Instead, I built a bench harness for the ECU and use boot mode to read and flash the ECU, works perfect every time. I am looking for the cruise control activation code value to use with basic settings, you can run that and see if it restores the cruise function.

[Airflite40]

Thank you! So just to be entirely clear, my cruise works, just not in 6th. So frustrating that I can't just change the soft coding for the ECU.

[Airflite40]

I was able to find an original ECU file, bin file, and xdf file for an 02 ECU so I will try to play around with those while I wait for my cable to come in. Stay tuned!

[diagnosticator]

Thank you! So just to be entirely clear, my cruise works, just not in 6th. So frustrating that I can't just change the soft coding for the ECU.

If it does not work only in 6th gear, then I think something else is wrong. For example, maybe the clutch switch or the brake switch is kicking the cruise out in 6th gear.

Have you tried using no leading zeros in the coding number entered? How about only one leading zero?

[Airflite40]

Yeah tried all sorts of combos like no zeros, one zero, both zeros. My buddy who has an 02 and did the same swap reports the same thing. Cruise works, but not in 6th. From my previous research it seems like it has to do with the ECU not recognizing 6th gear.

From reading over on nefmoto, some guys who put in a TDI 6th gear have similar issues, as the gear ratio is different than what the ECU expects when activating cruise.
