Chip for Rover 14CUX Hotwire systems with latest version of code with tune resistor selectable fuel maps.

This chip contains the latest factory firmware modifications for your Rover fuel injection, and adds the ability to select the fuel map based on the external tune resistor.  Please note that not all hotwire wiring harnesses have the tune resistor wiring in place. If your hanress does NOT have the tune resistor wiring and you use this chip, your system will default to map zero, the "limp home" map.  If you want to have the latest code but your harness does not have the tune resistor wiring, please check out our "internal resistor tune chip" service, or add one of our ECU wires to be able to use the external tune resistor.

This is the bare chip only; you must be comfortable working with electronics to install this chip. Buyer assumes all risk. If you are not comfotable, check out our chipping services.

This chip is primarily intended to assist those installing Rover V8 engines with 14CUX based "hotwire" injection in conversions such as the popular MGB V8 conversion, without catalytic conversions. Be sure any fuel injection chip changes are legal in your jurisdiction if you intend to use this in a street car.
