COBB Tuning is pleased to announce the beta release of the AccessPORT and AccessTUNER Race software with full forced induction tuning for the 8th gen Honda Civic Si with the option of using either MAF or Speed Density tuning (MAP) logic. Tuning enhancements such as Speed Density logic, injector scaling, expanded tables, LTFT control sensitivity, advanced throttle tuning, decel. fuel cut tuning, VTC tuning, additional ECU logic toggles and many more give the tuner significantly more control than ever before. The AccessPORT now offers the highest resolution of any OEM ECU tuning solution available, and equal tuning capability for both MAF and Speed Density engine management!

Here are some high points of the new software enhancements:

NEW VOLUMETRIC EFFICIENCY TABLES (MAP) – 10 new 24×24 volumetric efficiency tables with adjustable break points plus a 5×5 cranking volumetric efficiency table for MAP tuning.

FUEL INJECTOR TUNING – Injector scalar table adjustable by cc/min and a 1×5 injector latency table for tuning with upgraded injectors, both MAF and MAP.

IGNITION TABLES EXPANDED – 10 ignition advance tables expanded to 24×24 for increased resolution and ignition coil dwell time table added, both MAF and MAP.

KNOCK SENSITIVY TABLES EXPANDED – 10 knock sensitivity tables expanded to 24×24 for increased resolution, both MAF and MAP.

NEW FUEL COMPENSATION TABLES – Compensatory tables for intake air temperature (four tables) and engine coolant temperature (three tables), both MAF and MAP.

NEW IGNITION COMPENSATION TABLES – Compensatory tables for intake air temperature (five tables) and coolant temperature (four tables), both MAF and MAP.

NEW DECEL. FUEL CUT TABLES – 10 tables to control fuel cut and fuel cut delay to precisely tune rev-hang, both MAF and MAP. Includes gear based, during shift, min speed, max speed, high VTEC and low VTEC tables.

NEW RADIATOR FAN CONTROL – Two 1×2 tables to specify temperature to turn fans on and turn fans off, both MAF and MAP.

NEW THROTTLE CONTROL TABLES – 10 throttle control tables, both MAF and MAP. Includes target angle, APP vs. speed transfer, gear based response entry speed, gear based response exit speed, max target angle, gear based response and several more. Tune the throttle to do exactly what you want.

NEW LTFT CONTROL TABLES – 8 tables to control LTFT sensitivity, both MAF and MAP. These tables control how long it takes after start before LTFT becomes active, allows min and max RPM to be set for LTFT to be active, allows min coolant temp to be set for LTFT to be active, allows min intake air temp to be set before LTFT is active, control rate of LTFT learning and controls the limits of LTFT and STFT adjustments.

NEW CLOSED LOOP MAP THRESHOLD TABLE – Table that allows the MAP sensor to be configured to switch from closed loop to open loop, both MAF and MAP.

NEW CLOSED LOOP TPS THRESHOLD TABLES – Two tables that configure the TPS sensor to switch from closed loop to open loop and reenter from open loop to closed loop, both MAF and MAP.

VTC TABLE EXPANSION – 3D VTC table for closed loop control (expanded to 24×24) and 2D table for open loop control. Also provides the ability to turn off open loop (VTC) to stay in 3D table, both MAF and MAP.

NEW MAF SENSOR COMPENSATION TABLES – Compensatory tables for Barometric pressure and intake air temperature, MAF only.

NEW SPEED ADJUSTMENT TABLES – Two tables that allow the speed output to be changed to the speedometer and ECU separately, both MAF and MAP.

NEW MAP VS. TPS SWITCHING TOGGLE – This toggle allows the user to select the MAP sensor or the TPS sensor to determine open loop/closed loop switching, both MAF and MAP.

NEW 2ND COOLANT TEMP TOGGLE – Allows 2nd coolant temp sensor to be toggled on/off, both MAF and MAP.

NEW KNOCK SENSOR TOGGLE – Allows knock sensor to be toggled on/off, both MAF and MAP.

NEW FRONT O2 SENSOR TOGGLE – Allows front O2 sensor to be toggled on/off, both MAF and MAP.

NEW REAR O2 SENSOR TOGGLE – Allows rear O2 sensor to be toggled on/off, both MAF and MAP.

NEW IMMOBILIZER TOGGLE – Allows Immobilizer functionality to be toggled on/off, both MAF and MAP.

NEW BAROMETRIC PRESSURE SENSOR TOGGLE/TABLE – Allows barometric pressure sensor to be toggled on/off and locked to a specific value, both MAF and MAP.

NEW POST-START EMISSIONS REDUCTION TOGGLE – Allows turning/on/off specific fueling strategy post-start for catalyst light off, both MAF and MAP.

PASSTHROUGH DATALOGGING – Datalog directly to AccessTUNER software.

Acquiring AccessTUNER Race Software
Updated AccessTUNER Race software can be downloaded from the AccessTUNER Race Request Page. In an effort to get this software out to you as quickly as possible, three versions of the software are available for download:

  • 2006 CIVIC Si (Coupe)
  • 2007-2009 CIVIC Si (Coupes/Sedans)
  • 2006-2009 USDM CIVIC – MAP (MT)

You must download the software appropriate for your vehicle year and tuning logic. If you want the option to tune using MAF and MAP, you must download the appropriate MAF version of the software for your vehicle year and the MAP software, which will require two separate software requests. In the near future, these will be integrated into a single software package. We felt it was more important to make this software available to you rather than delay it to provide it in the optimal packaging.

Updating AccessTUNER Firmware
Plug the AccessPORT into your PC using the USB port and launch the AccessPORT Updater application. Follow the on-screen prompts be sure to check the beta firmware option. The firmware will then be downloaded an your AccessPORT will automatically be updated to the most recent version of the firmware. (version 1.5.0.3)

Happy Tuning!
