Trigger related subpage of MembersPage/BasilDaham/CordobaSX (original) actually MembersPage/StuFrench (new setup ?)
Apparently spent weeks (or months), and generated [1000 lines at the VEMS UK forum] of text (totally unsuitable for good overview), but the trigger setup, wiring and measurements are starting to shape here now, good. Investigation can start this way.
The v3 #671 was replaced after damage, #1746, (theoretically HALL, HALL trigger)
Primary trigger HALL 60-2
At TDC tooth 15. (tooth0 is the tooth selected edge after missing tooth, tooth10 is 6 crankdeg later, etc...)
verify the internal pullup resistor
- temporarily connect a 1k resistor between EC36/27 and GND
- measure voltage. (above 1V for strong pullup - preferred for HALL; below 500mV for weak pullup - preferred for VR).
Than measure how the EC36/27 voltage changes when you rotate engine (push car in gear5).
Verified via DVM and scope:
- down to 0.1V or so VERIFIED. (Why don't you write exact measured voltage ?)
- and up to 3V or above VERIFIED. (Why don't you write exact measured voltage ?)
Than you need to publish details about your setup IssueReports
for checklist
- firmware
- mcd / mct dump
- logs
- etc...
It might be something simple, but publish these first [* Not entirely sure how to do this step and obtain logs, mcd / mct etc?!]
Secondary trigger HALL
Hall-effect sensor on camshaft for camsync (1-window trigger wheel)
- My Secondary trigger is disabled as I'm running the primary only
