Of course, we got an ethanol content sensor for flex-fuel use. To be able to use some additional sensors for flex fuel and controls for our water injection we got the XS Expansion loom so we could wire these into our ECU. To use all of the features that we wanted to use for our new link system we got some additional parts with our Evolink. The Link Evolink ECU has tons more neat features that you can read about here but these listed above are the ones we are the most interested in for our project. External CAN port for daisy chaining various multiplexed devices: This will help us integrate the ethanol content and wideband air fuel ratio sensor into our system.The OEM Evo ECU is infamous for being sensitive to false knock and the Link’s windowing feature should help avoid this.
By windowing, the user can define the knock sensors operating area where the ECU will look for knock and correct it, this way a lot of false knock correction actions can be avoided.
Having a built-in MAP sensor is a great addition to our system and saves us the trouble of mounting and configuring an external one. On board 4 bar MAP sensor: We are going to speed density to get rid of the weird Karman Mass Airflow Sensor.We want to do a mild version of anti-lag on our car as well. Antilag, launch control and no lift to shift are all available: Launch control and no lift to shift were great additions to our STI and we want to do it on the Evo to aid it’s sometimes-balky shifting.

3 switchable boost control tables: This is going to be very handy with our flex-fuel plus water injection scheme.We will get our car to have a more stable idle with our new Link! OEM Idle hardware supported: Poor idle control with our Cosworth M2 cams has always been an issue with ECU flash.Precision closed loop cam control: So we can take advantage of the Evo IX’s intake variable cam timing to improve low end and mid-range torque and to use to limit cylinder pressure to reduce knock on 91 octane fuel mode.E85, Pump Gas, variable blends of the two and water injection for enhancing performance with pump gasoline and for track use thermal control on E85 and high boost. Up to six fuel and ignition maps: This will be useful because we want to have several operating modes.We are particularly interested in these of the many features the ECU offers. This is going to be very important because we want to run flex fuel and to integrate our AEM water injection into the mix.

Using the Link ECU is now going to give us full control of our engine with its many features. The Evolink is basically Link’s G4 Extreme ECU but with the circuit board modified to fit in the OEM ECU case and the factory connectors to plug directly into the OEM wire harness for an easy and clean as a whistle install. Fortunately for us, Link Engine Managment makes a developed plug and play ECU for our Evo IX that installs right into the OEM ECU housing! We selected Links Evolink IX PLug and Play ECU for our next major upgrade. We wanted more control of our car’s engine but we also wanted to keep the reliable OEM connectors and wire harness and the clean and reliable OEM mounting of everything. It is basically free, community-based shareware. ECU flash is not like a Cobb Access port where the Cobb team continually updates and improves the interface. We also wanted to be able to run flex fuel and this was not possible with the stock ECU in its current development. We also wanted to get rid of the odd and problematic, especially in a car with a big cam, Mitsubishi-centric Karman Mass Airflow Meter. We were having issues with idle control and going into closed loop correctly with larger injectors. One, ECU flash being open sourced does not have all of the ECU’s controls adjustable. However, we had run into the limitations of the stock ECU. We are finally going to a stand-alone ECU in our Project Evo IX with Link Engine Managment! Since the beginning, our car has been tuned with ECU flash, an open sourced tuning solution for the OEM ECU.
