Additional miscellaneous parameters.
ECU Options
Immobilizer enabled - Sets whether the immobilizer is enabled or disabled. Keep the immobilizer enabled except for engine-swaps where the vehicle has no immobilizer key and transponder.
Note that if you enable the immobilizer you must switch the ignition off and on before the engine will start.
OBDII - Enables/disables most OBDII functions. To remove the secondary o2 sensor error (from using a race header with no catalytic converter or secondary o2 sensor) clear the check mark from the OBDII box. Note: Only disable OBDII for race vehicles, as doing so will prevent many OBDII functions and sensor error testing from being performed.
Purge system - should only be disabled for race vehicles with no evaporative controls, otherwise the purge canister will fill with fuel.t
ELD - disable for vehicles without an ELD circuit (eg engine swaps).
Ignition Timing
Cold retard - enables/disabled ignition retard when the engine is cold. Some vehicles run significantly better when cold if the ignition retard is disabled.
Copy Protection
Copy Protect ECU Calibration - checking this will prevent the calibration from being downloaded from the ECU. Warning: If you check this, be sure to save the calibration to disk, as there is no way of reading the calibration from the ECU once copy protected. This feature is currently disabled.
Air Conditioning Switch Input
Normally the AC on signal is sent to the ECU via the multiplex communication bus. For vehicles which do not have the multiplexer, it is possible to use the VTP input as an alternate AC switch input. Note that the multiplexer and VTEC pressure check should both be disabled. The normal ECU AC clutch output is used.
ECU Speed Correction
Countershaft driven speed sensor - check this option if using a transmission with a countershaft driven speed sensor (e.g. 2005 RSX). The ECU will then convert the pulses from the speed sensor to the correct frequency for the gauge cluster. Note that enabling this option will automatically disable OBDII functions.
No speed sensor - check this option is you do not have a speed sensor input. The vehicle speed will be set to a constant 80 kph / 50 mph. Note that using this option is only recommended if there are no other alternative, as the speed signal is important for the correct operation of the ECU. You will not be able to use the reverse lock out. If at all possible, use a speed sensor input.
Speedometer correction - adjusts the speedometer output in percentage steps, positive or negative. Works for normal speed sensors and countershaft driven speed sensors.
