None of your log is useful. YouTube Wrx Cobb Datalog How to. You need to be in 3rd gear, just above 2k rpm and go WOT till redline. And where date to do so. Watch the video though and others. Great learning tools.

Touch the gas pedal only very slightly when you're under 2000 RPM at 3+ gear!

You don't have any boost/torque there.

Better yet, stay above 2000 RPM in 3+ gear all the time unless you're cruising.

You want to put the car under some load (if you can do safely) so we can see how it reacts. Check out our data logging video below.

You have some knock in the first log - I would reflash the 91 octane map. One of your A/F Learning 1 trims in the very low airflow range is borderline high (+7%) - I would keep an eye on that to see if it gets worse there (or in any range). You may have an intake tract leak.

Thanks ! I switched to the stage 1 91 octane map and i did 3 more datalogs , i tried my best to do it safely and without getting caught speeding .and i also changed to a new gas station.

The first two logs look good. The last log has a single count of feedback knock correction. I would continue driving the car on the 91 map and see where your fuel trims end up (through a tank of gas). They were cleared when you reflashed the map, so they will take some time to populate.

Change your map to the 91oct map. You're getting fine knock learn in the high rpm's which isn't good. Post logs of the 91oct map.

cmiovino · 09-17-2012, 11:47 AM

I literally just swapped over to the 91 oct map after experiencing some FKL in the 2-3k range. Mine took effect immediately after driving and I had no knock. I'll log again after a week of driving, but in my opinion, what you were experiencing with the 93 oct map should have gone away after switching.

ricky0418 · 09-17-2012, 12:26 PM

I don't really know what to do at this point :/ .How bad is it? Would a protune fix this ?

bacalhau16 · 09-18-2012, 03:34 AM

its not that bad. You're DAM is still at 1 which is good. This is basically saying you are on the optimal timing map.

Like said before, continue to get through this tank of gas, fill up with the best gas in town and log again.
