Hello everyone,

I recently got a hp tuners pro and have dived into tunning and logging. But I am un able to get my afr gauge reading on my logging. I connected the white wire to input 1 and black (ground to input 5). It only reads 10.38 and jumps back and forth quickly in 10.3X. It never goes anywhere else. Will reading different acts on the gauge it self. I know the gauge itself is accurate from comparing it to a different gauge in the past. The power and ground for the gauge are currently coming from the cig lighter in the cubby. I removed the lighter itself. I went into the scanning program itself added a new channel, selected input 1 and the AEM afr 30-4110. And deleted and added it again with no change. I also tried a different ground. A wire off the passenger side top front fender bolt from the engine bay. Same result, I am stumped and tip or ideas would be appreciated.
