Oil injection sounds like an accident waiting to happen. I'll end up putting straight gas in the wrong saw or mix gas in the oil injected one and smoke the place out.
The Temp sensor is inside the control unit on m-tronic models.
The file attached is form a clearing saw I work with. You can see the temp during data read out (marked red) from the dealer.
Yes the saw takes the temperature into consideration while running.Does the saw take into consideration the temperature while running?

Zitat from the introducion of the MS 441 C-M:
By monitoring the engine temperature and speed, the control unit continually checks the operating state of the chain saw and adjusts the fuel flow so that optimal engine power is always available.
So if it starts running hot it supplies more fuel? Aside from actually injecting fuel it sounds like it's doing all the control of fuel injection.
Can't wait to see what there are for sensors on this fuel injected saw.
I was under the impression that if you lean it out then it runs hotter then if it's rich. Why would you make the saw hit top rpm with less oil when it's running hot. Friction creates heat.
This. MTronic is far simple than people want to make it out to be. Creative Stihl marketing in the wording convinces most that it does a lot more that it actually does.All the Mtronic saws have a regular advance built into the coil, most newer saws do. However timing does not constantly change, it simply advances above idle rpm and retards at low rpm for ease of starting. The Mtronic system looks for nothing more than the best rpm under load, too lean rpm's drop, too rich rpm's drop. That's it! This is stated in many technical documents that have been on this site numerous times. The Husqvarna system has a temp sensor and TPS sensor, it's a more advanced system than the current Mtronic saws, when running correctly I prefer the Husqvarna system, as it seems to meeter fuel more precisely IMHO.
Creative is just a slight understatement. LOL
I have been wondering where they put the altimeter to tell the carb it was operating at 5000 feet above sea level.

What temperature is actually being measured and what are the tolerances for accuracy?
