ECU Engine Pro

ECU Engine Pro
- Version 2.0
This app converts an Android device (phone or tablet) become a car (virtual) with an OBDII bluetooth adapter connected This is convenient and cost-effective solution for android OBDII software developing and testing

Hardware:Use 2 android devices (they are bluetooth paired), the one runs this app (in ECU simulation role) and the other runs an android OBDII app for testing (OBDII scanner)

Using this app you don't need a real car, stay indoor and do all testing before doing with a real carThe ECU Engine Simulation can affirm is running stable and reliable

This application has been tested with following android OBD-II apps:
* Code Reader Pro
* Torque Pro
* DashCommand
* ELMScanToyota The testing result is very good

Note: some android OBD-II apps used the bluetooth threshold detection can not connect to the simulation device, because the threshold of a real ELM adapter is different from the threshold of BLE on android device

The ECU Engine Simulation can also work well with command line on android terminal appsRecommended android terminal apps :
* Bluetooth Terminal
- SONWORKS *
* alOBD Terminal
- Alexandre Belloussov **
* Bluetooth Terminal
- Akexorcist

The ECU Engine Simulation works like a data server, so it waits (listen) for data request (AT or OBD-II commands) from external tester, then processing and responds to the request

The ECU Engine Simulation emulates OBD-II standard: ISO 15765-4 CAN 11/500KbThe app can process most AT commands, but the following AT commands are usually used with the ISO 15765-4 CAN standard:
* ATZ, ATWS, ATSP0, AT@1, ATI, ATH0, ATH1, ATE0, ATE1, ATDP, ATRV, ATDPn, ATSPn, ATTPn, ATCAF0, ATCAF1, ATSP6, ATAT0

OBD-II commands supported by this app 1. Supported PIDs requests: 01 00 : pid 0x01 to pid 0x20 01 20 : pid 0x21 to pid 0x3F 2. Live data PIDs: 01 01, 01 04, 01 05, 01 0A, 01 0C, 01 0D, 01 0E, 01 10, 01 11, 01 03, 01 04, 01 05, 01 21, 01 33, 01 46, 01 5C, 01 5E, 01 6A, 01 673. Vehile information: 09 00
- request supported PIDs 09 02
- request VIN number 09 04
- request calibration number4. DTC trouble codes: 03
- request stored codes 07
- request pending codes 0A
- request permanent codes 04
- request clearing trouble codes and relevant stored data5. Freeze frame data
- frame #0 02 00 00
- request supported PIDs 02 02 00
- request DTC that cause freeze frame data to store 02 XX 00
- where XX are PIDs to request other freeze frame dataHow to use this app:After starting the application, the starting screen appears and you only need to tap the button "Start simulating the ECU" to start the ECU simulation process, the data screen appearsOn the data screen you can live change some data that are visible on the data screen for the testing purposeAll other invisible data will be returned with fixed values

On the starting screen there are 2 information about the simulation bluetooth OBD-II adapter
* Adapter name: the name of built-in bluetooth device of the phone (tablet). this bluetooth device emulates the ELM327 bluetooth adapter
* Adapter address : the max address of built-in bluetooth device

If you do testing on command line terminal, there is an order to put AT commands as following :ATZ
- reset OBD-II adapterATSP6
- set protocol ISO 15765-4 CAN 11/500Kb (maybe use ATSP0 or ATTP6)ATH1
- if you want to view the header 7E8 in the response and ATH0 if notATCAF1
- if you want the adapter to format data for youATCAF0
- you have to format the request data yourself. in this case remember to add PCI byte (equal to number of data bytes in the request) at the first place in the requestfor example 02 01 0D : where 01 0D is request vehicle speed (2 data bytes) and PCI byte is 02

After init the OBD-II adapter with the above AT commands you can send what OBD-II request (or other AT commands) you want as usual
