| Az autó nagyon nehezen indul hidegen. Folyamatos haladáskor, ha elindult és nem vontatnak, akkor apró rángatásokkal jelzi, hogy vmi nem nagyon jó olyan nagyon. Mikor durván küldöm neki akkor szedi a lábát, de nem olyan nagyon. A fordulatszám, a gyújtás, az injektorok állása nem változik, mégis rángat. Van-e megoldás a problémára? |

---- Starts OK when warm, but startup problems when cold This can be a LOT of things. Describe your setup. Besides the basic things on IssueReports (firmware, config, wirings, etc...), also * measure DC voltage on VR input ** maybe pullup-resistor adjustment is needed (like a stronger pullup) ? * elaborate on injector size * compare starting pulsewidth to the runnig pulsewidth (at low RPM, near 100 kPa) ---- Also stumbles during cruise At high power it kinda works, but not perfect. RPM, ignition advance, injection pulsewidth stays constant, it still stumbles. This can be a few things. Describe your setup. Besides the basic things on IssueReports (firmware, config, wirings, etc...), also * make some logs and take note where you experience the problem * what is the current consumption of the ignition coils (at known RPM and actual dwell times) ? ** maybe dwell adjustment needed. Too high dwell can break the coils and or the power ignition outputs * do you know fuel pressure ? |
