Can We Get Dyno Tabular Data?
Often we argue over the differences in torque/hp between N/A and FI or FI PD vs. FI centrifugal, etc. Most of us have dyno graph pictures that we got from our dyno tunes. There is a lot of info in those plots, especially when, for example, comparing multiple cars from the same dyno, like on a dyno day.
If we could get the tabular data, a list of rpm and corresponding torque and horsepower, then we could create our own plots using Excel (or some other graphing tool). We could easily generate a plot, on the same scale, of three or four different combos to see where one combo has benefits over another.
Do any dyno tuners ever provide this data format, or does everyone just give pictures for the car owner to display at shows?

That's almost exactly what I mean. However, do can we get the data in raw file form, like .csv or .txt so that you can easily move it around in programs or share it with others? The latter is more what I was referring to.
When I got my car dynoed, I asked for this, but they said that the info is not available. It probably isn't available to dump to customers, but since shop owners have the ability to store and overlay plots, the data does exist smewhere. Also, as many of you have seen on the forum, when multiple dyno graphs are overlaid by the dyno mfg's software, there are often some anomalies with the scales. Having teh raw data and using Excel would eliminate that effect.

If you are using a Dynojet dyno ask the operator for the drf file from the run. Download WinPep from the Dynojet website, then open the drf file for viewing the graphs or exporting the data to a text file. Your text file then can be opened in Excel and manipulated to your desire.
