Our affordable 20 channel DataMite III USB or smaller DataMite Mini USB can computerize your dynamometer for improved accuracy and time savings. You can watch "real time" gauges as you run the engine, make color torque and HP graphs and print them in color with a color printer, overlay 2 or more graphs for comparisons, save nearly an unlimited number of runs for retrieval in the future, make reports and averages over most any RPM range and much more. We've instrumented over 400 dynos, from small RC engines using 7" diameter inertia wheels, to inertia dynos running 2500 HP blown alcohol motors. We've retrofitted Clayton (tm) chassis dynamometers, Go Power (tm) and Stuska (tm) engine dynos, and hundreds of other custom, home built and DIY dynos. If you've got a dyno of any type, we can add instrumentation to give you accurate and professional results. for some pictures of our customer's dynos. Performance Trends has been doing racing software since 1986, so we know what engine builders need and how to make it easy. You’ll be amazed to find all the powerful, yet "easy-to-use" features in our software, and surprised that we can still keep our costs so low. From a simple system recording just RPM/torque/HP up to a complete system recording fuel pressure, fuel flow, oil pressure, A/F ratio, 8 exhaust temperatures, weather conditions and more; Performance Trends can supply the complete package. You can tune your engines by measuring additional inputs, like fuel flow, air flow, oil or fuel pressure and A/F. Setting A/F (air to fuel ratio or how rich the engine is running) is critical to obtaining peak performance. A/F can now be inexpensively added to most any dyno, even small Kart dynos, because of the tremendous advances with wide band oxygen sensors. See picture below.
