no RPM

[Bambi]

HI

I'm not getting an rpm signal with genboard 3.6 on a URS4. Works fine with a 55 pin motronic unit though. I made a harnass connector between the car's 55 pin motronic and the genboard 3.6 using  the following pinout:

19   EC36-32   GND5   Ground #3 (0V) (Solder on the bottom side)
20   EC18-10   Stepper-B   Power output stage for ignition, cylinder #4
21   EC18-04   Stepper-A   Power output stage for ignition, cylinder #5
22   EC36-15   p259-5   CEL check engine light
23   EC36-11   Ignch4   Power output stage for ignition, cylinder #3
24   EC36-32   GND5   Ground #4 (0V)
27   EC36-25   VBATT    +12V Ignition ON (Terminal 15)
29   EC18-02      Knock Sensor 2 (AAN: cylinder: 4,5)
30   EC36-26   GND   0V Reference Signal (AAN: sensor)

37   EC36-23   Flyback   +12V battery feed, via Fuse S28
40   EC36-04   P259-ch0   Tachometer signal (to Instruments & Autocheck)
44   EC36-02   MAT   Intake air temperature sensor, 429 Ohm pullup
45   EC36-14   CLT   Coolant temperature sensor
47   EC18-12   LM1815sectrig   Crankshaft position sensor 62 BTDC cyl1
48   EC18-17   GND   Reference point for engine speed and crankshaft position sensors
49   EC36-27   Prim. Trigger   Engine speed sensor 135 cranktooth

Any idea where to test for a problem?

first remove spark plugs, disconnect coils and injectors, then crank, try to record trigger log, what firmware what configuration do you have? look when you are cranking do the indicator running on lights up? try to disable sec trigger and crank it then.

[Bambi]

running 1.1.81

I recorded log and config files here: http://vems.hu/vemstune/bugreports/reports.php?cmd=view&key=MDAnpV

[Kamuto]

did you made trigger log? and better upgrade firmware and vemstune

[Bambi]

Is recording the triggerlog the same procedure as normal logging?

No, recording trigger logs is done with a tool in the tools menu.
