When I got my ride tuned right I learned to watch the wideband and its pattern.

From time to time if I get junk in a carb it shows it before I feel it.

Had one spray run go wrong and the first thing to let me know was the wideband, aborted without any issues. If I did the full run Id of had alot of issues.

So I use it for a warning tool.....

I went 3 years on one of my N/A motors without ever putting a timing light on it......a friend sent me one, hooked it up....dead on 34 locked out, didnt even loosen the dist....good or lucky????

Would you throw your timing light away???
