Recommended mod:

For the curious, About the other 5 holes:

First input tests:

Than verify in InputTrigger/TriggerLog


done as per pic

moved the resistor so it looks as above

connected the red line in the above pic

got 5 v at signal and verified it by putting 1k resistor between signal and supply and got 1.5 v

thank you

done the wiring, connected the pc using a usb ftdi cable, updated the ini files on the software then i have done the wiring according to the vanos in

http://vems.hu/download/v3/Motronic88/325-M50-vanos-and-nonvanos_OBSOLETE.xls

and used

http://vems.hu/download/v3/Motronic88/base_M50_vanos_1.2.31.vemscfg

the car is a 92 m50 i imagine it has vr primary sensor

which according to above pic my ecu is vr primary(how do i confirm on car )

on the primary trigger there is 3 pins 3 wires

i have connected the yellow wire to ec36-27(thats the only sensor connected) and connected the black and shield to same ground. when i power on just ecu to record trigger log it says no inputs connected

ec36-27 shows 5v out

the crank sensor reads .519 KOhms across signal and ground so it is working.
