As a designer of electronic controls, I have dealt with the issues of creating digital controls to replace mechanical controls and logic. Every year the components to do this has gotten more robust, making the job easier. Even for large company's like Stihl this can be a challenge. Like in your car and many other products we now take for granted, it will add a level of performance that can't be done any other way.
Agreed, our saw engines don't need to do anything more than start easily, idle, accelerate to high speed and produce a lot of power, efficiently and reliably . If not now, someday M tronics should become a reliable product that does all of things our saw does now, even better. When will we know they believe there there? When they build only M tronics versions. They maybe there now, or not, but from what I read, they need to get there reputation back. Until then M tronics saws are beta test sites.
