i was wondering if a wideband o2 sensor can be used for short periods of time for tunning a 2 stroke motor. would it read ok or would the oil foul it out. would the air fuel readings be the same as a 4 stroke? i have a lm-1 kit and thought i might be able to but on my mach z for tunning purposse

 

Yes it can be done. o2 sensor won't last long though 10/20 hours

 

use a good oil like klotz with 20% bean oil or royal purple two cycle
