Thank you guys. We have progress.
Cole advised me to call INNOVATE TECH support. I did that 15 minutes ago.
The problem was very simple. I had a Terminator plug in the XD-16 out port.
It is not supposed to be there...
Now the Error indication has gone, so I took it for a spin. Well, it isn't all done yet. It indicates AFRs to be around 4,7-5.0. Once it has cooled down. I'll try to calibrate the thing again in free air. The precious calibration might be worthless with the term. åplug in the XD-16 output.
If this turns out good. There'll be beer at my house tonight -see ya
I'll report the results -of the calibration...
