What is Woolich Racing AutoTune?
Woolich Racing AutoTune is a feature currently available in the Woolich Racing Tuned software. AutoTune works with data logged either from the Engine Data Screen or when using the Woolich Racing Log Box. The logged data is sorted and analyzed and changes are provided which will bring the Air Fuel Ratio (AFR) of your bike closer to the Target AFR. The AutoTune process involves the following steps. Data Logging Review Logged Data in the Woolich Racing Tuned Software. Apply suggested changes to the Fuel Maps Write changes to the ECU Repeat from step 1 until you have reached your Target AFR and the suggested changes are small. AutoTune allows you to tune both IAP and TPS maps.

Wheel Speed Adjustment and Correction
Most modern motorcycles measure the rotation of both front and rear wheels and use this to calculate the speed that the motorcycle is travelling. The speed calculation depends on the size of the wheel and tyre and if the wheels or tyres are changed then the speed calculation may no longer be correct. In these cases it is useful to adjust the speed calculation and some motorcycle ECUs allows for this by using a correction factor as shown below for a Yamaha 2020-2023 YZF-R1. These factors are multiplied by the rotation frequency to calculate the speed. Bigger tyres have bigger factors and therefore higher speed if rotating at the same frequency. If your new tyres have a circumference which is 10% larger than the current ones, the factor will need to be increased by 10%. If the circumference of the new tyres are 5% smaller then the factor will need to be reduced by 5%. If the tyres are changed on the bike then it is necessary to calculate the circumference (not the radius or diameter) of the new and old tyres. These are then used to calculate a percentage change in the circumference and this is then applied to the current correction factor(s). The circumference of the tyre can be measured directly using a tape measure or a piece of string etc, alternatively it can be calculated if the tyre dimensions are known as shown below. The following example shows how to calculate the tyre circumference for a YZF-R1: YZF-R1 Stock Standard Tyres: Front: 120/70-17: Nominal width = 120mm Aspect ratio = 70%, this means that sidewall height = 70% of nominal width = 0.7 x 120 = 84 mm Diameter of tyre inner rim = 17 inches = 431.8 mm Tyre outside radius = 431.8/2 + 84 = 299.9 mm Tyre diameter = 431.8 + (84 x 2) = 599.8 mm Circumference = 2 x pi x r = pi x d = 1884.3 Rear : 190/55-17: Nominal width = 190mm Aspect ration = 55%, this means that sidewall height = 55% of nominal width = 0.55 x 190 = 104.5 mm Diameter of tyre inner rim = 17 inches = 431.8 mm Tyre outside radius = 431.8/2 + 104.5 = 320.4 mm Tyre diameter = 431.8 + (104.5 x 2) = 640.8 mm Circumference = 2 x pi x r = pi x d = 2013.1 As circumference = pi x d, we only need to know the increase in total diameter to calculate the correct factor for different tyres. If the tyre diameter increases by 5% then the correction factor should be increased by 5% also. These Support Center articles may also be of interest to you: What is ECU Flashing?

Idle Speed Adjustment for Early Model Yamaha YZF-R1/R6
Most modern motorcycles use an ECU (Engine Control Unit) to control all engine parameters including the idle speed (RPM). The Woolich Racing Tuned software allows us modify the bin file used by the ECU and thereby modify specific parameters, including the idle RPM on most supported motorcycle models. Many recent models of motorcycle like the 2020-2023 Yamaha YZF-R1 series allow for the idle speed to be controlled directly by setting a numerical value in the ‘Advanced Settings’ of the Woolich Racing Tuned software as shown below: Earlier Yamaha YZF-R series models (eg. -R1, -R3, -R6) did not allow direct control of the idle RPM but did allow modification via specific changes made to certain maps. This article explains how to modify the Idle RPM of these models by changing the available maps. The examples provided below show screenshots of the Woolich Racing Tuned software using the 2006-2007 Yamaha YZF-R6 as an example. The idle speed of other early model YZF-R models will use similar changes however the capabilities will vary slightly from model to model. In general there are three ways to control the idle speed of the 2006-2007 Yamaha YZF-R6. The first method is to apply the ‘Gear Idle’ speed to all gears, this idle is significantly higher than the idle speed when in neutral. The second method is to make adjustments to the map ‘Coolant Temperature Idle Compensation’ which is found under the ‘Other Maps’ of the Woolich Racing Tuned software. This map allows modification of the idle speed based on the engine temperature as the bike is warming up. Note that when the bike is warm the values in the right-hand column will be used. In this map the column headers show temperature and the row headers show the nominal engine RPM. The values in the cells are the set RPM values divided by 100, ie. a value of 12.5 indicates 1250 RPM. This can be particularly useful for colder climates where the engine can run ‘rough’ when trying to start at very low temperatures. The third method to adjust the idle RPM is to modify the ignition timing in the idle region, ie. at low RPM and low throttle (TPS). Making small increases to the ignition advance (BTDC) to the lower left corner of this map will result in an increase in idle RPM. Please note that small changes here of only 1 or 2 degrees should be made and tested by writing to the ECU and running the engine before making further changes are made. ie. small changes in the ignition timing do result in significant changes in engine speed (RPM).
