ELM327 OBD2 USB Adapter for Windows, ELMconfig Scanner with MS CAN/HS CAN Switch for Scan F150 F250 Car and Light Truck Check Engine Light, Diagnosis on Windows with V1.5 Chip

The OBDMONSTER scanner has been a game-changer for diagnosing issues on my vehicle. It’s compact, easy to use, and connects quickly without any hassle. The interface is straightforward, and it provides clear, accurate codes with descriptions, which makes troubleshooting way easier—even for someone who isn’t a mechanic. I’ve used it to reset check engine lights, monitor real-time data, and verify repairs, and it’s worked flawlessly every time. For the price, the quality and functionality are unbeatable. Highly recommend for any DIYer or car enthusiast looking to stay ahead of maintenance.

Worked as expected. Easy to install software. Forscan recognized it and I was able to modify and update my settings. Need to put the key at "On" and not just "accessory" to get it to save the updates.

Ford/Lincoln/Mercury vehicles have PATS modules that use a 40 or 80 bit transponder built into the key to allow the PATS module to clear systems for vehicles start and run.There are a few ways to get more keys for a Ford PATS equipped vehicle:1) dealer avg price 1 hr labor and tech time plus key(s) $200+2) Locksmith - same as above3) This cable and ForScan software cost? This cable.Being a wholesale auto dealer, many times we get vehicles with 1 well worn key. With no keyless entry remote - paying some company or guy/girl $250 for a $3 Amazon key to be programmed to the car is literally stupid - especially when YOU can also buy the same exact $3 Amaxon key and program it yourself - total cost?, $3. Thats right, 3 bucks. Key and remote fob? $12 total - programmed yourself.,,,(search ForScan) i saved $800 with my first use of this cable with ForScan - you can too!** note that with this cable and ForScan ive been able to program everything (on Ford Products) from an annoying seatbelt chime permanently off on a 2011 town car to adding OEM Factory trailer brake controllers with computer assisted hands free trailer backup on very late model (2017 and up) F150/250/350s - ive also edited config "AS BUILT" PCM options on 2 dozen Ford GM Chrysler vehicles - ive been programming out GM Active Fuel Management and engine start stop to default to OFF when on. I also have a 09 town car with a 660hp 32v 4.6 and ProCharger that i can use this to optimize fuel maps and even add factory remote start and much much more! This pays for itself first use - YMMV and PLEASE BACKUP YOUR STOCK OEM AS BUILT CONFIGURATION BEFORE YOU DO ANYTHING!! Computers do crash- or die for no apparent reason, should it do so mid programming, if you dont have a saved as built pcm file, you wont be happy for a looong time. And it will cost you thousands for a new PCM programmed to your vehicle - thats worst case scenario and RARELY happens -Note: ForScan does display on screen "THIS CABLE IS NOT COMPATIBLE WITH FORSCAN" of course it isnt, (works fine) they sell their own branded cables, which are exacrly these cables. Save money - buy this one

I wanted this to hack on for an electronics project and I didn't care about the USB functionality at all. I just wanted a simple way to directly interface with the ELM327. I was afraid that the unit would be like other "ELM327" clones that place the microcontroller under blob of black epoxy, making it hard to interface with.Fortunately, this unit comes with a Microchip PIC18F25K80 (which is what the real ELM327 should be using). Whether it's flashed with the real firmware is unknown, but it behave identically enough for all my use cases.In the photo, the largest chip in the center is the PIC18F25K80. The SOIC-8 chip above it is a CH340, which a USB-to-serial translator. The SOIC-8 in the top-right is a SIT1040, which is a CAN transceiver. I believe the random assortment of FETs and resistors in the bottom right are for the ISO-L, ISO-K, and J1850 buses.Of note, there are no voltage regulators in the unit as it takes 5V directly from USB. For my use cases, I'll essentially be de-soldering the CH340 and connecting a custom-built board into the 5V, GND, TX, and RX lines.EDIT: The voltage reading is inaccurate by about 0.2V. The circuit here differs from the recommended circuit in the ELM327 datasheet in that there is a Schottky diode between the Vbat and the ELM326's ADC. The diode has a voltage drop between 0.15V to 0.25V. I guess the diode provides extra protection, but it affects voltage reading accuracy. If you feel inclined, you can desolder the diode and put a bridge wire in its place.

Apparently FORScan only supports certain OBD II adapters, and this isn't one of them. I was able to clear transmission adaptive tables, disable the key-in-ignition chime, and of course read trouble codes. When I tried to enter the PATS procedure to program a spare key, FORScan refused to enter the procedure due to not supporting the adapter.

super recommended.If I were to buy it again, it generates results instantly

DO NOT BUY THIS ADAPTER!!! It doesn't totally work with FORSCAN as a few Amazon customers found out, read the reviews. Look at the Amazon webpage title. NOWHERE DOES IT EVEN SAY "FORSCAN" IN THE TITLE. Recommend using FORSCAN WEBSITE approved adapters that are "MADE FOR FORSCAN". LASTLY YOU CAN SEE IT'S A 'FREQUENTLY RETURNED ITEM' PER AMAZON.

Bought this to use along with forscan to change some settings on my ford explorer. Very easy to use. You can also use this along with forscan to read and erase diagnostic trouble codes for your vehicle.
