A couple of weeks ago, i remembered that the R15 exists. It's basically like an R125 with a 150cc cylinder kit. I started to wonder if the electrics are the same.
I got this idea that i would get a 150cc kit AND an ECU for the R15 V2 (almost the same as the 2014-2018 R125). It would probably be easier to just get the R15 ECU that has a proper map already rather than a PCV that needs to be adjusted.

So, R15 V2 ECU in an R125 RE11. Is it possible?
Thanks.

R15 User here, I have custom ECU bought from Indonesia. For your question, you are probably right, remember the 2019 R15/R125 comes with a VVA feature and has a different ECU pin system. The R15 V2(2014-2016) is Fuel injected and the ECU should support your R125(given that your R125 is not VVA variant). Also, the new shape R125 that you guys got from 2019 was introduced at 2017 in Indonesia. And the R15 V2 production was called off at 2016. Make sure you get the years right. Also, if you own the 2019 version R125, then I could help you a lot. After I installed aftermarket ECU from Indonesia, I reached 161kmph(downhill) and might I remind you that I'm 106kgs in weight. The R15 2017 model is a fucking monster.

Thanks for the info! :D
My cylinder was in great shape so I decided not to change to a 150 kit, so there's no point in changing the ECU now.
