1. What type of lab scope do I need to use the FirstLook sensor?
PicoScope automotive oscilloscopes are ideally suited for use with the FirstLook sensor, however, most other modern dual-trace lab scopes will also work with this sensor. The lab scope needs to have the ability to trigger and cursors for pattern measurement. The triggering allow you to get cylinder specific information as it relates to a specific event in the engine, for example, the firing of number one spark plug. The cursors allow you to dissect the pattern and find which cylinder has the problem.
2. What information can the FirstLook sensor give me?
The FirstLook sensor can look at valve operation, cylinder efficiency, fuel injector operation, and overall engine operation.
3. Why is the information the FirstLook sensor gives important to diagnostics?
All the information gathered by the FirstLook is the same information the vehicle computer looks at to make changes in performance of the engine. If the base engine functions are not in proper order, the computer in the vehicle can give erroneous information and false diagnostic trouble codes which can result in wasted time and money. In short, if the base engine functions are not in proper working order all information given by the computer is tainted.
