HPI | Horse Power Ignition
CDI options:
 Exhaust valve / Tacho exit
• UNIVERSAL: The CDI will have an additional red wire that can be connected to work on most REV-counters (tacho).

• TWO-STROKE POWER VALVE SYSTEM: This system is used on some bikes as an improvement to a conventional two-stroke engine to give high power output over a wider RPM range. We have developed our CDI's to work with some of these systems: Yamaha's YPVS and Suzuki's AETC.
 Tacho exit
 2 Curves
The CDI will have two additional wires that allow you to switch between two different ignition curves. Selecting the curve can be done by simply connecting or diconnecting these two wires, or by selecting the curve with a switch (image on the right).

Order code for the switch: 068V064
 2 Curves
 Programmable
Only for digital units. Draw your own ignition curve with our TuneBox software, and program it into the CDI with the interface. The TuneBox software is free, and the latest version can be downloaded from the link below.

 Powerjet
PowerJet is only available on digital CDI-units and can be set up with the TuneBox software. It is an exit which is able to draw 2 amperes to ground in 2 user defined RPM regions. This can be used to drive a valve or light at a desired RPM range.

This is an optional exit for most vehicles. If, however, the vehicle already uses this system, our CDIs will be equipped with this system as standard. This means no additional wires, as the system is implemented into the wiring loom or connector, as with the original CDI.

If the vehicle has no standard PowerJet installed, this exit comes as an extra wire. Users should build a valve system on their engines themselves.

 Shift System
Shift Delay System (SD) is only available on digital CDI-units and allows to shift gears without clutch. The shift delay system will retard or interrupt the ignition momentarily to release the transmission load. In this moment the rider can shift up without throttling down.

The shift delay system comes as an additional 2 wire plug (with counterpart) and can be fully adjusted to be used with any input switch, which has to be installed by the user. Use TuneBox to set the SD for normal open or normal closed switches. Set the SD to retard the ignition 60° or to interrupt the ignition for a programmable period of time.
 Shift System **
 Throttle position
Throttle Position Sensor (TPS) is only available on digital CDI-units. It is an optional input which will determine which advance curve will be selected. With TuneBox you will be able to draw 6 different advance curves. The TPS will then decide which one is activated.

Use the TPS in combination with the curve switch:
• Position 1; The CDI will ignore the TPS. The CDI will then select curve 1, which can be used for sound tests.
• Position 2; The TPS signal will determine which curve is selected. Low throttle selects curve 2, full throttle selects curve 6.

If the vehicle has no standard TPS installed, this input comes as an additional 3 wire plug. Users should build a TPS on their system themselves.
