So, it’s worth having a Tech 2 clone?
It’s a customer review. Read it and get the truth.
Received the GM Tech 2 clone today. Five days from China, not bad for free shipping. Checked it out and everything is working fine except the AC-to-12VDC power adapter (dead). No problem, because I can get one anywhere for $5. In short, that is a nice piece of equipment to have, very nice!
Aside from working beautifully with OBD2, the tech2 is the scanner for GM OBD1 to use. with the right software (plug in chips like nintendo cartridges) it’ll do some daewoo/suzuki, GM medium duty (meaning bigger than 3500 using non automotive OBD2 standards), and other in the GMdistant family tree too.
In addition to generic codes (P0000-P0999) It’ll do all the proprietary GM codes (P1xxx), actuators, and systems. you can also view fuel trims, emissions readyness (beyond a green LED for all OK) and It’ll talk to ALL the modules rather than just the ECM (and if you get into the $250+scanners, ABS) like BCM, SIR, entertainment, EVERYTHING on a GM. At school I used one with a 91+ cartridge on my 87 S10, so going back further is hit or miss but possible.
To adjust shift points and fuel consumption and Speedo, forget it.
The TECH2 can’t do any sort of modding/tuning, only upload GM flashes. At least with legitimate software. I’m sure someone has custom software to do it but there are easier ways nowadays.
Is it worth if you just want to read/clear codes on your own car once in a while, heck no. If you’re doing a lot of work on GMs or want to get a lot more in depth with your car, it’s worth the money.
No comment on China knockoff quality, I mean a working tech2, Chinese made or not.
See my Gm tech2 scan tool. It’s working well.
