using a 6-pin ON / OFF / ON switch, to switch mode according to OBD2 protocol of the vehicle. It is easily possible to add CanHS and CanMS mode for Ford. xx $ instead of $ 25īut after seeing a disassembly of one of its obd2 scanner that had a main chip GDM32 (Like STM32?) and lm393 and lm317 with MCP2551 very similar to the components of the circuit ELM327 which my separated from this interesting model is the lack of tutorials, the price is affordable, lcd screen and features similar to OBD2 adapters but i prefer OBD2 ELM327. Otherwise it is even possible to realized it with the old with PCB to hole and wires everywhere and the ELM327L i saw version 1.3 a or b for $ 17 at ELM, the 1.4 is out of stock and is no longer produced (+ 8 $ postage) During my research i also came across a scanner obd2 the CR3001 sold at this moment to 19. If i can only replace the PIC18F2480 clone chip without touching the other components by the ELM327MS. Some sell versions that do not exist at ELM (Canada) "I would like to take this opportunity to say, respect to the developer of ELM (Canada) i would like to buy a chip ELM327 with new firmware 2.2 out of respect to the project developer, It is impossible for me to find accurate information on clones because in China, whoever opens a factory can manufacture what he wants (+/-).

If so, they may have simply injected the cloned version v1.0 code with improved firmware (Shenzen mode). incredible but it is not as stable as the PIC18F.Īccording to long research and i'm not 100% sure it says that this little hidden chip could be the STM32F042. It worked almost like the PIC18F RPM in real time, engine temperature, air pressure.

What surprised me especially it was the mini blue clone with the so-called invisible chip version 2.1 by the vendor who is visible as version 1.5 on the test software and has a good MAC address 00: 1D: A5: 68: 98: 8B.

Today i tested the clone model with PIC18F25K80 and a free application (DashCommand) using an android samsung, i was quite astounded by the display of several probes in real time.įrom the simple speedometer to fuel consumption and a lot of other useful info that i did not understand, my old Peugeot was a formula1 Here i am happy to share this adventure and i hope to facilitate the search for future customers good OBD2 adapter the last 3 photos show the ideal OBD2 (from $ 15). I'm waiting for the 4th OBD2 (mini bluetooth) i think it would be the same as the ATDIAGįinally after all the research, shopping "cheap" and tests, i think the ideal would be the one with the chip PIC18F2480 or PIC18F2580 with MCP2551, LM317 and LM393 which would be the most complete OBD2 clones, the one with 18F2480 chip automatically has all the necessary.Ī tip is that in general its adapters have visible light LEDs, we can see the colors of the leds from outside the OBD2 boxes, the boxes with LEDs like the one present are not very good.

It has the 18F25K80 chip and a CAN chip "tja?" 1050, BEKEN BK3231S bluetooth chip, 5V 78L05 and 3.3V AMS1117, crystal 4000 (good according to users).įor the tests, it is more efficient, reads more probes, gives more information but remains limited. I think it's worth it without being a bargain. Good finally this adapter OBD2 works better than previous. Which means that in reality it is marketing to make fans like me believe that this is a good deal after opening the box to see the PCB, i quickly understood the little game seller
I received the OBD2 bluetooth adapter with chip PIC18F25K80 and here are my impressions, already the seller is in continuous sales with "either say" 54% to 56% in continuous
