yeah the VE analyzer is sick nasty. just another reason megaquirt is so damn awesome. it amazing enough to have a $200 full standalone, and then it will basically tune itself just blows your mind.

Too bad its so unreliable and never works. :jerkit:

I laugh at people when they tell me how unreliable they "heard" megasquirt is. Then tell them maybe the people they're talking to are retards. :hustler:

MLV == teh Shizzle. No other way.

+1 i was running v2.2 (pre 3.0 for the OGs) when the megasquirt trend just started about 2-3 years ago. it really is the best thing that has came to the car/bike performance world in a LONG time. and everyone still doubts it, if they have even heard of it :bang:

The only problem I had with MLV and VE analyzer was that it did not seem to want to converge on a solution. That is, each subsequent log and VE tune would go leaner-richer-leaner-richer, and just oscillate back and forth. After raising the ease from normal, to hard, to very hard, this problem seems to have been minimized.

You have to be close though before you go to the very hard setting because the VE adjustments become very small at that point, like 1-2 points, even if the VE is way off. At least that has all been my experience.

People are so ignorant. I built mine in 2003 before V3 / MSII was even a concept. Its been an interesting road and I've had some problems, but all were because of my own mistakes. During the approx 7.5 months I've had MS Installed on my miata theres only been one reliability problem which was fixed by reflashing the firmware. It still blows my mind how simple the whole thing really was -- Everything from the build, installing it into the car, configuring, and tuning.. What a great learning experience it was, too! :cool:

In other words, the tune was doing the exact same thing that the mixture does on a stock car normally, yes?

(waiting for it to settle)


And that's exactly why that variable is there.

Ever painted a car? Or painted anything that requires sanding?

When you first start out, you have the MS set with large EGO authority and short step times, and you have MLV's analyzer set to easy. This ensures that you can quickly get the table roughed in. That's the 500 grit stage- it's making big changes quickly.

As you progress, you start to slow the EGO feedback, and set MLV to Normal. 1000 grit- starting to take the rough edges off the map. You'll probably start learning to properly hand-tune the cells around idle at this point.

As the map starts to really fall into place, you reduce EGO authority and switch MLV to Hard. 1500 grit- now the map is getting smooth, you'll be filling in those cells at the edges of the map that never get touched.

And lastly, you'll spend some time at MLV Very Hard, just to see what it does- cells will be going up a point or two one day, down a point or two the next. At this point, you can whip out the 2000 grit and give it a nice hand-polish. (ie: tweak the last few out-of-bounds cells by hand).
