Summary of change:
'''400kPa Voltage / kPa table''' 0.2 -> 4.8V for 20kPa absolute -> max pressure '''LINEAR''' => basic math => any intermediate values, or table with any number of points. On paper, or with formula in xls, or Octave / matlab : <code> V=[0 : 0.2: 5] # For the 400kPa sensor this means 20-400 kPa : kPa=(V-0.2)*(380/4.6)+20 [V', kPa'] 0.00000 3.47826 out of precise range 0.20000 20.00000 min REFERENCE point 0.40000 36.52174 0.60000 53.04348 0.80000 69.56522 1.00000 86.08696 1.20000 102.60870 1.40000 119.13043 1.60000 135.65217 1.80000 152.17391 2.00000 168.69565 2.20000 185.21739 2.40000 201.73913 2.60000 218.26087 2.80000 234.78261 3.00000 251.30435 3.20000 267.82609 3.40000 284.34783 3.60000 300.86957 3.80000 317.39130 4.00000 333.91304 4.20000 350.43478 4.40000 366.95652 4.60000 383.47826 4.80000 400.00000 max REFERENCE point 5.00000 416.52174 </code> ---- '''MAP-board 1.0''' Important: the pinout of '''internal sensor''' can be found on GenBoard/Manual/Wiring/ManifoldAbsolutePressure http://shop.vems.hu/catalog/images/MAPdongles_and_bare_s.jpg '''Pin1''' (of the black SSC-male connector) '''is the leftmost''' on the above picture (you can verify the pin numbers printed on the female). The packaged sensor is '''casted with epoxy, very durable, you can step on it''' or melt the external softer black part without damage to the internals. The '''400kPa version''' is recommended for > 130kPa (1.3bar, 18psi) boost. On the 12V, 400kPa version, there are some simple extras onboard, like * regulator (so it can be powered from 12V and there is a 5V output) * thermometer (Temperature output) You can tell the different versions by the number of actually present SSC pins (3/4/5). ---- '''Pinout of the 12V, 400kPa version''' - most popular Note that populated this way, the supply has a wide range, and the '''5V is output, not input. Applying 5V to the 5V output is not supported, it might damage the unit. Use the 5V version if you want to power something from 5V (max 50mA)'''. This version has (all) 5 male pins (none missing). ||'''SSC pin'''|| '''recommended color'''|| '''signal''' || '''range''' || '''note''' || ||1|| white || MAP output || 0.2 .. 4.8V || 20..400kPa || ||2|| brown || GND || 0V || || ||3|| red || '''5V out''' || 5V || max 80mA.
