With the high cost of fuel today, it’s worth your while to maximize every drop when you need higher levels of performance or economy for your truck. Not only does the Evolution HT hand-held tuner do just that, but it also doubles as a diagnostic scanner to read fault codes and engine running conditions in real-time. If you have any pre-existing check engine conditions, the EVoHT will give you a full diagnosis of why your light is on with no extra cost. You’ll keep more money in your pocket instead of giving it to oil companies and technicians. After plugging into your OBD II port, the EVoHT first store's factory settings for air and fuel mixtures, fuel injector flow rates, timing, throttle response speed, automatic transmission shift points and more should you wish to return to OEM specification. Next, you can download software specifically created for your vehicle tailored to provide an astonishing increase in horsepower for higher on-road performance or towing or choose your own preferences for throttle response and transmission shift points. During everyday driving, a fuel economy setting maximizes all parameters for improved mileage.
Factory engineers created your vehicle to operate under the extremes of a wide variety of conditions but ultimately settled on one range of midrange settings to satisfy the everyday driving needs of most vehicle owners. Because those common denominator algorithms do not maximize any specific performance category, the EVoHT tuner simply adjusts factory settings to get the most out of your engine’s natural abilities. Vehicle emissions will remain legal in 50 states no matter what setting is selected. If you’ve got large tires on your truck, just let the EVoHT know what size they are and it will adjust your speedometer and odometer to read correctly again. Because tires with a larger circumference effectively change overall gearing ratio from the engine to the pavement, the tuner can adjust throttle response and transmission shift points at just the levels and speeds you’ll need in order to reduce sluggishness and improve drivability.
