Abstract: An anti-lag controlled ignition system includes an engine system including a turbocharger and an exhaust manifold fluidly coupled to the turbocharger. An electronic control unit (ECU) is communicatively coupled with the engine system and is configured to receive engine data from the engine system. A virtual optimization system is communicatively coupled with the ECU, and the virtual optimization system is configured to generate calibration tables in response to the engine data from the ECU. The ECU is configured to receive the generated calibration tables and is configured to reduce turbocharger lag via enthalpy calibrations for the exhaust manifold using one or more of the calibration tables.
