Tuning Notes

Also see Turbocharger_Notes
Knock control for the 2.0L can vary between 54 to 80 percent.  It is common to have a knock control around 75 percent.
To set up different power levels, enable Hondata mode and set the Economy torque table lower than the normal table then you can switch between them using the ECON switch.
When rev hang has been disabled, turning the main cruise control button on will cause the throttle to go back to stock behavior.

 

Dyno Procedure

 

Gear ratios

3rd gear – 7.75675
4th gear – 5.66935
5th gear – 4.6292

 

Disable VSA

1.Switch on ignition but do not start engine.  Release the parking brake.  Press the brake pedal.
2.Hold VSA control until VSA disable light is on.  Hold again until light goes off.
3.Switch on the parking brake on and release the brake pedal.
4.Hold VSA control until VSA disable light is on.  Hold again until light goes off.
5.Press and hold the brake pedal
6.Hold VSA control until VSA disable light is on.  Hold again and the VSA disable light should flash.

Note that this must be done each time the ignition is switched off and on.

 

Dyno

Start engine (without switching off ignition).
Release parking brake
Put car in 2nd gear and cruise under minimal to no load.  VSA as well as other systems will fail which will then allow the car to shift.
Shift to desired gear for dyno.
For dyno pull  launch in F3 mode, suggested window is 2500 rpm to 6200 rpm, no lead-in or lead-out, sweet rate 500 rpm/s
Throttle pedal initially needs to be 35-40% so that the transmission will not downshift.  Note that the throttle plate will open fully with this pedal input.
At 3500 rpm start increasing throttle to 100% at 4500 rpm.

 

VSA and other errors should clear after a short drive where all four wheels are turning equally.

 

Dash Errors

If after reflashing the dash shows multiple errors (ABS, ACC etc).

Ignition on engine off
Clear errors code using OBDII diagnostics Note that the last tab 'diagnostics' should be used. Refresh DTCs and then clear DTCs.
Switch off ignition, restart vehicle
Drive the vehicle for 5 minutes
Ignition on engine off
Clear errors again using OBDII diagnostics in the same way as above.
Switch off ignition, restart vehicle
