Burn out issues

C12 or VP blue. All leaded. The sensor is a year old. I use it to get in the ballpark. Then tune for mph. I really like the gauge when the car does something funky. Say it has a slight miss at higher rpm. Look at the gauge and its lean. You know it is fuel/air related. Same issue but it’s fat. Probably ignition. Could be flooding the bowls, but that is pretty obvious. That and I’m working on the lean spike at the hit. I have the carb so far out of its comfort zone, that I can’t really slow the sec air valve down enough. You can break the small spring that controls it if you tighten it too much. It just needs a sec enrichment system, like the AFB or a Holley. I have an old AEM gauge that worked for years without killing the sensor. Did it lose accuracy? Probably, the number to me isn’t as important as long as it stays pretty much the same throughout the day.
