To get the most from your PowerCard, it is important to recognize the difference between “load,” and throttle position/RPM. For example, put your motorcycle in first gear and hold the throttle wide-open, then do the same thing in fifth. Notice how the rate of RPM change is much faster in first gear than in fifth. This is because the load in fifth gear is much higher. Any given combination of throttle position and RPM can be associated with vastly different loads. PowerCard recognizes this, and uses proprietary algorithms to apply the right amount of additional fuel in the right circumstance. The PowerCard technology is unique because it is load based and does not rely solely on throttle position and RPM; it determines load based on the output from the factory programmed ECU, which has had thousands of hours of development and uses many sensors. Once the PowerCard “knows the load”, you can adjust it to provide the extra fuel needed to get maximum performance from your modifications.

The Multi-Tester plus/pro software cassette is the component that gives the diagnostic equipment its unique test characteristics: All data required to make the test system operate are stored on the software cassette. The software cassette can be easily replaced enabling the Multi-Tester plus/pro to be rapidly adapted to the trouble-shooting job at hand. These Trouble-Shooting Instructions describe how to use the equipment on Magneti Marelli - Weber fuel injection systems type IAW. Multi-Tester plus/pro checks all input and output signals that have bearing on the control system and can also diagnose a faulty control unit.

This is a guide to cleaning the Mass Air Flow (MAF) sensor, infamously known to VW owners as a problem part. This problem seems to have become more widespread with the release of the Mk. IV platform, which is apparently due to a bad batch of sensors from the Bosch factory. Although most of the faulty MAFs have been weeded out after having failed on their owners, the more hardy MAFs often survive until just after the car’s warranty expires. In most cases the owner is left holding a bill for several hundred dollars for a new MAF and labor costs.
