hobDrive Support

Hello,
I'm from Indonesia,
car : Aerio 2003
Engine Code : M15A (petrol 1500 cc VVT)
tested OBD dongle : OBDLINK MX and OBDII ELM327 v 1.5 (generic)
Phone : Android - Xiaomi Redmi 3

I tried many OBD softwares, but only Hobdrive and another software is OK (sv suzuki, sorry to mention) that worked.
Others software not even can connect with ECU.
Kudos to Hobdrive that can read Suzuki with good and user friendly interface.

with OBDLINK MX, all is perfect except AT Trainy sensor (another software is ok to display using AT gear position),
and then I want to buy cheaper OBD II, so I ordered ELM327 v1.5



With HobDrive Connection to ECU is ok, green circle in bottom left corner. But almost all sensor reading was a mess.
Throttle Position always zero and not response to accelerator pedal. Coolant Temp with negatif value, Air Temp with too high value, RPM and speed is jumping all over the place even when engine is not started. Fuel per Hour also too high even with engine off.



But my confussion is when I tried another software, everything is perfect, TPS, ECT, IAT, rpm, vehicle speed, all reading is perfect. But since it's display too basic not like hobdrive, I prefer hobdrive to run.

I checked with ELM327 identifier and find out in version 1.3 there are 2 unsupported command : ATJS, ATJE



Is it because 2 unsupported command that make sensor reading is not working ?

This is ELM327 identifier when using OBDLINK MX (that work perfectly with hobdrive) :


This is generic OBDII ELM327 v1.5 using another software, tried with gas pedal off/on and brake pedal off/on :


The other tried is I make HCI Snoop Bluetooth looking for PID for AT gear position with another software, read it with wireshark, but get confused I saved to google drive, may be somebody can look at it :

So, is it a matter of the generic ELM327, or is it something the way hobdrive read sensors is different with another software ?

Thanks in advance,
singachu

any thought ?
btw tried another ELM327 v1.5, tes using ELM327 identifier, all command from 1.0 to 1.4 supported without exception. But both sz viewer and hobDrive can't connect to ECU.....

Please give us a couple days. Well analyse your problem.

Hello.
Do the following with the adapter 1.5 to Hobdrive:
-Screens/settings/System settings/Logging level - Trace
-Screens/settings/Vehicle Settings/Ecu Settings:
Vehicle Ecu Type - Suzuki_JDM_KWP11
ELM Init String - ATPPS; ATSP5; ATAL; ATIB10; ATSH8111F1; ATST32; ATSW00; ATFI;

-Connect to auto
-Screens/Suzuki sensors. Make printscreen
-load file log.txt from hobd

You need to see how this adapter responds to the command ATPPS

Thanks for the info.
However for this adapter I already got refund since it's not work at all. Nice info anyway about the ELM 2.1 retag as 1.5

Hello, thanks for the feedback.
I'll do as your suggestion and will be back with the result.

Hello,

preparation :




suzuki sensor screen shot :


Log.txt :


btsnoop_hci.log, just in case it will help :


Result still the same, it's test with just key on, engine not started.

Hello.
Your adapter does not correctly return data - an extra byte at the beginning of the answer. Let's try to get around this problem programmatically.
And you did not enter the correct command ATTPS; but must ATPPS;

-Replace the file in hobdrive/ecu
-Connect to auto
-Screens/Suzuki sensors. Make printscreen
-load file log.txt from hobd

'programmatically' means there will be software update ? or is it just replace Suzuki_JDM_KWP.ecuxml ?

wow, it's work, very nice !





Thanks a lot.

I'll create another thread PID's related..still corious about ATF temperature, matic lever position and matic gear position.

I'll see what can be done with the ECU AT.
How will the test version be ready - I'll write

Do next:
- install elm327chat: https://play.google.com/store/apps/deta ... Elm327Chat
- save "SuzukiAerio_Eng_AT_1.txt"
- run elm327chat
- run auto
- select bluetooth ELM
- select a list of commands SuzukiAerio_Eng_AT_1.txt
- send SuzukiAerio_Eng_AT_1
- load log file from elm327chat

ok. I will test it tonight and will come back with the result.

The situation is such that the ECU boxes can not be read at the same time without changing the auto profile. Those. I can add pids for the ATU, but to display the parameters it will be necessary to change the profile, and the diagnosis of the engine ECU stops.
