IMPORTANT: enter the case-INsensitive alphabetic (no numbers) code AND WRITE SOME SHORT summary of changes (below) if you are saving changes. (not required for previewing changes). 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: '''BMW S54''' According to our knowledge, for S54, it's enough to just * set up measurement * and verify that the configuration+wiring makes the '''desired cam''' (this was verified, but please take note of wiringbelow) ** move into the '''desired direction''' (this wasn't verified, and very likely to be reversed) ** messing up either will cause the control to not work. * according to: [http://vems.hu/vt/help/v3/v3_camshaft_angle_control.html VT help] ** see the Dual Vanos Output type: Measured = 0 ... target - 2 deg - PWM-ing range : '''OutputA active''' and OutputB inactive , '''when Cam pulse too late'''... '''So OutputA should be connected to the actuator that advances the cam when activate''' We'll see if this engine happens to show something tricky. ---- '''Trigger''' VR, HALL, HALL * primary trigger VR 60-2 * sectrig HALL: missing 8-1 (exhaust cam) * thirdtrig HALL: 6 evenly spaced tooth (intake cam) ---- '''Cam actuators''' * manually actuated outputs actuate the cam, but * not configured properly ---- '''Cam actuator wiring: FILL IN''' * * * * ---- '''Trigger errors''' '''Engine is running well''', but trigger error is lit continuously... * sectrig position measurement ? ** '''position change not seen even when manually actuated (and cam obviously moving)''' * third trig measurement ? ** position change not seen even when manually actuated (and cam obviously moving) ---- http://vems.hu/files/MembersPage/poweredracing/BMW_S54/2txps54cam.png ---- '''triggerlog ?''' Note: [http://vems.hu/filethingie.php?action=list&subdir=MembersPage/poweredracing/BMW_S54/misclogs old log files] were not captured with this method, and not suitable to reproduce what is going on. Capture triggerlog: * start capture triggerlog (preferrably 115200 baud) * starting engine (this should be in the log) * advancing cam (actuating manually) * engine might stop because of this * don't forget to name/annotate the log, taking note of what is happening, so it's possible to find (among dozens of other) * preferrably a vemslog should be captured with similar sequence (it's another attempt, as it's not possible to capture 60-2 triggerlog and vemslog at the same time because of baudrate limitation) 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.
