Default Has anyone put a standalone in a skyactiv car yet?

I googled this as a thought experiment for potential ND ownership or for my 2.5 mazda3. I couldn't find anything online- has anyone seen a skyactiv engine tuned for better gas? Has anyone seen a race application of a skyactive-g engine that made more power than stock on better gas?

I seriously doubt ur gonna tune that skyactiv engine better than the mazda engineers, you could probably make it faster and worse on gas but not better. google hypermileage if you want to learn a few tricks to squeeze a extra few mpgs out but dont expect miracles. An example of one of those tricks is driving more gently, and perhaps getting narrower tires.

I am not asking about mileage. By tuning for better gas I mean tuning for gas that isn't 87 octane.

Mods of this sort are more likely to come from a modded stock ECU.

Typical Mnet response...

EcuTek or similar tools will be the first option to get some power focused tuning for higher octane fuel.
But it will be some witchcraft in the beginning and some tuners will find more power than others (and some will destroy engines without understanding why).

There seems to be more ways to mess up with a SkyActiv engine than a BP, so I would assume the threshold for a full standalone would be higher (and I assume the OEM ECU is very capable, if unlocked).

Yeah pretty sure the stock ecu's are unlocked. Now how easy it is to use mazda edit is another question all together. I was looking to help someone with their 3 and found all of one person who wasnt a tuning shop using the software and it looked like its still in its infancy with a lot of "heres a table with some very confusing name that we're not sure what it does exactly but it seems to change fueling kind of".
