Hi All

I want to (re)start my project URS4. the story begins 2 years ago....

History:

2 years ago I bought a genboard 3.6 and a 55 pin motronic plug. The idea was to make a harnass to plug into the original 55 pin bosch plug - which I eventually did 6 months ago. It would not start, and I did not have time at that stage to solve the problem. I have some time now, but while I have mapped a car before using the 55pin motronic version, I have no idea how to set this one up. The car does start and run with a friend's 55 pin unit running 1.1.81, so I thought to upgrade from 1.1.27 to 1.1.81 and load his config - if I can figure out how to do that. Maybe there is a better firmware for the Audi urs4?

Problem no 1:

I downloaded 1.1.81 using the web tool, but when I try to upload to the vems I get an error message saying either the car is running or there is no comms with the ecu. Thing is, I can connect and edit values on the ecu, so I don't understand what to do?

Problem 2:

Is saving the config from his unit to PC as easy as "File-Save config"
Is loading it to mine "Tools-Firmware-Config upload"

Thanx for the help!

I updated my Vemstune to the newest July 2012 version and now the firmware update works fine. I updated to 1.1.81 and loaded (I think) the saved config from the other unit. What worries me though is that I get a error message that says I must press the config validate button because there are errors, but I don't find the config validate button...

I attach a log of me trying to start - I see I dont get and rpm signal. I rechecked the wiring from the vems to the 55 pin connector and it seems fine. Maybe I am using the wrong pinout - that I will also attach.

Any thoughts?

oops... how do I post an excel file and a log file?

When connected to an ECU, or offline with a config/vemslog opened up, you find the "Validate config" buttonto the  right of the "LOG" button under the menu bar.

My tip to you, try the latest 1.2.x instead. It works just fine and is easier for troubleshooting. Make sure to use the latest "nightly" VemsTune, see www.vems.hu/vt

To share vemslog and triggerlog files, use the Help menu in VemsTune and the built-in "Error reporting" which requires an internet connection. It creates an online page for your query, the link you are given to this is meant for sharing with the forum and whoever you want.

1.2.2 I think. There is special tweaks for Audi triggering.
Or 1.1.95 (not 96).

I used the error reporting tool (hopefully correctly). Here is the url (I hthink)

http://vems.hu/vemstune/bugreports/reports.php?cmd=view&key=MDAnpV

When uploading the config like this:

http://www.vems.hu/wiki/index.php?page=VemsTune%2FQuickStartAudi

do I only select the 2 top ones: "Basic config" and " Basic tables", or must I select some other options as well?
