No reply on this? Anyone else use the fuel trim feature? I'm getting the bad feeling the cheap clone ELM unit I have is the problem... damn...

Dont expexct any reply to anything on here. Ever tried talking to God? Same response.....

Downloaded ScanMaster Lite and it shows the short term AND long term fuel trims, so its the Torque app at fault here- just letting the admin on here know, its not supporting a 2001 Toyota Tacoma 5vzfe V6.

Maybe it can be fixed before this is feedback on google play to warn others.

If I bought the paid version, would the fuel trims work?

Being a representative of God i have to answer, ...

i am a Bishop. that's a full stop after Bishop, ...

The only thing i can suggest is to use a variation of OBD2
devices and reload the Torque programme although this might not be necessary.

This can work though....

You may think it severe to delete the programme and reinstall but often it remedies the problem.

Kindest regards

re-installing it didn't fix the issue. Its a bummer, I like the torque interface the most out of the various apps I have used...

Have you looked at the min/max values for
the questionable gauge to see if that is in order?

What version of torque free or pro?

What year model vehicle?

Is it fully obdii compliant?

I highly recommend pro!

2001 Toyota Tacoma 3.4 5vzfe

Min/Max is 40% either way I believe, I'm game to change it to +/- 20%.

I'd get pro in a heart beat if it gets the fuel trim to work right. Then the torque plug-in's add all that much more to the package. But right now with piggyback tuning, its real critical to be able to see fuel trims.

Have you tried adding your own
extended PIDs for your fuel trim
to see if you get a correct response?

Sorry for how newb this is, but how would I load the correct PID?

In Torque Pro you can add extended PIDs
through settings.

I would think the process is similar for the
free version (except lack of header field).

If you know the mode/pid for the fuel trims
should be able to add your own version of
pids. (Using unique names).

Search vehicle specific forums for the codes.
I would think these should be readily available.

Which of the fuel trims are not responding
correctly? (Just B1S1 or are there others?)

Edit:

Bank 1 STFT
0106
(A-128)*(100/128)
%

BANK 1 LTFT
0107
(A-128)*(100/128)
%

B1S1 STFT
0114
(B-128)*(100/128)
%

B1S1 O2 Sensor Voltage
0114
A/200
Volts

I must be too much of a newb but I tried to input values and they did not save or I did something wrong, they would not appear as a PID that I could select.

Wanting to try something past my super cheap amazon adapter, I got the uber ScanTool MX. As of right now it's only pro over the amazon unit is it supposedly goes to sleep when the car is off, saving power. The features and calibrations seems to otherwise be the same.

But due to that purchase, I saw with OBDLink's PID list, that B1S1 short term fuel trim was also not supported. Turns out I have to use simply "bank 1 short term fuel trim" and cannot be sensor specific, that PID is not supported.

Torque light does not have the bank1 STFT PID, it only has sensor specific options, so I suppose that explains why it wasn't working for me.

Now the next challenge, I thought my truck simply had an on/off thermostatic switch for a dummy light for the auto trans, but reading up on the Scan Gauge II, it supports tranny temp readout. Neither Torque or OBDLink has that PID, so I need to figure out how to get that inputted into Torque (or does Torque Pro support it?)

Thanks for the update. Was wondering
how it turned out for you.

As for your latest challenge try...

686AF1 01B4
((A)*(9/5))-40
°F

Thanks for the PID tip but I get an "Unkown Error: Invalid int: 686AF101B4. I tried 686AF 101B4 and 686AF101B4 RXF

It does take 686af and 686af101

For fuel trims its not taking the formula with parentheses as written:
Bank 1 STFT
0106
(A-128)*(100/128)

It takes it as
(A-128*100/128)

01B4 is the mode/pid
686af1 is the header

The equation given for trim
came straight from wiki obdii
standard pids web page.

The equation editor in Torque
does not behave like a calculator
according to the developer. (As long
as the math is correct).

As for saving PIDs... make sure
you exit Torque from its menu
and not using task killer (back button).
Task killer can corrupt file on exit.

I did some more research and went and bought the paid Torque app.

Simply so awesome, it shows short term and long term trims, and a sick bonus it supports my gen's transmission temp. Paid Torque App FTW!
