it's possible but you need to find the adress and formula for it

fuel trim seem suspicious indeed ... normaly near 0

unless some manufacture decided to switch too 100% as normal or something

for timing some if i remember correctly some will show timing advance in negative ... since it's before 0

Thanks for your reply.

Any ideas how to find those please?
Yes the trims look strange ?

Ok got it, probably works this way.

what engine do you have?

Wow that's great, thanks a lot!

Now I have to figure out how these can be used to get the data shown to the app.

Hello,

Found how to insert extra PIDs to Torque, some reading was needed of course 🙂

EGT worked fine with the data provided
PID 2218BA
Equation Signed(A)*256+B
Min value -32768
Max value 32768
Unit type °C
OBD Header to use DA10F1

Oil temp does not though, I get
Result for equation: [No response]
Command: 221302
Response: 7F2231

If I use it like this
PID 221302
Equation B
Min value 0
Max value 255
Unit type °C
OBD Header to use DA10F1

Anything I could look at please?

Thx!

Try the app AlfaOBD Demo, will it work with your engine and what type of ECU is suitable for your engine

Thanks, works ok with AlfaOBD, estimated oil temp is displayed.

ECU IAW 8GMF CF5/EOBD (eng. 1.4)
Harfware number: MM8GMFHW503
Homologation number: 8GMFA5

Does this mean it should also be displayed in Torque with the data you provided?
Also interested in Calculated Advance data as Torque displays strange negative numbers and fluctuating numbers?

*Have also images to upload but not sure how 🙂

Estimated oil temp, 221942, (A*256+B)*144.177/65535, 0, 144, °C, DA10F1
Calculated Advance, 221811, Signed(A)*256+B, -180, 180, °, DA10F1

No luck unfortunately 🙁

Oil temp displays a value of about 1 at idle and rises to 3-4 with light throttle and advance shows strange values.

make an exchange log via Bluetooth for AlfaOBD (btsnoop_hci.log)
you need to enter developer mode and enable BT exchange log recording (Bluetooth HCI snoop log)
write what response the ECU gives to such requests
22F100
22F1A5
221000
1A87

you can upload screenshots to any file hosting service, and post links here

Thanks, will try to create the btsnoop_hci.log file, think I found how to do it.
How do I send the 22xxxx commands though to the ecu?

Create a new PID and do a PID Test, you wrote that the answer to request 221302 is 7F2231

Oil temp does not though, I get
Result for equation: [No response]
Command: 221302
Response: 7F2231

Did not manage the BT snoop log but used a serial port analyzer with Multi Ecu Scan and almost sure I have the addresses (very close to the ones you gave)

Oil temp 22194F
Advance 221812

Need to figure out formulas and limits as the ones you gave are probably not valid, oil gives a value of 0.2 while it is about 100 and advance is kinda strange.

Got it about sending commands with PIDs, sorry.
Do you still want me to do it?

Appreciate your help!

Great thanks!

Just figured out the equation of the oil temp myself before you replied and it worked 🙂

Timing advance seems to be fine with the data you supplied!

Do you know if this engine has a wideband oxygen sensor so I can display AFR?
Did not manage to find any 0-5V readings either in AlfaOBD nor in MES.

Is it too much to ask how do you find min-max values, why did you ask to send these requests etc? Always keen of learning bud 🙂
