The Vi-PEC i88 has flexible options over the control of inputs and outputs, allowing the user to design their own functions to control all sorts of devices. Precise control of injectors and ignition angle are guaranteed at very low or high RPM or manifold pressures. A very high level of protection from interference and tolerance of trigger input errors has been built into this ECU, ensuring a smooth running engine even under the most demanding conditions.
- Variable camshaft control for up to four camshafts. Control of camshaft position is very precise and time taken to advance from full retard to full advance is less than 1 second. Support for VVT and VANOS systems
- Closed loop control of idle speed and boost pressure makes for a "factory" idle speed stability, and precise control of boost pressure. Boost control can be setup to provide a different boost in each gear
- Individual Cylinder Knock control, with support for two sensors. Knock control is user definable with flexible settings to allow precise knock control adjustable by ignition angle
- E-Throttle (Electronic Throttle Control)
- Peak and hold injector drivers are 10 amp. Both the peak Amps and hold Amps can be set separately in the software for optimum injector control.
Features
i88 Features
- Trigger scope functionality
- Internal Digitally Signal Processed (DSP) Knock Control
- On board data logging has user selectable parameters and logging rates
- On board logging can record continuously, overwriting oldest data when the memory is full
- A log file downloader has been added that allows faster download of all or any part of the logged data
- 30 General Purpose Table Allocation Slots
- Configurable temperature input pullup resistors (Temp 1 and 2) - this allows the use of higher value pullup resister as required for some sensors. The pullup resisters can be turned off completely for piggy back applications
- ISO 15764 OBD. Can be used to connect to scan tools or mobile devices for display of ECU parameters. Skeleton functionality is implemented
- Works natively in Lambda instead of Air to Fuel Ratio. The Stoichiometric ratio of the fuel currently used can be entered into the Stoich Ratio setting. This allows display of all Lambda values in AFR for tuning if required (refer to metric/imperial units help)
- Uses metric units for all internal settings and calibrations. These can be easily converted to imperial units for display as required
- More flexible configuration of CAN modules. Standard and extended CAN identifiers are supported as well as more data rates
- Fully configurable custom transmit and receive CAN streams
- OEM CAN modes are available on both CAN modules
- Text strings can be stored to label inputs and outputs. Eg label a GP Input as "NOS Switch"
- A memo text can be stored in the ECU with tuner specific information
- Four wheel speed parameters have been added. These can be driven from a digital input or CAN
- Various parameters including wheel speeds, EGTs, AC Evaporator Temperature and AC request can have their values assigned from CAN
- Driven and non-driven wheel speeds can be configured in various ways to drive off the four wheel speeds
- All functions that use speed don't require a digital input to be selected. They use either driven or non-driven wheel speed as appropriate
- Starter Control function allows controlled activation of a starter motor solenoid. Allows a single push button to start and stop the engine or security systems to safely remote start the engine
- AC Control function has simple and full modes. Simple mode uses only an AC Request signal to operate the compressor clutch. Full mode takes into account high side pressure and evaporator temperature
- GP Outputs are evaluated every 20ms and have a resolution of 20ms on the switch off timers
- PCL files can be locked to an ECU. This allows the tuner to configure a file, lock it, send it to you and it can only be installed in your ECU
- Support for KMS CAN products
- A dedicated parameter for Oil Pressure Switch
- CDI CAN mode displays information from a Vi-PEC CDI. Eg Spark Energy, fault codes
- Communications speed up to 625 kBaud. Gives much higher PCLink data rates and log downloading
- The return to idle hold timer can be adjusted to control damping as RPM falls
- Stepper direction for Idle Control, CL Stepper and Rotary Oil Pump. Allows reversing of stepper direction without altering wiring
- OEM CAN mode for Polaris RZR 900
- An adjustable timer to prevent the engine fan running forever when the engine is stalled
- Volt based gear detection. This allows gear selection from a potentiometer sensor or switched resistor network
- Status for indicating if the vehicle is in a driven gear. Can be used in conditional outputs (eg for engaging AWD solenoid)
