In my experience, if you have a gen2 euro3 bike 2014-2016 then unplugging the o2 sensors (with a couple of o2 eliminator plugs to avoid a fault code) works great as the bike defaults to a good base map and there’s far less need for a remap. Euro4 bikes, 2017 on, respond differently to faulty or absent o2 sensors because the ecu appears to keep excessively richening then leaning out the mixture to kick the sensors into life. Anyway, you can’t just unplug the sensors with the euro4 bikes - they need a remap to make any improvement.
