Owner Matt Robinson augments the factory auto octane adjustment strategy in a way that allows considerably more power to be made as you step up your octane rating (without changing the tune).įor full disclosure, we’ll note that the truck’s stock baseline power numbers were collected after all ECU calibration changes (tuning tweaks) had concluded. But, not only does Gearhead keep this feature, they improve it.

This feature allows the ECU to self-adjust according to the type of fuel being used (be it 87, 90 or 93 octane, etc.). Perhaps the most important aspect included in Gearhead’s tuning package is its retention of the factory “auto octane adjustment” feature present in the ECU. So what happens if you get a bad tank of gas or simply can’t get the good stuff when you take a trip? Frequently, aftermarket ECU tunes require a certain octane rating and don’t take into account the fact that you may not always be able to run that same octane rating in your truck.

During each test, the Select-Shift six-speed automatic transmission was left in Fourth gear throughout the duration of the run (1.14:1 gear ratio).Īs we all know, 93 octane isn’t available at every gas station across the country - and even your local filling station doesn’t always receive consistent batches of fuel. For back-to-back, direct comparison results, all dyno testing was once again performed on Gearhead’s in-house 15000 series, all-wheel drive Dynocom chassis dyno. This ’16 model year, 12,000-mile 3.5L EcoBoost-powered F-150 was the test mule used for all of Gearhead Automotive Performance’s tuning R&D. This installment is the direct result of months’ worth of R&D conducted by the folks at Gearhead in an effort to make the 3.5L EcoBoost even more enjoyable to drive. We’ll strap a ’16 F-150 test mule to the dyno, upload a performance calibration onto the ECU, measure the gains of running higher octane and even see if there are any gains to be had from installing an aftermarket cold air intake system.

Once again working alongside Gearhead Automotive Performance, this edition of our EcoBoosted series unveils the hidden horsepower potential of the 3.5L - and the ease at which it can be unleashed. Combining parallel turbochargers (one turbo feeding each bank), direct-injection and high compression with precise electronic controls overseeing the powertrain, it didn’t take long for calibrators to unlock big power gains with a few simple ECU tweaks. In the aftermarket, the design of the engine didn’t go unnoticed. As more and more consumers learned how capable the twin-turbo 3.5L V6 was (outpacing its V8 rivals in virtually every meaningful statistical category), they welcomed the possibility of having V8 power with V6 fuel economy. In late 2015, the take-rate on EcoBoost-powered Ford F-150s was higher than 60 percent.
