Wiki-spamming is not tolerated, will be removed, so it does NOT even show up in history. Spammers go away now. Visit Preferences to set your user name Summary of change: '''MAP-sensors''' '''Important: check''' GenBoard/Manual/Wiring/ManifoldAbsolutePressureExternal for the '''pinout of packaged external sensor''' (though 5V packaged is pin-compatible with the bare sensor). http://shop.vems.hu/catalog/images/MAPdongles_and_bare_s.jpg The "bare" version (top-left of the above picture) is ment to be mounted in the ECM case: The adapter is designed to carry the 400kPa MPXH6400 sensor. Motorola packages this nice sensor in SMD only, so a PCB was necessary for a clean install. Output is compatible with the more common MPX4250AP sensor, but '''features 400kPa range''' instead of 250kPa. Recommended for > 130kPa (1.3bar, 18psi) boost. there are some simple extras onboard, like * regulator (so it can be powered from 12V and there is a 5V output) * thermometer (Temperature output) ---- '''Mounting the 5V "bare" version''' The "bare"-board is '''ment to be mounted vertically in the Alubos case, perpendicular to v3.x''' http://www.vems.hu/files/MAF_MAP_BAP/MAP_400kPa_mounting_m.jpg The image is taken before hotmelt is applied (at the connection of the boards and the sensor nipple). When mounting onboard GenBoard/VerThree, for mechanical stiffness: * '''solder all 6 pins (with bent leads)''' of the 90degree header that connects the boards * the sensor nipple points directly towards the "VIV" type pneumatic connector mounted on frontplate: this secures the mounting ** the screwholes are normally not used, at least not to secure the board against v3.x. The sensor would point down (towards the board -would be quite useless) if these screws were used ! * some hotmelt glue (after testing) helps for extra ruggeddness * '''Note that this sensor has small 5x3mm nipple, so''' ** either the smaller 5x3 mm VIV connector is needed (mounts in drill dia=7mm. Rarely used.) ** or '''use VIV6453 pneumatic connector''' (5/3mm on one side and 6/4mm on the other side, it mounts in drill dia=10mm. This is used normally.) ---- '''Internal "bare" version is only practical with 5V supply, to match the supply provided by the GenBoard/VerThree header'''. It's possible to order the "bare" board with 12V supply, for other applications, if you really know what you are doing. '''Pinout of the 5V, 400kPa version: "bare" or packaged''' || '''pin nr.''' || '''signal''' || '''range''' || '''note''' || || 1 || MAP output|| 0 .. 4.8V || 20..400kPa || || 2 || GND || 0V || || || 3 || '''5V in''' || 5V || max 10mA || || 4 || temp out || 0.5 .. 4.5V || only for the 400kPa version; NTC U(T) curve: similar to coolant sensors, 2.5V at +25C || || 5 || GND internal || 0V || || The bare, internal version also has a 6th, not connected pin (so it mounts nicely on the 6 pads of MPX4250AP). ---- '''Pinout of the 12V supply, 400kPa bare version''' - you likely don't need this type. Either buy packaged, or buy the bare with 5V supply. '''Important: while the 12V supply is a nice option for the external GenBoard/Manual/Wiring/ManifoldAbsolutePressureExternal, for the internal the 5V is what you likely need when used inside the v3.x case. The 12V is only for special applications, not suitable for direct mounting on GenBoard/VerThree. 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.''' || '''pin nr.''' || '''signal''' || '''range''' || '''note''' || || 1 || MAP output || 0 .. 4.8V || 20..400kPa || || 2 || GND || 0V || || || 3 || '''5V out''' || 5V || max 80mA.
