Checked against the USB tool on the bench (3210 rpm): - O2: raw x 5/256 V (raw 195 -> 3.81 V, as the USB tool shows). - New derived sensor: injector duty = INJ ms x RPM / 1200 (16.67 ms @ 3210 rpm -> 44 %, as the USB tool shows). - Default dashboard flags: MIL, Fuel Pump, FAN Out, VTEC Out (the requirement's "FuelCut" is the fuel pump flag on the S300). - Log one raw frame (bytes 0-63) every 5 s so USB-tool readings can be matched to bytes; INJ, IGN, TPS, MIL, AF and PA still need that check.
