Rover V8 EFI reprogramming

Early V8 Land Rovers and Range Rovers are equipped with the Lucas 14CUX fuel injection system. This system is also referred to as the “hotwire” injection. When changing something of the engine, such as the intake, heads, compression or exhaust, the engine management should be adjusted accordingly to have an optimal combustion. Since the 14CUX ECU is not reprogrammable this is not a straight-forward task. Lemmen Engineering has the tooling and experience to do real-time remapping of a 14CUX injection system on a rolling road. Specifically for off-road rally racing cars. Adjusting the injection system on a rolling road ensures that the injection system is perfectly adjusted for the engine, resulting in optimal power, reliability and fuel economy. We can do performance engines as well as road-going cars.
