When the car runs at ca.4000 rpm or boost at low rpm it starts to misfire. I have connected a led diode and can see some change in the light when it happens. Dwell is best with 1 ms if I add more the problem get worse. MatinFrank had the same problem and never got it fixt, so anyone has any suggestion?? ---- '''tiny little spark at the plug "sometimes "''' * I have made a mix connection so i can switch be twin the org. Bosch ecu = and VEMS ** mixed connections are very hard to get right and usually cause a lot of problems. * RPM, injection and the rest seams to be ok. Tried to adjust dwell timing but no luck ** what dwell values are you using ? '''Coil specs''' from a standard Ford Fiesta wasted spark (edis). Should work well. Measured the coil: * Pin 1-2 = 0,5 ohm (pin1 is for cyl 1-4) * Pin 2-3 = 0,5 ohm (pin3 is for cyl 2-3) * Pin1-3 = 1,0 ohm (this is the sum of 0.5 + 0.5 Ohm) * '''secondary winding resistance=''' ... kOhm '''Please note that according to above measurements pin2 is the common +supply of the coil'''. On pin2 you want a switched +12V connected through a 10A fuse. * does the "tiny spark happens on cyl1,4 or cyl2,3 ? **There is a tiny spark on both the coils 1-4 2-3 * did you check the HV wires ? **Yes .Also triad to ignite with out the wire * try to make new connections to the coil. Make sure there is absolutely nothing else connected that should not be! (like alien ECU outputs). **The output is tested with a light diode and working well * measure coil supply current in 10A or 20A DC current mode (and take note of RPM and dwell values). **Triad to connect direct to my lab power plant and the current is 4 amp voltage drop down to 9-10 V * in any case, you need to document firmware version and config and link to it from the question !!! I have triad to Messer the resistance of the secondary side of the coil from top of the plug to earth but no resistance The dwell settings 14V is 1,5-3 ms also triad to connect the coil direct to 12v pin 1-2 and 2-3 still no spark so maybe the coil is damage http://www.vems.hu/files/PeterJensen/ignition/coil.jpg I have a question about Wbo2 calibration Is not possible calibrate the Wbo2 to 20,9 . When I change to ff = 255 Hex (wbo2_calibration=FF) the results become afr 20,1 and it not possible to go any higher. Does anyone know what to be the problem?? * it's definitely '''pump_pid misconfiguration''', the nernst cannot reach 4.45V (or more exaclty pump- + 0.45V) ** wbo2_pump_pid_ki=01 is surely wrong (where is the 01 value from?) try 0x20.. 0x40 or even 0x80 if you decrease wbo2_pump_pid_ilimit to appr 40..80) * btw, measure RCal (resistance between sensor pin2 and pin6) **Thanks Marcell wbo2_pump_pid_ki=01 changes to 64 Hex all clear now Best Regards Peter wbo2_warmup_ramp=A0 wbo2_warmup_target=FF wbo2_abs_limit=E4 wbo2_limit_maxt=A0 wbo2_fallback=60 wbo2_retry_t=06 wbo2_edgetime_corr=BA wbo2_edgetime_min=50 wbo2_ri_target=C1 wbo2_nernstdc_target=8F wbo2_pump_pw_zero=64 wbo2_calibration=FF#= 20,1 afr wbo2_heater_pid_kp=46 wbo2_heater_pid_ki=10 wbo2_heater_pid_kd=1A wbo2_heater_pid_ilimit=A0 wbo2_pump_pid_kp=40 wbo2_pump_pid_ki=01 wbo2_pump_pid_kd=00 wbo2_pump_pid_ilimit=E0 wbo2_ri_confidence_scale=80 Optional: Add document to category: Wiki formatting: * is Bullet list ** Bullet list subentry ...
