Q: What is a Remap?

A: Most vehicles since the late 90′s have now got an Engine Control Unit(ECU for short). The ECU’s purpose is to control how the engine runs, and make sure everything happens at the right time and make sure everything is running optimum. It does this by reading values from a multitude of sensors in the engine bay, looking up the data using multidimensional maps inside the ECU then adjusting the engine components (Turbo pressure, Injectors, Ignition timing etc etc) accordingly. When remapping we look at these tables used to control the engine and we advance them, meaning the vehicle creates more power and will generate better economy. Also a remap means you have no extra wires from tuning boxes, and all safety limits are still intact and working, as the ECU still has full control over the car.

 

Q: Why don’t manufacturers do it?

A: When manufacturers design a car, it has to take into account for all purposes all over the world. Some of the following are reasons as to why the manufacturers have to comprise in power: Climate, Humidity, Different Grades of fuel, and Different Altitudes.

Q: How do you remap without a dyno?

A: A dyno is a tool to use that lets you run the car up the rev range on the spot without having to drive up the road. We use diagnostic tools and fueling (AFR) tools that let us record data as you drive along to give us just what we need to make adjustments to the map and get it dialed in and running perfect without a dyno. PD Tuning can carefully monitor the AFR readings, Ignition timing, Knock, Boost (on turbo charged cars), engine load, airflow meter Flow readings, injector duty cycle and more to make sure the car is running as best as possible with the remapped software on the car.
