I'm looking for suggestions or tips for using DataMaster to capture V-Tune data.

I went for a 30 minute ride today with my laptop secured in a bag recording data. I rode a combination of suburban and about 10 miles of highway driving. I tried to be very steady on the throttle and I delayed shifting to get the rpms in the upper range. When i was done, I only had two cells in the green. I guess I need to ride longer, probably closer to an hour.

Any tips for riding to optimize data collection?

The trick is to stay at one RPM for awhile to let it gather enough data to make a good correction. This can be done by dragging the brakes some to help you. Get the user manual out and do a little reading and it's all explained there. Also you might want to PM MJW930 here as he has done his bike and a few others.

I understand the need to keep it at a specific RPM so it can gather enough data samples for that RPM/throttle position 'cell'. I was wondering if the relative load on the bike made a difference. For example, I would think that the load on the bike at a steady 3000 rpm in first gear would be less that the same RPM in 3rd gear. Now that I think about it, I guess holding the same RPM in a higher gear would probably result in the throttle being more open, so it would be gathering data for another cell.

Side note, I wonder how well a small netbook computer with an atom processor would work to capture data. I bet a small 9" netbook could be mounted on a tank bag so you could easily monitor the data capture.

Thanks for the response, I'll give it another go later today.

I've seen guy use a 9" unit mounted to the top and just look at the data but we cannot recommend that unless of coarse you ware only doing this in a closed coarse area as it's unsafe to watch the screen while you ride. The use of various gears and brake draging will make it cover a larger area of the VE table.

Well, I went on a 50 mile ride yesterday and spent a bit of time riding the brakes to work in the higher load areas. I felt that I captured good data, but when I finished, only two cells were green, the rest were some shade of pink, so there was some data captured, but not as much as i would have hoped. I did work more area of the grid, so adding load with the brakes helped.

I think I need another session or two before finalizing the tables, but it is getting closer.

One of the things I noticed, is that I only captured about 1/3 to 1/2 of the actual data points that I would have expected. My laptop can capture about 5 frames per second, so an hour ride should capture around 18,000 frames, I think I captured around 6,000. I also noticed flat spots in the graph on the bottom of the window. Could this be from losing USB connectivity? I also was using a Thinkpad notebook that has the hard drive shock protection, I wonder if that messed things up. Might be time to spring for one of the solid state drives...

Thanks for the tips and feedback.
