About me
I didn’t know anything about cars and had bad luck trying to find a good mechanic.
Once I decided to buy cheap OBD2 scanner for fun and realized one of my mechanics is completely clueless about cars (I literally found issue with my car he couldn’t solve with simple scanner and fixed it myself).
Then second mechanic tried to scam me replacing part I didn’t even had in my car.
I got hooked to OBD2 scanners and I have been testing them since 2022 while also learning car diagnostics, car cybersecurity and ethical car hacking – that’s why the name iamcarhacker.
On this website I am sharing my knowledge, tests and recommendations for best OBD2 scanners.
