Thanks guys for helping me out. So, the way I am understanding it is the lambda really controls the cis fuel distributor starting with my '80 engine and this distributor is recalibrated from the earlier type to only be used with the Lambda. I must not be experiencing the potential of this engine that I've invested in, and now, thanks, I know I want to put a cherry on top and do the lambda.

May I benefit from using a 81-83 setup on my car? I have an '80 engine and I have read that they incorporated a few different components on the later system. I would imagine these would be an upgrade if I can install them on my engine, or were they to satisfy emissions requirements?

I do have the '80 Frequency valve within the fuel loop, the black throttle switch which comes out of the throttle shaft, and I have a short part of the harness which connects the switch, fv, and I think lambda 8 pin connector for the main Lambda harness, which I am missing, down to the control unit.
The Wur I have is the vacuum type. Is this correct for '80? Is there a reference for part numbers that anyone knows of so I can match this guy up?
Were these warmed sensors already, or is this a doable upgrade when I install?
Thanks so much! A few of these questions answered and I'm off to the used parts forum to find a unit and main Lambda harness.

Thanks Longhorn C for noticing my Fuchs… I feel very fortunate to have found them, finally! I am really loving the car. A few details here and there and I'm ready to start fixing up the next one .
