Ecumaster Lotus K4 Plug in ECU
This plug-in solution for the Lotus S2 K4 Rover engine offers a reliable replacement for the often-failing OEM ECU, which is currently unavailable from Lotus. Built on our trusted Ecumaster Black platform, it provides precise engine control and includes wideband lambda control for optimal performance. Explicitly designed for track-oriented vehicles, it also allows for the integration of additional sensors and can be connected to modern data systems or displays through CAN bus connections, offering a larger range of channels.
Also all engine parameters can be logged with an additional EDL1 logger available here.
Ecu is supplied with a starting map that is ready to plug in and go.
Ecu is supplied with a link loom for a wideband lambda sensor that can be provided separately. The Lsu 4.9 sensor is available here
Please note you will need to replace fuse number 8 7.5A with 10A
