Rozsko Posted July 14, 2020 Report Share Posted July 14, 2020 Hello Gents again, New day, new question if you don't mind. https://1drv.ms/u/s!Ale4oyMCOgLThMpH8YTIGkT_LGav7A?e=DrnJvb In the log above I marked a section towards the end of the log where I was coasting in 2nd gear and above idle. The car was horribly jerking/bucking which you can clearly see from the oscillation of many logged parameters. Do you have any idea/suggestion on how to resolve this? Thanks, Béla Quote Link to comment Share on other sites More sharing options...
Adamw Posted July 14, 2020 Report Share Posted July 14, 2020 I suspect it is the fuel table needs flattening in that area, the logged fuel table value in that area is bouncing between 47-70%. Since the exhaust gas is moving through the system so slowly at low engine speeds you cant see the rich/lean cycling on the lambda. pvainola 1 Quote Link to comment Share on other sites More sharing options...

I gave it a try, and I can tell you it is better then before, but it needs a little more work. Hopefully I can make it smooth soon. Quote Link to comment Share on other sites More sharing options...
