Mastering Fuel Change On Acceleration With Bama Tuner

Bama Performance offers a wide range of custom tunes for car enthusiasts, including the Bama E85 Flex Fuel tune. The Bama tuner can be adjusted for various parameters, including spark, WOT FUEL, and axle ratio. When adjusting fuel on acceleration, it's important to consider factors such as fuel injectors, throttle body changes, and lambda readings. Users can connect their Bama tuner to a computer and use the SCT Device Updater software to load custom tune files. However, it's recommended to consult with a Bama Tuning Experience Specialist for specific adjustments to ensure optimal performance and safety.

Bama tuner's adjustable parameters

Bama tuners offer a range of adjustable parameters that can be modified to enhance vehicle performance and drivability. The specific adjustable parameters can vary depending on the vehicle's year and model, but here are some of the most common ones:

• Tune Type: This includes options such as Street, Performance, and Race Tunes. Each tune type is calibrated to deliver optimal performance for different driving conditions and styles.
• Vehicle Speed Limiter: The tuner allows adjustments to the vehicle's speed limiter, providing flexibility for different driving scenarios.
• Tire Size Adjustment: Bama tuners enable modifications to tire size settings, ensuring accurate speedometer readings and optimal performance after changing tire sizes.
• Spark Settings: For SCT tuners, you can adjust spark settings in different RPM ranges, including Spark 0-2000, Spark 2000-4000, and Spark 4000-8000. These adjustments fine-tune the spark timing for improved engine performance.
• WOT Fuel: This parameter allows adjustments to the fuel delivery during wide-open throttle (WOT) conditions, optimizing fuel usage for maximum power output.
• Axle Ratio: The axle ratio settings in the tuner help match the gear ratio of the vehicle's axle to ensure accurate speedometer readings and optimal performance.

It's important to note that the available adjustable parameters may differ based on the specific Bama tuner and vehicle combination. Additionally, Bama offers custom tunes and a Free Tunes for Life program, allowing users to modify their tunes based on vehicle modifications or preferences.

How to load a new tune

To load a new tune onto your Bama Tuner, you will need to follow the steps outlined below.

Firstly, if this is your first time connecting the tuner to your computer, you must first visit www.sctflash.com and select the image of your device from the Tech Support tab. Then, download and install the SCT Device Updater. Using the provided USB cable, connect your device to your computer and wait for the drivers to install.

Next, you will need to save your custom tunes from your email to your desktop. Open the SCT Device Updater software and select 'Load Custom Tune File' from the Basic Operations menu. Click on 'Locate Custom Tunes' and select the desired tune from the list. The selected tune will appear under 'Available Tunes' in the left window within the Updater.

Transfer the tune to the X4 using the arrow button in the middle of the SCT. Press 'Program' when you are ready to transfer the custom tune to the X4. Repeat the previous two steps if you wish to load more than one custom tune file.

Now, you can head out to your car and put the BAMA custom tunes on your vehicle. Plug the BAMA X4 into the OBDII port of your car and select 'Program Vehicle' from the Main Menu. Press 'Continue' to accept the disclaimer and follow the device prompts to cycle the key to the ON position to set up the device for flashing.

Choose your desired tune from the main menu and click 'Continue' to acknowledge that the pre-loaded tunes will be disabled. Follow the device prompts to cycle the key to the ON position once again. The tuner will unlock the PCM, save the stock tune to the device, and count up to 100%. It will then write the custom tune to the PCM and count up to 100% again.

Finally, follow the device prompts to cycle the key to the ON/OFF position to complete loading your custom tune.

Running lean

In the context of a Bama Tune, a "running too lean" code may be triggered by a loose cold air intake (CAI) elbow, which can allow unmetered air to enter the engine. This can usually be fixed by tightening the elbow and the throttle body (TB).

If the issue is not related to a loose CAI, it may be due to a fuel pressure problem. In this case, it is recommended to datalog your fuel pressure drop across injectors to identify any discrepancies.

It is important to address a "running too lean" code promptly as it can cause significant engine damage if left unchecked.

Lambda of .84 at WOT

A Lambda of .84 at WOT is good.

If you want to know how to change fuel on acceleration with a Bama tuner, you can adjust the WOT Fuel parameter. However, the adjustable parameters vary from vehicle to vehicle, so you should consult a Bama Tuning Experience Specialist to ensure you are making the right adjustments for your specific vehicle.

To put a new tune on your Bama tuner, you will need to:

• Visit www.sctflash.com and click on the Tech Support tab.
• Select the image of your device, then download and install the SCT Device Updater.
• Using the provided USB cable, connect your device to the computer.
• Save your custom tunes from your email to your desktop.
• Open the SCT Device Updater software and select "Load Custom Tune File" from the Basic Operations menu, then click on "Locate Custom Tunes."
• Select the desired tune from the list of tunes.
• Transfer the tune to your device by using the arrow button in the middle of the SCT.
• Press "Program" when ready to transfer the custom tune.

Please note that you may need to adjust some options when loading a new tune. If you have any questions or need assistance, it is recommended to consult a Bama Tuning Experience Specialist.

Fuel injectors

When dealing with fuel injectors, it is important to provide specific details about the injectors to ensure the best tune for your vehicle. This includes the flow rate in pounds per hour and the manufacturer's part number. If you are unable to provide this information, a link to the product can also be helpful. Bama Performance supports a range of fuel injectors, including Ford Performance (Racing), Injector Dynamics, Siemens Deka, and Bosch.

The Bama Performance Tunes for Life program offers support for common bolt-on items, with fuel injectors being one of the most common parts they work with. They also provide support for other modifications, such as cold air intakes, throttle bodies, gear and tire changes, and more. It is important to note that Bama Performance does not support all modifications, and certain restrictions apply. For example, they do not support aftermarket superchargers, turbochargers, or engine swaps.

To ensure the best performance and compatibility, it is recommended to consult with a Bama Tuning Experience Specialist when making any modifications to your vehicle, including fuel injectors. They will be able to provide specific guidance and ensure that your vehicle is properly tuned for safe and reliable horsepower.
