RyVan Posted March 7, 2021 Share Posted March 7, 2021 Hello! I am hoping someone could have a look at my data and maybe comment on what my car is doing. I have attached a csv file with 20min of driving data. If you think I should log other data points, please let me know! Car: 2008 Legacy GT, forged pistons, stage 2, 3" downpipe and catless Problems: surging with light engine load, loss of power and backfire, 100% throttle and high rpm When surging, the AF Correction 1 values are rapidly changing from negative to positive numbers. The backfiring happened once during logging, around data point 5380. What do you think is going on with this car? Thanks for your help!datalog8.csv Link to comment Share on other sites More sharing options...
