Should I still get a separate wideband?

My Focus RS uses Bosch LSU 4.9 wideband sensors to measure oxygen content. These sensors will be fed into my Syvecs ECU that I'll be using for road tuning.

In this case I wouldn't really need another/separate wideband gauge correct? The Syvecs can display lambda and other telemetry to my phone via bluetooth so I'll be able to keep an eye on it. Just trying to avoid adding any unnecessary electronics and parts if I can help it.

Probably a silly question but figured that I would ask.

Thanks.

If you're only planning to tune that one car, then you don't need a separate wideband controller.
