O2 Sensor used with Innovate SCG-1 AFR/Boost gauge?

BKL · Sep 28th 2019

My Innovate SCG-1 AFR/Boost gauge sometimes doesn't display the AFR after starting the engine. Other times, it loses the AFR display it had been showing. I emailed Innovate Motorsports that my guess is there is a short either in the O2 sensor pigtail or in the cable that connects the pigtail to the actual gauge.

Does anybody know if the SCG-1 uses the Bosch 4.2 or 4.9 O2 sensor?

Mine as a new one will occasionally boot up and stay on HTR. It takes a restart to resolve it.

Use the Innovate 3888 Bosch LSU 4.9 O2 sensor wide band. I have changed mine and it works fine. Make sure you follow calibration guidelines. I got the best price from Eric's Performance Parts,

Before you buy a new sensor, recommend you take yours out and clean it, reinstall and calibrate. I am betting it will work. Soaking overnight in gasoline is recommended for cleaning.
