Post CSV File - Blank Data
on: April 27, 2011 (GMT)

I am attempting to log some data in the CSV file format so I can bring it up in excel. I have added the PID’s that I want to show up. When I import the CSV file into excel, the PID’s that I entered just show blank data. The title is shown at the top of the column but just blank data after that. There is data that is recorded, but I believe that is all generic data not dealing with the OBD2. I was hoping to log some of this information during autoX and would like some guidance on how this can be done.
Thank you,
CC

Hi

There was a bug (which is now fixed in the latest version on the market) which prevented som PIDs from being logged correctly. Update and it should start working for you (provided you have setup what to log in the logging settings)!

Hope this helps

Ian

I have Torque Pro 1.8.158

Same problem, o2 data is not present in the .csv File.
Weird, because the data is shown in realtime graph.
STFT, LTFT , MAP, and other, no problem.
O2 always empty. What could be the problem ?

Is it possible, that time intervals could influence
some PIDs ?

For some reason 100 ms seems better
to log than 1 second. Anyway, it is still a problem ,
that PIDs like O2 Sensor or Long term fuel trims
show a dash sometimes , instead of a value .

Hi!

I’ll try to have a look at this during this or just after the current update – it could be that the sensor update is so slow (from the vehicle) that the sensor is timing out and therefore removing it’s value (as it’s out of date)

Hey,

thank you !
I tried some other software.
Its definitly caused by torque.

Hi!

The other software likely does not expire out of date data (ie: it logs old data to the log file). Make certain that the reading it is logging for Time X is not from several scores of seconds ago.

The speed at which data is read in OBD is governed by how many sensors you have set to log. if you have a lot of sensors logging then your refresh speed will take a long time for any one sensor and that can cause the readings to be expired (meaning, the data is considered to old to be logged for that ‘time’ as it may have been from several seconds ago that it was last updated – to prevent you from using incorrect data)

Reduce the number of sensors being logged to get faster data refreshes so you don’t log data that’s no longer relevant in the current time period

Hi,

right now everthing is fine.
Unfortunately, i dont know why.
Its not depending on how many PIDs are active.
The bluetooth adapter and the car is also fine.
Interval is 100 ms and it works (against all odds).
But i guess, one have to wait just a few seconds longer
before start recording, so the ecu is connected properly.
And: the app could be much greater with an oscilloscope
with every PID in a separate row. Think about it and
thanks for your help.

Just as a side note (and for completeness) – It’s important to note that O2 data is not usually available from the ECU straight after and engine start (especially when the engine is started from cold)

This is because the O2 sensors need to heat up to a couple of hundred degrees C before they become operational, and this takes time to do.

Some engine ECUs do not respond to this PID until the engine has entered ‘closed loop’ state and will also cause the app to not be able to retrieve a value for the O2 sensor (Other ECU’s respond with a static value or the current (cold) value of the sensor in it’s non-operational state)

I used a BT-Adapter with 120 ohms between Pin 6 and 14.
on a canbus system. Could this be a problem too ?

Strange , because the usb version has a switch,
and this resistance is not there anymore, no problems.
