Well, Ive finally managed to install my wideband lambda sensor in my valver.
Its the Zeitronix ZT-2 with extra display.

At first I didnt know where to put the display as it is a pretty big casing, but when I took out the display I saw that I could just make it fit instead of the temperature display in the clockunit.
It was a pretty painstaking job, but Im very pleased with the result.
Now all I have to do is to get the mapping right, so I can finally drive my valver to its full potential again.
