Alright guys, a beautiful thing has happened. We've been selling the earlier generation NA/NB Motorsport Electronics stand alone units for the past couple of years and there isn't a better company to work with. Truly class act customer service and very capable hardware.  A year ago, we requested their team shed some light on the NC platform and months later we had an operating prototype in our 2013 Club. After a base calibration was produced the team hit the ground running with creature comforts to produce a very well rounded firmware that orchestrates the chassis seamlessly. And here we are...

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. The estimated delivery date is May 2020. We will only have a limited number available at that date, so paying a deposit guarantees that yours will be one of the first delivered. Deposit holders will also receive a £100 discount on the final unit (£995 inc VAT instead of £1095 inc VAT). You are no longer limited by the stock ECU that traditional MX5 NC remap solutions have to work with.  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.
