I took some time out of my busy unemployed schedule and sent the car to the "tuner" so they could sort out the over boost issue. I also told them it was running a little lean at the top end. ( Bill told me the previous map was running a bit lean ) So they "adjusted" the map and I did some logging this evening as its been raining most of the day and its nice and cool outside. Here the logs. and here the questions.... 1-What is the lambda % in block 001 ? What is it telling us? 2-Looking at lambda in block 031 - Would I be correct in saying the fueling is running a little rich now ? Block 032 shows -0.2 ( I cant find my old logs of the old map to compare this to ) 3-The N75 is still requesting max boost all the way through the rpm range. The boost is hitting 1.5bar then dies off to 1.2 at the higher rpm. What could be the cause of the boost dying off if N75 is requesting max boost? K04 just not up to it, tired turbo, boost creep? 4-Timing pull looks very high on 2 cylinders at high rpm. Should I be concerned or its that normal?
