That is, XHorse made a J2534 adapter and called it Mini-VCI, got driven out of the business by counterfeiters, and now you can buy cheap counterfeit Mini-VCIs from China and they will work with Techstream, except when they don't.Īlso in the J2534 category are VxDiag (about $80), Openport 2.0 ($169), Drew Technologies Mongoose ($495), and "Mangoose" (a counterfeit Mongoose, priced about the same as counterfeit Mini-VCI). The Mini-VCI is a J2534 adapter at least that much can be said for it. And there are several procedures (calibrating various parts after replacement, brake bleeds, fob registration) that do not all have chicken-dance alternatives in all generations of Prius, so at some point there may be something your car needs that only a J2534 adapter will be able to do. Being able to test parts of the car actively can really speed up your diagnosis of a problem. On top of being able to query all of the ECUs that exist in the car, there are also a large number of active tests that, to my knowledge, nobody has duplicated in a phone app, though Carista has at least worked out some of the customizable setting tweaks. The capabilities you gain are not just reflashing ECUs. I'm not aware that anyone has achieved that without using Techstream, which requires a J2534 adapter. To the best of my knowledge, although there are reverse-engineered collections of various Prius PIDs that you can read with an ELM327 and Torque, etc., that is nothing near all of the PIDs available, or communicating with all two-to-three-dozen ECUs in the car.

there are ELM327 adapters, and there are J2534 adapters these differ in their capabilities and in how the software talks to them. sub-$30 for most counterfeit Mini-VCIs), there will naturally still be people who say "I don't care about those issues and will take my chances on the cheap one", and there may also be some who say "$169 ain't bad to align my purchasing with my values, or to gamble less on reliability", and there's room in the world for both.Ĭlick to expand.There's some category confusion going on here. Are interested in supporting a company that is still actually doing its own R&D, production, and support, rather than random offshore counterfeiters.Īt the price difference ($169 for an authentic Openport vs.And the only "solution" is "try buying another Mini-VCI, maybe you'll get one that works. You can have a Mini-VCI/Techstream combination that works great for you, and recommend it to somebody else, who goes and buys the (supposedly) same combination, maybe from a different eBay seller or maybe not, and it will have some nonsense quirk like being able to talk to every ECU except the engine, or flaking out in the middle of brake bleeds. That's the biggest issue with those things (and since the counterfeiting succeeded in driving XHorse, the original maker, right out of their own business, you can't buy one now that isn't counterfeit).

Aren't interested in gambling on the quality-control issues of the counterfeit Mini-VCIs.The Openport option will be mostly of interest to people who:
