What does the SOLO or SOLO2 really do for you? Yes you can get your lap times but its so much more. Let me explain. Over the winter months I will show you how to improve your program using this tool.

I am using some data from the 2018 World Final Event as our example. This track was very small, and the laps I will be looking at are within .128 of each other. On a large track that is a very small number, however on the bull ring at IMS its huge.

The Blue line on the graph was the slower lap - 11.135 while the red lap was the faster at - 11.007

Lets look at the Track Map first. 

The software will produce the track image, it will define corners and straightaways and show you the start finish line at a minimum. Upon closer look it will show you and approximate length of the driven track too.

Now lets look at a graph (Time vs Distance) and see what it can tell us.

As we mentioned the Blue line is slower on the stopwatch.

How can that be?  with the exception of one area the blue line is faster than the red especially out of turn five and through turn six heading to the start finish line.

The graph clearly shows that after the start finish line heading into turn one, the driver over slow the kart on entry into turn one, but as the kart exits turn one the kart has a higher exit speed leading to turn two.

From this data, we know to tell our driver not to over slow the kart entering one, 

But is that why we are faster every where else? To find this out we need to look at where the driver has been on the track, the GPS will allow us to look at these differences.

I think you might be reading your graph incorrectly. Time is on the side (vertical axis) and distance is on the bottom (horizontal axis). If this is the case then the blue line is slower than the red line because it is associated with larger times per unit of distance, except for the first dip in which it is faster than the red line because of the lower time per distance ratio. The red line is faster than the blue line because it is associated with smaller times per unit of distance, except in the first dip in which it is slower than the blue line because of the higher time per distance ratio.

Stu, Taking a look at the lower section of the graph this section is referred to at the Delta. The Delta is the difference between the 2 individual laps in this instance being the red (faster lap) and blue (slower lap). Pretend these 2 lines are separate drivers on track in the race. Driver in the blue had made a mistake early on in the lap causing about a 1.5 tenth gap between the 2 drivers. Although he had fasters speeds in spots throughout the overall lap, the distance lost on that first section of the lap was too large to make up throughout the rest of the run. 

You can see exactly where throughout the lap the driver had made up time and/or lost time. Anytime the blue line goes upward that indicates time has been lost to the reference (faster) lap. When the line drops downward they are gaining time towards the reference (faster) lap.

To confirm our visual reference lets add the Longitude reference. The new graph shows that leading up to that point our kart is in fact slowing.

The red line shows negative G's or .19 while the blue line shows the kart is experiencing negative .43 G's. - So with that, had the driver not over slowed the kart, we would have had a much better lap time.

Next up will be using the GPS data to determine which line through a corner is faster. We will also be able to see how the kart is working, was it loose or over stuck? How was it on entry vs exit.

Are you begging to see the power of this tool?

The GPS data can be extremely useful for driving instruction. Using the speed reference the blue line in most places was faster than the red line, With the GPS we can see the difference in the placement of the kart between the two laps. 

Sorry had to change the colors to be able to see it . Note the Yellow lines represents the slower lap (Blue for those that are keeping track of from home) and the teal green line represents the faster lap. (Red).

So as we mentioned in turns 5 and 6 the kart is much faster following the yellow line (Blue) than the teal line (Red).  As the kart is begging to enter the turn 6 sector it is going 1.8 mph faster than the teal (red) line. So the instruction to your driver would be to allow the kart to work out wider between turns 5 & 6, stop holding it tight to the radius of the corner. 

If this example had been two different karts (Drivers) your instruction would be to the driver of the red Line would be "Nice job entering turn one, allow the kart to work, stop trying to hold it tight", and your instructions to the driver of the blue line would be "you are applying the brake to hard entering into turn 1, keep pushing the rest of the circuit.". The object is to make your driver(s) aware of what you see. 

As this data came from Abby's practice - you need to expect a driver to try different things, like driving deep into a corner and driving different lines. He/she should then be able to look at the lap time displayed and determine what they should do. By the end of the second round they should be able to run consistent lap times. Give your driver the best opportunity to succeed.

Next up we will be looking at how this device can tell you how well the kart is handling. Yes its that good.
