COBB Tuning is pleased to announce significant updates to the 8th generation Honda Civic Si AccessPORT maps and AccessTUNER software. Tuning improvements such as additional intake cam advance, individual cylinder fuel control, individual cylinder ignition control, injector scaling, adjustable breakpoints, ECU learning limits and additional ECU logic toggles give the tuner significantly more control. So significant that a simple alteration of the MAF housing opens the door to the big power gains of forced induction tuning. Furthermore, MAP based naturally aspirated and forced induction tuning is just around the corner!

The calibration specialists at COBB Tuning have already employed the tuning software upgrades to uprev the free Off-The-Shelf maps to version 1.03. Users can expect performance improvements from the removal of the upper limit of variable camshaft phasing, improved variable timing control transitions at higher loads and revised variable timing control settings when in High VTEC. Simply connect the AccessPORT to your PC and open AccessPORT Updater to download the latest firmware and new v1.03 maps and experience these improvements today!

The latest version of AccessTUNER Race tuning software is now available for download. The improvements in the new software give much more granular control of the combustion process on a per cylinder basis, give the user control of camshaft advance breakpoints and introduce forced induction tuning on the Honda Civic Si using the AccessPORT. Detailed explanations of these enhancements are as follows:

USER ADJUSTABLE CAMSHAFT ADVANCE BREAKPOINTS – Camshaft angle based ignition related tables (Ignition Advance and Knock Sensitivity) now have user configurable breakpoints.

PRIMARY O2 SENSOR CALIBRATION – This table allows the front O2 sensor calibration to be rescaled or “corrected” so that it reads accurately.

MAX ALLOWED VTC - This table represents the maximum amount of intake camshaft advance that the ECM will allow to be targeted. These settings are effectively ceilings that dictate the maximum amount of intake camshaft advance that can be run, up to the mechanical limitations of the camshaft.

MAX ALLOWED VTC MIL DETECTION LIMIT - This table tells the ECU the camshaft phasing point at which it should recognize MIL P1009 (Variable Valve Timing Control (VTC) Advance Malfunction). If the variable camshaft phasing values go above this limit then the ECU will detect something is wrong with the camshaft phasing controls and will detect MIL P1009.

FUEL CYLINDER 1, 2, 3 & 4 COMP - These are compensatory tables used to modify fuel delivery to each cylinder individually.

IGN CYLINDER 1, 2, 3 & 4 COMP - These are compensatory tables used to modify ignition calculations for each cylinder individually.

MAX ALLOWED IGNITION ADVANCE - This table represents the maximum amount of ignition advance that the ECU can run and is effectively a user configurable ignition advance ceiling.

MINIMUM ALLOWED IGNITION ADV A, B, C & D - This table represents the minimum amount of ignition advance that the ECU can run is effectively a user configurable ignition advance floor.

BASE PULSE WIDTH - This table defines pulse width for fuel injection calculations based on RPM and is used as an injector scalar for controlling different size fuel injectors or for running significantly different fuels, like E85.

LTFT LIMITS – This table controls the limits for LTFT learning. The negative value is the greatest negative LTFT value that can be learned and the positive value is the greatest positive LTFT value that can be learned.

CLOSED LOOP TOGGLE - This toggle is the main function switch for turning the closed-loop feedback system logic ON or OFF.

POWER STEERING CONTROL SYSTEM - This toggle is the main function switch for turning the PSCS system ON or OFF.

VEHICLE DYNAMIC CONTROL - This toggle is the main function switch for turning the VSA feedback system ON or OFF.

 

so i'm curious... is there an O2 simulator in either of these so i can run a catless header with out having a CEL... or MIL... i dunno what people call them on this forum... after owning VW's pretty much all my life i'm tired of seeing the christmas tree of lights that is the gauge cluster on an OBD2 VW...

 

So I'm curious. When I buy my engine managment to run E85 would AccessPOrt or FlasPro be better. Which has more control?

 

You don't need a defouler with the AP installed on your car. There is a checkbox that you check to get rid of the MIL.

 

Hondata has a lead right now because, they've been tuning honda's for quite some time. The AP is gaining ground currently. I'm still on the fence about the wonders of E85. It's nice to tune with but, overall sucks for daily driving.
