Brake Boost is included on all tune stages.
Throttle Mapping
The new generation Audi MG1 ECU uses a complicated mass flow model to calculate boost control. Typical ECU tunes simply raise the wastegate pressure, however, since the maps that control wastegate position (boost) are not controlled by throttle input resulting in limited throttle predictability. To avoid delivering full-boost at half throttle input, IE engineers have taken the care to rescale the entire mass flow model mathematically over 30 maps which correct the entire range of throttle input. This delivers a linear and predictable throttle pedal which improves drivability in every situation on the street or track.
Boost Control
The stock ECU boost control is delivered in a very “close enough” and erratic boost curve. This slow response is reflected in the factory torque curve and can be felt on long power pulls when utilizing the entire powerband. To smooth out this torque curve, IE calibrators re-tuned the boost control mapping to be much faster achieving precision boost request targeting that results in unmatched power delivery.
VE Modelling
The factory 2.9T engine's MG1 ECU relies on a complicated volumetric efficiency (VE) model to convert boost to engine load and accurately deliver fuel for various conditions. Instead of depending on fuel correction tables to compensate, our calibrators have remodeled the VE mapping for the new boost/load relationship. This extensive work delivers reliable and proper fueling and smooth power delivery you can feel.
EGT Optimization
Exhaust Gas Temperature (EGT) is the measurement of fuel mixtures exiting the exhaust and is used to determine the health of the fuel/air mixture entering the engine. IE engineers have spent countless hours adjusting boost air/fuel ratio, ignition timing angle, camshaft phasing, intake air temps, and much more to develop the proper EGT adjustments for ultimate engine safety without sacrificing power on all octanes. Since Ethanol burns cooler than gasoline, the extra fuel left over in the cylinders acts as coolant further reducing combustion temperatures and allows for a leaner air to fuel ratio without dangerous EGT levels. All IE files contain safety measures and complete knock control to keep the engine producing it's potential within verified and safety-first operation.
