HOW WOULD YOUR BMW BENEFIT FROM AN EPIC MOTORSPORTS PERFORMANCE CALIBRATION?
Modern engines have come a great distance in a very short amount of time. The combination of new technology and better components, such as, variable valve timing, Valvetronic, and forced induction result in better performance and increased fuel mileage as compared to the same displacement engines only a few years ago. One of the rapidly evolving components is the Engine Control Unit (ECU). Modern ECU’s contain new powerful processors. The processors’ performance is measured in megahertz allowing performance in millions of calculations per second.
All of these advances in performance and fuel mileage are running concurrently with stringent manufacturer emissions standards. These standards are very restrictive in nature; power output is greatly affected as a result. A single vehicle model will sell 100,000+ units worldwide and each unit must meet varying countries’ emission standards. In the US, the EPA requires manufacturers to cover specified major emission control components for the first 8 years or 80,000 miles. A manufacturer cannot risk their reputation or their bottom line if they sell a car that has difficulty passing post-sale emission testing. To meet required standards, a significant margin for error is built into the calibration, which leaves power on the table.
Engine sensors are built to read within certain tolerances. As these sensors age they will often degrade and the reading sent to the ECU will vary slightly. Knowing this, manufacturers err on the conservative side to help avoid emission/warranty issues by building in a margin of error. In addition to building in flexibility for ailing sensors, manufacturers are also forced to consider other wear items either from lack of service or neglect. Old spark plugs, dirty air filters, low grade fuel accidently or intentionally run through the engine are all taken into consideration when calibrated by the manufacturer. As a proponent of performance you wouldn’t do such a thing, right?
When calibrating an engine, manufacturers consider all of the above-mentioned factors , which leads to a conservative end product. OEM calibrations must function in all environments and take in to account countless variables. This means they are restricted when it comes to performance. However, this also leaves great room for improvement when recalibrated in the aftermarket.
At Epic Motorsports, we do not have OEM manufacturer restrictions. As a result, we are able to remap the engine calibration settings and focus more on output. This translates to better drivability, more power output, and often, better fuel economy.
Our performance calibrations will increase a stock engine’s performance. As a car is modified from its stock form, the benefit from remapping becomes increasingly important and more beneficial. As restrictions are removed by adding cold air intakes, exhausts, headers, cams, et cetera, the amount of potential airflow is increased; as a result, the torque curve shifts and the ignition angle, valve timing, and the fuel curve need adjustment. Our performance calibration will maximize the benefit of your aftermarket parts and maintain drivability.
Although manufacturing has become more precise there is still a large enough inconsistency from one engine to another affecting performance. It is simply the nature of manufacturing processes that some engines produce more power than others. We find that although our “off the shelf” calibrations will make sizable gains there is always room for improvement from a custom calibration. This becomes more important and beneficial the more modified an engine becomes.
