Outputs

Customizable outputs

There are several configurable outputs in the ECU. Their number and capabilities depend on the hardware version of the unit.

After connecting to the ECU, the "Outputs" tab shows the current settings for a specific version of the ECU.

Outputs can be named (up to 8 characters). Names are permanently stored in the ECU and are not erased after updating the firmware. To enter a name, click on the tab.

Inversion

Inverts the output state. If the output was active, it becomes inactive, and vice versa.

Started engine

The output is activated only on the running engine. On a stopped engine, the output is always off, regardless of the specified rules.

Off at full load

Disable output if the accelerator pedal is fully depressed

Additional condition

  • AND - active if both conditions are met at the same time
  • OR - active if any or both conditions are met.
  • XOR - active if only one of the conditions is met, but not two at the same time
  • Idle correction - changing the position of the Idle valve when the output is turned on and off. Adjust the value to eliminate fluctuations in the idle speed when load is turned on or off.

Delay on/off

You can set delays for enabling and disabling outputs.

  • on - after the condition is triggered, the output is delayed for a specified time
  • off - after disabling the condition, the output is kept active for a specified time

Description of output functions

Most functions work according to simple rules: you set the thresholds for enabling and disabling. The output is activated according to the specified conditions.

There are two options for setting values:

  1. On > Off For example: On = 95 degrees, Off = 90 degrees. The output will turn on if the temperature is >95 degrees, and will turn off when the temperature is <=90.

  2. On < Off For example, On = 3000, Off = 4000. The output will turn on if 3000 < RPM < = 4000. Some functions work according to special rules. These are described below.

Petrol pump

Off Delay - sets the operating time of the gas pump after stopping the engine or when the ignition is turned on. If the On delay is not zero, the fuel pump will not turn on after turning on the ignition.

Methanol

The output is activated according to the specified MAP values. Corrections are applied with the activation of the output

Detonation

Output is activated when the knock ignition retard is active

Injector rails 1/2

Modes are designed to control two rows of injectors. The outputs are controlling power supply to the injector rails.

The mode of rails switching is selected on the Injection - Rails tab

Air conditioning

The mode is designed to control the clutch of the air conditioner compressor. When the air conditioner is turned on, the fan outputs are turned on and the ICV correction is triggered.

To reduce the shock load, set different delays for turning on the air conditioner and fans

The control algorithm is activated using the switch input and the AC pressure sensor input.

  • If both inputs (button and sensor) are provisioned - the air conditioner will turn on if the button is pressed and the pressure is within the specified limits.
  • If only the switch input is provisioned - the air conditioner will turn on if the switch is activated.
  • If only the AC pressure sensor input is provisioned, the air conditioner will turn on if the pressure is within the specified limits.

If you can't dedicate both pressure input and switch input - it's better to use the pressure input. Connect the button which turns on the air conditioner so that it supplies power to the pressure sensor. Then, when the button is turned off, the zero voltage at the output of the pressure sensor will turn off the air conditioner.

The voltage limits of the sensor are specified in the parameters of the adjustable output. There are two configuration options:

  1. On < Off. For example, On = 2v, Off = 4v. If the voltage is in the range from 2 to 4 volts - the air conditioner will be on.
  2. On > Off. For example, On = 3v, Off = 2v. If the voltage exceeds 3V - the air conditioner will turn on, and will work until the voltage drops below 2V.

Fan

On/off thresholds are adjusted according to the engine temperature. The fans are forced ON when the air conditioner is working.

Starter lock

Designed to control the relay that disables the starter circuit. ECU will block the starter on the running engine, and also automatically turns off the starter when the engine starts.

Check Engine

Designed to connect a Check Engine lamp

Constant on - error detected, or the engine stopped

Blinking - autostart works

Autostart

Connects to the starter relay. Designed for starting engine with the button.

In the input settings, select the channel to connect the start button. The algorithm is activated by a short press of a button.

There are 3 attempts, after which the algorithm will turn off.

The Check Engine lamp signals the operation of the starting algorithm.

Gas valve

It is used to turn on the gas valve when working with LPG. The gas valve is activated when switching to gas fuel.

Indicator Gas/Petrol

Indication of the operation of the gas/petrol system.

  • ON - works on gas.
  • OFF - works on petrol.
  • Slow blinking - waiting for the transition to gas.
  • Quick blinking - run out of gas, works on petrol.

Traction

Indication of traction control operation

Button

Uses button state. The On parameter specifies the button number.

Shift light

Turns on the output if the revs are close to the RPM limit. The parameter specifies the revs delta. For example, if the limit is at 6000, and the parameter is 200, then the lamp will turn on at 5800.

PWM parameters

There are two types of PWM channels:

  1. Single. PWM frequency is set separately.
  2. Dual. The PWM frequency is set for two outputs simultaneously. They have a lower maximum frequency, and fewer features are available.

Frequency, Hz

Sets the frequency of PWM operation

Inversion

Inverts PWM output

PWM Modes

Idle valve

To connect inductive Idle valve. Frequency 75-100 Hz To connect a dual-winding valve, set the Idle mode for dual PWM channels, and turn on the inversion for one of them.

Wastegate

To connect the Wastegate solenoid. Frequency 20-40 Hz.

VVT1 / VVT2

To connect the VVT solenoids. Frequency 300 Hz.

Absorber

For connection of the absorber purge valve.

Tachometer

Allows you to generate a tachometer signal with customized frequency, from 0 to 200% of the TACH output frequency. Available only on single PWM channels. Configurable in the tab below.

Speed

Generates pulses of the speed sensor with customized frequency. Available only on single PWM channels. Configurable in the tab below.

Manual

You can manually set the PWM duty cycle. Configurable in the tab below.

Table 3D

You can set the PWM duty cycle depending on RPM and load

P1,P2,P3,P4

Programmable duty cycle rules. Configurable in the tabs below.

P1*P2

Multiply the results of program 1 and program 2. Result = P1duty * P2duty / 100

Max(P1,P2)

the maximum value from both programs is selected Result = Max(P1duty, P2duty)

Program tabs P1,P2,P3,P4

Here you can program PWM duty rules:

  • the parameter by which the duty will be calculated
  • parameter limits
  • % PWM duty cycle at limit values

Off flag

If the checkbox is selected, then if you exceed the limit value, the duty cycle will be set to 0%. Otherwise, the limit duty cycle will be retained.
