- If you want to increase or reduce the power performance, you will only need to place the jumper to the left (increased efficiency) or to the right (reduced power performance). Please contact the manufacturer, before changing the jumper settings.
- Now fit the engine cover back on. The vehicle is ready for a test drive.

ill.6 installation principle

PDI Instruction
Information
The Performance tuning can obtain a different result throughout the series. It's possible that the engine power turns out to be too high or too low.
If the power should be too high, it is shown by a strong soot generation, disturbed engine run, engine misfire or the initiation of the engine emergency program.
In the emergency program the vehicle drives with a strongly decreased performance. In some vehicle models the engine control lamp shines. The emergency program is a protective function of the engine and can be deactivated at any time.
With fine-tuning these problems can be resolved. A fine tuning is normally not necessary, since the PDI module was balanced and programmed for the respective vehicle. Before a change is made, you should contact your salesman or the manufacturer of the system. A technician will gladly help you.
PDI Box's backside
On the back of the unit you can see two LED's and some jumpers. The left set of jumpers is used for the program selection. The right set of jumpers is used for fine-tuning the PDI Tuning box (see ill.1).
Fine-tune jumper (right)
Only one jumper must be present in this row. Jumper on T position gives settings as made in configuration program. Now you can raise or lower the power output by setting the jumper on a positive or negative value. (see ill.2, ill.3 and ill.4). Jumpers which are put in horizontal position have no influence.
Program jumper function (left)
0, 1 or 2 jumpers can be applied in this row (see ill.5) Should a not configured program be selected, program 1 is automatically called.
| Jumper 1 | Jumper 2 | Program |
|---|---|---|
| Off | Off | 1 |
| On | Off | 2 |
| Off | On | 3 |
| On | On | 4 |
LED's
- Red LED: Device ready for use.
- Yellow LED: Tuning is active.
- Both LED's shine only while driving.
- With the contact on, fine tuning selection is not possible.
