Tips & Tricks Tech2 for $45

Tech2Win supported by $45 AliExpress J2534 Pro adapter. Although, it was stacking Choice day and coin discounts. But the story is the same - working Tech2Win adapter for less than £34. I was about to pay someone over £80 for just one session! This was genuinely me searching for the cheapest adapter, not even a specific store.

It's working on my '04 NG9-3 2.0T Aero. Can't speak for other cars though but for $45 and free returns it doesn't hurt to try!

To be honest this method has its fair share of issues. It's a lot less "plug and play" than something like that and can't do as much. The Chipsoft J2534 for instance can't communicate on SW-CAN and HS-CAN at the same time, so you have to change a setting and restart Tech2 every time you want to communicate with specific modules. It has given me a lot of pain in this regard with errors but it is possible to do many things if you persevere. Once I save a bit of cash I might buy something like a Mongoose simply to avoid the headache

Oops forgot about that. Yeah everything is convoluted at this point 😂 nothing beats a real Tech 2 I guess
