The durametric software makes a graph in excel by itselve,when you make a run to log some data,you just have to push a button EXPORT on the durametric software and it converts all data to excel.The only thing I did was adding the A/F to excel.Maybe your software at the durametric is not set up correctly because you can choose in saving data in excel and something else which I forgot.

 

Mine lets me export into exel, but will give me a spreadsheet. It will, not graph a/f automatically in exel thou.

 

You need to read the Excel manual...and it depends on your version. Go to help and input line chart...it will explain it. You will select the column you want charted and click the line chart button and voila.

 

Ya, Voila

I'm not slow by any means But selecting two ranges of data and graphing it on the x&y axis, taking into account that the AFR is not linear data and needs to be allocated to particular RPM during a run cycle is not as easy as 123... I wish it was, cause I wouldn't need to ask.

 

Anyone know where to get definitions and normal ranges of these items:

I was playing with my Durametric yesterday and I also would love to see a Guru who can explain all these parameters....Except of course the obvious ones...

 

I might buy Auterra Dyno Scan (even if it is a POS).

Here is the Manual that has definitions starting on Page 50 (no idea how they map to Durametric):

Very useful Thanks.

 

This looks like the way to go (click on screenshots)

http://www.auterraweb.com/dashdynopropack.html

its had a pass thru to the pc software, but it also can be used with out a PC to display almost anything (including fault code and reseting). Question is "does it actaully work".

Its like 379 - I think I am going to try it out.

 

Just an FYI, I talked with someone that knows a little about Durametric and there are a bunch of formula's that can be applied to "Actual Values" to get BAR etc. I let you know when I know what they are.

 

I will test my theory on the way home, but this is how I think you can get to BAR from the Durametric.

"Boost pressure of sensor" is an Actual Value in the Durametric and it is displayed in mbar. In my car, at idle it is 990 (this number will vary depending on how high above sea level you are - I think). The standard atmosphere (symbol: atm) is a unit of pressure and is defined as being equal 14.696 PSI, 1013.25 mbars (at sea level). 0 Bar reading in the car is actually equal to 14.696 PSI or 1.013 BAR (at sea level) so the gauge is a measurement above atm (the Durametric is a total reading). 1.0 BAR reading in the car is an additional 14.696 psi or 1 additional bar of boost pressure.

Under acceleration, if I record a reading of 1569 through the Durametric it needs to be converted to match the reading on the gauge in the car.
1568 - 990 (reading at idle) = 578 mbar / 1000 = .57 BAR or .6 bar on the gauge or 8.5 psi

I'll let you know if my theory is a pile of crap or not

 

some OBD-II Parameter stuff

http://en.wikipedia.org/wiki/OBD-II_PIDs

http://obddiagnostics.com/obdinfo/pids1-2.html

 

Anyone know what the Actual Engine Torque value means? And what unit of measurement it is?

 

So I did my little test on the way home.

Vehicle Speed is converted from km to mph
Diff is Boost Presure from Durametric minus Baseline which is a column I added
BAR is Diff / 1000 to go from mbar to bar

I saw 1.2 bar spike (17.47 psi) on dash - never saw that before....but confirmed by my theory

 

Something I learned by experience is if you use a power adapter on the laptop, your sampling rates will increase, on battery the rates decrease nearly to the point that logging is nearly worthless. I dont have performance metrics, but my tuner can definitely see a significant difference. I bought a small converter at best buy and keep it in the car for when I do data logging.
