ECU / Programming Information

The second-generation Rolls-Royce Ghost uses the BMW/Rolls-Royce N74B68 with Bosch MG1-family engine management.

Verified tuning references show Bosch MG1CS201 support on Ghost applications, while other N74B68 Rolls-Royce applications are also found with MG1CS024.

Because ECU type and protection level can vary by software and production date:

ECU identification must be confirmed before programming.

Do not assume the programming method solely from model year.

Programming Process

Before tuning, provide:

• VIN
• Vehicle year
• ECU identification
• Current modifications
• Fuel octane
• Current DTC codes
• ECU read / tool identification where applicable

Depending on the ECU version, the ECU may require bench identification, unlock or bench programming before the modified software can be written.

Additional Calibration Options

Depending on ECU software and vehicle configuration:

• Catalyst-related calibration
• Cold-start / secondary-air related calibration
• EGR-related calibration where applicable
• Specific DTC removal
• Speed limiter changes where supported
• Other software-specific functions

Exact DTC codes must be supplied for DTC-related changes.

Important Notes

Performance figures are representative and can vary with fuel quality, vehicle condition, ECU software, hardware configuration and operating conditions.

Software tuning does not repair mechanical or electrical faults.

ECU type and programming method must be confirmed before work begins.
