Anyone tried the ECU re-mapping of the EU 120hp 2.0L skyactive engine with the data of the 165hp one? What's the easiest way to do it regarding SW and HW needed?

As far as North American market is concerned, Orange Virus tuning. They offer E-tuning where basically you log data with a laptop, and they send you calibrated ECU files based on what you submit until the tune is complete. There are other tuners, but honestly I don't hear anything about them other than them advertising their own services (i.e no customer feedback). I'm not familiar with EU tuners, might need to check a EU Mazda forum for that kind of feedback.

Thanks both of you guys for answers. I've read the whole main ECU tuning thread, but I would like to stay away from a custom tune.
I just meant to simply take a factory mapping from 165hp and uploading it to 120hp engine. That should be "trivial" with a piece of software, PC and some interfacing hardware. Also it should keep the emissions+consumption and all other parameters as they were set by Mazda for 165hp engine. Am I the only one interested in such a modification?
I have the european 165hp, and as far as I know, the mechanical differences between both cars are:
- i-eloop (not present in the 120hp version)
- Active front grill that closes itself at highway speeds for better aero performance (not present in the 120hp version)
- Different gear ratios (way taller in the 120hp version, for better mpg).
I know nothing about those camshaft differences, but still I wouldn't go for anything that is not a custom tune.

Yea ovtuning is a customized tune based on data sent in by you (from your ECU); your fuel (be consistent), the conditions in which you drive, your mods and how you drive that affect your logs. You don't want a blanket tune, it's not worth it. Your factory tune is a blanket tune already, and you want to improve it, why would you replace it with another blanket tune lol.
Blanket tune is not such a bad alternative if all I'm aiming for is to remove artificial restrictions set in the engine SW. It requires just one flash, therefore can be done in a couple of minutes and brings a boost of 45hp off the bat. Not so horrible, considering how much people usually get out of their tunes. I believe we all can agree that Mazda did a piece of fine engineering making those Skyactivs and the factory tune is imho very good.
Out of the three differences between 120hp and 165hp that CarlitosM3 mentioned, there is none really of the engine construction. Looking back, I'm not sorry that I didn't go for 165hp version, as I don't mind longer gears (I do tons of hwy driving), I don't need all the extra equipment that comes with the 165hp trim and after my previous 300hp car I don't even need that 45 extra hp. I'm just a tech geek who likes to learn and try new things and M3 is a nice toy to do so.
Any other source for the SW and HW information besides the OrangeVirus?
Very interesting topic dog, BBR will be releasing a DYI kit soon apparently, don't know if one can drop the calibration part of the ‘Super 170’ and just remove the throttle restriction.

Would it be possible to copy your map and share it?
Thx!

Hi,
I'm new to this forum here. My new, 2017 2.0L petrol, 120 HP, Mazda 3 is on it's way and by searching on the web came across this interesting thread.
I know custom tune is way better than 'off the shelf' tunes, however just wondering if anyone ever successfully attempted to load the 165 HP software to a 120 HP 2.0L ECU?
Thanks,
htomi

I had my 2014 Mazda 3 2.0L chip tuned last weekend, not the cheaper ones but a professional one who designed it specially for my car.

Nice! Is it a ecu tune only or a physical chiptune? I'm looking into this myself with my 120hp. The company I'm in touch with recommended a dyno run to get it done properly.

OK, so what exactly is a "physical chiptune"?

Removing the chip from the ECU, fiddling with it and putting it back. Seems like chipping and Ecu remapping are terms used interchangeably. I guess chipping is done mostly on older cars. I'm only aiming for a software tune.
