EFI Software - how to find it?

[baq911]

Hello,

I have a 3.3TT that is running too rich at the moment (It shoots black smoke when I get on the turbo's and smells like fuel). It runs rough and jerky before the turbo's wind up. I believe it needs to have the software re-configured / flashed. In order to do that I need the old software. I bought the car this way with this set-up. How can I find the old software (Which I'm told is a dos based system)?
My AFR reads 10.5 which is rich according to the guide below. I took pics of my EFI and AFR units. Any help would be GREATLY appreciated. Thanks in advance.












The three regions of operation are shown at right. A normal operating value (of 14.7 in this case) is shown as three digits. A rich condition is shown as 10. followed by an equals or less than symbol (=<). A lean condition is shown as 25. followed by a greater than or equals symbol (>=). Note: display is operating in dot mode.


Here's one of the car:

Did you try the manufacturer?
