Integrated Engineering Performance ECU Flash - Audi A4/S4/RS4 B9 / A5/S5/RS5 B9

Integrated Engineering's performance ECU software rewrites the factory engine calibration to unlock power the standard tune leaves on the table. IE develop each calibration on their own vehicles and dynos, tuning boost, fuelling and timing together rather than simply raising boost, so the result is stronger throughout the rev range while keeping factory safety systems intact.

Features

• Calibration developed and validated on IE's own test vehicles
• Boost, fuelling and ignition timing tuned together
• Factory safety and diagnostic systems retained
• Flashed via OBDII - no engine hardware changes required
• Reversible to the stock calibration

Specifications

• Brand: Integrated Engineering
• Product Type: ECU Flash
• Part Number: IESOVZ14

Vehicle Compatibility

• IE calibrators spent many months developing and testing ethanol blends on the B9 3.0T engines in many climates and elevations. Results were consistent that full E85 runs very close to or beyond the limit of the factory direct injection (DI) fuel system in the mid-range but allows for more power up top. IE's E85 calibration keeps mid-range power in check to avoid lean conditions, misfires, and power loss then ramps it up top for amazingly fast and consistent track times in a drag racing scenario. E85 is also great for easy fill-ups at the pump for daily driving without mixing blends.
