TechnoMotive Datalogger Information
Have you ever wondered what your car's computer is thinking while it controls the engine? The TechnoMotive Datalogger allows you see the internal workings of the ECU, or Engine Control Unit. Plug one end of the special adapter cable into your car's diagnostic port and the other end into your laptop, select the data type or types you are interested in, and start driving. The amount of data you can collect is limited only by your laptop's hard drive capacity.
Ever seen a mechanic plug a handheld computer into a car while you had your car in for service? Anything that a mechanic can do with the factory diagnostic unit you can do with the TechnoMotive Datalogger , but also much, much more. Not only can you see a display of the current sensor and actuator values, you can also plot the values on a live scrolling chart. In addition, you can save a continuous stream of data to your laptop's hard drive for later analysis.
The TechnoMotive Datalogger makes a great diagnostic tool. Tracking down faulty or intermittent sensors using a voltmeter can be very frustrating and time consuming. Most of the time you cannot check sensor values when the engine is running or even if you can, how can you be sure the ECU doesn't have a bad connection somewhere deep in the wiring harness? The TechnoMotive Datalogger lets you see exactly what the ECU is seeing.
The Datalogger also allows you to shut off one injector at a time even while the engine is running! This enables you to easily perform a cylinder balance test. You can also actuate all the solenoids as well as cycle the fuel pump relay. Engine tuning is where the TechnoMotive Datalogger really shines. How much is timing being retarded at wide open throttle? Or am I getting a lot of knock around 5000 RPM? The TechnoMotive Datalogger can answer these questions, and more. It is often difficult for home mechanics to tune their cars. Most of the time, the only tools that are available are an oxygen sensor meter and the seat of their pants. Using just these tools, they could never be certain that what they had done to the car was fully optimized unlessthey paid for expensive time on a dyno. The TechnoMotive Datalogger provides an economical alternative to dyno testing. You will be amazed at all you can do with your TechnoMotive Datalogger, as will all your friends!
