Lambdaa ei tarvitse kytkeä pois päältä, mikäli ecu on kytketty race-moodiin:
Asennusohjeista:
It is recommended to use the Dynojet O2 controller (part
#76125002) in conjunction with the PCIII. This O2 controller
will allow you have full control over the fuel curve by eliminating
the closed loop area. You also have the option of having
your ECU set to RACE mode using the AXIONE tool from
your local dealer. If you ECU is set to RACe mode you do NOT
need the O2 controller.
