Simon Posted November 6, 2016 Report Share Posted November 6, 2016 Hi Piar Can you confirm the number of teeth on the cam shaft for the cam position sensor? Quote Link to comment Share on other sites More sharing options...
Piar Posted November 7, 2016 Author Report Share Posted November 7, 2016 there is 8 teeth on camshaft Quote Link to comment Share on other sites More sharing options...
Simon Posted November 7, 2016 Report Share Posted November 7, 2016 I notice that you only have one aux out assigned to the cam control I would have expected 2 on the BMW.If you unplug the control solenoid do you get a stable set of figures?

Piar Posted November 7, 2016 Author Report Share Posted November 7, 2016 I have tested this versionbut anyway i can't get stable set i have retarded\advanced cam already Quote Link to comment Share on other sites More sharing options...
Piar Posted November 7, 2016 Author Report Share Posted November 7, 2016 I have connected signal from inlet camshaft sensor(which shows real cam angle) to trigger 1 and run oscilloscopeIt have wrong polarity? I have changed polarity on sensor but i have no lucki still have not stable values on cam angle testas we can see we have 8 teeth on camshaft bmw vanos testing_with changed polarity.llg Quote Link to comment Share on other sites More sharing options...
Piar Posted November 7, 2016 Author Report Share Posted November 7, 2016 problem sovedI have assigned VVT inlet Lh function to Trigger 2 and di2(which actually shows camshaft position)When i turned off trgger2 vvt function - everything stabilized and started to workexcept vanos) i think it in bad conditionbecause it can not hold targetinstead of 10 degree it instantly open to it's maximum and closing very long Quote Link to comment Share on other sites More sharing options...
Scott Posted November 8, 2016 Report Share Posted November 8, 2016 Well done on identifying the problem with the VVT input. Of your images above the upper image has the correct polarity on trigger one. If you want to upload an updated base-map and log file I'm happy to have a look and see if I can see any problems in the VVT control setup.Scott Quote Link to comment Share on other sites More sharing options...

Scott Posted November 8, 2016 Report Share Posted November 8, 2016 I think the control of the cam is not good because the ECU is reporting 'Error: extra pulses'. We need to determine why this is occurring. Have you re-done the cam angle test since you turned the Trig2:VVT to OFF?Scott Quote Link to comment Share on other sites More sharing options...
Piar Posted November 8, 2016 Author Report Share Posted November 8, 2016 of course i have done ityou can see that error is shows up during opening or closing of camwhen camshaft sitting stable in closed\open case - there is no errors at alli think that problem in vanos system it have low\no pressure in retard cameraso thats why we see errors Quote Link to comment Share on other sites More sharing options...
Scott Posted November 9, 2016 Report Share Posted November 9, 2016 You are probably correct. If you disconnect the solenoids does the 'Error: extra pulses' still occur?Scott Quote Link to comment Share on other sites More sharing options...
Piar Posted November 9, 2016 Author Report Share Posted November 9, 2016 Please take a look at logI have disconnected phisically solenoids and NO single error have occured vanost test with unplugged solenoids.llg Quote Link to comment Share on other sites More sharing options...
Scott Posted November 10, 2016 Report Share Posted November 10, 2016 Thanks for the log, I see you had the cam angle test enabled. This could also stop any errors occurring. If you run the system with the CAM Angle Test off and the solenoid disconnected doe the error counter stay at zero?Scott Quote Link to comment Share on other sites More sharing options...
Piar Posted November 10, 2016 Author Report Share Posted November 10, 2016 yesErors stay at zeroBut anyway with enabled cam angle test if something goes wrong i will receive different cam angles when i play with throttleSo today we age going to rebuild vanos system and will take a lookthis particular car havearoun 150 000 km mileage and problems with vanos have been guaranteed) Quote Link to comment Share on other sites More sharing options...
