Description

Based on the ME442 ECU, this version comes with a high quality patch harness that plugs straight into the factory loom of your MX5 NC/Mk3. It retains all the factory functions, except cruise control. This is an early unit, so not all functions might be working. Final release will be in May 2020.  There are many advantages which include:

  • Real-time tuning, resulting in better maps and a much improved tuning process
  • Electronic boost control (much better spool, possibility to do boost-by-gear)
  • Support for any aftermarket race dash (CAN-based)
  • Engine-saving features based on any number of sensors (oil parameters, fuel pressure, AFR etc)
  • Flex-fuel and a myriad of other configuration options not available with the stock ECU

The ME442 ECU is a feature rich and future proof four, six and eight cylinder injection engine management system. Built from the ground up using the latest control strategies means a modern, powerful, VE based ECU, with enhanced feature set including closed loop boost, in-built Wideband Lambda Control, DSP Knock Control, on-board data Logging and VVT control – all in a compact form factor. Massive IO means the ME442 can handle anything thrown at it, and custom tables means any specific algorithms required can be easily derived.

Note: The MX5 NC version of the ME442 will be locked to only 4-cylinders and only to the MX5 NC trigger patterns. Price includes all features and required software. There’s no hidden/costly unlocks or extra charges for the tuning software.

Core Charge: The £100 Core Charge is for return of your stock ECU. We recommend you claim this back after you have had your car tuned as once returned to us the OEM ECU will no longer be serviceable. Please contact us to arrange this credit when ready.
