Thread: DashDaq data acquisition device?

  1. #1

    Default DashDaq data acquisition device?

    When I was at the Volt's homecoming event in Detroit last week a Volt engineer suggested I try the DashDaq data acquisition/display computer. Has anyone tried it? I already ordered it from Amazon but they haven't shipped it yet so I should be able to cancel. From what I understand it is very cool and it gives you over 400 data point and sensor inputs. I would like to get specifics on engine RPM, regen values etc. Apparently Drew Technologies have a Volt specific software package (for an extra $95!).

    If I don't get any feedback soon then I will provide some later in the week if I get it soon!

    Wonder how much of that data is really applicable to the Volt.

    I don't know about OBD ii vs i.

    Here's some ScanGauge data I got:

    Ok, got it today and WOW!

    It is picking up almost 200 parameters and the display is very nice. I bought a sticky disk from Radio Shack and can mount it with the suction cup to the left of the primary display screen (behind the turn signal lever) and can route the cable in the door seal. I am still playing with what sensors give me what information but so far I am impressed. I also have to play with the different themes since each theme has a different number of gauges and data value boxes. I also like being able to record timeline information on an SD card.

    I did have to buy the Volt licensing to get all the information but the inner engineer in me is very happy now!

    Do they have an on-line user's manual? What sort of info is available in the on-line customer support area?

    Does it display the state of battery charge and kWhs used/remaining since last full charge?

    Yes it does. There are about 15 parameters just for the high voltage battery alone! I will need too look and see which one will give you kWhs used/remaining since last charge (some of the data inputs are a little cryptic.) One piece of info that I found interesting so far is how and when the secondary motor is clutched into use. The main motor (B) will hit over 6000 RPM then if there is little torque change the other (A) motor starts being used and the RPM on the B motor drops by half. Also, it look like during regen the B motor is clutched again to increase RPM. Amazing that all this is going while being TOTALLY transparent to the driver. I have a lot to learn still about the inputs and the data.

    Looks like I have some reading material. If it looks good, I'll wish I had it during this 5.5K+ run. But I'm not driving to MI and TX (et al) again just to collect data points!

    Where's the pricing and information on the Volt license? I don't seem to be able to find it on the referenced web site.

    The price is $549 without the GPS nav feature and the Volt license is $95. I bought mine through Amazon which saved $15 and it was delivered through TunerTools. The Volt license is not on their website yet so I had to call and do it over the phone which was quick and easy.
