ECU location and installation
Stock ECU is located in engine bay on driver side.
1.Remove the plastic guard where the ECU is located.
2.Disconnect battery from vehicle.
3.Remove and disconnect stock ECU from vehicle harness.
4.Install MaxxECU adapter harness.
5.Route the included MaxxECU MAP-sensor hose to the intake manifold and connect into the MaxxECU.
6.If your vehicle have LSU sensor(s) mounted from factory (see vehicle cover list on the top if this page), skip the next step.
7.Install the included lambda sensor in exhaust and route the wide band lambda cable to the MaxxECU unit and secure the DTM 8 connector.
8.Your MaxxECU unit is preloaded with the correct basemap for your vehicle.
9.We assume you have read the included Quick start guide, and now it's time for the engine start.
Note: MaxxECU RACE plugin ECU kit, might not fit into the standard plastic ECU box. Make sure to mount the ECU away from heat or water!
Most people do route the adapter harness inside the car, and only let the adapter harness and stock ECU connectors be left in the plastic box in engine bay.
