AccessECU's StreetTUNER upgrade for the AccessPORT is for enthusiasts who want the ability to “tweak” their mapping. The StreetTUNER software runs on a PC-compatible computer to allow for end-user programming of the factory ECU.

Featuring Live Tuning Technology

A key unique feature of the AccessPORT StreetTUNER is the LIVE TUNING feature that allows real time tuning of the fuel, ignition timing, and boost settings while the vehicle is running. This allows the tuner the ability to test changes before committing to a reflash of the ECU. The time saved alone with this feature is worth every penny.

The StreetTUNER package includes PC-Compatible software that allows AccessPORT owners the ability of tuning the following parameters:

Fuel control Direct control of fuel programming within ECU for precise control.

Closed Loop Fuel control Control exactly when Closed Loop Fueling is active according to RPM, TPS, Boost, Vehicle speed and more.

Ignition Advance control Direct control of Ignition Timing (spark advance). Includes additional "auto-tuning" Timing Advance capability that increases Ignition Timing according to detected knock.

Closed Loop Boost Control Tune for the factory or larger aftermarket turbochargers. Advanced boost control according to RPM and TPS. Uses actual boost values (in psi/bar) as targets. Gain adjustments provided to control spool up speed and stability. Additional adjustments can be made to compensate for Air Temperature and Barometric pressure which allow you to prevent boost spiking on cold days or unstable boost at higher altitudes.

Intake Camshaft VVT Control Control the Intake Camshaft Timing advance as part of the Variable Valve Timing system. Modify to decrease turbo spool-up time, particular when using larger turbochargers.

Fuel Injector Control Tune for larger injectors using a single injector size value. Additional compensations for injector's latency (dead time) and throttle pump (tip-in enrichment) can also be fully controlled.

Intake Calibration Tune for aftermarket intakes and bigger MAF housings that are designed for higher airflow. Complete adjustment can be made to re-calibrate the ECU to understand the increased flow.

Adjustable Rev Limits Engine RPM rev limit can be adjusted to any value between 0 and 10,000 RPM. Adjustment may also be made to control how hard/soft the limiter acts.

Boost Limit Control Protect the engine from overboosting. Multiple boost values can be set, according to altitude, to briefly cut power to the engine in the event boost exceeds safe values.

Turn on/off DTC (Check Engine Lights) Individually select DTC (Check Engine Light codes) you wish to activate/deactivate. Ideal when modifying the exhaust system, etc. Turn off only the DTCs you no longer want to see while maintaining full functionality of the trouble codes you'd want to see (ie: when a REAL problem exists).

Other Software Features The StreetTUNER allows users the ability to Save and SHARE their files with other StreetTUNER users. Files can be saved in both StreetTUNER BASE MAP and REAL TIME formats. Various Staged and convenience Base Maps are also provided.

To assist in the task of tuning, the StreetTUNER software features LIVE TRACING mode, where the area of the table currently being accessed by the ECU will be highlighted for quick and easy adjustments.

In addition, a powerful Data Logging feature is built in that allows high-speed logging of engine parameters and knock activity. In addition, external Air/Fuel Ratio monitors such as the Innovate! LM-1, LC-1 and the Zeitronic ZT-2 are supported and can be logged from within StreetTUNER. An integrated Log Viewer allows you to instantly view your log files from within StreetTUNER.

Package includes StreetTUNER CD-ROM that includes software and map files, a USB security HASP key, and a printed User's Guide. An AccessPORT is REQUIRED to use software.

If your computer does not have a USB port, please inform us at the time you place your order. A Pass-thru Parallel port HASP key may be substituted at no additional cost when placing your order.
