Thank you for your order. It is true, all of our tunes have been designed to run with the O2 sensors disabled. Our tunes have the O2 sensors disabled specifically so we can control fuelling of idle and low throttle openings. Air cooled twins do run quite hot in the Summer whilst in stop/start traffic, so a rich idle can help the engine stay a little cooler and in the Winter, it helps with cold starting/running. Our experience has shown the twins run better this way. We sell an O2 removal kit HERE.
Your problems may stem from the O2 sensors reporting back to the ECM and trying to change the fuelling of the tune. Once you have removed the O2 sensors, please re-load your new tune and carry out the “Reset Adaption” routine from a cold engine
