Before posting up your datalog, make sure you are prepared to also include additional information about your car. Without this data, it is nearly impossible for someone to give good feedback on the logs.
1. Post a short, relevant log with necessary logged parameters (see
FAQ). Make sure you trim any non-relevant portions of the log and don't accidently trim the column headers out. If it is a WOT log, try to cover as wide a RPM range as possible such as 2000-2500rpm to redline.
2. Post a copy of the map used to generate log and what changes it has in it. Without it, trying to analyze a log is not much more than guessing!
3. Post all engine modifications.
4. Post the year and model (WRX, STi, LGT, FXT, etc) of your car.
5. Post the fuel being used, your location and weather conditions.
6. Tell us what YOU think. If you have no idea, please go read the FAQs, do some research and review other threads first.
If you don't post all of this information, you be much less likely to receive constructive feedback on your logs.
Thanks and happy tuning!
