If you’ve read about owners using the growing list of smartphone apps with adaptors connected to Volvos’ ports, this MVS Forums topic might interest you. Some recent questions:
- What app are you using to do so?
- Where did you get the app and what did it cost?
- What hardware is associated/required?
- What type of phone are you using?
- What data does it capture/display?
The “newest mini elm327” fit under the armrest quite well.
I got it for less than $20.I believe it will work for any blue-tooth capable phone.
I am using the Torque app on my android-based samsung galaxy s2. Downloaded on my phone from google play.
Torque is fantastic. You can try the free version first,
but the pro version is only $5 and is worth much more than that.
All these features work on the s70: (except for boost haha)
short/Long term fuel trim
O2 sensor voltage
emissions status indicators
Does 1/4 mile and 0-60 times.
Reads fault codes also, but I dont have any to test that out.
Was probably the best $25 I ever spent . . .
So what is fuel trim anyway and why do I care if I can read it? What does it matter short term/long term?
Has the ability to read any of this information actually made a difference in how you drive/maintain your car?
And notwithstanding that I can obtain all of this information, where can I obtain baseline values? So, for instance, even if I can determine that my intake manifold pressure is X millibars, what difference does that make if I don’t know what the normal spec. tolerances are anyway?
What I am asking is how valuable a tool is this in terms of real world applications for the data obtained?
