What is the distinction between a Performance and an Economy Remap?

First and foremost, we’d want to explain what ECU Remapping is. ECU Remapping is a customized software configuration that is swapped with the original ECU software to boost power, torque, and, in certain situations, fuel consumption. Remap prepares the car to reach maximum efficiency in the safest way possible. As you may know, the ECU entirely controls the automobile engine, thus remap the ECU will have substantial impacts on acceleration, fuel consumption, engine knock, and so on.

Remapping involves remapping the tables in the car’s ECU, and depending on the software of your car’s ECU, the ECU will be full with mappings for various things such as Spark Advance, Lambda, and so on. In truth, everything has been done individually, and we program remaps on purpose to meet the unique demands of each vehicle. The precise results will be determined based on the make, model, and year of your vehicle.

What exactly are Engine Maps?

We hear a lot about Engine Maps and modes, which Tuners frequently adjust and experiment with, either independently or at the request of their engineers. So we’d want to learn more about Engine maps and how they effect how automobiles function. Let’s start with the fundamentals. Previously, the accelerator pedal was physically attached to the engine throttle by a mechanical connection. The more you pressed your foot on the pedal, the more the throttle opened, allowing more air and fuel into the engine cylinders, causing the engine to produce greater power through higher combustion.

It was simple, but it had limitations. The amount of travel in the accelerator pedal is now electronically monitored and read by the “Electronic Control Unit” or ECU. The ECU then processes a slew of additional data from the vehicle to determine how to best regulate the engine’s combustion and, ultimately, power production. All of this is accomplished through the use of Engine Maps. Engine Maps are simply a collection of data tables in which the ECU examines what’s going on with the automobile and driver inputs to determine what to do with the engine.

To gain a sense of this, start with the Engine Torque Map, which is more of a map than a set of instructions, but it all fits into the bigger picture. The Engine Torque Map simply states how much torque the engine produces as normal at a given RPM and throttle setting. The RPM (engine rotational speed) and throttle level (essentially, how much fuel mixture you’re pouring into the engine) are your inputs. The torque (just how much turning force the engine produces) is an output. The chart will give you the engine torque if you know your RPM and throttle level.

So, consider a simplified scaled-down version of this Engine Map. We could simulate it to see what happens at slow, medium, and rapid RPMs. We may also examine the narrow, medium, and full throttle levels.

This produces a lovely table with nine alternative possibilities as outputs. So, if the engine is operating at low RPM and we’re only lightly pressing the throttle, the map predicts that the engine will produce a modest amount of torque. Full throttle at high RPM generates a lot of torque, and so on. Obviously, real-world Engine Maps are much more detailed than that, since they require more than just our three gradations of input. As a result, this Engine Torque Map just represents the engine’s regular behavior. We may get this information by running the engine on a testing Dyno and monitoring its torque levels in various conditions.

But what if we wanted to construct a map that behaved differently than usual?

In this regard, a Performance Remap differs from an Economy Remap. This is where our unique engine maps come in. We may modify these maps such that when a driver presses the accelerator pedal at a specific engine speed, the torque production varies depending on the Map. Actually, it is determined by the demands of the consumer. For example, if we wish to enhance fuel usage, we could want to raise the Air/Fuel ratio at lower REVs. Because the consumer does not require the engine’s maximum power.

We term it “Economy Remapping” in the tuning industry. To get the most out of the engine, we may want to make the transition from low to high torque more dramatic or reduce the Air/Fuel ratio. That’s what “Performance Remapping” is all about.
The concept behind these maps is that we will require a specific level of torque or power from the engine based on certain conditions. We’ll instruct the engine that if I press the throttle halfway and you’re revving at 8000 RPM, you should give me 180 Newton Meters of torque or whatever.

Assume you are the driver, and when you adjust the pedal with your foot, you will have an expectation of what the engine will perform and how much power will be transferred to the wheels.
According to the guidelines, 0% and 100% throttle degrees must correspond to 0% and 100% of available torque, respectively. So, 50% throttle creates 50% torque, 27% throttle produces 27% torque, and so on. “That makes sense,” you would think. That would be really natural to me as a driver. I’d be able to pinpoint my exact location. But consider this: accelerating out of a slow bend requires extreme caution to avoid wheel spin.

It slows you down and wears out your tires. This happens when you apply too much torque to the tires. As a tuner, you may like the pedal to be more sensitive at initially. Each centimeter of pedal movement results in a smaller change in torque. As a result, you can control a gradual rise in torque at lower speeds more precisely.
As a result, the Engine Map would initially have a shallower graph. Perhaps the first 30% of the pedal provides just 10% of the engine torque. This is one of the circumstances that contribute to the driver demand torque maps.

Examples of various Engine Maps scenarios:

Rainy weather

High elevation

High relative humidity

Saving Qualifying Power

Slow turns

Rapid speeds

Finally, you must remap the automobile to meet the wants of your consumers. If they desire an Economy Remap, you must change all of the tables accordingly. On the other hand, if they want to enhance the power and get the most out of the engine, they must make adjustments in all of those tables. This is referred to as a Performance Remap.
