Our test vehicle was an '08...
Our test vehicle was an '08 Ford F-250 Super Duty with the 6.4L Power Stroke. Strapping it down to the Superchips dyno to obtain the initial horsepower and torque readings was the longest part of the process.
One of the most useful innovations to the modern automobile was the implementation of second-generation onboard diagnostics (OBD-II) in the '96 model year. A small plug under the dash of all vehicles allows us to interface with the vehicle's computers and monitor the powertrain in ways a mechanic in the '80s could only dream of. Now, we can pinpoint problems and be well on the way to a solution without even opening the hood. More importantly to the enthusiast, the addition of OBD-II opens up a whole new round of almost instantaneous performance enhancements, once again with hands clean, and the hood still closed.
Dozens of aftermarket companies have created tuners designed to eliminate many of the compromised settings dialed in by the vehicle manufacturer. Horsepower gains are often immediately felt, but that's only half the story. Now you can also modify or eliminate the rev-limiter on the engine, tighten shift points in the transmission, and adjust your speedometer to compensate for that new set of taller tires. Originally, tuners were designed for specific vehicles and retailers who had to have dozens of units on hand. Thankfully, technology keeps making it easier, and Superchips' new Cortex tuner has made it even easier.
The Superchips Cortex tuner...
The Superchips Cortex tuner box contained the unit along with an OBD-II connection, USB cord for Internet upgrades, and a brief instruction booklet. The installation simply required you to plug the Cortex unit into the truck via the OBD-II connector under the dash.
One Tuner, Multiple Vehicles
The $429 Superchips Cortex tuner features tuning that works with both diesel and gas engines. With the Cortex you can upgrade your Dodge, Ford, or GM diesel work truck during the week with an additional 100 hp and 200 lb-ft of torque. At the end of the week, you can return the truck to stock, and using the same Cortex, upgrade your Charger, Mustang, or Camaro for the weekend drag races. Then on Monday morning, you can return your car to stock and reprogram the truck in a matter of minutes. Horsepower gains are said to vary with the make and model, but the Superchips website will give you a close approximation of what you can expect.
In addition to adding horsepower, the Cortex has a data logging function that provides real-time information on functions like engine, transmission, exhaust gas temperature, boost, top speed, and 0-to-60 acceleration times. Superchips even has a prototype bracket in the works that will hold the programmer on your windshield or dash, eliminating the need for an additional gauge package.
