Custom designed and manufactured immobiliser bypass emulators board programmed for the Range Rover P38 GEMS 4.0 and 4.6 engine ECU. Suitable for the GEMS engined Defender or Range Rover P38. Ideal for standalone engine conversions, off road / track competition cars or even as insurance just in case the BECM security system throws a sulk and you get the dreaded "Engine Disabled" message and the engine won't start (a wiring mod to the stock loom is also required in this case to get the starter motor to crank). Note: Requires a Nanocom or Hawkeye or similar dealership level coding tool with the security learn function to synchronise the ECU to the board. Fitting instructions can be downloaded on my website here: https://www.ecux.co.uk/downloads/GEMS8-Emulator-fitting-instructions.pdf Any questions or queries, please contact me. Worldwide postage outside of the U.K. is £10 International signed for.
