Summary of change:
notes for [https://shop.vems.hu/catalog/vems-motronic55-p-122.html VEMS Audi AAN] (with JPT/55 connector). * See VemsAudiAan * do NOT forget to create your page, see MembersPage ** this is very important '''when deviating from factory (VR/auditrigger) setup''' ** it is even more important if ordering inappropriate and changing from there (request "AAN ECU with HALL/HALL trigger" in the order comment when setup will be modified to HALL/HALL : without this, the ECU is made and tested for the factory VR/Auditrigger setup of course) ** even more important if ordered multiple ECUs with the wrong type (factory VR/auditrigger instead of requesting HALL / HALL) ** it is super-important if any complications appear (eg. no complete success with the first home-converted device). For HALL / HALL sensor, a supply voltage is needed. '''+5V supply is included on JPT55/pin48.'''. * This was requested by customers applying custom solution: HALL / HALL trigger. Those who order HALL / HALL type (because using nonstandard trigger setup) usually know what they are doing. * This way +5V can be easily made available for the HALL sensor (but care might be needed, to not plug in VR sensor, or short to GND) * [http://vems.hu/download/v3/Motronic55/Audi/v3.9AAN/aan_typical_EC10_pinout_hall_hall.doc paper] is included with HALL/HALL device that explicitely mentions this +5V ** this must be considered during install (before plugging in ECU and HALL sensors, '''measure that JPT55/pin48 is not shorted to GND''', resistance must be >150 Ohm, and connectivity from JPT55 to sensor is as desired: HALL signal, GND and +5V). * [http://vems.hu/download/v3/Motronic55/Audi/v3.9AAN/Triggers_assebly.pdf trigger_assembly.pdf leaflet] and [http://vems.hu/download/v3/Motronic55/Audi/v3.9AAN/ some v3.9AAN illustrations] might be helpful to get some idea about the differences of standard VR/auditrigger setup, and when "AAN ECU with HALL/HALL trigger" requested ** download latest version '''v3.9 AAN HALL / HALL''' looks like : http://vems.hu/download/v3/Motronic55/Audi/v3.9AAN/assembled-Bottom_HallHall_m.jpg The RQ13=0 Ohm (slanted) can be replaced by a small wire. * The '''red wire at the bottom connects +5V to JPT55/pin48'''. ** red wire is '''not required if the JP22''' is present and middle to bottom is shorted (the middle to bottom solderblob does the exact same thing; but JP22 is only available on v3 srl>10520). Bottom side (of bare board, before customized to HALL / HALL), some trigger related components annotated: http://vems.hu/download/v3/Motronic55/Audi/v3.9AAN/trigger_bottom_hall_m.jpg ---- In case of any problem (or suspected problem), follow * [https://shop.vems.hu/catalog/refer_to_thematical_page.php Tech request] * eg. specify intent (eg. "I accidentally ordered the standard type with factory trigger, and want to convert device srl/... from oid/...) from ... to ... * detail what modifications made (yes, step-by-step, even if repeating some docs) * measurement results (eg at JPT55 and sensor pins) * (latest) photo of result * triggerlog (with annotation, eg. sectrig enabled as camsync in config, but sectrig pulses not seen) ** for convenience, you can take notes on this page for now (will clean it up later) If a conversion is not success, do NOT apply same to other devices (that would risk causing damage). ---- '''Conversion notes, measurements, photos''' ... add your notes... [http://vems.hu/files/MembersPage/LabeFahrzeugtechnik/v3.9AAN_HALL_HALL/ photos from customer, with partial conversion] - important areas highlighted Since than: * R30=4k7 (assumed to be applied, please confirm) * remove SJ7 (done on the photo) * '''remove R248''' - remove some hotmelt to access * '''install R48''' * ... anything else done ? measured ? Note: * v3=10585 '''originally only this was mentioned to be converted''' ** although not reported any other device serialnr, suspected that v3=10505 and v3=10519 also attempted ? ** these (AAN with srl less than 10520) might not have JP22
