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.

Yup, Mazdaedit he tailors the tune to your specific car based on the data you send back to him per successive tune. The handhelds are the same but they're not tailored to your car. You won't have to send data back and forth to him, and you can flash to different pre-made tunes easily. Because you're not sending data back to him, it's not as aggressive of a tune, since he wants to keep an extra layer of safety buffer. What the actual difference in power gains there are between Mazdaedit and handheld tunes are unclear. I wish he'd be a little more descriptive on his website. But i'd imagine something along the lines of a 93 octane tune file from the handheld will probably net the same gains as a 91 octane tune from the Mazdaedit.
It looks like I have the Mitsu ECU. I sent them an email to get some clarification on the handheld vs custom tuning options

Just received an email reply from Mat, apparently the support for the Mitsubishi ecu hand held tuners is real and not an April fool's joke, but it's not ready just quite yet, but soon. In regards to my question about tuning with the hand helds vs the tune kit, you are correct in that there's no back and forth logging with the hand held tuners, just flash and go. He did say though that there wasn't much difference between the 2 methods and that he's dynoed tuned them to be within 1-2 hp within each other. So for the average consumer I think the hand held tuners would be just fine and anyone looking for extra features or more in depth tuning can stick with the tune kit. Looks like Mitsubishi ecu owners will get to join the party soon

Alright! Excellent news! I wonder how he factors in the safety buffer if there is no back and forth data logging.
I imagine after tuning lots of Mazda 3's, he's got baseline tune parameters that he then modifies slightly for the custom tune. So he'd take that baseline & back it down a touch to give the average car a safety buffer for the hand held tune.
I have the mitsubishi ecu as well and am looking forward to the handheld unit :) My car is pretty much stock and only have a drop in filter, these tunes should work with a stock car as well right? It'll be my first time looking into tuning my car so kinda excited about this lol
Approximately how much is it for the tuning? TIA
Is OV a person or something else ? .. I'm in Dallas Texas does anyone know where I can get my 2014 M3 GTS tuned? TIA

Orange Virus Tunes
There is a website, look it up...........

I found out that OV has no affiliated, nor authorized shops within the U.S. that will do their tuning.
i've been seeing a couple of websites that have turbo kits for the new ND miata 2.0L. considering both engines are running high comp of 13:1, logically speaking, the application should be that of the same, straight into this 2.5??? with different results in gains...
I have done the tune and so may have some worthwhile feedback.

1. As ^ mentioned, the communication is rough. Also the documentation is terrible and conflicts with itself depending on which version of the doc you get. Through the whole process, I never really knew what I was getting. For example I asked for econ mode for standard driving and power mode for sport...still can't say if their is a total difference.

2. Do not bother if you're not going to increase your octane above 87. I did my tune for 89 and basically got drivability changes, but no real power increase. In other words I can tell the difference on how the car drives, however zero to 60 times for example did not really change. Also the calculated torque and HP were basically the same...... so to spend $600 for 87 gas is not worth it. For 89 is practically not worth it. For 91+ is where it would really pay off.
I think OVTuned might be having second thoughts with the Handheld tuner for the Mitsubishi ECU's. Last I checked in with Matt, he said there was an significant delay in them. I checked his website today and it's been entirely removed from the product line. Perhaps I should just go with the regular tuning route. Maybe i'll do a 91 octane tune just incase I run into a gas station around here that only sells 91 Octane, and to create a safety buffer.
I'm in the same boat (Mitsu ECU, 2.5 MT, but 2018). The ECU label says "PSAD". Any updates on the OV Mitsu handheld?

I don't think they're looking to support it anymore. Last I heard from Matt, it's not up to them because they're not the ones developing the software in order to access the Mitsu ECUs. Honestly I just bought the regular tuning package. You have the choice to upload an OTS tune through that, so no need to do back and forth logging.
More back to the initial topic and question, but there is another tuner out there for Skyactiv now!!

DRtuned Racing is up in Canada, and I've seen some pretty good results and heard really good things about their customer service and communication! They just posted some stuff about working with CorkSport testing their new Skyactiv header, and they made like 25whp over stock and a whole bunch of torque.

Would love to hear more about this. Anyone?

I can't post up any links yet, (Post count too low from simply lurking) BUT this should suffice for the time being.

Its entirely possible I may bump into these guys later this year during the Western Canadian Rally season. I plan to spectate more this year and possibly volunteer a bit as well. They actually had a post of a video on their FB page showing a rally start from a local RSX I know, very well developed car, something I wish I could buy.
I've heard some great things about DRtuned, and plan to use them for any tuning endeavors I might embark on. Would love to see someone else do it and give a review of their services firsthand on this forum though.
