    Changing DAM?

    When I was going to summit point yesterday, I noticed my DAM go from 1 to .9 then eventually .8. At first I thought I had a hiccup in my tune. Then on the way back home, the closer I got to home the DAM slowly increased to .9 then back to 1. Why could that be? I live in Baltimore and summit point was in WV I believe. Could it be the air?

    So. If u understood correctly, that was the ecu's way of switching or adjusting to the new environment?

    The car felt the need to pull timing globally at some point, and then slowly determined it was safe to go back to full advance.

    It was "safe" but you should avoid it if possible.

    How many tanks of gas were involved - one tank on which it went down and a new tank on which it went up?

    It could have been the elevation change, but the stock tune shouldn't have any trouble accommodating that.

    Edit - it doesn't look any different in elevation even, so no, it was not the air.

    Well I didn't do a wot pull because I was unsure. The changes were all within the same tank of gas. I was thinking it was the elevation change. Also, I'm not running the stock tune.

    I'd log and take the data back to them and demand a retune. A custom tune, in my opinion, should be safe and definitely not drop the DAM/IAM.

    It will drop if you get questionable gas. See if it comes back over the next few tanks. I wouldn't want it de-tuned over one event.

    Thing is he said it was over the same tank.... I guess I am jumping the gun a bit.

    Just monitor it for the next few tanks and see what happens.

    Yeah, IDK. The elevation isn't really any different. It could have just been heat soaked too. If the gas is marginal it could run up and down. Otherwise they should definitely fix it.

    This is an old thread, but after this event I got another map. Seemed to work ok until Saturday (roughly 1000 miles using the map) & once again my car pulled timing & my DAM was at .1, but this was after a pull. I pulled a log & the guy from NASIOC (Clark) said my car has a cracked ringland from how my car pulls timing. Could this be true? Also what are the symptoms of a cracked ringland?

    Blue smoke and low compression would be a sign of a cracked ringland..
