DAM inquiry
So ive been on Stage 2 ECBS OTS map for about 2 weeks and everything has been great . There have been small instance of FKLC and Feedback but nothing out of the ordinary. Today my DAM dropped to 9 and I feel like I can almost peg it to going up a decent hill in 5th and being on the throttle. Does this make any sense? How long would I drove another 30 mins and it remained at 9. I reflash the map later on and it's been to 16, but now blipped to 15 even after like 40 more miles. How long does it take for DAM to restablish itself at 16. Car is running fine and all my readings on AP look fine. Should I just be continuing to drive and let it get there?

this is a good article about DAM and how knock can change DAM values: http://www.cobbtuning.com/subaru-kno...logic-changes/
if conditions are good, the car will learn appropriately and go back to 16. It is possible you have filled up with a bad tank of gas, which can cause knock/lower DAM. Also, make sure the mods on your car match EXACTLY the map notes. if even one small item is out of place, you'll need a different map or a protune if no OTS map exists. |

this is exactly whats happening to a friends car, except with a fresh pro tune. the car was mint for a few weeks until it started to get super hot out. DAM drops to 9 even after resets, really no knock occurring. I have to take a guess that its a combination of possibly bad gas and the heat, its been 90 degrees everyday for the past few weeks.

I'm in WI on 91oct. It's still pegged at 15 and was told that if it gets set to an odd number it won't go back to 16 on its own. I need to reflash. I'm positive it happened while being on the gas going up a hill in 5th when I should've shifted. It has been humid here but car is driving fine now at 15. I will be changing plugs and timing belt and getting a tune from Eric at Tp.

what would a reflash accomplish that a reset would not? nothing that i can tell. get a custom tune. do you not have access to 93 out there? if your DAM wants to drop, i would NOT keep resetting it to a higher number. your ecu is dropping it for a reason.

log looks good to me. i think you're worried about nothing. the learning is positive in that log, so you're on your way back to a higher dam unless something else happens. (someone please correct me if i'm wrong, i'm still learning here also!).

Here is another article from Cobb to clarify that the DAM does learn back up to max value if the car is running its best: https://cobbtuning.zendesk.com/hc/en...ck-on-a-Subaru Quote:
