After buying all those aftermarket products, aren’t you curious if any of them really improved your vehicle’s performance? Maybe you’re simply curious about what your vehicle is capable of?
Measuring performance is as important as selecting the products that grace your vehicle. The two go hand-in-hand. With SpeedTracer, we’ll help you get answers to those questions. AutoEnginuity’s SpeedTracer performs vehicle performance analyses by communicating directly with your vehicle through the OBD-II connector. It will retrieve RPM, MPH, ambient temperature, and barometric pressure.

Sometimes referred to as a 2-step or launch controller, the LNC-002 adjustable RPM limiter and timing retard controller can be used to provide consistent launch RPM off the line in drag racing and other standing start racing applications. In turbocharged applications the LNC-002 can also be used to retard the timing in order to build more boost at the line.

Finally the procedure we have all been waiting for: the “A4 Timing Belt Procedure“, including the automatic and manual transmission differences. Some people have argued till they are blue in the face that “mark and pray” was the easiest way to change one of these belt, and it has been proven that this belt can be changed in under 2 hours using the full factory method as demonstrated here in this thread. The procedure utilizes all the factory tools and processes. The reason for going to the extreme of utilizing all the tools is the elimination of all possibilities of making a $2500.00+ mistake and destroying the head. You do not need many tools to complete this job. What you do need is a thorough understanding of the procedure and what you are about to accomplish.

The Rotary-engine Compression Tester can be used to obtain accurate engine compression measurements in a rotary (i.e., Wankel) engine. The Tester combines the output from an AST pressure transducer with the data conversion function of a DATAQ analog-to-digital device to acquire and record accurate compression readings for each face of each rotor in a rotary engine. This system also allows the calculation of engine cranking RPM during the test for data normalization.

Some vehicles may experience difficulty starting (cranks no start). This may occur after driving the vehicle a short distance without engine reaching normal operating temperature. Examples: starting a vehicle and moving it to wash it, engine stall due to mis-application of clutch then restart. This commonly occurs at port facilities or dealer lots where vehicles are frequently started cold, moved for short distances and then turned off. This concern may also occur due to low cranking RPM during engine starting.

The compact all wheel drive (AWD) market has enjoyed particularly healthy sales in recent times with a number of new and very good offerings competing for a share of sales. One of the latest releases is an all-new wagon called the Outlander, that Mitsubishi intends to market as an ‘adventure picnicker’. While it is set to replace the iO, which is currently in run-out mode, the Outlander is a larger vehicle that provides significantly more interior space.

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.

You’ve lost fire in your engine. No matter how hard you pull nor how much you crank the starter motor, you can’t get a pop. With the price of parts being what it is, just replacing components to troubleshoot your system is not only foolish it can be down right expensive. It never ceases to amaze me how often operators will miss-diagnose an engine problem and then spend major money to replace perfectly good parts. This month we’ll show you some simple checks you can do to test each of the components in your Ducati ignition.

There are two powerful, five-cylinder engines available for the XC70, a petrol and a diesel. Both are turbocharged and offer the flexibility of high levels of torque at lower engine speeds.
The 2.5T petrol engine boasts four valves per cylinder with a light pressure turbo and dual continuously variable valve timing to provide stirring performance with excellent mid-range torque.
Volvo’s new D5 Euro IV turbodiesel is a refined, all aluminium unit, with 20 valves, and the latest common rail technology. It is available with a six-speed manual or a new six-speed Geartronic transmission.
