iOS Software

The iPhone, iPad , and iPod continue to be very popular ways of interfacing to the ELM327.

A word of caution – the Bluetooth that Apple uses in iOS devices does not currently support the Serial Port Protocol (SPP). As such, iOS devices can not connect to ELM327 modules with Bluetooth – you must use WiFi with your device*.

AutoProPlus
AutoProPlus is a free app for monitoring your vehicle with an iPhone. A little difficult to figure out as the Owner’s Manual and web site are both very minimal.

BT1
Another bit of software that works using Bluetooth, but only if you also purchase the GoPoint Technology BT1 interface module.

DashCommand
Palmer Performance are here with another app for ELM327s and compatibles. DashCommand is a reasonable price considering what you get. You can also purchase enhancements that allow more than just generic data for many vehicles.

Engine Link
This app continuously monitors several engine parameters, but it’s not clear how you can modify (or stop) them. It does allow you to define custom PIDs though, which might be handy (depending on just what you are using the scan tool for).

EOBD Facile
The basic version of this app is free, and works well. It provides some vehicle information, and will read trouble codes, but you can not clear them unless you buy the full package. Once you’ve got to that point, you will know how you like the software, and the decision should be easy. Well worth a try.

OBD Car Doctor
A great little bit of free software. Provides all the basics, and works quite well.

OBD Fusion
A full-featured interface from OCTech that sells for a reasonable price. Does just about everything that you would want and now even offers support for the Apple Watch.

* We are aware that older iOS devices have serial data available at the 30 pin connector, but do not know of any software that you could use to take advantage of it.

top

Android Software

There’s a large number of Android Apps for talking to the ELM327. We’ve had to pare it down to a few of the most popular:

Car Gauge Pro
OBD Scantech’s app provides all the basics, as well as enhanced diagnostic data for many vehicles. The price is quite reasonable too.

CarSys Scan
OBD High Tech offers a free app that provides all the basics. For use with Bluetooth scan tools.

DashCommand
Palmer Performance also supports the ELM327 (and compatibles) on Android. This app only allows 30 minutes of (limited) use before you have to make your decision whether to buy.

eCar PRO
This software reads your OBD information through Bluetooth, but does more than just read trouble codes. You can see and compare sensor data, set alarms, display times, and calculate torque and horsepower.

EOBD Facile
The basic version of this app is free, and works well. It provides some vehicle information, and will read trouble codes, but you can not clear them unless you buy the full package. Once you’ve got to that point, you will know how you like the software, can decide whether to purchase the ‘Premium Access’ package. Well worth a try.

ELM327 Terminal
Designed to send pre-defined AT and OBD commands for you. It’s a free app that may be right for you.

Elm Basic
This is terminal program for sending commands to an ELM327 interface and receiving replies. Just what you may need if you want to stay in complete control.

FordSys Scan Free
Another app by OBD High Tech. This one caters to Ford vehicles, providing information from several vehicle modules as well as the OBDII diagnostics. For use with Bluetooth scan tools.

Honda Database
Need Honda trouble code or ECU info, or engine or transmission specs? If so, this handy app is certainly worth a look.

Kwik OBD Terminal
Another terminal program for sending commands to an ELM327 interface and receiving replies. Just what you may need if you want to stay in complete control.

Leaf Spy Pro
Owners of the Nissan Leaf will be interested in this Android app. There’s also a free version (Leaf Spy Lite) that will give battery info. The Leaf Spy Pro page on the Electric Vehicle Wiki is a must-visit too.

OBD Auto Doctor
This one is very similar to the iOS version, and it remains a free app too. A great little bit of software that provides all the basics and works well.

OBD Car Doctor
This one is very similar to the iOS version, and it remains a free app too. A great little bit of free software. Provides all the basics and works well.

OBD Trouble Codes Lite
Get trouble code descriptions on your phone or tablet. The free version of this app (ad sponsored) contains the generic trouble codes (from P0001 to P099F) in its database. The full (paid) version contains almost 20000 codes.

Piston (OBD2 & ELM327)
Marcin Gierlicki’s ‘Piston’ seems to be well designed, and worked well in testing. A free offering that should be one of the first to try.

RaceChrono
A popular lap timer app that logs both gps information and OBD data. The free version is time-limited, so if you find it useful, you will want to upgrade to the pro version.

ScanMaster for ELM327
A great free app from WGSoft.de, makers of the other ScanMaster programs. Should be one of the first apps that you try. Has in-app purchases.

Scanclic
Most of the OBD software available is in English, but if you prefer Italian, one company (Informaticlaclic) offers Windows and Android software packages that may be of interest to you.

ScanMyOpel Lite
This app is only for Opel/Vauxhall diagnostics, but that is exactly what many users are looking for. Try this Lite (limited) version before you decide whether to buy the full one.

Torque Lite
Free version of the popular app offers a lot for no cost.

Torque Pro
Is the full version of the app, which offers more features, supports more vehicles, and does not have ads.

TouchScan
This modestly priced app is getting fairly good reviews. If you’re looking for an app with a gauge type interface, this one is worth considering.

Note that most Android software requires that you already be paired with a Bluetooth device. We are often asked about pairing codes and while we can never know exactly what code would apply to your interface, we can say that most use either 0000 or 1234.

The EM327 is a microcontroller programmed to translate the On-Board Diagnostics (OBD) interface that you can find in most cars. ELM Electronics created the most recent and favorite of the PIC family of microcontrollers.

The ELM327 is the bridge between the OBD and the interface on your device that allows you to read your car’s system.

The parts of the ELM327 include:

1. The chip that serves as the brain of the device. Thischip is either created by ELM327 or is a copy of that chip.

2. Electrical Voltage adaptors that differentiate betweenthe various systems in the car.

3. Voltage adaptors for the PC that convert the info fromthe car into a form that fits your device.

  • 4 The Best ELM327 Adapters:
  • 5 ELM327 Apps
  • 6 ELM327 Software for PC
  • 7 ELM327 Adapters: Which One is Best for You?

ELM327 Interface

The ELM327 is the chip needed for your phones or PCs tocommunicate with your car. The ELM327 interface is the adaptor with the ELM327chip inside it that allows you to read those communications. It acts as a linkbetween your car’s onboard computer (ECU) and your device.

The OBD system in your car provides valuable information that helps you or your mechanic make needed repairs and perform standard maintenance to keep a vehicle performing. And the ELM327 interface offers you the access you need so you can interpret that information.

Functions of the ELM327

Features of the ELM327 include:

Reading Diagnostic Trouble Codes- This includes both genericcodes and manufacturer specific codes. The ELM327 is bi-directional, meaning itreads your car’s OBD and communicates with it.

The interface allows you to read the definition of each code and decide whether you can fix the problem yourself or if you need to take it to a mechanic. And your ELM327 can clear codes, so lights on dashboard turn off when issues are fixed.

Reading Diagnostic Data- The ELM327 goes a step further fromjust reading and clearing codes. It allows you to follow PIDs (PerformanceIndicators) and emissions data so you can manage your car even before thosetrouble codes appear.

The PID data appears in graphical form and gives you a clearpicture of whether your car is performing correctly. And emissions data helpsyou determine if your vehicle can pass emissions testing.

Tracking Live Data- The ELM327 follows data in real-time to help you understand things like your car’s engine performance or the fuel economy.

It records live data for over 60 different measuresincluding (but not limited to):

Average Trip Speed, Barometer, CO2 Emissions, RPM’s, Fuel Pressure, Speed, Torque, Trip Average Miles Per Gallon, Trip Distance, and many more.

Manages your Data- Data from your car logs onto your deviceand can be organized into reports. And those reports can be shared with otherswho have better knowledge than you do.

Protocols Supported by ELM327

The ELM327 is a significant improvement over previous models because those models only supported specific protocols. The ELM327, however, is compatible with protocols for almost all OBD2 model cars made after 1996.

Protocols supported by ELM327 are:

• SAE-J1850 VPW (at 10.4 kbit/s) or PWM (at 41.6 kbit/s)

• SAE-J1939 (either 250kbit/s or 500kbit/s)

• ISO 9141-2 (5 baud init at 10.4 kbit/s)

• ISO 14230-4 KWP (either 5 baud init and fast init, 10.4 kbit/s)

For

• ISO 15765-4 CAN (either 11 bit ID or 29 bit ID, 500 kbit/s or 250 kbit/s )

The Best ELM327 Adapters:

Bluetooth

ELM327 Mini- The device checks parameters in real-time alongwith reading and clearing codes. But it does not work with Apple products.

It is very simple to use, plug in, start engine, pair with tablet (or phone) after downloading app. .

Kitbest Bluetooth OBD2 Scanner – The Kibest monitors live sensor data and clear check engine codes. But it also is not compatible with Apple products.

This is a great tool for a very good price. .

Vgate iCar Pro- Depending on the power of your ELM327 app,the Vgate can run an emission test for you to see if you can pass before youtake your car over to the testing location. It also works with Apple products.

Product worked perfectly. No problems connecting via Bluetooth, and all coding went smoothly without interruption or error. .

Wifi

Kobra OBD2 Scanner & WiFi Car Code Reader-The Kitbest offers real-time data, works with most any car after 1996, and reads most major protocols. But the Kobra works with IOS and Android only.

It works well at a very good price. .

Wieppo ELM327 Wifi Adapter- The Wieppo works with alldevices. It also offers real-time dataand includes the library with 3000 code definitions. But the Wieppo doesn’twork diesel or hybrid cars.

Wsiiroon ELM327 Wifi Adapter- The Wsiiroom also works withall devices and reads fuel efficiency data as well. But the Wsiiroon will onlyclear your check engine light (so no airbag, transmission codes, etc.).

USB

ELM327 USB Adapter- This model USB adapter features greattransfer speeds of 500 kbit/s. It also includes advanced diagnostics, componentactivation, and service reset.

It easily plugs into your OBD2 port and communicates with the app on your phone. .

ELM327 Apps

ELM327 apps are available for both iPhone and Android. Theseapps check and clear codes, monitor dashboard information, and talk directly toyour car from your phone.

For the iPhone

Car Scanner ELM OBD2- The Car Scanner comes equipped with anextensive library of code definitions to help you clear most any check enginecode. The app also features diagnostic functions, a car performance tracker,and a trip guide.

This one is free andupdates frequently, but it doesn’t include all the advanced features otherbrands might.

The OBD Auto Doctor is one of the best apps for planningtrips. It alerts drivers with quick fuel efficiency data. A top gathering andreporting app, the Auto Doctor, is compatible with email.

The Auto Doctor reads and clears ECU codes and resets thecheck engine light. It also scans your emission status and pulls up live datafrom multiple parts of your car.

The Carista OBD2- The Carista costs more than most but is the best choice for customization. And it not only reads and clears trouble codes for your engines. The Carista also clears codes for the SRS and ABS systems.

And the Carista has a premium app that monitors tirepressure, retracts the parking brake if it gets stuck, and can perform a systemreset.

For Android

Torque Pro- The Torque Pro alerts you of problems in yourcar thoroughly before they happen. Along with clearing engine codes, itmonitors sensors and lets you know if your vehicle will pass emissions tests.

Torque Pro features a built-in dynamometer that measurestorque and RPM’s. It also measures your car’s efficiency and fuel economy.

OBD Fusion- The OBD Fusion reads and clears codes, keeps up withyour fuel economy, and displays a large number of gauges and graphs (includingRPM, engine temp, speed, etc.), so you can see how your car is performing inreal time.

The OBD Fusion supports more than 150 PID’s if you canmanage the way it drains your battery.

Dash Command- The Dash Command has most all the features theFusion has along with allowing you to check your emission status.

And Dash Command shows quick results if you have a newermodel phone.

ELM327 Software for PC

ELM327 software takes the data from your car and puts itright on your desktop or laptop.

For Windows

FORScan- The FORScan works for all versions of Windows goingall the way back to Windows 2000. It works for reading diagnostic codes andmodule sensors.

It runs diagnostic tests as well, but don’t get the Liteversion if you want diagnostic testing. The FORScan reads both generic andmanufacturer specific codes. It also displays data in text form.

However, FORScan’s are not compatible with all car models.

EngineCheck works for all gas-powered cars made after 2001and diesel cars made after 2004.

EngineCheck works almost exclusively with the check enginelight. It does include a handful other features, including live sensor data andfuel system status.

Freediag works exclusively with CLI (Command Line Interface). It reads and clears the Check Engine Light and is supported by five protocols (ISO 9141, ISO 9141-2, ISO 14230, SAE J1850 (PWM and VPW), SAE J2818/KWP1281/VAG), and the Mercedes Gearbox Protocol.

For Mac iOS

goSerial- The terminal interface reads and clears the CheckEngine Light and emission-related codes. It keeps multiple connections open atonce using a simple serial connection. And it’s completely free.

OBD GPS Logger- The GPS Logger compares code readings to thelocation of your car and downloads it on your computer. It allows you to trackhow efficiently your car is running and make a note of the place where yourvehicle started experiencing problems.

Also, the GPS Logger runs on OSX and Linux systems.

ELM327 Adapters: Which One is Best for You?

There are three fundamental ways to connect your ELM327 toyour device: Bluetooth, Wifi, or USB cable.

ELM327 Bluetooth Adapters

Since all modern phones (and many modern cars) have Bluetooth capabilities, Bluetooth works almost anywhere. You aren’t dependent on a Wifi network if you have a Bluetooth adapter. You can also buy these adapters at a very affordable price.

But Bluetooth adapters transfer data at a slower pace thanwifi. You also have to be within proximity of the car to get it to work. Thatmeans you can’t multitask while using this ELM327 adapter. If you use aBluetooth adapter, your vehicle will have to get all your attention.

ELM327 Wifi Adapters

Now keep in mind, most ELM327 wifi adapters aren’tconnecting to a local network. They create a network to communicate with yourcar.

Transfers happen quicker with a wifi adapter than they dowith a Bluetooth one. The wifi adapter reaches a greater range than theBluetooth adapter will. That allows you to shop for the new parts you need tofix the problem your ELM327 is finding.

And many computers don’t even have Bluetooth, but allcomputers have wifi, so the ELM327 wifi adapter offers greater variety in thekinds of devices its compatible with.

But most wifi adapters cost more. And you must remember yourpassword even if you set up an auto login. It can be challenging to get backinto your ELM327 if your device logs you out, and you don’t have your passwordon hand.

ELM327 USB Adapters

USB adapters are the true wildcard in this debate.

If your desktop or laptop is the device you rely on for car data, then the USB adapter might be your best option. All computers have USB ports, so you know it will be compatible. And many USB adapters produce high transfer speeds.

Range and mobility are the most substantial concerns withthe USB adapters. Some with significant range can read your car while you sitin another room. But others will require you to take your laptop into thegarage because of a lack of variety.

And most phones don’t support a USB connection, so thatlimits the devices you can use your USB adapter with.

FAQs about ELM327

1. How do I pair my ELM327?

Plug in your scanner into your car’s OBD II diagnostic port.Turn your ignition to the 2nd turn, so the engine stays off. Then, activate theBluetooth on your device and scan for your device. When the name of your devicepops up, click on it to pair.

2. How do I get ELM327 to work?

Plug in your scanner and turn on the ignition (the 2nd turnright before the engine is powered). On your device, go to settings, go towifi, then connect with the Wifi signal associated with your ELM327 (examplesfor names include WIFI ELM327, WiFiOBD, etc.)

After you’ve connected your device to the ELM327’s network,open your OBD app. Go to the app’s settings and set it to look for Wifi (it mayalready do this by default).

3. How do I connect my ELM327 to my iPhone?

For Bluetooth, launch the app and go to settings. Select the connection, then select connectiontype: Bluetooth. The search should produce your device. If it does not, click“update” to refresh the system.

For wifi, plug in your scanner and turn on the ignition (the2nd turn right before the engine is powered). On your device, go to settings,go to wifi, then connect with the Wifi signal associated with your ELM327(examples for names include WIFI ELM327, WiFiOBD, etc.)

After you’ve connected your device to the ELM327’s network,open your OBD app. Go to the app’s settings and set it to look for Wifi (it mayalready do this by default).

4. What are the risks of a Clone or a Pirate ELM327?

The ELM327 microcontroller code wasn’t copyrighted so anyonecan produce a copy of it. The clones and pirates are cheaper and featuresimilar abilities. But they are often buggy and don’t update (even if they saythey have).

For example, the first ELM327 put out by ELM Electronicsmarketed as version 1.0. Many pirate versions cloned the 1.0 software intotheir devices. But then, they traded “updates” (1.1. 1.2, etc.) that were notactual updates, just the 1.0 software pretending to be an update.

5. How do I spot and ELM327 Clone?

Elm327 Mac Driver

Check the version of ELM327 being advertised. An ELM327 withan interface of 1.5 is not a real version because ELM never realized thisversion.

Elm327 For Abs

And there are apps (such as Android’s “ELM327 Identifier”)that identify what version of the ELM327 chip is present so you can determineif the product is lying about how up-to-date it is.
