It is safe to call EFI Live one of the most potent tunning devices ever. Diesel and fuel-using machines make use of EFI Live, especially trucks. It is a tool that permits the user to electronically adjust the stock ECU and TCM data in a vehicle. The EFI Live helps increase a vehicle’s performance and, most times, go with a lift pump for max performance.
The question “do you need a lift pump for EFI Live” is that of LML capacity. While some truck models have high-pressure CP3 fuel pumps, others might not and will need a lift pump to aid the vehicle if tuned. Keep reading. This article explains everything about EFI Live and the lift pump.
Do You Need A Lift Pump For EFI Live?
A lift pump is necessary while using EFI Live, especially if the truck does not have an inbuilt high-pressure pump. A lift pump increases the rate of performance and filtration and reduces the stress going to the CP4. It increases the reliability rate and performance of your truck.
This question is mainly one people ask once they do not see an option for tunning a lift pump. A lift pump does not affect an EFI Live. It only reduces the stress on the CP3 and increases the filtration rate in the factory pump.
Tunning a truck without a high-pressure pump will need a lift pump for better reliability and performance. So, yes, you need a lift pump for EFI Live. If you increase the performance of a truck, then you should help the car relieve the stress that comes with the increase.
It is best to get a lift pump that fits your vehicle’s engine capability. If the pump capacity is higher than required, there is a risk of having tank problems. The option to use a lift pump for EFI Live is one the mechanic gives for you to be on the safe side.
What Do I Need To Tune With EFI Live?
EFI Live serves many functions, from monitoring your car engine to making specific changes to the car’s drivability. They are a range of things you need to tune with EFI Live. However, these things are at your discretion. It is not a must to adjust all tuneable features. The features you need to tune with EFI Live include:
- Turbocharge boosting.
- Low-end smoke tuning.
- Speed-limit limitation.
- Rail pressure regulation.
- Timing rattle maximization.
- Transmission change strategy.
- EGT boosting.
The beauty of tunning a vehicle is its data-logging capability and the straightforward nature of flipping a tune to another. There is no waiting time between tunes. You can have up to five different tune set-ups and easily switch around.
Do I Really Need A Lift Pump On My Duramax?
Duramax factory pumps have some shortcomings. Although the deficiencies are not very damaging, it is excellent to take measures to ensure those shortcomings do not affect your vehicle heavily. While some Duramax models have CP3 high-pressure pumps, they will need extra support from a lift pump.
It would be best to add a lift pump to give additional filtration capacity and reduce the pressure of drawing fuel on the CP3. Duramax vehicles are susceptible to contaminated fuel. Sometimes the CP3 pump filter might not be able to filter all debris. This point is where the lift pump comes in.
Installing a lift pump between the CP3 and the tank takes the bulk of the stress on the pump. It also helps the pump filtration part to work better. In general, the lift pump is necessary for reliability and performance needs. Ensure you get fuel from a good gas station to avoid contaminated fuel.
How Do You Hook Up A Fuel Pump To An Efi Live?
In the past, hooking up a fuel pump to an EFI Live was a daunting task involving wiring and tunning complications. But now, they are effortless ways to hook up a fuel pump to an EFI Live that doesn’t need plenty of Tunning knowledge. These methods include the installation of ready-made EFI Live matching fuel systems like:
1. EFI Fuel Tank Modules
These tank modules go into the factory tank to replace the fuel sender. The EFI fuel tank module has a high-pressure pump, pressure regulator, and fuel reservoir and works with the hard lines and gauges in the factory tank to provide the tuning effects.
The EFI tank modules are the easiest way to hook up a fuel pump to an EFI Live. It cuts off the need to buy fitting and cables. It also removes the option for routing and return line running. It is simple installation-wise and maybe the best way to hook up.
2. Baffled EFI Conversion Fuel Tank
This method is vital if the fuel tank is old and rusty. The EFI conversion fuel tank comes with a fuel pump inside the tank. And it does not need any fabrication for installation.
Using an EFI conversion tank helps prevent debris blocking the fuel filter from rust in the old tank. While you can buy a new factory tank and use the EFI fuel tank modules, getting the conversion tank and having both level sensors, tank, and pump at once is better.
3. Retrofit In-tank Fuel Modules
Retrofit in-tank modules are for vehicles whose factory fuel tank doesn’t have a muscle car module. Installation is via a hole cut atop the tank. Swing cams catch the tank material and insert a neoprene gasket.
Retrofit in-tank modules have backward and forward pump features and AN return, vent ports, and outlets on their top. These modules can support up to 1200 Efi-added horsepower.
4. In-line External Pumps
In-line external pumps are perfect for race cars. They quickly change when a fault develops, especially during a race. Although the in-line external pump does not have cooling effects, it has redundancy. Its redundancy effect means the vehicle will not face a DNF while driving.
The driver can easily change from the in-line pump to the primary pump. The disadvantage to this application is its tendency to get hot and loud due to poor liquid insulation. But it is cheap and easy to install.
5. EFI Fuel Cell Pump
The fuel cell pump attaches to the fuel cell caps. They are easy to install and have AN ports. They are available in single or dual-unit pumps. EFI fuel cell pumps can carry up to 1,100 horsepower carburation.
Hooking up an EFI system to your fuel system gives your additional vehicle power, fuel economy, electronic fuel injection, and drivability. The best part is the ability to install it in any vehicle type with ease.
EFI Live gives a car owner flexibility and customization ability to the vehicle. It does not just help increase or reduce the vehicle features. It has excellent diagnostic capacity. EFI Live pairs with a lift pump to give the vehicle higher reliability so the car will not buckle under the added power from tunning.
If you own a muscle or race vehicle, the use of EFI Live will expose the workings of your car engine and allow you control to personalize your truck. This article has dealt extensively with the question, “do you need a lift pump for EFI live.” So now, you know the advantages of getting one.
