We highly recommend Ecumaster EMU Classic ECU's for use on C20XE / C20LET / N.A / Turbo builds. We use use these with all our own in house builds where standalone engine management is required.

ECUMASTER EMU Classic is an advanced engine management system controlling operation of multi spark ignition engines. It controls all aspects of the engine, and provides emergency procedures in case of failure or incorrect operation of sensors. Using the latest technology in the field of electronics and software, the device has a very high potential and attractive price. With all the features probably one of the best value for money device on the market.
