alas, the trouble with my knowing just enough to be slightly dangerous.

The question you should be asking me is how do you hack the ECU.
If you're still lost see post #98.

Oh, do tell - how do you hack the ECU? What do you accomplish by doing so?

I'm waiting for someone to come out w/ a plug in tuner like they have for cars & trucks that let us remap the timing & fuel etc... not that timing is controllable through M-tronic, but you get the idear. Computers make it so easy to stretch the limits and dial out more power form the fuel system.

Good point. Hopefully the problems they had were just plating and not related. My concern has been that the piston cooling thingy is a sign that the design adds heat load, but as in previous conversations about it I sorta suspect it doesn't do much.

I was paying out rope, because these things are not "mapped" by the ECU. It simply does a lean out test, watches what the rpms do, and adjusts accordingly. The "mapping" of the basic fuel curve that the lean out test modifies as needed is done by the fact that it is still a carburetor so the mixture is approximately correct anyway. The ECU doesn't need to know much of anything about the engine, it only controls steady-state fuel mixture, and hacking it will allow you to do very little.
For example, apparently the problems of the 562 carbs have nothing to do with the AutoTune part, they're just typical carburetor issues.

I agree. Even if they did make a plug in tuner, theys very little that could be changed and the performance gain would be very low if any in my opinion.

If it exists it can be hacked. Moreover if it is mechanical, electronic and especially electromechanical, it will be hacked. If it is those things and we have one it has been hacked.
Performance 'gain' is always a trade off on some level whereupon something else has to give. Hopefully I'm talking to other mechanics here as there is no gain without loss. That's settled science. Thus 'gains' are amorphous. Paying out rope haha my ribs hurt. Refer to the law of conservation of energy.

Have anyone here tried to use the Autotune one on the Mthronic?
Someone on a UK saw forum said it could be done (but no updating of course)....

The plugs are different.
From what I've seen here.......those guys in the UK are ****ing nuts.

Yup. That guy, with all his various aliases, takes up a lot of room on my IGNORE list. Worth it though.
