Description
ECU Engine Pro - Version 1.4.6
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 car The 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 apps
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 11/500Kb The 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 67 3. Vehile information: 09 00 - request supported PIDs 09 02 - request VIN number 09 04 - request calibration number 4. DTC trouble codes: 03 - request stored codes 07 - request pending codes 0A - request permanent codes 04 - request clearing trouble codes and relevant stored data 5. 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 ask other freeze frame data
Usage: Button "Start simulating the ECU" : the data screen appears On the data screen you can live change some data that are visible on the data screen for the testing purpose All 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. 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 adapter ATSP6 - set protocol ISO 15765-4 CAN 11/500Kb (may use ATSP0 or ATTP6) ATH1 - View the header 7E8 in the response or ATH0 if not ATCAF1 -The adapter to format data for you ATCAF0 - Do format the request data yourself. in this case remember to add PCI byte (number of data bytes) at the first place in the request for example 02 01 0D : where 01 0D is request vehicle speed (2 data bytes) and PCI byte is 02
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
Support extra PIDs for testing with ISO 15765-4 CAN 11/500Kb protocol Header: PID (Ford) 7E0: 221E1C/2209D4 760: 223A51 Prius Gen2 7E2: 21C3/21C4 7E3: 21CE Gen3 & PHV 7E0: 21C1 7E2: 21C2/217D/2181/2192 7B0: 2103 7C0: 2113 Privacy policy : https://www.freeprivacypolicy.com/live/94233689-4b2c-4217-aa1e-91a4ab0572ef
