WHAT DOES THE IE AUDI B9 ECU TUNE DO?

Your ECU (Engine Control Module) is a computer loaded with maps to control the operating conditions of your Audi 2.0T engine. The factory calibration is designed to function with stock installed hardware, meet new car regulated standards, and de-powered to not compete with higher performance models. IE's motorsport recalibration brings your engine to life by unleashing its full performance potential on stock hardware or to match your installed hardware upgrades while maintaining reliability and factory-like comfort. This is how your turbocharged Audi should have felt from the factory!

SHIFT FASTER, DRIVE FASTER The IE DSG Tune for your Audi B8/B8.5 S4/S5 3.0T delivers increased power, higher RPM limit, faster shifts, optimized shift points, adjustable launch control and additional transmission performance features when paired with a matching ECU tune. Acceleration times will greatly improve turning your tuned 3.0T into a fully rounded performance monster. LEADING FEATURES Lightning fast gear shifts Higher shift points of 7200 RPM Multiple launch RPMs: 3400, 3600, 3800, 4000 Drive shift mapping entirely reworked with an enthusiast in mind Flashed directly through OBD-II Port (No TCU removal required) Works flawlessly with all IE ECU Tunes Unlimited launches (factory defaults to 200) Increased clutch pressure on tap for higher torque without slip Temperature protection remains for safety Gear hunting reduced Gearbox “Torque Limiters” removed WHAT DOES A DSG TRANSMISSION TUNE DO? IE’s Audi S4 (DL501 S-Tronic) DSG tune is all-inclusive and does not offer expensive upgrades. That’s right, there are no unnecessary upgrade charges and all features and upgrades are included at one low cost. A great deal of sportiness is added to the tune while maintaining factory smoothness and driveability that you love about the S4. More aggressive launches and faster shifts are guaranteed to put a smile on your face. Also, expect acceleration and 0-60 times to improve dramatically from a larger useable powerband provided by the higher shift points. REQUIRED FOR SELECT ECU TUNES Required for S4 & S5 Stage 2 dual pulley files, your new transmission tune will no longer lug the engine in drive mode or short shift the larger powerband. Clutch clamping forces are increased so the transmission can safely handle and deliver the increased power and torque. DSG tune requires a matching ECU Tune, do not install on stock ECU tunes. ONE TUNE FOR ALL STAGES IE’s DSG tunes are all-inclusive without any expensive upgrades. That’s right, there are no unnecessary upgrade charges and all features are included from the outset for any level of hardware or ECU Tune Stage, one cost and you are covered for all and any future upgrades from Stage 1 to Stage 2 billion. USER ADJUSTABLE LAUNCH CONTROL The purchase of an IE DSG file grants you access to customization of launch points. With several launch points to choose from you can pick what works best for your setup! Available Launch Control RPMs: 3400 RPM 3600 RPM 3800 RPM 4000 RPM *Some early model B8 DSG TCUs cannot have launch control added to them, as well as some replacement Mechatronics units. Non compatible TCU codes include, but may not be limited to 8K1927156AC and 8K1927156AD. You can use your IE Powerlink tool to check your TCU code. Other DSG tune features will function normally. IE DSG TUNE TECHNICAL FEATURES HIGHER SHIFT POINTS Utilize the whole powerband of your supercharged 3.0T engine without the DSG interfering and shifting early. DRIVE MAPPING REWORKED The B8 and B8.5 S4 is designed to a fault to keep engine rpm extremely low in drive. We completely reworked this, creating a more enthusiast-friendly drive mapping which shifts a bit higher. This eliminates vibration and that constant feeling that you’re lugging the engine. We’ve reworked the downshifting aspect as well, making the transmission much quicker to deliver power when you need it. Thousands of miles of testing were accumulated and a variety of users were polled to come up with this improved drive mode. INCREASED CLUTCH PRESSURE Increasing the clutch pressure allows for the transmission to hold more torque without causing clutch damage or expedited wear. With the increased torque, the acceleration will be greatly increased and launches will far more aggressive. FLASHED THROUGH OBD-II PORT There’s no need to remove the TCU from the car and it can be flashed in your driveway or through an IE software dealer. Additionally, having an IE PowerLink cables means you can install updates are they become available as well as read TCU and ECU fault codes. TAKE-OFF LAG REDUCED The clutch engagement has been reworked to reduce that annoying “DSG Lag” when moving away from a stop. MULTIPLE LAUNCH RPMS The purchase of an IE DSG file grants you access to customization of launch points. With several launch points to choose from you can pick what works best for your setup! FLAWLESS OPERATION WITH IE ECU TUNES The IE DSG Tune and ECU Tunes were developed side by side on our in-house dynamometer. By running both tunes you will unlock the full potential of your 3.0T engine and transmission. Perfect for all IE Tunes from Stage 1 to dual pulley and throttle upgrades.
