Wideband O2 Setup

I want to replace the factory Narrow Band sensors with Wide Band. What do I need for the ecm to handle it? It's a 2021 Roadglide Special Stage 3, SE headpipe; Khrome Werks slip-ons, tuned with PV-3.

I see dynojet.com has a kit but is not available in dual channel for 2021, only single channel with one O2 sensor. Seems like only half of the solution to me.

Any thoughts welcome!

I don't know where the o2 sensors are located on a Screamin' Eagle headpipe (never seen) but you will need the larger 18mm bungs located close to the exhaust ports to accomodate wide band sensors. I do know that Thunder Max is developing a new ECM for the 2021 & newer models though and they always use wide band sensors for their increased flexibility. I don't believe you can accomplish what you wish with the stock ECM regardless.

Doesn't matter who's version of a kit you would buy, they are simply incapable of tuning an engine! To tune an engine it requires a lot more information than an O2 sensor can provide to the ECM. Things like Spark timing, cam adjustments, EGR, MAP adjustments and proper fuel mixture for the components your using all need adjusting and changing an O2 sensor simply does none of this.
