Summary of change:
2005.11.25 When ever the engine has been turned on it has big problems, it does start but sounds like it mis-fire and it "jumps" when traying to accelerate just a little. It does not not matter if the car is warm or cold, or if it has been turned off for 1 minute or 1 hour, but the problem seems to stop just around when the Lambda-reading appears om the display or just before..? Could this bee related to some lambda-warmup thing that could disturbe the surroundings, or does the lambda controle work the same all the time? If the mixture is very rich, and it cannot ignite, O2 gets to the exhaust. Because of this, the WBO2 thinks it is lean, and ego-correction adds more fuel which does not help the issue. Make the EGO range very narrow, like * ego_rich_limit=1% * ego_lean_limit=5% * read TuningSession/VEtuning for more on the subject. ** My EGO is not activeted before CLT > 70c and it is there no matter what CLT-temperature. * is there some start-up enrichment that last so long (until lambda-reading appears or just before)? ** the afterstart enrichment decays to 0% from original (say +25%) in a configured number of cam-cycles (usually 255). While this is theoretically independent from the WBO2 warmup, it happens in the same appr. 25..30sec timeframe. Next step is to start documenting your setup. * don't forget about injectors (type, flowrate) * flyback setup * firmware and config * organize thematically (not chronologically), index on MembersPage/HansK This will make it possible for other to help you investigate the problem.
