The Emerald K6 ECU Specification
The K6 ECU was introduced in early 2010 and brought with it new innovations in hardware design. At the heart of the K6 is an automotive specific 32 bit Power PC processor giving class leading performance, stability and durability. The K6 now features 6 ignition and 6 injection drivers, allowing full sequential control for up to 6 cylinder engines, plus the K6 has the best environmental protection of any Emerald ECU to date.
As with previous Emerald ECUs the K6 continues to provide class leading features with intuitive and easy to use software combined with future proof upgrade options. The K6 currently uses the already established K3 PC software providing intelligent and proven functionality and features, such as Adaptive Lambda control, Closed loop Boost and EGT control, VVT control and Triple MAP switching.

Adaptive Lambda control: Self learning fuelling capability
By utilising any of the aftermarket wide band lambda sensors with a capability to output a 0-5v signal the K6’s adaptive mapping capability can be used. Fully user configurable with 3 modes of operation – open loop, closed loop and adaptive you can now have exactly the air to fuel ratio that YOU want anywhere in the speed and load range.
Adjustable speed and load sites: Tailor maps for your engines specific requirements
To deal with specific rpm and/or load related issues that arise on different engines (abrupt airflow changes due to cam timing, TB design or boost onset) the K6 speed and load sites are fully user configurable. Changes made are propagated through all maps and can be made at any time.

Closed Loop EGT control: Adjust boost pressure and fuelling to control port temps
Enhanced Boost control: Tailor boost curves for your needs – variable by gear ratio
