Just curious, how many people are using the Automatic Mixture Correction (AMC) mode for mixture autotune, and how is it working out for them?

Looking for feedback.....

Has anyone tried this?

Bruce, I ran it for a couple of weeks on a map that was already well tweaked by MT's autotune. It made occasional, small changes, much like MT does. No drama, no surprises. Car currently down getting reconfigured to use 2 MS boxes - 1 v3,MS1-Extra box doing rotary ignition, tach out from this one firing a v2.2, MS2 box taking care of hires fueling business. New exhaust and cold air intake as well are being fitted so will be putting AMC in charge of fixing whatever VE changes this produces. Hate those 130F MATs....

I have it turned on in my B2, the VE was already tuned good so not much of a change, I was going to purposely change some values around cruise and see if it eventually changed them back, but I haven't got around to it.

I have not seen any adverse effects of having it turned on for extended periods.

AMC is one of those things where if it works you should not notice anything out of the ordinary (that is after its tuned). If you get a change go ahead and change some of the VE values at cruise to see if AMC captures them and changes them back.

I just want to see if it does a good job at rejecting rogue data points. If a outlier gets in I would assume it would get corrected out pretty quickly.

Thanks for the testing!

I'll do some testing on it tomorrow, as I want to connect a knock sensor and test one of my new boards with the knock circuit on it.

I saw this AMC on my Megaveiw and couldn't figure out what it was. I tryed searching and it just said it was the auto mix correction or something, but no explaination of how it works.

I am assuming that embedded code2.3x doens't use this since I have seen nothing in MT and changing the numbers on the MV box has resulted in no changes in preformance...but those changes where at idle too, so it porblaby had no effect since auto tune was not in the rpm range.

I wanted to give this a try but it is not showing up in MT under settings. I am running MSII on a v3 board running 2.36 code and MT 2.25.

Thanks. Brian

Brian,

AMC (automatic mixture control) is only in the 2.5 and higher code (see the beta forum).

The latest of version of this will soon be publically released, I believe. For more on AMC, see: http://www.megamanual.com/ms2/amc.htm

Lance.

So even though I have access to change the AMC with the megaveiwer, is still won't do anything since I'm rocking the 2.34?
