A  basic diagnostic USB PC  6ft cable that plugs into the unique OBD socket found on the 14CUX series ECU loom known as the "hot wire" used on many Rover V8 engined cars around the early 1990's for use with the RoverGauge freeware diagnostic software. The original locking Lucas TTS connector used on the OBD connector are now proving hard to find , so this cable has a simple 3 pin connector that's a push fit into the 5 pin white TTS connector found in the loom shown in the photos.


 RoverGauge software allows you to read all  sensor data - Engine temp, fuel temp, speed, RPM, Voltage, Lambda trim, Throttle pot, AFM voltage, idle status, live fuel map display, fuel pump status, injector pulse width, and stepper motor position. It also has stepper motor control and fuel pump control inputs. Full range of ECU fault codes. Sensor data logging facility and Eprom copy function.  If you are interested in mapping the fuel map  display will allow you to see the current load point, that can now be altered with software like Tuner Pro using  a suitable  Eprom emulator like the Moats Ostrich . RoverGauge  runs on Windows XP, Vista and Windows 7 , 8  and 10. To run on an Apple it needs a Windows 7 emulator like VMware Fusion.  This cable will save hours of trouble shooting, garage trips, and guesswork for anyone running the 14CUX ECU. 

This is just the basic cable without LED display  and NO software, but please see my other listings if you just want the complete software kit with 14CUX diagnostic manuals. I can also provide full technical backup on anything 14CUX or RoverGauge related so you can buy with confidence.


  Please note a few ECU looms around 1990 do not have the TTS connector, and use a  white square 6 pin connector.(typically used on the factory MGBV8) so if you cant find the TTS connector, have a look  for this square connector.  It looks the same as the black connector used for the fault code reader, but is made from white plastic instead. If you need the MGB cable please contact me .

 RoverGauge freeware  download https://github.com/colinbourassa/rovergauge/releases

Note: Download and extract the files to one folder on your hard drive. RoverGauge.exe must be run from within the folder, it cant be run without the associated files. It will run without a cable if you want to see all its functions, but obviously wont connect to the ECU.

This cable is NOT compatible with the P38 series  V8 Range Rover fitted with the GEM's engine management system.
