The AccessPORT is the industry leading OEM ECU flashing, managing and monitoring assistant. Unlock power hidden within the ECU by replacing conservative factory settings with more aggressive calibrations. The result is impressive gains in torque and horsepower while maintaining a high degree of safety. The AccessPORT comes with pre-installed maps that are optimized for common performance modifications.
ESS N52B30 ESS DirectFlash Performance ECU software is a result of extensive testing and exact calibration of ECU parameters to allow considerable performance gains on an otherwise stock car.
ESS E-Flash N54 ECU software is a result of extensive testing and exact calibration of ECU parameters to allow conservative performance gains on an otherwise stock car.
ESS N55 ECU software is a result of extensive testing and exact calibration of ECU parameters to allow conservative performance gains on an otherwise stock car.
ESS DirectFlash Normal Aspiration optimized ECU software is a result of 100's of dyno runs and exact calibration of all parameters to allow maximum performance gains with improved driveability/fuel consumption and stock engine longevity.
Newly released GIAC performance software for the 2001-2006 e46 M3 w/ VF-Engineering or K&N Cold Air Intake smoothly delivers a 3-25whp and 10-20 ft/lbs gain in torque.
Can be performed in-house at Tunerworks without having to ship ECU out for programming.
For optimum performance, the software must be coupled with VF-Engineering or K&N Cold Air Intake (Specific files for each intake, other intakes may not be compatible)
