Hello dmo,
ShockWiz can be moved around and used on as many suspension products as you like, given that the suspension you're installing it on is compatible.
In order to use ShockWiz it must be calibrated to the fork or shock it is installed on in order to properly analyse your suspension's performance. The calibration process requires that the compression ratio and the baseline air pressure be set. In most cases you will not know your air springs compression ratio, so this will need to be measured. The ShockWiz app features a Calibration Wizard that walks you through this process step by step.
Once calibrated, its ready to use and you can go for a ride. While riding the device measures the pressure of the positive air chamber 100x a second, runs the data through the ShockWiz Algorithm, and outputs easy to understand tuning Suggestions.
The data captured by ShockWiz stores on the device, not within the app, meaning it;s not required to ride with your phone. The data can be accessed at anytime by connecting to the App, and will not be erased until you select "Start New Session" within the app.
ShockWiz devices cannot communicate with one another and using one ShockWiz, and swapping it between the front and rear suspension, is no less effective than using two simultaneously. The only disadvantage of using one device is the added time in tuning the fork and shock individually.
When using a single device to tune a full suspension bike, install and calibrate ShockWiz to the fork or shock and go ride. It does not matter which is tuned first, the end result will be the same. Using the iterative tuning process, keep ShockWiz installed until you are satisfied with the Shock Tuning Score and feel of that suspension component. Then, install and calibrate ShockWiz to the other suspension component and again, keep ShockWiz installed until you are satisfied with the Shock Tuning Score and feel of that suspension component.
As a general note, it is always recommended that you record the settings of your suspension before removing ShockWiz. This includes; Baseline Air Pressure, Number of tokens/ bands installed, and all current damper setting positions. These settings cannot be stored in the App, and it is recommend that a page for each component be created in your phone or tablets "Notes" app.
