Air Fuel Learning (Long Term Fuel Trim?)
Over the past few months I have been tunning my car using the Openecu tools. After flashing a new tune everything goes just fine and then after a few days the car starts pulling timming. It was suggest by someone that I take a look at the Air/Fuel learning, which from what I understand should be -/+ 5%, anything more requires attention (Correct me if I'm miss informed). My vaules range up to +7%.
I suppose my question is, does this require attention and if it does, where should I look for a problem. I've search, and I really can't find much related to Air/Fuel Learning or Long Term Fuel Trim. At this point I'm rdy to rip my hair out, everytime the car is running good (or great), it only takes a few days for it to be ruined. Any ideas about how to track down this problem would be a great help. Thanks 04 WRX Uppipe Downpipe Stock image (with OL/CL fixes). If any other info is needed, logs ect, let me know and they can easily be provided. |
