Over the years, Vi-PEC has changed in many ways

The principles that define Vi-PEC haven't - power, ease of tuning, performance.

When we set out to create Vi-PEC's new look, we wanted to make it more pleasing, easier to use, while maintaining the elements essential to Vi-PEC.

It's the next natural step in the evolution of ECUs. Not just because of how it looks. But because of what it empowers you to do.

The elegant design feels entirely fresh - the i88 will change how you see your car, and what you can do with it.

When you refine every detail, the entire experience is enhanced

Thoughtfully redesigning the i88 enclosure meant going deep into every aspect and focusing on details, large and small. There are obvious changes to big things, like shape, colour, mounting bracket but there are more subtle changes to a lot of small things, like the internal heat-sink which allows the ECU to run cooler for increased reliability, plus a status LED and branding.

The more you use your i88, the more you'll notice, the more you'll love.......

The Vi-PEC i88, our most advanced ECU. 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. See the setup screen

Features

Conversion of all code to suit a new more powerful micro controller

Support added for the new range of iSeries ECUs

iSeries ECUs are shipped as "Locked" and must be enabled before they are used. This increases security of shipping high value products and provides information on when an ECU is first used for warranty purposes

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 now record continuously, overwriting oldest data when the memory is full

A new log file down loader has been added that allows faster download of all or any part of the logged data

The number of General Purpose Table Allocation Slots has been increased to 30

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 currently implemented but will be improved in the future

The ECU and VTS iSeries now work 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)

The ECU now 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 now 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 now have their values assigned from CAN

Driven and non-driven wheel speeds have been added. These can be configured in various ways to drive off the four wheel speeds

All functions that use speed no longer require a digital input to be selected. They now use either driven or non- driven wheel speed as appropriate

Options added to GP Output switching conditions to suit new features (eg Slip, individual wheel speeds, Lambda)
