If it*s as bad as some of you guys claim, that would have been noticeable even in the snow.
Not really. You would lose traction in the snow far before this became apparent. Also, I didn't know it was being such a pud until I put it on the clock. You will note that the acceleration from 0-10 is the same as from 70-80 pretty much. This tells me that it's absolutely a tune issue. One that I will badger Mazda about until they tell me more.
Further, who's to say that it's NOT limiting based on tire slip? 310# is a decent amount of torque, especially at 2000rpm, and 300 treadware tires are certainly not something I expect to be worth anything at 13*F. My 370Z would have roasted even its' 275's or whatever in those temps in 1st gear and it didn't have near the torque. I'm very divided on how I feel about this, honestly. I plan on contacting Mazda until I get answers.
Looking and thinking more about this, I really think it's just eliminating tire spin before it happens. Facts:
-310tq @ 2000rpm
-300 treadware rated tires of 225 series
-cold AF outside
To test this theory, I need to punch it in the rain during a warm time, or rather, when water is on the road, and see how it reacts, if I get the same "slow 0-60" or if it spins. If it just goes slow AF, then I have my answer. Stoopid aggressive TC with great "logic", just prevents me from knowing things could be bad before they are. Not my thing, but it's fine.
