Summary of change:
'''WideBand/Connector''' http://vems.hu/download/v3/doc/WideBand/Dual_wbo2_connection_to_VEMS_v3.jpg Don't forget to write in order comment if you "need 2nd WBO2 sensor inputs" * The EC18 pins of the 2nd wideband are hijacked for wheelspeed, analog in and GND by default '''[http://shop.vems.hu/catalog/wideband-connector-p-57.html WBO2 connector available here]''' * slide in the recepticles * push in the backout fastener (otherwise you cannot plug in the sensor!) '''Calibration of 2nd sensor in VemsTune Tools / Wideband calibration''' (as usual, see VemsTune help) * label the 2nd sensor, and temporarily connect the 2nd sensor to the '''first WBO2-female''' * calibrate * take note of '''calibration value''', and write it to the '''calibration of 2nd sensor''' * unplug sensor from 1st WBO2-female, and connect it to second WBO2-female. * than calibrate sensor1 normally (connected to first WBO2-female). ---- Don't forget to change config.wbo2_calibration when you change sensor. GenBoard/VerThree has a precise calibration scheme, that depends on setting this ('soft') variable, and it does not read the (hardware) RCal in the sensor housing. (although GenBoard/VerThree can be used as a repair-station WBO2 controller, it's primary goal is engine management, where you rarely change sensor: LSU4 lasts for >100000 km) ---- '''WBO2 Connector Sources - are these solved perfectly now ?''' The current source for WideBand connectors is waay too expensive. The plug (is it the male or the female?) says tyco >PBT-GF30< 0-1475050-1 I queried tyco (they couldn't answer easier questions earlier, but we'll see). The ''counter part female connector of LSU4 is made by Sumitomo''. Connectors for this sensor (2 rows of 3 pins) Can be purchased from www.impexfap.com, 1stvwparts.com, or a local VW dealer. Prices are a bit high. 1stvwparts.com is the lowest of the 3. Connector part numbers: * You need (1) 1J0-973-733 Connector Housing * You need (3) 000-979-133-A Wire with 2 terminals ** You can try to find the bare terminals and crimp them youself, which will yield a neater install. * You need (6) 357-972-741-A seal/grommet. This is now superseded by 1J0 972 741 A. Update: seal ordered has no central hole. Error here somewhere. ---- ''TODO:'' Some more WBO2 (2x3) female research would be nice. * GenBoard/Manual/WBSensorConnection * pinout and sensor stuff: http://www.wbo2.com/lsu/default.htm
Optional: Add document to category:
Wiki formatting: * is Bullet list ** Bullet list subentry ... '''Bold''', ---- is horizontal ruler, <code> preformatted text... </code> See wiki editing HELP for tables and other formatting tips and tricks.
