I plan on installing a wide band O2 sensor with a meter that will give me an air/fuel ratio. Can I just use this O2 meter instead of the stock O2 with my CIS-E fuel injection system? It has an imput for that per the instructions and one for data logging.

Also if someone can point me to where I can find some info on making adjustments to the system other then the ones listed in the repair manuals. I have at least one shop manual and two others covering the various CIS systems and their workings but it's all still "Greek" to me.

The car is a 1988 16V Scriocco.
