The ME221 Plug-In ECU range offers all the features of the ME221 platform with the convenience of using the factory harness and sensors to give a quick install time on a range of vehicles, while still allowing upgrades such as MAF-less fuel control, turbocharging or throttle body installs to be carried out.

The ME221 S2000 Plug-In is the latest Engine Management System for the 2000-2004 Honda S2000 (AP1).

This convenient plug-in ECU is designed to replace the original circuit board within the casing of the vehicle's factory ECU. The ECU retains the original connector, allowing for a straightforward installation process. The OEM ECU casing provides protection and ensures a clean, factory-like appearance. By fitting inside the original casing and utilising the original connector, the ECU offers a discreet and efficient way to upgrade the engine's control system.

With this type of plug-in ECU, you can enjoy the benefits of enhanced engine performance and customisation without needing to modify the wiring harness or perform extensive rewiring while maintaining full OEM functionality!

It supports the stock dash cluster (including coolant gauge) and gives full VTEC tune-ability. The only extra thing you need to do besides plugging it in is run a MAP vacuum hose (supplied) from the ECU to the intake manifold.
