Review 1:

Tool arrived. All work fine!!! Cadillac 6L45 TCM clone ok. GM Acdelco E39a clone ok.


Review 2:

GM TCM T87 and T87 you can do it yourself, full reading and writing. That was only available for flex, B-flash. Now i finished it with dc706. Amazing!


Review 3:

The DC706 is a good tool especially for the money. It is a bit clunky to work with the files. Otherwise, it’s a very formidable tool. We use it often on the DPS6 Ford TCMs as it is easy to connect when working mobile.


Review 4:

9GV OBDSTAR reading fine with everything included nothing separate!!! Very good device!


Review 5:

Audi Temic VL381 0AW gearbox clone ok. The dc706 obdstar did it perfectly. Not everything is flex or dim. And not fc200 either.


Review 6:

Fiat IAW 9gv is done, same as IO terminal without opening it. Amazing!

OBDSTAR DC706 is a good tool for PSA whatever.

Review 11:

I picked up this tool a few weeks ago and have spent some time testing its capabilities. The DC706 is a tablet-based ECM, TCM, and BCM cloning tool, advertised as being able to read and write memory areas (eeprom, D-Flash, P-Flash) of supported control units, as well as some pin code extraction, all through OBD or bench mode (mostly bench).


The tool this most closely resembles is IO Terminal. I am not labeling this as a comparison because I have never used IO Terminal, nor do I wish to open a debate on who cracks or pirates whose software, that’s above my pay grade. I’ll stop short of calling this a review because I haven’t fixed any cars with it yet, I’ve only tested it on various modules.


I had been considering the purchase of the IO Terminal for some time for in-house use. As an independent repair facility, where I see the benefit of this type of tool would mostly be on the GM global A stuff, TCM’s in particular. As we all know, GM’s transmissions are a weak link. One of the running jokes in the shop when a 6L80 equipped GM is towed into the shop… is it here for its 100,000-mile transmission replacement? Thus far we have been able to sell a factory or Jasper remanufactured transmission only requiring SPS2 programming. But as these vehicles age I envision used replacements will become an option for some based upon financial means and vehicle depreciation. Also in today’s world of hit-and-miss module availability, this type of tool can provide another option. Tooling and software from Kess V2, Flex, PCMflash, and the like are not financially practical for sporadic in-house use, and I’m not likely to market module cloning as a sublet service anytime soon. The cost of IO terminal hardware and the various software packages can add up and has kept me on the fence about purchasing it, unsure of the return on investment.


I saw this dc706 ecu tool from OBDStar and it seemed intriguing. OBDStar makes some immobilizer and odometer correction tools, as well as motorcycle and marine scan tools. This new tool is offered by OBDStar and has been on the market for about 6 months.


Checking the module coverage list it was pretty much identical to IO Terminal. The price point was good at about $1,400 for the full software version (ECM, TCM, and Body/other) plus another $100 for their P003 adapter for certain modules. It seems like the subscription fee will be a couple of hundred dollars a year to keep it current. So I decided to roll the dice and give it a try.


The first thing I noticed after activation of the tool was a version update that now includes ZF 8HP TCM’s on all makes, including Dodge and GPEC-4 PCM’s in boot mode. In addition, I turned the tool on a few days ago to discover another update that amongst other things included GPEC-2, 2A, and 3 PCM’s. It’s encouraging to see regular updates and expanded coverage.


I gathered a bunch of modules to test: E39A and E92 GM PCM’s, 2 FCA RF Hubs, a Ford continental BCM, a GM Bosch BCM, and a GPEC-2 PCM. Guide and pin out diagrams are clear and accurate. Performed all reading and writing on all of these modules easily and successfully. VIN’s were visible on eeprom and d-flash sectors, as well as pin codes.


Deciphering some of the verbiage while using can be a challenge, but already having Chinese tablet-based scan tools from Launch, Autel, and Topdon, I consider Chinenglish a second language. An example of this is in photo number 2 while reading a GM Bosch BCM in bench mode, it gave me pause when I first saw it, but I speculate it was telling me not to wake up the BCM with ignition source voltage during read, and write operations. I proceeded and successfully read and write the BCM.


No tool like OBDSTAR DC706 ECU tool is perfect, I’m sure holes and flaws will be discovered, but at this point, my confidence level is pretty high. I just hope it comes through when I need to use it “for real”.


I wanted to share this with those who may be in a similar situation, it may be worth considering this tool.
