Can you be more specific about the ECU 1+4 ground connections ? where they meet, etc. checked: so I connected them directly to the battery but it made no difference.Increasing the factor (?) from A8 through to AF doesnt change anything and the fluctuation remains the same. The big problem is that the reading fluctuates between O2=6% and O2=16%, and it does it randomly.After turning on the heater, it takes more than 2minutes for the LCD to start displaying a reading for O2 that is not ?.?.In order to get the calibration factor i followed MembersPage/PhatBob/UserGuide.this is an assembled VEMS, it came with wbo2_pump_pw_zero=0圆8 and wbo2_nernstdc_target=0x85.If COP used, then wire up coils to IGBT's as follows (assuming 1-3-4-2 firing order): 1=>00 4=>01 3=>02 2=>03įor COP running in wastespark mode (1+4=>00 and 2+3=>01 paired up): Thanks for this suggestion, hence new req_fuel will be 3.2ms and 1.9ms for the two injector sizes respectively.įor wastespark setup (1+4=>00 and 2+3=>01 paired up): It's recommended to halve this req-fuel, so the max VE entries will be (instead of 100) around 200 (or even up to 255) for better precision. Proposed secondary trigger settings (not very well documented in the manual, but I might not end up using this trigger): Tooth relation Missing: 181 (irrelevant with multitooth advanced filter disabled).Tooth relation Normal: 122 (irrelevant with multitooth advanced filter disabled).Advanced filtering: Disabled ( NOT SURE WHAT THE FUNCTION OF THIS FILTER IS YET waiting for EricN's page to update?).

High current PWM driver for aquamist water injection high speed valve (HSV).RPM signal from ECU to instrument cluster to drive tachometer.Currently 440cc highZ injectors, but hopefully the VEMS will be able to idle the new lowZ 750cc injectors without problems.2-wire 4-ohm Bosch idle control valve, operating at around 140Hz.Now swapping to waste-spark using VAG coil from 2000 Golf 2.0-8V Single Bosch coil triggered by Bosch ignition module located just under the coil.GM open element air intake temperature sensor.Hall-effect type crank sensor on a 60-2 trigger wheel, see MembersPage/BasilDaham/CordobaSX/TriggerSetup.Mapped water injection with aquamist HSV solenoid.440cc/min highZ injectors, with 750cc/min lowZ planned for later.60 trim T3 Garrett with 0.63 AR turbine.
