    (without influence from outside) to work in. An engine or chassis dynamometer gives a more precise calibration for your (racing) applications. The KMS MA5 ECU offers a complete self learning air fuel ratio control (lambda control) for most common types of oxygen sensors (Wideband/narrow band).
  • Page 4 WARNING: Disconnect the battery cables when you’re doing electrical work. Disconnect the KMS ECU from the wiring harness connector when welding on the vehicle. Make sure there are no fluid leaks and all connections are secured and/or tightened. Wiring and fuel system components must be mounted away from heat sources or shielded if necessary.
