This configuration applies only to the LT1 engine itself and does not include any vehicle-specific settings. Be sure to configure all additional components such as the low-pressure fuel pump, cooling fans, starter, and other auxiliary systems. Stock engine (no internal modifications) Exhaust system without catalytic converters Two LSU 4.9 sensors installed in the downpipes (OEM oxygen sensors are not supported) The map was calibrated on a dynamometer: Power: 500 HP Torque: 670 Nm Setup Details: ECU: EMU PRO 8 + GDI Driver The attached map controls the following: GDI injectors GDI high-pressure fuel pump Alternator control using a PWM signal Control of the oil pressure solenoid (with the control deactivated, maximum oil pressure will be delivered) Electronic throttle controlled via the SENT protocol Fuel rail pressure sensor with SENT protocol (3 pin sensor) VVTi solenoid control Non-mapped or unsupported features: No support for Displacement on Demand (DoD) - leave disconnected This configuration is only for the LT1 engine itself. It does not include any vehicle-related settings. Remember to configure vehicle related components such as: the low-pressure fuel pump, fans, starter, and so on. Note: This engine is available in two versions of the fuel rail pressure sensor - one with the SENT protocol (it has connector with 3 pins) and the other a classic analog type (it has 4 pins). The project includes the configuration for the SENT sensor. If using the analog sensor (4 pins sensor) below is the calibration: Voltage: 0.5; 4,5 Pressure: 0.0; 250.0 For more details see the Technote: https://ecumaster.com/files/EMU_PRO/Base_Maps/LT1_GEN_V/GM_LT_1_GEN_V_High-pressure_Sensor.pdf Assignment of wideband oxygen sensors: Lambda 1 is on Bank 1 (Cylinders 1-3-5-7) Lambda 2 is on Bank 2 (Cylinders 2-4-6-8) GDI Driver pinout: Injector A - Injector 1 Injector B - Injector 6 Injector C - Injector 8 Injector D - Injector 5 Injector E - Injector 7 Injector F - Injector 4 Injector G - Injector 2 Injector H - Injector 3 Pump 1 - High Pressure Fuel Pump - SENT 1 - Throttle Position sensor SENT 2 - Fuel Rail Pressure sensor Revision history: 2025/11/12 v1.0 Initial release - GDI injectors - GDI high-pressure fuel pump - Alternator control using a PWM signal - Control of the oil pressure solenoid (with the control deactivated, maximum oil pressure will be delivered) - Electronic throttle controlled via the SENT protocol - Fuel rail pressure sensor with SENT protocol (3 pin sensor) - VVTi solenoid control
