The Power of GPS

The Power of GPS

In the past datalogging was something only reserved for the top teams competing in world championships and still today it can be quite an expense to get similar equipment fitted to your bike. Luckily we have companies like AIM, Starlane, Motec and many others trying to help riders through datalogging for as small a cost as possible. One of the best solutions on the market is the AIM Solo and Solo DL.
With AIM you can choose the Solo or Solo DL. The Solo is a GPS laptimer that lets you plug in your computer after to view your data lap by lap. You can compare each lap and see where you're gaining or loosing time. The Solo DL lets you go one step further by connecting your bikes ECU and logging values like RPM, wheel speeds and throttle position while tagged with GPS locations.

Some possibilities with GPS data

Compare Laps & Sectors
Naturally since the Solo's are laptimers you can easily see all your laptimes, but it's also possible to go into much more detail! In one click of a button in the AIM analysis software you can view your sector times, your best time, best ideal time made up of all your best sectors and your best rolling laptime. The best rolling laptime is much more interesting than the best ideal time. The rolling time is your best time of a complete lap but not necessarily from start line to finish line. Your best rolling lap might be from turn 4 back to turn 4 again but the important thing is unlike the ideal time which is made up of a mix of laps the rolling lap is one complete lap.

Sector Times

Once you start to look at any data you can easily overlay more than one lap to see what is making a difference to your laptime. In the image below the graph is showing two laps and the throttle position. If you look at the bottom of the graph the second graph is showing how much time you madeup or lost and this is where you can start to see what is actually making a difference to your laptimes

Time Delta

View lines driven
We all know how important your racing line is so what better way to view your racing lines than overlayed on google maps.


View braking points
On the graph below you can see two places I've marked with a red circle. This is the braking point for a rider shown on the track map and corresponding graph. It's very easy to go through the graph and view exactly when and how hard the rider is braking just from GPS data.

Brake Point

Times between accelerating & braking
The graph below shows the time it took for a rider to go from throttle to brake. In this case the rider took approx 2 seconds at the end of a straight. This is an area the rider worked hard on improving all around the track and was able to make a dramatic change to their laptime.

Delta Brake


Connecting your datalogger to your bikes ECU opens up even more possibilities to analyise yours and the bikes performance. With modern bikes getting more and more reliant on electronics and traction control you can use the Solo DL to help maximise the performance of all your modern electronics.

With the RPM you can make sure you have your gearing setup perfectly for each track without having to waste time testing a lot of different setups. The graph below is one of many you can use to help choose which gearing to use. In this graph you can see each individual gear and the speed range of each gear.


Throttle Position
Throttle position is a channel you can have lots of fun with and display it in many ways. The image below shows a riders throttle position overlayed on a map. I have circled an area where you can see the rider momentarily role off the throttle as they lift themselves back onto the bike while exiting a corner. These are small things you can look at to save a lot of time but this is just the basics of throttle position analysis and you can find a lot more about time a rider may be loosing by going deeper into different ways of using the values in this channel.


Traction Control setup parameters
Below there are two graphs. The first one shows the level of tyre slip a bike is having over the course of a lap. Here we measure the difference between front and rear wheel speed and display it as a percentage difference.

Tyre Slip

This graph shows how we trigger different traction control events based on several variables, one of these is tyre slip. The colour highlighting is the amount of tyre slip and the numbers you see are different levels of traction control events. The traction control events can go from 1 to 15.
