Summary of change:
Audi-AAN/ADU/ABY installs are usually quite easy and smooth nowadays. Rarely (these are almost always home-modified setups) there are some issues. This is one of those cases. There were many trigger errors originally. They changed the 2 VR sensors and the engine runs much better now, but there are still a few trigger errors. '''Scopeshot of crankhome-VR and HALL:''' http://www.vems.hu/files/MembersPage/NanassyPeter/Desmond/desauld_crank_plus_cam.jpg * The crankhome-VR is inside the HALL window. ** but margin is not as great as originally claimed * is the HALL signal captured at the HALL sensor ? Or after the AudiTrigger/CamHALLInverter ? (which is inside the box, so unlikely, but who knows...) ** the factory HALL signal is 5V most of the time. See the image on InputTrigger/AudiTrigger with the German text. ** this HALL signal is mostly 0V. That means '''it would be more noise tolerant without the cam-HALL inverter''' (and 360 degrees offset in config, configured "without cam-HALL inverter" if it is now configured "with cam-HALL inverter") But what kind of HALL sensor is that ? * Factory or some aftermarket sensor ? * Is the HALL sensor in the distributer or at the front of the head at the sprockets ? * What is the exact engine code the HALL sensor and the 1 window wheel came off ? * does the 1-window wheel have a small window, or a giant window (mostly empty, and metal for a few % only ?) Even more interesting is the noise signal. The VR apparently has 4 evenly spaced noise. It looks like ignition (or perhaps, but much less likely injection) noise from a 4 cylinder. But this is a 5 cyl, right ? What is the source of the noise ? Maybe WBO2 ? * It would be interesting to see if the noise goes away if WBO2 and/or idle-air valve are disconnected Do we have a vemscfg actually used ?
