I am not currently running an ecu. Do I need any control modules for the signal between the sensor and the gauge or can I just feed the correct signal to the gauge? sorry for any ignorance on my behalf this is all pretty new to me and good old carbis are pretty simple 1970 technology!!cheers Link to comment Share on other sites More sharing options...

Is it really that bad using a narrowband sensor considering at the moment I am tuning the carbies with a vacuum gauge?In an case once I have finished my EFI conversion I plan on installing a wide band sensor. What are the best brands for sensors and controllers? Innovate, Autometer, Speco, AEM and there is also an aussie website selling sensors and control modules wbo2 or something? Any brands to steer clear of? Link to comment Share on other sites More sharing options...

The black and grey are the variable resistor and it changes resistance as the A/F increase/decrease. This can be do found on the Bosch website if you download the o2 sensor catalog. It also explains how to test them too. Link to comment Share on other sites More sharing options...
