We know that there are no two cars that are 100% identical. We decided to bring you a tuning tool to complement our software. The PiggyBack units we use are powerful, reliable, flexible, user friendly and cost effective.

The PiggyBack offers you many features

• ADDS TUNING CAPABILITY TO YOUR ENGINE
• TUNE ONLINE VIA YOUR PC, NO RE-CHIPING NEEDED
• TUNE WHILE YOU DRIVE
• MONITOR & TUNE AFR (Lambda)
• LOG YOUR ENGINE PERFORMANCE
• TUNE YOUR ENGINE THE SMART WAY
• SAVE SETTINGS
• TWO SEPARATE SETTINGS STORED IN MEMORY

WHY A PIGGYBACK?
The PiggyBack was designed to allow you to tune ANY engine. Signals are modified on maps found within the units and with windows software. Installation and tuning is simple and once installed the engine can be retuned by anyone with a laptop and the tuning software. An average installation consists of connecting 6 wires to the vehicles original wiring loom, changing the settings of the unit in the setup section of the tuning software and you are ready to retune the car. It has been found that an experienced installer can install an PiggyBack unit within 30 minutes.

FEATURES & BENEFITS OF THE PIGGYBACK
All piggyback units are reliant on the exiting ECU to provide the fuel and ignition to the engine. For this reason they are bound by the limitations of the existing ECU. Fuel is typically modified by changing the load sensor or lambda sensor signal. Ignition is done by delaying or advancing the crank angle sensors signal. The piggyback unit tricks the ECU into thinking that it is running under different conditions thereby allowing for a different output.

The PiggyBack, has the ability to drive an extra injector which will allow more fuel to be added into the engine typically for turbo applications.

Wiring diagrams
A wiring diagram will be supplied with each unit.


Software & Manuals
All software and manuals are provided with each unit. The PiggyBack software is Vitesse exclusive.

Tuning
Tuning with the PiggyBack is very simple. The Windows based interface is intuitive. The PiggyBack allows you to perform Data Logging. The Log file can be E-mailed to Vitesse for assistance. We have tuned many cars from a remote location. You can playback your log file, which makes tuning that much easier. Ignition tuning is not recommended nor supported. During for the first 30 days after purchase, you get one half hour of free tuning support via e-mail.


New Applications
We are constantly working on new applications.

The following applications are controlled by the PB based on LOAD/RPM/BOOST:

• Water Injection
• Boost Control
• Ignition Tuning
