Resumen

00:00 - Our first question comes from Boris who's asked, can you replace a factory O2 sensor with a wideband? As in, will I need to make changes in the ECU? No unfortunately you can't change a factory narrowband sensor for a wideband.
00:15 In the GM world, the narrowband sensor is the one that they've chosen to stick with for the majority of their applications.
00:23 Wideband O2 sensors are actually used by some manufacturers but again they are rare, mostly on very late model vehicles so you are stuck with those narrowband O2 sensors.
00:33 Problem with the narrowband O2 sensor is as their name implies, they're only able to read over a relatively narrow range of air/fuel ratio, basically at the stoichiometric air/fuel ratio.
00:45 They are pretty good for controlling the air/fuel ratio at stoichiometric and closed loop control conditions but they're absolutely useless to us for tuning under power and enrichment conditions.
00:55 So generally what you'll do here is either add a standalone wideband sensor.
00:58 If you are tuning just your own car you can choose to add a gauge to your car so you can view the air/fuel ratio and then input this into your scanner.
01:08 If you're tuning multiple cars then a portable wideband like the one that I use is the way to go.
