Maybe I didn`t write correct. I haven`t change o2 sensor, I use information from stock narrow band. Only what I made more I blinded PAIR system, to have correct information from o2 sensor and reach good AFR. I haven`t palyed with engine break yet. RB harness has one main connector to ECU and others to TPS, o2 and crankshaft sensor. What they haven`t made in this harness, they didn`t get connector to gear sensor position. I`ve installed RB QS which work much better then stock one. I attach instruction how to install RB on gen 8 - which is the same as in PC.
