Hello John, Thank you for sharing your feedback and your practical approach. You are completely right that factory passwords and deep-level programming are heavily restricted outside of official dealer networks, and independent techs often have to rely on workaround solutions or external support when dealing with locked parameters. Your point about using reliable compatible hardware and proper diagnostics is spot on. In daily field maintenance—especially when handling recurring issues like governor calibrations (such as Group 70) or specific error codes on older and mid-generation machines—having solid diagnostics and checking hydraulic pressures first remains the best way to avoid unnecessary parts replacement. Thanks again for sharing your perspective, and I'll definitely check out your tutorial videos on diagnostic tools access! Best regards,
