I'm creating this thread primarily because an issue was reported in the CX-5 subforum regarding power loss in the turbo 2.5 engine in cold (20f and below) weather, but I figure this could also be a fun brag thread for those with other Mazda models.
Here are some TorquePro screenshots from a few runs I just did with my 2018 Mazda CX-9 Signature (2.5T AWD). Temps were hovering around 34f (1c). I plan to do a couple more runs when temps hit 10f (-12c) to see if my CX-9 also experiences power loss in colder temps. The goal is to determine whether or not this is a tuning quirk that Mazda implemented to protect the turbocharged engine.
All of these runs were done on the same stretch of dry, clean roadway. OEM 20s with Blizzak DM-V2 tires. Acceleration was from a dead stop (no "brake boosting" or "torque braking"), pressing the pedal straight to the floor as fast as I could and engaging the kickdown switch. Heater was on for all runs because I forgot to turn it off (hand)
First run was with the engine cold (blue temp indicator still on the dash).
Second run was with the engine warm.
Third run was with the engine warm, and my Sprint Booster set to "Race 7".
EDIT: Sorry for the large sizes, I'll resize them in future posts.
