Fuel Economy Tuning

With the rising price of fuel, fuel economy is a major factor in the survival of trucking companies.  We offer a "Tuning" service that will not only lower your fuel cost, but also give more power to your diesel engine.

ECM Tuning

With more than 5000 truck tuned each year, Diesel Spec is the Canadian leader in diesel engine performance.

ECM tuning is the process of fine tuning the software program that controls your engine fuel management system, without having to replace any part.  The result: more power, greater response and lower fuel consumption. What’s more, fine tuning an ECM has no negative impact on exhaust emissions orengine life. In fact, optimal tuning of your engine will reduce your maintenance cost, since an engine with better combustion is a cleaner engine.

We offer tuning for Cummins, Caterpillar, Detroit Diesel, Mercedes,International, Volvo, Paccar, Mack and most agriculture engines.

We can help you reduce your fuel cost from 5% to 25%. An efficiency gain of 1 MPG on a diesel truck driven 200,000 km per year represents $12,000 in fuel cost reduction per year. For a fleet of 10 diesel trucks, that means $120,000$ saved per year.

All our Fuel Economy Tuning meet North American emission opacity norms. Diesel Spec offers in house opacity testing with devices authorized by the Canadian government.

Tuning has been very popular in Europe since the last 20 years, because of high fuel costs. Due to rising fuel prices in North America over the last decade, interest in tuning has been growing. To respond to that increasing demand, Diesel Spec has invest in tuning for diesel engines.

Safely improve power and torque. Need more horsepower and torque? We can fix your problem with our Performance tuning, which gives you up to 30% more power without having to replace any parts.

Off-highway tuning

In addition to its engine repair and tuning services that enhance the performance of diesel engines while ensuring fuel economy, Diesel Spec also offers off-highway tuning services to reach unmatched high levels of performance.

Diesel Spec offers off-highway tuning services for special applications such as competitions and events like drag racing and/or sled pulling. In most cases, engines used in competitions require modifications, including the replacement of parts and the removal of emissions components. We put at our customers’ disposal a variety of high performance Big Boss parts: Turbo Chargers, Manifolds, High Torque Clutches, and more. Newer engines require the removal of the Regen System. Our tuning alterations include EGR Valve Delete, DPF (Diesel Particulate Filter) delete, Urea system delete (DEF Fluid), VGT Turbo delete (Variable geometry turbo) and RPM limiter removal. By removing these components from your engine, you will significantly increase the performance of your diesel engine when using your heavy truck for off-highway purposes.

With the deletion and alterations of some of these performance parts, your engine can easily reach over 1000 horsepower.
 
Diesel Spec tuning examples:

• EGR valve delete
• CGI valve delete
• DPF delete
• VGT delete (Variable Geometry Turbo)
• SCR urea system delete
• SPEED LIMITER REMOVAL
• RPM LIMITER REMOVAL
• TWIN TURBO CONVERSION

There are many other tuning alterations that can be made to your engine. Tuning allows you to reach new heights when using your heavy truck for personal purposes or closed-course racing.

Custom tuning available for competition trucks and export trucks using high sulfur fuel.
 
Truck export to countries with high sulfur fuel

Most countries still use high sulfur diesel fuel. All North American trucks that were built from 2007 to date, equipped with an EPA07, EPA10 or EPA13 certified engine cannot operate on high sulfur fuel.  If they are using high sulfur fuel, their engines will only run approximately one week. During this time, the DPF will become completely clogged with soot/carbon and the engine will shut down.

Diesel Spec has the solution – completely cancel the after-treatment system (EGR-DPF-SCR). As a result, the truck engine will perform normally without having to go into derated or shutdown mode because of engine codes.

Most of our tuning work can be performed remotely all over the world with the purchase of Diesel Spec tuning tools. This means that you won’t need to ship your ECM to Canada and wait for a week. Therefore, you will save both on shipping costs and downtime. Once you are equipped with our DSI remote tuner, the tuning work can be done in just one hour.

Dynamometer

MD-1000 - The industry standard for tandem-axle heavy duty truck Chassis Dynamometers

The MD-1000 Series heavy duty truck dynamometer has a standard peak horsepower measurement capacity of 2,000 hp, enough to handle most standard trucks, including tandem axle Class Eight tractors. The standard MD-1000 includes two MDK-400 air-cooled eddy current power absorbers that give the power to absorb up to 1,200-hp intermittently. Additional power absorbing units are available to increase the loading capabilities of the MD-1000. In fact, the MD-1000 is available in multiple design configurations to meet virtually every possible testing scenario and to cover the vast majority of heavy duty vehicles.

Other features include a rugged, unitary frame and flexible tandem axle spacing. The precision machined rollers mean you can conduct sustained tests at highway speeds. With Mustang’s sophisticated software, you can design a wide range of tests including three-stage diesel lugdown – and provide both on-screen and print-out results. Controls include a wireless hand-held unit, so operators can control the test from the cab of the vehicle. Additional options available include PAU cooling fans to help keep the air-cooled PAU’s cool, additional axle sets, Variable speed engine cooling fans, and integrated diesel opacity meters.
