Outline

WOT fuel (actual) is primarily based off the WOT lambda adjustment. It is advised to set the lean best torque the same relative to the axis provided.
EGR Ignition – leave stock
Knock ignition limit – this is the table available that will adjust the ignition timing. It is not the actual ignition timing. It is just a limit that can be adjusted up or down. Higher octane-based fuel can have a higher limit. Lower octane fuel will require a lower limit. Note; all base maps were tested on 91 octane thus the limit should not have to be lower than as delivered.
Knock sensitivity cylinder 1-4, & 2-3  - adjusts knock sensor sensitivity.  Larger numbers are decreased sensitivity; larger numbers increase sensitivity.
TC maximum pressure ratio – this is the main boost target table. Y-axis is rpm and X-axis atmospheric pressure.  Numbers on the z axis are the pressure targets i.e. 2.650bar->2650mbar->265kpa->38.43psiA->23.73psiG
TC ma boost (IAT) & TC max boost (PA) - these tables are over-boost error thresholds based on there X-axis. If boost were to hit the values in table, an error condition will occur and you may loose your boost until the error is cleared.
Boost by gear limit – boost target ceiling based on gear and rpm.
Knock air limit – restricts the amount of cylinder filling.
Ethanol ignition compensation – ignition compensation used when flex fuel is enabled. X-axis is manifold pressure, Y-axis is rpm.

 

Closed Loop

Only toggle (use map to determine WOT) if deemed necessarily. 99% of users won’t need to do this.
WOT determination (mg/cyl) is basically saying how much airflow is required at a certain rpm to be deemed WOT

 

Rev Limits

Anti-lag is to be used with extreme caution

 

Sensors

AFM is the air flow meter calibration. This table is directly influenced by the AFM/MAF housing and airflow. i.e. this table can be used to fine tune the fuel trims to +/- 5% and to further dial in WOT afrs to match the target thus less closed loop trim needed at WOT.

 

Boost control

If one wants the sport button to raise boost when toggled, and lower boost when not toggled - which is ultimately controlled by the torque limiter; have both scramble (max boost) enabled and enable scramble via sport button toggled in this window.

 

Ethanol

Ethanol percentage – flex fuel sensor translation
Ethanol fuel compensation – fuel compensation based on ethanol content
Ethanol ignition multiplier – percentage of (ethanol ignition compensation) added based on ethanol content
Ethanol cranking compensation – additional cranking fuel added based on coolant temp
Ethanol WOT fuel compensation – adjusts lambda target based on ethanol content
Boost by ethanol limit – boost target ceiling based on ethanol content

 

Torque

Torque limit – torque limit when not in sport mode
Sport torque limit – torque limit when in sport mode
Sport button boost (Hondata mode) enabled – toggle this in conjunction with the other 2 boxes in the Boost Control tab in order to use both torque limit tables via the sport button
Torque limit explanation for both CVT and MT. MT doesn’t have economy button, it has a sport button.
The next factor that will limit the boost is the torque limiter found in window->calibration->torque
You have 2 torque limits, torque limit and economy torque limit (Sport torque limit – Si models). These limits are toggled with the econ (Sport – Si models) button inside the vehicle. You will not be able to log the actual torque the ECU is seeing, but you will know you’re hitting the limit by monitoring that your table boost target doesn’t match you bp-command or your t-pedal doesn’t match the t-plate or a combination of the 2. To get closer to your table target raise the torque limiter for the mode you wish. (CVT models) Raise with caution as to not over torque the CVT.

 

Note. The torque limiter functions by limiting power output via closing throttle, lowering bp-command, or altering the ignition timing or a combination of all the above.
