Summary of change:
VEMS Round with Motronic 7.1 VEMS Round using the following input: - WBO2 - EGT - Analog 1 --> 10 bar oil pressure sensor - Analog 2 --> 400kPa VEMS Map sensor * Apparently there is no way to display *BOTH* analog outputs on the display. I would like to see both boost and oil pressure on the slots. ** '''Very''' outdated information. If you need to display both analog inputs on the round display at the same time, '''just use the latest round fw''' (and in VT Preferences, update ini files from web, of course) and [http://vems.hu/vt/help/round/round_dialogs.html read VT help]. Support for ANALOG2 on display was added a long time ago. ** Latest nightly VT only supports using ANALOG2 in Display Mode, Main Display Settings do not have ANALOG2 at all and if we configure ANALOG2 in display mode, the main display settings show an empty string in the dropdown. Outputs: - PWM0 -> reference RPM drive warning led for shiftlight - PWM4 -> reference RPM drive "shift-now" led for shiftlight * Set both PWM0 and PWM4 for rpm target, fill the targets for shift warning and shift now, set PWM0/4 KP to high value 255, that should make the PWM0/4 channels work in shift light like manner. Both PWMs should reference RPM and start sending PWM signal to the respective leds when reached the configured RPM. Either needs a new target method for both PWM outputs or a hackish way is to configure an unreachable EGT or lambda target. Sounds like a crap solution. * Linear wideband output is connected to Motronic 7.1 for data-logging. (This Motronic ECU is dual-narrowband with dual EGTs for mixture preparation.) ** vout_conf=5 and conversion configured in Motronic as advertised on the AfreshTiny/VoltageOutput page: 0V -> 10 AFR 5V -> 20 AFR To calculate the factor, we first must remove the offset. We do this by subtracting the value at 0v from the value at 5v. 20-10=10 This number is the value at 5v without the offset applied. To get the value per voltage we just divide this by 5 (volts). 10/5=2 Our factor is 2 and the offset (value at 0v) is 10. Now we just apply the factor for the particular RAM variable that we are working with in ME7. uushk_w voltage factor is 0.004883, so we multiply this by the voltage to AFR factor that we calculated for our new input. 0.004883*2=0.009766 ME7Logger applies a negative offset, so in order to use a positive offset we just need to flip the sign. The values that we have been working with are AFR, therefore to convert our input to AFR: Factor : 0.009766 Offset : -10 - RPM input is coming from the Motronic RPM signal (instrument cluster) '''Q''': Can this even be configured or do we need a crank signal?! If that's the case the documentation (Help) should be change to state something other than "RPM Signal". '''A''': Yes RPM signal from dash is fully supported, [http://vems.hu/vt/help/round/round_rpm_input_settings.html more info in VT help Rpm Input], example for 4cyl: rpm_toothcount=02 for a 4 cyl 2 events per rotation '''Q''': Any pointers on configuring it for 6 cyl 4stroke V6 engine? Setting it to 60-2 wheel does not work obviously. Thanks '''A''': For 6cyl 4 stroke, 6 rpm events per cam rotation, 3 per crank rotation the correct rpm_toothcount=03 '''Q''': With above settings it is not working properly still, vemslog available at: http://nerd.hu/r2.1_4513-2015.04.02-12.42.18.vemslog
