Q: How does the DieselPower Active Injection Control Module achieve it's gains?
A: The Active Injection Control Module achieves it's gains by adapting the fuel injection timing curve. The module is given the signal from the engine computer to open the injectors. This signal is changed to lengthen and change the time at which fuel is injected. This precise change in timing is what will give an additional 25% of Clean power. The results will amaze you!
A: The PD Modules we recommend settings B or C. Higher settings can be experimented with and adjusted to suit your individual driving style. When using the modules on the highest maximum settings it is recommended and beneficial to ease off on the throttle slightly at higher RPM'S to allow the engine to remain in the "Sweet Spot" of maximum torque.
A: The CR Module can be easily adjusted by starting off in the lower settings and turning the dial clockwise. The values start at 0-9 and the from A-F with F being maximum gain. When under full acceleration the engine fails to respond turn the dial back 2 notches counter-clockwise. During periods of high ambient temperatures it may be necessary to turn the dial back one or two settings.
A: The Digi Z Module for 1996-2003 VW TDI'S can be adjusted clockwise for more power until the engine fails to respond and the backed off 1 or 2 notches counter-clockwise for best drivability and performance.
A: The Digi VP Module can also be adjusted up to the point where the engine fails to respond, at this point decrease the setting 2 levels back.
A: Consumers of aftermarket products are protected by the Federal Magnusson-Moss Warranty Act. The act states that if something breaks on your car and you take it in for warranty repair, the dealer must honor your warranty unless they can prove that whatever modifications you have added to your vehicle actually caused the problem. Legally, a vehicle manufacturer cannot void the warranty on a vehicle due to an aftermarket part unless they can prove that the aftermarket part caused or contributed to the failure in the vehicle (per the Magnuson Moss Warranty Act (15 U.S.C. 2302(C)).
A: NO; however hard driving styles or abuse can cause damage to transmissions even at stock power levels, and the increase in HP and Torque could accelerate this.
A: YES, based on your driving style and the type of fuel injection system on your vehicle it is possible you will see a 10% improvement in fuel efficiency due to the significant increase in low RPM torque. Fuel efficiency will vary due to individual driving styles.
A: NO, we have monitored all vehicle with the modules installed and have recorded no significant increases in EGT’S.
A: The VW TDI airflow meters tend to go bad over time and give a rough signal at the #5 terminal on the MAF. The easiest installation of the AGR Z4 is to take the signal from this #5 wire. If the MAF is bad the AGR Z4 will tend to magnify the jerky performance. In this case we recommend taking the signal from the throttle pedal potentiometer. This wire is white/blue tracer and is located at the throttle pedal. This white/blue wire has .30 volts key on engine off and will increase up to 4.6 volts in smooth increments as accelerator is depressed.
A: NO, this is not normal.VW TDI'S have been plaqued with deposits of oil and soot building up in the Exhaust Gas Recirculation system and the intake manifold. This build-up will severely restrict the free flow of air that is required for the engine to run at peak efficiency. The result of this will be excess smoke, poor fuel economy and low power output. The EGR and intake manifold should be inspected and cleaned on a regular basis.
