Mazda3 2.5 Skyactiv tuning options

Hi there,

I recently purchased a used 2015 Mazda3 2.5 with the 6spd manual. I'm itching to get it tuned but want to be sure of all my options and what i'm getting myself into before I pull the trigger. I've been reading a lot about OVTune, as he seems to be the main guy for our car. But are there any other tuning options out there? I understand there's a whole process of sending WOT logs back and forth. And then there are handheld OTS tunes available. What's out there, and what's the consensus on them? Thanks.

I actually bought this car knowing I would get it tuned lol. My question is, what do you actually get with the tune? Is it possible to have two different tunes (one for 87 octane, another for 93 octane for example) and easily switch back and forth between them on some piece of hardware? And i noticed they also offer handheld units, but not sure if it's offered for our 3rd gen Mazda3's. Which did you buy?
Handheld units are more for OTS tunes and afaik they werent offered on our cars. It is possible to get to different gas trims tuned on however I believe that will be 2x the cost. Each tuning order is specific to a trim of gas, meaning if you want to be tuned on 91, that's what you're paying for.

I personally got tuned on 91, but asked for normal mode to be tuned for fuel economy, and sport mode to be as balls to the wall as possible.
How do you switch between tunes though? Do you have to plug in your laptop into the OBDII and do it that way? Also, i wonder if it's more cost effective, in terms of fuel costs, to do a single octane tune with a fuel economy mode, rather than 87/93 octane tune?
Laptop into OBDII every time.

Sure, you can save some money (about 20 cents per gallon where I live) from using 87 instead of 91 or even more for not using 93, but the gains are going to be far less using 87.
Nice! Let us know what your experience with it once you get it. I'm kind of debating right now whether i should get the handheld or the custom tune. Does anyone know if the custom tune allows me to edit the ECU tune myself if i choose? Or is that a different package? I figure if i can learn a little something about tuning by getting the custom tune, I should consider that.
I'm not entirely sure if we can edit our own data however if you wanted to just learn more about the process and your car, the custom tuning software (MazdaEdit) is cool to play around with and look at all the car's variables such as different temperatures. You can also record and analyze data logs whenever you wanted whereas with the handheld tuner, I do not believe you can do this or even view temperature variables within it (not sure about the latter).
