Why Choose an EQT Custom Flex Fuel Tune?

EQT Custom Flex Fuel Tunes aren't just a one-size-fits-all solution. It’s a tailor-made calibration specific to your unique setup, driving goals, and performance needs.

If you’re running advanced components such as our Vortex or Typhoon Turbos, or if your setup includes specialty fueling systems like multi-port injection or ethanol-specific sensors, a custom tune ensures every detail is dialed in for peak performance. Staged tunes provide a strong baseline, but custom tunes take your vehicle to the next level by addressing every nuance of your build.

Custom vs. Staged Flex Fuel Tunes:

Choosing between a Custom Flex Fuel Tune and a Staged Flex Fuel Tune depends on your goals, vehicle setup, and desired level of personalization. Here’s how they compare:

  • Staged Flex Fuel Tunes:
    Designed as pre-calibrated solutions, staged tunes are perfect for vehicles with common modifications like upgraded intakes, downpipes, intercoolers, and IS38 Turbochargers. These tunes deliver reliable power gains with plug-and-play simplicity, ensuring smooth operation for most standard setups. Ideal for enthusiasts seeking a quick, effective solution without needing extensive custom adjustments.
  • Custom Flex Fuel Tunes:
    For those pushing the limits with advanced setups—like larger turbos, port injection, or aggressive fueling strategies—a custom tune is the way to go. Custom tunes are specifically tailored to your exact modifications, driving style, and performance goals. This personalized approach unlocks maximum power, drivability, and reliability for vehicles with unique or heavily modified builds.

What Are The Benefits of Running Ethanol Flex Fuel Tunes?

  • Power You Can Feel: Ethanol’s higher octane rating allows for increased timing and boost, giving your engine the potential to produce significantly more power.
  • Seamless Adaptability: Ethanol blends like E10, E50, or E85 are all fair game, giving you the ultimate flexibility at the pump without sacrificing power and having to switch tunes.
  • Cooler Combustion: Ethanol burns cooler than gasoline, which helps reduce engine temperatures and minimizes the risk of knock, especially during high-performance driving.
  • Cleaner Burn: Ethanol burns cleaner, leaving less carbon buildup in the engine. This means a healthier engine and better long-term performance.
  • Cost-Effective Power Gains: Ethanol-rich fuels like E85 are often more affordable than premium gasoline, letting you enjoy top-tier performance without breaking the bank.

Frequently Asked Questions

Tuning Process

Live Tuning vs. Non-Live Tuning

Standard custom tuning typically takes several weeks and involves sending logs back and forth to the tuner. During this time, the car will be drivable; however, it will not be fully dialed in until the final revision is received.

With live tuning, a time slot can be set up with your calibrator to complete your full tune in one 2-3 hour session. We highly encourage that customers rent a dyno for this due to safety.

Disclaimers

Live Tuning

Customer acknowledges that if they are 15 minutes late to their session, a Late fee of $200 will be charged, if they′re 30 minutes late, the session will be cancelled, and a reschedule fee of $200 will be required before setting up another session.

Intake and Intercooler Setups

While other parts may work, we have found that the Blaze Atom V2 Intake and the do88 intercooler are one of the most optimised combinations for air flow on these platforms. If you prefer that we tune your car with alternative flow parts, please be advised that you may not achieve peak performance due to possible restrictions imposed by other mods. If you′d like to purchase them before getting started, please visit EQTuning.com, and once purchased, please submit an updated form. 

PM4 Fuel Pumps

The PM4 pump controller is required for any non-Brushless LPFP. We do recommend our Plug and Play brushless LPFP. However, if you prefer to run your own pump, be advised that non-brushless pumps require a PM4, or we will not tune them.

Why Tune With EQT?

  • Easy-to-use, handheld device for monitoring, logging, and flashing.
  • Flash your vehicle at home using the Accessport (does not need to stay connected to OBDII once the vehicle is flashed).
  • Quick map switching in as little as 60 seconds via Accessport.
  • Custom calibrations tailored for all climate conditions and elevations.
  • Increased rev limiter and speed limiter removed (dependent on TCU tuning).
  • Burbles (crackles, pops, and bangs) available below 4000 RPM and more aggressive above 4000 RPM.

About Our Tuning

The VAG MQB platform comes with incredibly sophisticated engine management systems from the factory. Working with these ECU's requires an intimate knowledge of engine dynamics and software engineering to be able to properly understand and modify the functionality. We have been working very closely with Cobb Tuning and EcuTek through the development of their tuning software for this platform. This close relationship gives us early access to the newest features and input into further development and refinement of the system. Using this software, we have spent the past few years developing and refining our tunes for your MQB Platform car. Countless hours of in house dyno testing, drivability road testing, and track torture testing went into the development of our calibrations. So you can be sure your car will perform optimally while retaining excellent drivability characteristics and a healthy margin of safety built into every tune.

We go way beyond the standard fuel, boost, and ignition adjustments that are common in the tuning world. We spent the time to go through and map out the complete torque control system, the complex ignition control and knock detection systems, the sophisticated turbo and airflow modeling systems, the fuel management and injection timing systems, and countless other parameters. The end result can be felt any time you drive the car on a track, a fun road, or even for your regular grocery run.  We also offer all the custom features from Cobb. These include our own customized traction control system, flat foot shifting, and burbles/crackles.

More About Custom E-Tuning

While our refined base map tunes are a great choice for cars with basic modifications, this custom e-tuning service takes over from there. This service is highly recommended for cars with heavier or more customized modifications like water/meth injection, upgraded turbos, upgraded fuel pumps, ethanol blends, race gas, etc. This is also a great option for those with basic modifications who want to get the absolute most out of their tune and to customize it to their specific goals, use, and driving environment.

How it works (the process)

When you purchase a custom e-tune, you will provide us with details about your car and setup. We will then craft and e-mail you a customized base map for your car that will work as a starting point for the process. You will then follow instructions to install the map on your car and gather data via logging which will be e-mailed to us for review. We will review and revise the tune, and then repeat until the tune is perfectly dialed in. The entire process generally takes 4-8 revisions, though we do not implicitly limit the number of revisions. We generally get revisions out within two weeks of receiving logs. The goal of every tune is to dial in the car as perfectly as possible and to customize the feel to the specific driver's preference. During the entire tuning process, you will have a clear line of communication with our expert tuner. 

Live E-Tune Session Information

Instead of going through the standard e-tune process which can take 3-8 weeks to complete, we also offer an option to schedule a Live Tuning Session with one of our tuners. The process for this is very similar in that we exchange logs and revisions until the tune is dialed in. However, with this option, we get everything done in one day over the course of 2-4 hours. Many customers choose to also schedule dyno time at their dyno facility of choice to help complete the tuning session. This can make the process even smoother and will provide a more dialed in result. The other option is to complete the required data logs on a safe closed road/track. In either case, the customer must have a reliable internet connection and must be able to perform logs in a timely manner. 

The Live E-Tune Session is included in the base cost of the tune. If you choose not to have a live tune session, standard revisions will be used.
