![]() Just like tuning a musical instrument, the ECU includes a number of parameters that must be synchronized.ĮCU tuning will allow you to unlock the hidden potential of your vehicle. Many drivers don’t even know that the ECU exists, let alone that it can be modified for optimal performance.ĮCU Tuning is about getting the right combination of variables for peak engine performance. ![]() LOW-PRICED ECU TUNINGS.Īnd indeed, for the average consumer, the factory ECU map is perfectly fine. The manufacturer of the vehicle has no idea what particular customer will buy the car or where they will drive it, so a generalized, jack-of-all-trades ECU tuning is the most logical choice.ĬLICK HERE FOR A VIDEO ANALYSIS AND PRICE COMPARISON OF HIGH- VS. In the U.S., for example, a conservative ECU map is calibrated for average weather and road conditions in North America, with a mix of highway driving and in-town driving in mind.įrom a sales perspective, this makes perfect sense. It’s sort of like waving a magic wand to unlock your car’s hidden potential.Įngine manufacturers use a so-called “conservative” ECU map that is designed to accommodate as many different kinds of drivers as possible. What’s the Point of ECU Tuning?įor as long as cars have existed, people have wanted them to go faster and run more efficiently. Whether you live in the heartland, the deep south, Texas (they hate it when you call them the “deep south”) or the coasts, you can get a professional-grade ECU tune up for your vehicle at a reasonable price. In this article we’ll look at some of the best ECU tuning shops from around the country. ECU tuning allows you to optimize your vehicle’s performance in a number of different areas, from fuel efficiency to increased power output or even better emissions standards.Ī Fabspeed ECU upgrade chip for the Ferrari 488. Averaging ramp-up and ramp-down power pulls removes the inertia of the dynamometers rollers from the reading.ECU tuning, also known as “chip tuning,” refers to the process of reprogramming a vehicle’s electronic control unit or ECU. When the engine redline is reached, the test may be completed or a switch on the controller may be flicked, causing the dyno to ramp the engine back down. Flicking a switch allows the dyno to ramp up in speed.Īs the engine rpm increases, the dyna’s software draws a trace on a PC screen, showing the power being developed. The tuner instructs the dyno as to the type of test being undertaken holds the low rpm in the selected gear and then gives the engine maximum throttle. ![]() Very powerful cars are therefore sometimes tested in higher gears, although second gear is most commonly used. The higher the gear, the lower the tractive effort trying to pull the car of the dyno. Any gear can be used, but second, third or fourth gears are usually selected. The ‘ramp speed’ (rate at which the dynamometer lets the engine speed increase) is set and the car is run at very low rpm in the selected gear. The dyno tuner controls speed and other factors via a hand-held pendant that contains controls for load. The steering wheel does not need to be touched. The dyna tuner sits in the driver’s seat and operates the accelerator, clutch and brake. A large fan is placed at the front of the car to cool the radiator and any other heat exchangers located there. Front-wheel drive cars tend to be more unstable on dynas than rear-wheel drive cars, so when dynotuning FWD cars, small “trainer wheels” are locked into place on either sides of the front wheels. On a 4 wheel drive chassis dyno, the distance between the front and the rear sets of rollers can be changed to cater for dyno tuning different wheel-based cars. The car is strapped down so it cannot move laterally or longitudinally, with non-driving wheels choked on 2 wheel drive dynamometers. Dyna tuners all differ with their output figures but how it works is the same. The car is driven onto the dyno so that the drive wheels rest on the rollers. A chassis dyno is equiped with large rollers, usually sunk into a pit.
