• Ammonia Slip: Excessive urea injection can result in ammonia slip, where unreacted ammonia is released into the atmosphere.
• Emissions Non-Compliance: Incorrect tuning can cause the vehicle to fail emissions tests.

To mitigate these risks:

• Start with Conservative Adjustments: Make small, incremental adjustments and monitor the system’s response.
• Monitor Emissions Levels: Regularly monitor emissions levels to ensure that the vehicle remains compliant with emissions standards.
• Consult with Experts: If you’re not experienced with SCR tuning, consult with an expert technician who can provide guidance and support.
