Summary of change:
'''installing VEMS V3 on BMW engine M73B54''' I'm using '''crankshaft sensor VR with 60-2 tooth''' and waste-spark ignition I have '''issue with the crankshaft sensor. During cranking I can't see any readings from the sensor'''. * What is DC voltage measured on EC36/pin27 ? * I test the sensor with othere electronicks and it is ok. What setup do I need to make to the ECU? I directly connect the sensor to the VEMS on PINs 26 (GND) and 27 (VR +). I test it in both directions (I swap the two wires on pin 26 and 27) and no improvement. * seems OK, but read on ---- '''Ground connections ?''' * GenBoard/Manual/GroundConnections P259 outputs are OK ? * sometimes insufficient GND kills p259, which prevents LM1815 +5V (symptom is no trigger pulses seen) ** in that case fix harness GND, remove or replace p259 ---- See also MembersPage/MSeventyThreeVeeTwelve
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.
