My SCG-1 started acting up, as can be seen in this video at 30 seconds in under a very light throttle in 5th:
It just cycles power. In that video is the first time it has done that. I took it out a couple times over the weekend and on one long ride it did it like 3 times while simply cruising down the road. Then sitting in the garage with just the key on, it would show its normal 22.4afr, and once in awhile just show 14.7 for a quick second then go back to 22.4.
So I checked, jiggled, inspected, etc all the wires at the ecu. Everything looks good, no change in the gauge when doing so. Checked all my connections up at the gauge, jiggled, yanked, etc, gauge was steady. The SCG-1 and MTX-D both get power from the ecu power, and ground on the radio frame where the ecu grounds, the only change is the wye at the gauges where each one gets a fuse. The MTX-D is rock solid, so I'm very confused. I was really hoping there WAS a loose wire, so the solution was simple. Oh well, have to see what happens next time I take it out.
First start-up was 05/24/15, so about 4 months ago. The manual states that after 3 months for a turbo car or daily driver, you should recalibrate the sensor.
So tonight, I recalibrated the o2 sensor in free air. So we'll see what happens....
