UTV Performance Chips

Since electronics mainly superseded carburetors, vehicle manufacturers have benefitted from much greater flexibility in adjusting the engine and improving its operation in different conditions. It became possible thanks to a more precise proportion of air and fuel in the mixture and its quantity, more accurate ignition timing, and sophisticated diagnostic tools showing current performance under various loads. All the processes now are monitored and managed by the engine control unit (ECU) which relies on several sensors and special maps developed after many hours of testing on dyno stands and tracks.

Finally, the results of this important work appear in the aftermarket, and various companies develop their own solutions geared toward improved performance. In fact, “optimal engine operation” implies different things depending on the application. For instance, for most utility terrain vehicles, low-end torque is more preferable than maximum power at those revs you actually never reach. This benefit and other improvements can be achieved with the help of aftermarket tuners, programmers, fuel management systems, and data loggers allowing you to set, check, and analyze all of the crucial parameters.

A vast array of these products can be found on our virtual shelves. Created by professionals, they offer all the features allowing you to tune the motor in the most effective manner. We carry controllers coming with wideband oxygen sensors that enable you to precisely adjust the air-fuel ratio in different RPM zones and avoid running on a lean mixture. Also, there are models enabling you to alter ignition timing according to engine temperature or other factors. Some products operate together with the stock ECU and allow you to change its settings with or without an additional PC; others can replace the factory module and provide you with powerful tools needed to tune a modified motor. Using a data logger or similar device, you can carefully analyze your vehicle’s behavior from the comfort of your home comparing the data of various sensors shown in a convenient form.
