![]() ![]() colour code the track map trace with logged data, and.You can create these maps with any GPS data analysis system that allows you to: Gear Ratio Maps In 3 Steps Using AIM Race Studio I will also take you through a worked example to show you how I would interpret the theoretical suggestions verse the track characteristics. In the rest of this article I will show you precisely how I created the gear ratio maps so that you can have a go at them yourself. Want To Create These Gear Ratio Maps Yourself? You can also then see how well you (or your driver) is able to achieve that plan. You will know, for sure, which is the best gear to chose. You can then decide to adopt the recommendation (knowing it is fastest) or consciously decide to take another path (due to the track design or whatever).Įither way you are on the front foot. ![]() If you are unsure whether a corner is 3rd or 4th gear, you can use this method to get a precise answer. The aim, as always with using data, is to use data to help reduce your uncertainty. You can then work out how practical it is (or not!) to get the driver to change what they are doing to go faster. ![]() It also highlights precisely where your driver is not following the theory so you can improve. The great thing is the ideal gear ratio map gives you certainty on what the best gear should be. You need to interpret this recommendation accordingly. What the theory suggests is that if you had an instant, effortless and seamless shifting gear box then you will be fastest in the ideal gears at these points around the track. It does not consider the environment the race car is in – the corners, gradients, time to change gear etc. ![]() This is because the theory considers the car on a pure speed basis. In this example, it shows places where a gear lower might be faster than what he chose. This is the actual gear chosen minus the ideal gear suggestion.Īnywhere there is a colour difference (being pointed at), the driver might enjoy being in another gear. Imagine if you could SEE anywhere that you had opportunities to improve … What would be even better, is if you could somehow use your logged data to automatically show you the best gear choice around the track.Ī clear, simple visualisation of the ideal gear to be in at any point around the track.įurthermore, it would be also super useful somehow use this information to assess how well you were doing at selecting the ideal gears. See The Best Gear Ratio Mapped – Automagically It is ok but slow to do during a track session, ironically when the information could be most valuable. You need to transcribe your velocity curve into the sheet. The advance spreadsheet will show you but it does involve some manual input. What would be great is if you could use your calculations to work out the best gear to be in anywhere around these tracks. The thing is, you likely visit lots of different tracks. You should have a table that will look similar to this: Table 1: Optimum Gear Ratio Shift Points So you have your gearing ratios optimised and you know your best shift points.
