The SCG-1 has it all, but does it…
I have had my SCG-1 for about 10 months. For 8 months it worked flawless and worked as described. About a month ago I had started having issues with my wideband. It would jump all around on the AFRs and then it would finally just stick to full lean or full rich. Mostly would stick to full lean. Sometimes it would not even heat up and read the AFRs for a while. I would calibrate the sensor properly and it would last for a half a day, day or sometimes two days with no issues. Out of nowhere it would start doing the exact same thing again. Recalibrate and start back over again. It was maddening. I ordered a new innovate WB sensor, calibrated it and it was doing the exact same thing as the original sensor. Having chased my tail before on having a bad new part, I contacted Amazon and they sent me another brand new WB sensor to replace the already new sensor that I had just received. Recalibrated the second new sensor and it was still doing the same thing. That is where I was at with that problem.
I had another ongoing issue that was very intermittent and I would overlook during issues with my wideband. The Innovate MAP sensor would just blink out here and there for just a second or two. When I made it to WB sensor #3 the MAP reading would stay on 29.8hg and blip to 0psi nonstop. SCG-1 is just occupying time and space in my dash at this point and just useless to me in every way.
I looked online to see if anyone else has had the same issues and ways to test and diagnose the issues…
