You must follow specific technical steps before you unbolt the old hardware.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"software-calibration\">Software Calibration<\/h3>\n\n\n\n<p>Modern Honda vehicles require the latest ECU firmware. Software updates often improve the logic for DPF regeneration. The manufacturer frequently tweaks the temperature thresholds and timing. Ensure your vehicle runs the most recent software version to protect your new investment.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"lubrication-requirements\">Lubrication Requirements<\/h3>\n\n\n\n<p>Diesel engines with DPF systems require specific engine oil. You must use ACEA C2 or C3 compliant oil. These \u201cLow SAPS\u201d oils contain low levels of Sulfated Ash, Phosphorus, and Sulfur. Standard oils produce ash that the DPF cannot burn off. This ash permanently blocks the filter.
