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?

You can't really remove the chip from the ecu, it doesn't have one.:dunno: The only way to get a decent tune that works is remapping. Doing in conjunction with a dyno is the best way to go.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.

That's great. Settles my confusion. Thank you.
I was surprised to find out the same, after lots of reading about tuning options for my Skyactiv 120. It’s rated as 118 HP, but they typically put out 135 to 140 HP. A mild OBD2 tuning gives about 10% gain, so that makes around 150 HP without losing your warranty. Quite impressive.

Are you sure about the warranty?
I've asked the dealer about the tune, however couldn't get a definitive answer....
I'm toying with the idea to purchase the off the shelf tune from BBR GTI.
As far as I'm ware an ECU flash will leave some 'footprints' which can be easily discovered by the dealership and as such may lead to losing the manufacturer warranty.
Positive. In The Netherlands that is. Some official dealers (not just Mazda) even sell these OBD2 modules. They give some torque gain, but nothing sensational. All they do is fiddle with a few sensor values to fool the ECU, within safe margins.

Would you mind sharing some links if possible?
this is exactly the reason im going to chip tune my 3 months old mazda!Any good tuner can do for you .
Copy maps is not good idea
Here is dyno sheet of chiptuning of 120 HP version to almost 180 . Mazda 3 skyactiv-g 2.0

you see the stock BHP curve where the engine cuts off at 4400 rpm.. they did that deliberately to reduce emissions in EU and sell it at a lower price to be competitive -- there is no BHP curve that cuts off like that ... the car feels like its at the beggining of a great acceleration and right there it simply stops --- it doesnt feel natural.
its time to remap..
Hi apocolyps911..,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.

Can you tell me the results/gains of your tuning job and if you are happy with it please.., considering the same on my 2014 2.0 120 but would like some feedback off someone who has actually had it done.
Thanks..!

Reviving this thread. I AM A UK 2015 MAZDA3 SKYACTIV 2.0 120BHP OWNER. Considering this. Has anyone done this with success or got any feedback. My current insurers will only.cover a 10% bhp rise.

There seem to be two options in the UK. The more expensive ÂŁ595 option from bbr. BBR Mazda SkyActiv StarChip Remap | BBR GTi
http://www.bbrgti.com/product/bbr-mazda-skyactiv-starchip-remap
It’s the work of little more than a Starchip ECU upgrade with revised fuel and ignition calibration, and removal of the electronic throttle restriction. That simplicity keeps the price down to £598.80 (including VAT).
Or there is the option from quantum tuning for ÂŁ250 where someone just visits you house an the ecu is updated from 120 to 180hp.
Mazda 3 - ECU Remapping and Programming | DPF Solution | Chip Tuning | EGR Solution
https://www.quantumtuning.co.uk/car-remap-tuning-remapping.aspx?Make=Mazda&Range=3
Now I don’t really know the difference between the two company’s. I am guessing they both just update the ecu though the second company do not use a dyno ...but would the need to anyhow ?

Did someone manage to get a stock 165bhp original ecu file?

I just bought a Mazda3 2017 2.0 and I'm still thinking about this upgrade. For free I would do it instantly by myself, but as I know there is no homemade. For example in Hungary, the chip tuning costs 300-350€.

Based on the result there won't be much more torque in the normal range (+10/+15), only above 4500 where the 120HP settings limit the engine (in reality it is 132HP).
From another point of view: you don't even notice it during daily use, At least I don't usually rev the engine up to 5000. It's also a good thing, that the basic 2.0 120hp engine has technically the same stats as a 165hp engine (under 4500rpm).

Do you know if there is still a tuner in DK, that fiddles with these models?There are no hardware requirements, as the engines are the same between the two models. Mazda simply added a software throttle limitation to the 120 hp version at the top-end which can be removed by a tune

I went to a tuner a few years algo and upgraded my 120hp to 182hp. 145.000 kms right now, and everthing is still working like a charm.I just bought a Mazda3 2017 2.0 and I'm still thinking about this upgrade.

you did it in Hungary or?
I am seeing a lot of “offers” for remapping all across Europe, I am afraid of screwing up 🤣

No I did not, I did not feel I need it, but the remapping is pretty safe (not a DIY stuff)
