I would not do that, besides the fact that there is practically no warranty, you can not return it easily. If you want to buy online, buy from a trustworthy store where you can easily contact them and return if needed.
This store offers a warranty and return option.
They all do that but when you want to return, things are not as you expected. You may end up spending more money on the return that the purchase price.
Do not buy important car parts from dodgy online Chinese websites.
You will regret it!
Anyway, in order for us to help , you need describe the problems/symptoms you are having with your car please.
Why are you trying to replace the ECU
An autoelectrician checked my car and noticed there is no combustion in two of the 4 cyclinders. He switched the coils back and forth and observed that all coils and spark plugs were working correctly but there was no power from 2 of the coils even though there was power detected in the wires leading to the two coils where no power was detected. I suspected there was an issue with the wiring harness connecting to the coils but he insists that it is an issue with the ECU. My car is a Hyundai accent 2012 1.4L sedan. What do you recommend?
Another mechanic mentioned that he wanted to take my ECU and try it on another car to confirm that my ECU is faulty? Does the other car used for the test also have my same ECU or it can have a different ECU but still be used to test mine?
If you can't find one in a local junkyard, as that's what I'd do, and a new part costs 3x or more,
You can order it in AliExpress, but make sure you have a good score, deal with returns/refunds ONLY using disputes.
Also verify wether you need programing (you probably do), and if so, make sure the seller can program it.
(Also did the electrician test the wiring? if he did I agree that it's probably an ECU assuming it's a Gamma MPi/GDi)
