""Nissan 200sx S13 CA18DET - WBO2 / A Fresh Tiny (AFT hereon) Install"" ---- AFT to Nissan ECU (ECCS) Wiring Pinout ||Function||AFT 15 Pin Plug||Nissan ECU|| ||RPM Signal||10||7 Y/R|| ||Misc In Signal||8||27 - G/B for AFM or ?? LtG/B for TPS|| ||Lambda Out||1||29 - W|| ||Lambda Ground||9||Ground|| ||Live Wide band||Live||Stereo Blue wire|| ||Ground Wide band||Ground||Ground|| '''Measuring the Tacho voltage''' RPM signal wire voltage measurements - 0.33volts live and 1.27volts with the engine running. Observations/Issues 1) Connecting the gauges Misc In to either the AFM or the TPS causes the engine to hunt at idle and stall at junctions. Suggestions - wire in line with 10k resistor. Result = Car no longer hunts at idle, however in Megatune, Misc in gauge does not react appropriately, nothing logged to log file for Misc. 2) Pressing the button on the Gauge to cycle display causes momentary drop in revs and lambda. See Attached. http://www.kardiak.co.uk/gal/200/gauge/4buttonpress.jpg http://www.kardiak.co.uk/gal/200/gauge/pressbutton4times.log 3) During logging gauge will occasionally log that RPM is 100 (see above pics/log) for one or two entries, this is sometimes accompanied to by a lambda spike, cannot get a proper TPS trace at the moment (See 1) in order to correlate where these occur. ---- Runs 2nd Gear 20-60 http://www.kardiak.co.uk/gal/200/gauge/2ndGear20to60.jpg http://www.kardiak.co.uk/gal/200/gauge/2ndGear20to60.log
