Frequently Asked Questions
Question 1: What’s the best tuner for my 6.7 Cummins if I prioritize fuel economy over performance gains?
If you’re focused on fuel economy, look for a tuner with dedicated “economy” or “mileage” tunes. These tunes typically reduce throttle sensitivity and optimize fuel delivery for efficiency, sometimes at the expense of peak horsepower. A tuner like the Edge Insight CTS3 with economy tuning options or a Banks Derringer with its mileage-focused power levels are good choices.
Question 2: What are some important considerations when choosing a tuner for my 6.7 Cummins with a stock transmission?
When using a tuner on a 6.7 Cummins with a stock transmission, avoid aggressive tunes that dramatically increase horsepower and torque. Stock transmissions can struggle with the increased power, leading to premature wear or even failure. Opt for milder tunes that provide a noticeable boost without exceeding the transmission’s limits, and consider monitoring transmission temperature.
Question 3: How often should I update the tunes on my 6.7 Cummins tuner?
It’s a good idea to check for updates to your tuner software and tunes periodically, especially if you notice changes in your truck’s performance or if the manufacturer releases new versions. Updating ensures you have the latest features, bug fixes, and improvements, and can optimize performance for your specific setup.
Question 4: Can I use a tuner to diagnose problems with my 6.7 Cummins engine?
Many tuners, especially those with monitoring capabilities like the Edge Insight CTS3 or the Bully Dog GT Diesel, can read and clear diagnostic trouble codes (DTCs). This can help you identify potential issues with your engine before they become major problems, and can save you money on diagnostic fees at a repair shop.
Question 5: What’s the difference between a “canned” tune and a “custom” tune for a 6.7 Cummins?
Canned tunes are pre-programmed tunes that come with the tuner, designed for a range of vehicle configurations. Custom tunes are tailored to your specific truck and modifications, often created by a professional tuner based on data logs from your vehicle, offering potentially better performance and efficiency.
Question 6: Will a tuner void my 6.7 Cummins warranty?
Using a tuner can potentially void your factory warranty, particularly if the dealer can prove the tuner caused a failure. Most manufacturers frown upon modifications that increase engine output. It’s always best to check with your dealer or read your warranty documentation carefully to understand the risks before installing a tuner.
Question 7: Besides performance, what other features should I look for in a tuner for my 6.7 Cummins?
Beyond performance gains, consider features like real-time monitoring capabilities (EGTs, boost, etc.), data logging, and the ability to adjust parameters like tire size or speed limiter. User-friendliness, screen size and clarity, and overall interface are also important considerations for ease of use.
Question 8: How important is exhaust gas temperature (EGT) monitoring when using a tuner on a 6.7 Cummins?
EGT monitoring is crucial when using a tuner on a 6.7 Cummins, especially with higher performance tunes. Excessive EGTs can damage your turbocharger and engine components. A tuner that displays EGTs, or the addition of an EGT gauge, allows you to monitor temperatures and avoid potentially harmful conditions by adjusting your driving or tune settings.
