Mainline Dyno FAQ's

Q.    How long has Mainline been in the business?

Mainline Automotive Equipment Pty Ltd has been continuously trading, uninterrupted, since 1992. We have always been a privately owned, and operated, Australian company. In 2002 Mainline formed a technical and strategic partnership with DynoLog Dynamometer Pty Ltd., which had been trading since 1995. Both companies produce what is now known as the advanced Mainline DynoLog Dynamometer or “Mainline Dyno for short!

Q.    Why did Mainline form an alliance with DynoLog?

A.    A technical partnership, or joint venture, is quite a common business practice which has distinct advantages and benefits to both parties, than just an individual company trying to go it alone.  

Combining all our technical and other resources has been mutually beneficial to both companies. It has extensively expanded our service and customer support network, allowed active product development to occur unaffected by production, sales and/or marketing pressures, and has ultimately resulted in achieving a much larger market share, within Australia and throughout the world.

Over the last 10 years, our strong alliance has been very successful. We produce a high quality product, incorporating the most advanced dynamometer control and data acquisition system available today. Our association with DynoLog has also allowed us to maintain the highest standard of engineering excellence, innovative software features, and the highest possible level of Australian sourced production materials and components, without seeking cheaper offshore alternatives.  

Q.    What dyno components does Mainline import?

A.    As there are no retarder manufactures in Australia, we import Frenelsa eddy current retarders direct from Frenelsa in Spain. The retarders are made to our specifications to suit our particular requirements, and dynamometer applications.  Frenelsa retarders are considered the best in the business, and have they have proven to be very efficient, and reliable, in our dynamometer applications.

The vast majority of our raw materials and components are sourced, not only from within Australia, but from business’s in our local community as well, supporting local jobs and industries.

Q.     Where are Mainline DynoLog Dyno’s made? 

A.    Mainline Dyno’s are manufactured and assembled in Australia at our Sydney facility. The dyno controller units are manufactured at our Melbourne facility. Our software development team is also located in Melbourne. The final unit assembly, calibration and testing of completed dynamometer assemblies is carried out at our Sydney factory. Completed units are packed and shipped from our Sydney premises. 

Q.   What makes a Mainline DynoLog Dyno so good?  

A.   The two main reasons our system is superior to other units, can be attributed to our dynamometer control system, and the vast data logging capabilities, along with the type, quality, and diagnostic value  of data that can be acquired with our system.  We also provide depth data analysis software tools that make tuning or diagnosing a vehicle must more efficient and profitable.  The term “Control System”, refers to the hardware behind the user interface that controls the dynamometer and the vehicle speed, or engine speed, during a “Ramp” or Steady State” type condition.   

Q.   Why is a good control system critical?

A good dynamometer control system ensures that when performing a “Ramp” type test, the acceleration rate of the vehicle (and the vehicles engine speed) is always a linear progression at the precise acceleration rate selected, which ensures repeatable results, and maintains consistent  thermodynamic properties of the engine under test.

The control system must be able to respond instantly to sudden changes in torque and power influences, such as an aggressive turbo or nitrous injection without fluctuation. A poor control system will not respond fast enough and will induce data fluctuations while trying to re-establish and maintain control.

Poor control systems will generally produce graphs with erratic trace curves, instantaneous power spikes or other indications that the dyno control system is not controlling effectively.  This characteristic is more evident at higher power levels. (800+ Hp).

Research graph images on the internet from different dyno manufacturers and you will certainly find many examples of this occurrence. Compare these graph examples to any Mainline Dyno graphs and you should start to appreciate the distinct differences in control systems.

A reliable engine RPM source, logged and graphed, will easily substantiate whether a dyno maintained a linear acceleration rate during the test, as the engine RPM graph trace should also progress in a linear manner. Many lesser dynamometers either do not offer any direct engine RPM source inputs, or only limited low voltage crank source only. We encourage all our users to log engine RPM on every test, as apart from confirming the integrity of the dyno control system, engine RPM data information can be a very valuable diagnostic tool.

Q.   What makes a Mainline Dyno Dyno different to its competitors?

A.    The underlying, and distinct, difference a Mainline Dyno has over its competitors units is primarily the control and data acquisition system, and the vast amount of available hardware options and software tools, and how these devices interact within the dyno software program to dramatically enhance tuning accuracy and efficiency.    

One such tuning tool that increases tuning efficiency is our “Target Fuel” function, whereby the user defines a Target Air: Fuel ratio or Lambda value, then after performing just one Ramp test, the dyno software shows the tuner what the difference is between the measured Air: Fuel Ratio  and the required Air: Fuel Ratio. This can be either a visual trace on the Air: Fuel Ratio graph or a more detailed data table format, which is configurable to any tuning software program parameters.

The values from the Target Fuel table can be quickly applied to the appropriate table in the ECU tuning software being used. The dyno software even provides an on screen ECU fuel change calculator, that allows the tuner to enter the vehicle’s fuel table value, and the dyno software will calculate and display what this value needs to be changed to achieve the desired target Air: Fuel Ratio.

The vast majority of performance tuning carried out these days is via Re-Flashing the ECU. The time that can be saved using our target AFR function can be literally hours, making the tuning job much more profitable, as multiple runs are not required to reach the desired fuel mixtures. Always thinking outside the square, in the case of Target AFR, we don’t just provide percentage correction values, but we also supply the values in a “Ratio” format which many tuning software programs require for changing table values.

Most of our advanced features and functions, and not offered by our competitors at all.

Q.    Why do many previous users of other brands purchase a Mainline Dyno?

A.     A first time buyer will tend to only consider the initial price of a dynamometer, and just assume they all do the same job. They are not looking further into the future and consider how a dynamometer can be a key part to their business income generation. What they are lacking is having experience of either a good or a bad dynamometer system to know what the differences are, and what they require to keep pace with future vehicle technology.

A large number of our sales are to experienced dyno users are fully aware of the strengths and weaknesses of their previous dyno system, and are looking for a better system or seeking better support than what they experienced from their previous supplier.               

Q.   Why are Mainline Dyno’s more consistent than other brands

A.    From its inception, the Mainline DynoLog Dyno was always a step ahead of its competitors. The complete system was better thought out from the very beginning when at the drawing board stage; like incorporating an automatic weather station for environmental power correction, fitted as     standard on every dyno unit. Unfortunately on lesser brands, this was not initially implemented or considered, so band aid measures like having the operator manually input weather data every hour an attempt to gain consistency of results. This eventually led to the operator then being in full   control of what power the dyno “shows”, so an unscrupulous operator could then make a vehicle show more or less power than what was actually measured.

We also do not base our testing on the mass of the vehicle under test, as this type of operator input provides the operator with the means to influence the measured results, whether entering incorrect mass data, or deliberately entering a lower vehicle mass for the test.

Our philosophy, from the very beginning, was to prevent the operator from entering any data or any correction factors that could influence the results. This is why a Mainline Dyno is considered more consistent and repeatable, than other brands on the market.

Q.   Why does a Mainline Dyno seem more expensive than some other brands?

A.    The concept of cost is very hard for a first time dyno purchaser to put into perspective. They initially perceive that all dyno’s will generally indicate how much horsepower a vehicle/engine has. What is not initially appreciated is the inbuilt standard features of a Mainline Dyno. For example, every Mainline Dyno ever sold, has user vehicle cooling fan control, which is simply controlled remotely by the operator simply pressing a key on the dyno’s wireless controller keyboard. The control of the vehicle cooling fan can also be set via road speed parameters. The benefit of this feature for example, will save the user hundreds of hours over the life of the dyno. Imagine  crawling into a drift race car, around all the rollbars, wedging yourself into the seat, then realising your haven’t  turned on the vehicle cooling fan, then having to extricate yourself back out of the vehicle and walk over to the wall to turn on the fan! This is what users of less expensive dyno systems have to put up with, every day for the life of their chosen system.

 Likewise, we have always fitted load cell and retarder cooling fans, and again, these can be manually controlled, or automatically triggered by road speed. In order to control these two items, the necessary high voltage electrical switchgear is housed in the dyno control cabinet, eliminating the need for additional 3 phase outlets for vehicle cooling fans. This capability costs more to manufacture, and it ultimately adds to the overall cost of the dyno. A lesser system that seems cheaper because they don’t have the means for automatic vehicle fan control, quickly becomes more costly when it is found out an additional 3 Phase Outlet and associated wiring and circuit breakers are then needed to run the vehicle cooling fan, plus the hassle and downtime continually having to turn the fan on and off at a wall outlet.

Having an automatic weather station, as standard, also adds to a higher purchase price, but it means from the time that dyno is switched on of a morning until it is turned off at night; the dyno is continuously updating the correction according to weather conditions. On a cheaper dyno where a user can only enter weather conditions manually means the operator continuously update the data to ensure a consistent testing environment. Unfortunately, manually entered weather conditions too often are set once in the morning when first turned on, then forgotten about for the rest of the day, and then the user wonders why the car isn’t making the same power in the hotter afternoon conditions it did in the cooler morning.

The Mainline Dyno also has unrivalled data acquisition capabilities, from the standard 88 channel data logger included with the control system, to more than 250 + supported external devices that can   interface to our system. A Mainline is the future proof dyno! Lesser units are designed with very limited inputs, features and functions to cut manufacturing costs; however they quickly become obsolete due to lack of future hardware or software upgrade solutions, or function expansion to cater for more advanced testing capabilities, as advances in vehicle technology are made. This is one of the most common pitfalls of only considering the initial purchase price, especially for a first time buyer.

There are numerous other reasons that will easily justify why a Mainline Dyno is an excellent investment as a long term solution for your tuning and diagnostic needs.  A personal demonstration is required to really appreciate not only what a Mainline Dyno can actually do, but what it is it actually “worth” to your business.  The majority of our sales are actually to experienced  dyno users that have previously purchased other brands and unfortunately found out the hard way what a liability that an inadequate dyno system can be to any business.

We also enjoy a high level of repeat business from our existing customer base. We have never lost any  Mainline Dyno owners to other dyno brand, which is a claim that many other manufacturers cannot make.

Our active research and development program has regular dyno program updates available for any of our customers, so their investment will not stagnate and become obsolete. Having an up to date system will also keep your dyno productive and profitable. Many lesser dyno systems do not offer any regular software program updates or provide an update path for the original equipment.
