Injection Systems
Lucas 13CU support.
Support for early Lucas 13CU multiport systems used on Rover V8 applications, with diagnosis-first service planning.
13CU Profile
Early MFI control with limited self diagnostics.
- Land Rover Range Rover Classic era application support (1987-1988)
- Limited on-board self diagnostics and volatile fault memory behaviour
- Adaptive short-term fuelling offset checks per bank
- Injector, airflow and sensor-path validation before replacing parts
13CU systems benefit from structured baseline testing first, especially where running faults are intermittent or age-related.
Key Notes
Common service checks for 13CU vehicles.
Fuel injector baseline
13CU injector sets are typically assessed for consistent pressure-drop response across the full bank before component replacement.
Throttle and idle control
The stepper idle system and throttle body condition need to be checked together, not in isolation.
Sensor health
Coolant and fuel temperature signal plausibility is critical on older harnesses and connectors.
Share your current symptoms and vehicle setup and we can help map the next checks for your 13CU system.
