So reading about the wideband o2's and thinking about getting one to help with better tuning. But I have a couple questions I cant really find the answer to.
If I want to wire it up to where it connects to that egr pintle position pin on my 7427, and then it will display on my datalog screen, do I still need a stand alone wideband controller?
Do I connect the sensor output wire from the wideband directly to the pcm, or do I have to buy one of those expensive WB contollers?
