Summary of change:
2005.11.25 When ever the engine has been turned on it has problems, it sounds like it mis-fire and it "jumps" when traying to accelerate just a little (high "ve"). It does 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 fade away the last 10 sek. before the Lambda-reading appears om the display/MT? *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. **I belive it is the mixture that is wrong, but by the time the lambda-readings appears the problem is gone, so I got no idé how mixture is but it is not the ego-correction. But I'll try to adjust a little on the afterstart settings settings and see what happens, maby mount a NBo2. Is it posible to "pre-heat" the WBo2 so you can get readings right when the engine start? *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. -------------- http://www.vems.hu/files/HansK/Config_24-2.txt --------------- MembersPage/HansK
