Standard Features

Standard - Accurate, Dependable, Repeatable Results

The Mainline/DynoLog Dyno is widely described as the "No Fudge" or the "Unfudgeable" dyno, and is the obvious choice for dyno operators who choose an honest approach to business and do not want to be caught up in the debacle about why the same car can get differing results on the same brand of dyno, why the same car can produce inconsistent results using different dyno "modes" or even why a dyno needs different "modes" for 4, 6 and 8 cylinder vehicles.


The Mainline/DynoLog Dyno deserves its outstanding reputation for producing the same results from dyno to dyno, as a scientific approach has been taken that provides the highest degree of accuracy.  No need for a special operating mode that reduces the ability of the operator to affect the results.  No need to pay expensive annual fees for special training or certification to join a "club" of operators whose dyno results are alleged to be more accurate and believable.  No need to have to add your signature to your printed dyno sheets to try and convince people that the results are accurate or believable.  No inbuilt options where the dyno operator can "modify" results.  Definitely no embarrassing cheat modes and no smoke and mirrors on the Mainline/DynoLog Dyno.

The Mainline/DynoLog Dyno is designed to produce only accurate results.  So for simply accurate, dependable and repeatable results, time after time, the Mainline/DynoLog Dyno is the obvious choice.

Standard - Deluxe Computer Control Workstation

As a standard dyno inclusion we provide our visually pleasing fully enclosed, (full steel construction), amazingly functional deluxe workshop cabinet.

The Deluxe Workshop Cabinet comes complete with wheels, plus boom arm & nudge bar assemblies, and provides safe storage for all computer components, printer and Dynamometer accessories/electronics.   Power to the control components is supported by an Uninterruptible Power Supply so that critical data is not lost in the event of a power failure.  And no upgrade option is necessary for your monitor.  A 22" LCD monitor is provided as standard, and a dual monitor option is available that is particularly useful for torque optimisation, MBT, emissions testing, combustion analysis etc.  The Dual Monitor Option (pictured right) also expands the range of data channel graphs that can be viewed simultaneously to a maximum of 12.


Standard - In-Car Wireless Keyboard/Trackball Controller

No need to clutter up the vehicle with a Hand Controller AND a Keyboard.

The Mainline/DynoLog Dyno allows all Dynamometer functions and tests to be accessed and controlled using the mini keyboard/trackball controller.  Your dyno is initially delivered with cordless keyboard/trackball combination.  If you prefer, your dyno can be set up to be fully controlled from a remote laptop or a USB corded keyboard/trackball.  And unlike a hand controller, if your Keyboard/Trackball ever ceases to operate simply plug in a PS2 or USB Keyboard and Mouse as a temporary measure so that you do not lose valuable dyno time.

Replication features are provided for operators who are used to using other dynos.


Standard - Heavy Duty Chassis Construction

The Mainline/DynoLog Chassis Beds are of heavy-duty construction, and extremely resistant to any flexing or harmonics from the test vehicle. Each “S” Beam Load Cell is suspended between two opposing rod ends ensuring it is not subjected to any environmental heat or flexing influences and remains free of tension.

The standard Mainline/DynoLog Dyno beds utilise 217mm or 270mm rollers with optimum deformation knurling that maximises traction whilst minimising tyre distortion and noise and ensuring a more accurate Speed and Power reading.  The Mainline/DynoLog Dyno is also available with retarders and load capacity to suit virtually all applications.


Standard - Highest Quality Retarders

We will never compromise quality, and your Mainline/DynoLog Dyno will be equipped with the best quality retarders available in the world today (Frenelsa). Be wary of manufacturers that use the cheapest available retarders which typically cost only a fraction of the cost of our retarders and are of significantly lower quality.  Cheaper retarders also tend to have significantly less load-holding capacity.  Mainline/DynoLog opts for only the best, and will not compromise the quality of any of the components in its products.

The smallest retarder that we use has a maximum torque rating of 1,700Nm and while the retarder is rated at 850kW (1134hp) at 200kph. 

We offer the option of a second 1700Nm retarder in the same dyno bed to double the rated capacity to 1700kW (2279hp).

The retarder is the “workhorse” of the dyno, and the quality of the retarder will be a reflection of how much trouble-free life your dyno is likely to provide.  Would you rather your dyno was fitted with the best quality retarder available in the world, or the cheapest retarder available, especially if the difference is not reflected in the dyno pricing?


Standard - Highly Accurate Roller Speed

The Dynamometer Roller speed is measured using a digital sensor, ensuring exceptionally accurate roller/vehicle speed measurements.


Standard - Vehicle/Dyno/Dyno Cell Fans & Fan Control

Vehicle Fan control is achieved via a 3 phase power outlet mounted on the side of the cabinet assembly to apply power to the optional Vehicle Cooling Fan.  The Vehicle Fan is manually controlled by the operator via the keyboard or alternatively programmed for automatic operation. Mainline/DynoLog Dyno beds are fitted with fans to cool the load cell & retarder, and the fan operation is programmable or manually controlled by the operator from within the vehicle.  Mainline/DynoLog software supports VSD (Variable Speed Drive) for control of Dyno Cell and Vehicle Cooling Fans.  The user can program the vehicle cooling fan speed and/or dyno cell fan speed to simulate on-road air flow.


Standard – (AWD Models) Software Wheelbase Adjustment

Yet another example of the sheer superiority and professionalism of the Mainline/DynoLog Dyno, and another first in the world of chassis dynos, our All-Wheel Drive Series Dynos are equipped with software driven bed adjustment to provide “spot on” adjustment for different wheel base dimensions.  No need to hold a switch to adjust the dyno wheelbase and visually guess the correct wheelbase.

Definitely no need to use a marking pen or unsightly pieces of tape on the adjustment frame to try and get consistency.  The Software Wheelbase Adjustment system only requires the user to select the vehicle from a menu, and the dyno wheel base will be automatically adjusted to within a 1mm tolerance – every time.

Of course the system allows for manual adjustment if needed.  The software has a database of vehicles and wheelbases, and the user can Add, Delete or Edit vehicle data.  Safety is paramount, and the system can activate a warning siren prior to moving the dyno bed.  This feature of the Mainline/DynoLog Dyno provides for a new level of repeatability and ease of setup, and a giant leap forward in dyno professionalism!


Standard - High Resolution Graphics

Mainline/DynoLog Dynos offer seamless graphics processing and printing using the Microsoft Windows Graphic User Interface, and provides the highest resolution graphics for viewing on screen or printing.

The Mainline/DynoLogdyno clearly sets the benchmark for quality graphical output and for genuine, honest results.  Unable to provide proper high resolution graphics, some other dynos use simple low resolution screen dumps which look good on screen but lose definition when printed.

Mainline/DynoLog also offers built-in support for automatic watermarking and barcode operation.  Automatic watermarking is available through an interfaced digital camera which will photograph the vehicle on the dyno and automatically include the photo (or any other graphical image) as background for the customer graph.


Standard - Advanced Diagnostics

Mainline/DynoLog Dynos feature advanced diagnostics that other manufacturers can only dream about.  New operators who have only previously used competitor’s dynos are constantly telling us that our system opens their eyes for the first time about what is really going on within a vehicle.

Our range of optional advanced diagnostics provides you with the data you need to make YOU the expert, and many of our advanced diagnostics can be added at any time.  Even more importantly, the Mainline/DynoLog control system software is being constantly updated and improved so that it will continue to lead into the future.

Check out the incredible range of diagnostic options that we offer already.  The Mainline/DynoLog Dyno is the world leader in dyno technology, and we guarantee that our competitors will be playing catch-up for a very long time.

Standard - Advanced Diagnostics - Pressure Delta

Allows measurement of pressure drops through the inlet system (air box – intercooler – Mass Air Flow Meter – Engine) during steady state testing, to determine the extent of restrictions in the inlet tract.

All logged pressure channels can be zeroed/compared against Barometric pressure to show instantaneous pressure variations during steady state tests.


Standard - Advanced Diagnostics - RPM Tables

Yet another exceptional means of analysing data.  RPM Based Channel Tables display data from any logged, calculated or maths channel against engine RPM rather than road speed. Compare up to 10 data channels at any time including Lambda and Target Lambda Correction, plus Boost and Target Boost Correction.  The user specifies the tacho source to be used for plotting the data, and the RPM Steps (each 50, 100 etc) for the viewed data.


Standard - Advanced Diagnostics - Target Boost Correction

During mapping, it is also usually necessary to specify how much boost is required in percentage terms to achieve a target boost pressure.

For example, at 5,000rpm an engine may require more boost to achieve 1.3 Bar.

Mainline/DynoLog will calculate the actual percentage required from logged boost data, and the operator need only add that percentage boost.  This feature also dramatically speeds up the tuning process, and again minimises engine running time during tuning.


Standard - Advanced Diagnostics - Target AFR/LAMBDA Correction

When mapping vehicles, it is usually necessary to specify how much fuel change is required to the fuel map in percentage terms to achieve a target Lambda.  For example, at 5,000rpm an engine may need more fuel to achieve a Lambda of 0.86.  Mainline/DynoLog will calculate the actual percentage required from logged Lambda / AFR data, and the operator needs only add that percentage fuel to the ECU or PCM or carburettor.  This feature dramatically speeds up the tuning process for both carburettor and injected vehicles, and minimises engine running time during tuning.   The operator can choose a single value target AFR or have Mainline/DynoLog derive a target value from engine RPM and Manifold Pressure.  The operator can pre-set a table and Mainline/DynoLog will look up the appropriate target for the RPM position and Manifold Pressure from the table.

The operator can also define a target AFR value for any fuel type and have a visual indication on the graph screen as shown here. The white line is the defined target AFR and the light blue line is the actual logged AFR value during a ramp test.

A recent addition to this function now includes a popup zoom window to show the selected data in large font, easily viewable from inside the test vehicle. In the following example, the target AFR is set to 12.50:1, @ 2900 RPM. The required fuel change is to remove 4.25 % of fuel to reach the desired target fuel AFR value.

In this example the operator has clicked on the target fuel correction required at 2900 engine RPM. This quickly shows the operator the correction required (- 4.25 %) to correct the current AFR value (11.92: 1 AFR) to the desired target fuel value (12.50: 1).

As many aftermarket ECU tuning software programs only display a numerical value for fuel quantity, the Mainline/DynoLog now includes an ECU fuel table calculator. This function allows the dyno user to enter in the numerical value displayed in their aftermarket tuning software fuel table and the Mainline/DynoLog software simply calculates the revised numerical value to edit the fuel table value to.

In this example, the dyno operator has entered in a fuel table value of 876 from their tuning software fuel table. The Mainline/DynoLog software calculates, and indicates to the operator, the numerical value (838.8) required to achieve the target AFR of 12.50:1.  The operator edits the tuning software value to the new corrected value to achieve the desired target AFR for this RPM interval.

The operator/tuner would simply change “876” fuel table value to “838.8” and the AFR should be on target at that tune site.  This function can vastly speed up the time required to tune the engine to the desired AFR value throughout the engine RPM range.  This advanced function is a standard feature of the Mainline/DynoLog system.


Standard - Advanced Diagnostics - Maths Channels/Calculated Channels

200 User Definable Maths Channels - Mainline/DynoLog Dynos feature user-definable maths channels that can be used to perform calculations from other data channels and display user information.  For example, Radiator Temperature Gradient – derived from Radiator Inlet Temperature minus Radiator Outlet Temperature, or Transmission Slip – derived from Engine Tacho and Vehicle Speed (derived from OBD-II or ECU data).

100 Calculated Channels - Mainline/DynoLog has a further 100 Calculated Channels set aside for hard coding of user requirements.  Several of these channels are already allocated, including Torque Converter Efficiency, which compares torque converter efficiency between individual test runs, Injector Pulse Width, Maximum Available Pulse Width, Pressure Drop (Intercooler Loss), Injector Frequency, Wheel Power & Tyre Loss (OBD-II Option Required)


Standard - High level Data Analysis

The ability to analyse data from the advanced diagnostics sets the Mainline/DynoLog Dyno even further apart from ordinary dynos.

Most competitor dynos have no analytical functions in their software at all.

Each of the 500+ Mainline/DynoLog data channels can be graphed and viewed as raw data, including the calculated and maths channel data, and up to 6 runs can be overlaid for analytical purposes on up to 12 different channel graphs.

Data Fly Boxes allow quick assessment of graphed data, and the operator can view and analyse data from virtually any angle.  A few clicks on the keyboard can provide you with data averaging, differences between runs, raw data viewing, Max/Min Speed at Max/Min Data, run averaging, difference graphs, difference tables, channel integral etc. A few more keystrokes can provide you with your average torque and power between your peak torque and peak power.

The analytical capacity of the Mainline/DynoLog system is so advanced that it requires a personal demonstration to come to terms with its capabilities.


Standard - High Level Data Analysis - Data Smoothing

Several levels of graphical data smoothing are available to allow easier interpretation of data. The operator can choose the level of smoothing to be applied to each individual channel or to be applied globally.  Moving average or Savitsky-Golay algorithms are used.


Standard - High Level Data Analysis - Viewing “LIVE” Vehicle Data

The Mainline/DynoLog Dyno also stands apart from other dynos in this area.

Power, Torque & Speed can be viewed in digital or analogue format, a scrolling chart recorder provides a timeline for 3 user-selected data channels at a time, there are 20 pages of user configurable channel data that can be viewed live at any time, and 8 test monitor channels can be viewed concurrently while graphing a ramp test.  All available data channels including Air:Fuel Ratio and Boost can each be viewed as a live trace drawn over user configurable limit lines so that any variation is immediately obvious.  On vehicles equipped with OBD-II, live OBD-II data can be viewed in real time using our optional OBD-II Data Logging Kit.

When using the optional ECU Data Logging Kit, the live ECU data can also be viewed in real time.  In fact, virtually any data input from any data source can be viewed in real time, including OBD-II, ECU, Gas Analyser, Fuel Flow/Pressure/Temperature and Diesel Opacity.


Standard - High Level Data Analysis - Visualise Timing Events In Engine

An inbuilt calculator allows visualisation and personal analysis of timing events (ignition, injection, cam timing) in an engine.  This handy feature simplifies understanding of the complexities of the combustion process.


Standard - High Level Data Analysis: Export Data To Text File Or MS Excel

All data logged during runs can easily be exported to CSV text files or to MS Excel for further analysis or to use MS Excel’s 3D Graphing Modes and other advanced features.  For advanced users, Dyno Data can be sent via Ethernet or RS232 to external PC’s running Microsoft Excel where the user may have specific spreadsheets storing dyno output data for analysis.


Standard - Safety Alarms

The Mainline/DynoLog software features alarms that can be set to warn the operator if operating parameters are exceeded so that potentially dangerous situations can be avoided eg. RPM, Speed, AFR, Boost etc.  The system also has an optional alarm to remind the operator to remove the AFR probe prior to driving the vehicle off the dyno.


Standard - Print Directly To PDF & JPG

Mainline/DynoLog Dyno software includes the ability to print to hard copy for viewing or to PDF or JPG for emailing.


Standard - Digital Camera Support

With just a few clicks or keystrokes, the user can use our built-in support for automatic watermarking and photo backgrounds.  An interfaced digital camera will photograph the vehicle on command and automatically include the photo as background to the customer graph.


Standard - Elapsed Time Meters

Mainline/DynoLog software includes a series of elapsed time meters which record Total Dyno Hardware Hours (absolute), Dyno Hours (Resettable) and “on song” Dyno Hours.  The elapsed time meters are also useful for tracking rented dyno usage time.


Standard - AWD Ready Software On 2WD Systems

For our clients with 2WD Mainline/DynoLog Dynos who may use another client’s AWD Dyno, we provide the means whereby they can transfer the AWD run data onto their 2WD system and analyse it on their 2WD Dyno.


Standard - Laptop Ready Software

The Mainline/DynoLog software system can be remotely controlled from a laptop within the vehicle via a cable/wireless network link if required.


Standard - Network Printer Support

The Mainline/DynoLog software supports networked printers.  Printers are selectable from within the Mainline/DynoLog software.

Users may easily and quickly open other external software packages such as Calculator, Notepad, MS Word, MS Excel, Convertetc from within the Mainline/DynoLog software.


Standard - Total User Configurability

The user is free to configure each Data Channel according to personal preferences.  For example, Manifold Pressure can be displayed as KPa, PSI, ATM, Bar, Millibar, InHg, InWater, and either Absolute or Gauge.


Standard - Centre Differential Testing

Mainline/DynoLog software normally controls the speed of the front and rear wheels of AWD vehicles within extremely close tolerances, however it also includes a mode where the operator can deliberately unbalance the front and rear wheel speeds to test the centre differential.


Standard - Fuel Injection Sizing Calculator

Users can calculate the maximum injector flow rate required to achieve any given power level, or the power level that can be achieved from a particular injector flow rate.  This option can be used for Naturally Aspirated or Forced Induction engines and Specific Fuel Consumption.  The user specifies the number of injectors, maximum duty cycle allowed, plus the fuel type and the Brake Specific Fuel Consumption and Mainline/DynoLog calculates the maximum Injector Fuel Flow Rate and the Power that can be achieved.


Standard - Air Flow Calculator

Soon to be released is our Air Flow Calculator which calculates engine air flow requirements from engine displacement and RPM.  This is ideal for ensuring that throttle bodies etc are capable of providing sufficient air flow to meet the requirements of the engine.


Standard - LAMBDA/AFR Calculator

Another useful standard inclusion is a calculator that allows Lambda values to be calculated from AFR, and AFR Values to be calculated from Lambda, plus a lookup table for all common fuel types.


Standard - Gear Change Point Calculator

The Mainline/DynoLog control system includes software to calculate the optimum gear change points based on best average power and best average torque.  This is an extremely useful function for extracting the best performance from your vehicle.
