content: I just watchedEEVblog #1181 - Car ECO OBD2 Fuel Saver SCAM(I got a youtube ad for the device earlier, which led me to Dave's video), and a comment in the forum mentioned theELM327. Interesting product, but I see it's discontinued. I guess there must be other similar products available.More generally, looking through the rest of their web site, I see they were in the business of providing ICs pre-programmed with useful little programs. Kind of a niche market, as it seems a lot of electronics hobbyists would want to do the programming themselves.

content: ELM327 got mass copied by the chinese and put into a module, selling for under $10. So I could see ELM suffering, the firmware effort would not pay for itself.

content: i have a few elm327, not sure one of them is genuine, for sure anything beyond v 1.5 is mostly fakes, i recall you have to send some commands to verify thatunless you find an genuine one v2 somewhere on this planetsent email to elm team, no answers ...now you have j2534 obd2 adapters who works pretty good

content: Nothing magic about OBD. It's just CANBus. Wikipedia has all the info you need to decode whatever you want on the bus:https://en.wikipedia.org/wiki/OBD-II_PIDsAny micro with a CANBus port would work. It's not particularly high bandwidth either.

content: A car as 2x can bus lines, with 2x different speeds, even if you have can bus adaptersIt is the software who help a lot for obd2 functions, it will not work the same as can bus interface, i have the "usb2can" module, sure you see the data streams, but you have to decode it in a sense, and to know from whom it came and where it goes etc ..... you work at another levelLike when people want to add some speedo projects, more modern dash interfaces etc ...ELM327 was doing the "magic", and with obd2 software tools you could do ECU AC Air bags ..... functions, and many other thingsyeah me too i should have bought the last v2 chips before they gone out of business,I do have some adapters who have the real ELM design, minus the latest v2 chip version ... the v1.5 leaked and now many pretend v2 etc ... which are all fakes, unless as i wrote you find an genuine one.You are stuck buying real obd2 tool like Autel, Foxwell, Creader, X431, Launch, VCM2 devices and many others "genuine" ones with frequent updates ....I have an Suzuki VCM2 who do Ford and GM cars, but not others ... and i paid a lot for itUltimate devices who support all the Can protocols ( Iso, Kw, SAE) will cost $$$, J2534 interface(s) where supposed to offer that at lower prices ?? obdexpress is a good place to find many things but ... not cheapNot a 10-20$ "ELM" device

content: Quote from: mikerj on April 24, 2024, 08:17:15 amSure. Should have been more specific. The ISO 15765 Canbus port on Pins 6 and 14 is just Canbus."...as of 2008 all vehicles sold in the US are required to implement CAN as one of their signaling protocols."
