Oxygen (Lambda) sensor removed and new one soon in place

To be able to use "close loop"and optimize the fuel injected into the engine, the Megaquirt FI system needs a wideband oxygen sensor to be used to give feedback to the MS ECU about the amount of CO in the exhaust gas.

I bought a sensor from Innovate which also has a gauge showing either the Lambda or the AFR (air/fuel ratio)-value which I'm planning to mount in the center ventilation output on the car.

The gauge has 2 analog outputs where the second output can simulate a narrowband sensor like the one I removed, I will try to connect it to the original Lambda sensor control and see if it works before I do anything else. Could be fun to see how well the K-Jet system perfoms.

Since my car alredy had a narrowband oxygen sensor controlling a "frequency-valve" which helped the WUR to adjust the control pressure in the K-Jet fuel distributer,  I can put the new sensor where the old one where mounted.

Rich mixture = High CO = Low Oxygen
Weak mixture = Low CO = High Oxygen

This is how the old one looks likes beside the new one...
