Vauxhall C20XE C20LET Motorsport Electronics ME221 ECU with Wiring Loom Package


Designed for fully sequential control of four cylinder engines, as well as forming an integral core to the range of ME221 based PnP ECUs, it’s a feature packed ECU, in a compact, reliable and affordable form factor.

With support for a range of OEM sensors and trigger patterns, as well as being versatile enough to offer flexibility where it’s needed – including often ‘expensive’ features such as Fully Sequential fuel control, Flex-Fuel, Closed Loop Boost & VVT as well as Windowed DSP Knock Control and core features such as programmable inputs, custom tune-able sensor tables and full 3D mapping, the ME221 really blurs the line between lower priced and higher featured engine management systems.

Essentially any port injection, four Cylinder engine, either turbocharged or normally aspirated can be ran semi or fully sequential with an array of Motorsport features to boot, all powered by the ME221 ECU.

This package includes the ME221 ECU, Vauxhall Plug-n-Play Loom, RS232 Tuning Cable & Quick Start Sheet.

The ME221 Vauxhall loom is complete with the stock Vauxhall C20XE/LET (Later 3 pin VR Type) Cam & Crank sensor, Throttle Sensor, and Coil-pack connections. MAP, Intake Air and Coolant connections are a Vauxhall/Bosch mini-timer type.

Note that as with all after-market engine management systems, basemaps are offered ‘as-is’, and dyno tuning is recommended to avoid damaging your engine.
