It’s a great time to own a muscle car, especially the 2015 Ford Mustang GT…arguably the most mod friendly car on the planet right now. It’s fast, handles well, loves boost, and has plenty of tuning options. And now, Amazon Tuning Solutions can make sure your Mustang GT is running in top form on both the street and on the race track. Introducing: FREE RACE FUEL TUNES!
Race fuel and a race fuel tune can be a lot of fun, but you do have to be careful which fuel you choose when you’re dealing with a modern vehicle, especially the 2011-2016 Mustang GT.
These mustangs run in “closed loop” constantly. In other words, the PCM is always monitoring Air/Fuel ratio to make sure you’re hitting the target AFR, rather than “forcing” in fuel values from an open loop table. This distinction is important: It adds consistency to the tuning process, but it does cause issues with leaded race fuel.
Why? Because it’s a known fact that leaded race fuel damages O2 sensors, and replacing them regularly isn’t a desirable option due to cost, inconvenience and potential inconsistency. We’re not dealing with a 50 year old car, so why should we use 100 year old fuel technology?
Fortunately, there are ultra high octane, unleaded race fuels that are perfect for your Mustang GT and our personal fuel of choice at ATS is Gulf Racing Fuel.
Our very own 2015 Mustang GT runs on Gulf Mach 116, a 116 octane (R+M/2) unleaded race fuel that delivers the power and safety margin we need at the track. Even if you don’t need 116 octane, Amazon Tuning Solutions can get you tuned at any octane level, from 87-116 and the Gulf Mach series of unleaded race fuel comes in 105, 110 and 116 octane levels, so there’s a flavor for every car, from mild to wild!
The race fuel blend: An economical and safe street & track car solution.
It’s long been a challenge to dial in a dual purpose street/track car without compromise. While running pump gas on the street and race fuel at the track sounds great on paper, what if you’re driving to the track? What if you still have 1/4 tank of fuel? What if you want to drive your car to work all week, then take off Friday night and head straight to the drags? How do you make sure your fuel mix is perfect? In short, you can’t..unless you’re draining your fuel tank every time, but this isn’t practical for a street car, so what is the solution?
Gulf Mach 116, with it’s non oxygenated, unleaded properties and similar stoich to pump gas, gives you the ability to run a BLEND of race fuel with pump 93, and The Amazon Tuning Solutions race fuel tune can be built to compensate for your blend.
For example, let’s say you buy an HP Tuners nGauge with a street 93 tune from ATS for your VMP Supercharged 2012 Mustang GT: Any reputable, experienced tuner can dial in a great 93 octane tune and, since pump gas is generally consistent, the knock sensors can compensate for the occasional “bad” tank of fuel, as oxygenation levels only vary a few percent. But how do you create a race fuel tune when you’re intending to run both race fuel and pump gas on the same day? Making this even more challenging is the fact that many race fuels are oxygenated and have a radically different stoich than pump fuel. Now we’re looking at a completely different Mass Airflow transfer function and any type of “blending” becomes irresponsible.
A solution that has worked for us is the “Gulf 105 tune”, which consists of either running Gulf Mach 105 full time, or creating a 105 octane tune that performs well on a blend of 93 octane and 116 octane, creating a 105 octane “blended” fuel in a 50/50 ratio.
How does this work in the real world? Simple! Let’s say you want to take your car to the track and run your 105 octane race fuel, but it still has half a tank of pump 93. We’ve found that Gulf Mach 116 unleaded is so potent, you can blend it 50/50 with pump 93 and make a great performing 105 octane fuel. And what happens if you miss the mark a little bit? Our tune can compensate for mild to moderate variances in octane, giving you flexibility to go to the track whenever you want. What this really amounts to is us tuning your car for 100 octane, where a race fuel “over fill” simply serves as an extra pad against detonation, but an under fill is still safe and within the acceptable octane range.
Gulf Racing Fuels are also available in hazmat-approved 5 gallon pails, making it easy for you to add fuel at the last minute for a night at the track. Then you can drive the car home, refill with 93 octane and switch back to your street tune using the HP Tuners nGauge–all without cables in your lap or needing to remember to take your programmer with you. The nGauge mounts right on the dash and blends in with Ford’s design.
