Issue: On some Polaris and Can-Am models, installing a different primary clutch like the P-Drive can trigger a misfire fault code. This happens because the vehicle's ECU is calibrated to the vibration frequency of the original clutch. The new clutch, although functioning normally, might have a different vibration signature that exceeds the ECU's knock threshold limits, leading to these fault codes.
Solution: If these codes appear after changing the primary clutch, you might need a tune update. For modified vehicles, get the latest tune files from tuners like Whalen Speed, EVO, AA, DynoJet, etc., which account for this change. For stock vehicles, have your dealer update the ECU with the latest software. Note: These codes could also indicate an actual misfire due to issues like a bad oxygen sensor or faulty spark plugs.
