For a while now I've wondered if the mtronic was trying to correct the saw back to maybe a "normal" programed into the mtronic range of performance. Thus my fear was that initial saw performance would be great after porting and would slow somewhat over time.
To test this I figured I would need a absolute never run coil and carb off a new saw. Figured I'd run my normal setup and then switch to a brand new coil and carb so the porting of the saw would be fresh to the mtronic and it wouldn't have time to bleed off any of the porting gains. I finally sold enough stuff to get a new 661. Pirated the carb and coil off it and here we go...
normal setup Tree monkey 661. 41" bar .404 RSLF new chain.
33.8 sec
Then I swapped to the brand new never run coil and carb and did reset and did a few cuts for the mtronic to learn.
34.0 sec ...I did a 2nd cut for good measure 33.5 sec - I pushed a little harder to make the saw cut faster on the 2nd cut rather than just my natural pressure.
my conclusion - it's not bleeding off performance. With the times being so close, I'd say it's amazing how fast the mtronic learned. Not to mention didn't fry my saw. (that was a concern I had)
A little background on why I did the reset - Stihl tech manuals say - when you change a coil or carb you need to do the "reset". I would have to agree. Saws just seem to run better when you do it.
