This post starts with a question “These “GM TECH 2” can do things HPTuners cant right? Things like override TPMS, open ABS valves for bleeding, etc.
So to have a complete DIY station I would need both; right?”
The answer is
” HPT can only work with ECM and TCM . Tech 2 can work with ABS, BCM, etc. But, Tech 2 can only change/do stuff GM intended where HPT can change all kinds of tables GM wouldn’t want us messing with. None of them mess with TPMS. Only way to disable TPMS is the LG box, or rig up sealed tube at set pressure and put the TPMS sensors in it. So both have pluses/minuses depending on what you want to do.”
Got mine GM TECH2 clone from cardiagtool.co.uk, I got the SP23-B3. Came with no carton box, took 1 week.
$339 for a brand new tech2 with a CANDI module all the cables and adapters and case is great.
GM TECH2 clone reads everything a genuine one does. Heck, it’s probably made in the same factory as a genuine one with a different sticker on it. Here I post some GM TECH2 can work on what models:
Tip: You have to specify GM English when you order the unit. There are a lot of other cards for different languages Saab, Holden, etc.
- Hooked it up to test engine, ABS, transmission etc, stored DTCs, Freeze Frame, live data all the test result were displayed on the large, easy –to-read backlit screen. It helped to carry out accurate and stable diagnostic function.
– To retrofit tcs and marry a non divorced cd changer.
– Used it to pinpoint bad air bag sensors, turned on the tpms on both our Z’s.
– connected to my intimidator ss and everything was there
– Change one of my c5s that is canadien to US to disable the auto headlights because they don’t always open when they should and when they do work right they come on too early.
– Is now fully functional for F body, C5 and C6, It cost me a lot more than the initial $1000 that I thought was a good deal.
– Plugin to ’08 93 Aero and play around with the typical body and key features. My primary reason for picking up the Tech II was to program a spare key, it programs a new key was easily as 1-2-3 I figured ~$500+ at a dealer or ~$400 on my own would be well worth it…obviously if I received a working, defect free, unit.
– Used it to program my key fobs for my malibu but also have 4 other chevys.
– Changing some of the standard comfort features.
– Able to get security access using an old Dell laptop from my IT guy’s graveyard.
– Changed my key-unlock settings to all at first press, and then lock on drive off/open on key out was a snap.
– If you had a Tech2, you could possibly talk to the dealer and have them access their TIS system to load the BCM or PCM calibration to your Tech2. Some may do it.
If you can’t do that, just buy additional TIS2000 with USB key. The tis 2000 needs windows XP, Vista, win8.1, Win 7 32 bit.
– Compared with GM MDI, Tech2 covers more vehicles including OPEL, GM, SAAB, and Isuzu. About the programming: pretty sure Tech2 only program up to mid year 2012 model. At some point in the 2012 model year GM changed the interface method/tool. At this point the tech 2 became obsolete, so to programm the GM up to 2012, i.e 2013 GS Vert, GM MDI came instead of the Tech2.
-used it on GMC for air bag warning
-Tried it on 2006 Silverado & worked ok.
– Able to easily and completely program out the TPMS system
– To do two crank sensor re=learns and did the brake bleed on mine for the EBCM flush and it worked fine
– I am fairly certain it works on all GM cars til 2013. I have used it on my 03 GMC full size pickup, and 07 Trailblazer !!!! (and my 99 vette of course).
-If you have a 1997-2000, the TPMS is in the firmware and cannot be programmed. With the addition of the Z06 in 2001-2004, it can be programmed.
– Bleed the ABS ok.
– Used to cycle and bleed the ABS brakes on my C6 ok
-Plugged it in to 2011 Z06, and activated the Afterblow feature. I also cleared some old DTC codes that were in history. It works just fine and the quality feels genuine. It’s a pretty good knock off. Even came with all of the stickers from the Veltronix manufacturer. I assume they are knock off too.
GM TECH2 knock off works exactly like any others I’ve used at gm dealers over the years. It’s worth my money.
