DeltaDash Refresh Rate?
I currently have an Autoenginuity OBDII Scan Tool and I find that the refresh rate on it is rather slow. I'm looking into getting a DeltaDash, but I'm wondering if the refresh rate on the info it displays will be any faster. For instance, both of these can read engine RPM, but does it read & display it fast enough to be used as a shift light?
I'm hoping that the Deltadash is a bit faster in ready and displaying it's data since it's subaru specific while the autoenginuity is more of a general use device. And if it is, anyone interested in buying it off of me? Jason

To start, you are looking at apples and oranges here. Your current tool is OBD2 and works on most cars post 96. It follows the OBD2 spec, which is generally 200ms polling interval. On older ECUs this is about as good as it gets. On new ones, this is much slower than it needs.
The Delta Dash is late model Subaru specific. It is not OBD2 compliant, and will not work on other cars. It is also limited to a small number of cars that you own. (No scanning the entire club) However, since it is ECU specific, it can use the Subaru Select protocol, and have a much faster pooling interval. Before you do this, however, see if there is a way to change the pooling interval of your tool. For Elm32x based tools, it is a software setting, and you can pick whatever you want. I just went faster until I started getting errors, and then backed off. |

Wow, lots of good info. Thanks alot guys. If I can't increase the sample rate on mine, then I'll probably sell it and get the DD.
