EFILive V3 Delete Kits & Tuning Options

EFILive V3 Delete Kits — Quick View

This is SPELAB's EFILive collection: delete kits and tuning packages built around the EFILive AutoCal V3 platform, plus the OBDII flash tuning packages used on the newest engine platforms. If you are shopping by device rather than by truck, this is the page to start on — every kit here is grouped by which tuner option it ships with, so you can pick the EFILive device and tune style first, then confirm fitment on the product page. In addition to our featured EFILive V3 kits, this collection also includes select V2, V1, and other tuning options. Click on any product to view its available tuner options. If you have any questions, feel free to contact our customer support team.

One thing to know before you order: an EFILive AutoCal ships as hardware and software only, without tune files loaded. Custom tunes are written by a tuning provider for your specific VIN and modifications, delivered as a quick setup file, and loaded onto the device from a Windows PC. SPELAB supports the complete ordering and setup path, so contact us before or after the purchase if anything is unclear.

What Is EFILive?

EFILive is a diesel tuning and diagnostics software ecosystem built around two things: the EFILive software suite that runs on a Windows PC, and the handheld AutoCal device that connects to the truck. The software reads and writes the engine controller's calibration; the AutoCal stores those files and delivers them to the truck through the OBDII port.

EFILive supplies the tooling, not the tune. That distinction matters: the AutoCal device arrives without calibrations, and the actual tune files are written by a tuning provider for your specific VIN, engine and current modifications. EFILive is also written as EFI Live or efilive — all three spellings refer to the same platform.

What Is the EFILive AutoCal V3?

The AutoCal V3 is the current-generation EFILive handheld device. It stores calibrations, log files and device configuration, then flashes them to the engine controller through the OBDII port. Compared with earlier hardware, the V3 adds 512MB of internal storage for hundreds of tune and log files, file transfers up to 10 times faster, support for up to 600 VIN licenses, built-in USB drivers so it appears as a standard Windows USB drive without a driver install, and a backup power supply that protects data if power drops during a flash.

In practical terms, the AutoCal V3 is what makes custom EFILive tuning usable on the truck: you load the file your tuning provider sends onto the device from a Windows PC, plug the device into the OBDII port, and program the controller.

Which EFILive Kit Fits Your Truck?

Kits in this collection are organised by engine platform, because the tuner option and the ECM requirements change from one platform to the next. Start by identifying your engine platform, then open the matching product page — that is where exact model years, cab configurations and fitment exclusions are listed.

Note for the newest model years: the current-generation ECM is tuned through the OBDII flash interface rather than the AutoCal device, and it requires an unlock service that is not included in the kit. Contact SPELAB before ordering so we can confirm the exact process for your year group.

If your truck sits on a platform not listed above, this collection does not cover it — browse the shop for the matching all-in-one kit instead, or send us your engine code and model year and we will point you to the right product.

EFILive Tuner Options Explained: V2, V3, V3 with SOTF, or Without Tuner

The all-in-one kit is configured with four tuner options. The V3 options run on the EFILive AutoCal V3 platform; the V2 option is an alternative handheld delete tuner with preloaded delete tunes and a built-in monitor display.

Prices are the lowest configuration for each option and vary with the EGR and CCV selections on the same product. If you are not sure which option matches your goals, contact SPELAB before ordering.

Which tuning path do you want — preloaded handheld or custom EFILive tuning?

The V2 and V3 options are not two generations of the same device — they are two different ways to tune:

• The V2 option is a self-contained handheld tuner: delete tunes come preloaded, settings are selected on the device, and the unit doubles as a full-time gauge monitor. It is the simpler path if you want a plug-and-play solution without a PC in the loop.
• The V3 options (EFILive AutoCal V3) are a custom-tuning platform: tune files are built by a tuning provider for your specific VIN and modifications and loaded from a Windows PC. Alongside the hardware upgrades listed above, V3 with SOTF adds a Shift-on-the-Fly tune, so supported power levels can be switched from an in-cab rotary switch while driving.

In short: pick V2 if you want preloaded tunes and a built-in monitor with no computer needed; pick V3 or V3 with SOTF if you want a custom EFILive tune tailored to your exact truck and modifications.

What's Included — and Where Your EFILive Tune File Comes From

What comes with the tuning side depends on which kit you buy:

• All-in-one kit with EFILive tuner options: selecting V2, V3, or V3 with SOTF includes the tuner device with a calibration; your tune provider emails the *.bbx quick setup file for loading from a Windows PC. The Without Tuner option is delete hardware only.
• OBDII flash all-in-one kit: the OBDII Flash Delete Tuning Interface is available as an option, but credits and the tune file are not included — the option is listed as "OBDII Tuner (won't include file)". Tune files and credits are sold separately through the in-store tuning package, which covers the OBDII interface, unlock kit, SOTF tune file, and 4 or 8 credits in the combinations your year group needs.
• All-in-one kit with selectable exhaust: the tuning package is included — OBDII interface, tune file, and credits for your year group (the ECM unlock kit is included on the earlier year group).

Here is the full chain, so there are no surprises: EFILive supplies the hardware and software only. Custom tune files are written by a tuning provider for your specific VIN and modifications. After your order, you submit your vehicle details (engine, model year, transmission, current modifications), the file is built for your truck, and it is delivered as a *.bbx quick setup file that you load onto the device from a Windows PC. On supported platforms the SOTF tune is switched from the factory steering wheel controls. Support for the device and the file is handled by SPELAB — contact us at any step in the chain. All tunes are non-refundable once purchased, so verify compatibility before completing the order.

ECM Unlock & Credits — What to Check Before Ordering

Before a controller can be flashed, some model years need an ECM unlock, and every flash consumes ECM credits. What your truck needs depends on the year group, so confirm it before ordering.

The 5-level Shift-on-the-Fly tune offers selectable power levels of 0 / 50 / 75 / 100 / 150 HP on supported trucks, switched from the factory steering wheel controls — we strongly recommend monitoring EGTs on the two highest levels. One fitment note: the delete hardware in this collection is listed as not compatible with cab & chassis models, while the tuning side supports certain cab & chassis trucks with a 60 HP tune limit. If you drive a cab & chassis truck, contact SPELAB before ordering so we can confirm the right path.

Whenever an ECM unlock is performed, make sure the truck's batteries are fully charged and the voltage stays stable — a low battery can cause the unlock to fail and leave the ECM in a recovery state.

What Results to Expect — and Where the Limits Are

For off-road applications, a typical delete kit with a custom tune on a stock fuel system and stock turbo supports roughly 50-80 additional horsepower and 100-150 lb-ft at the wheels, along with a 2-5 MPG improvement from eliminating active regeneration cycles, cooler EGTs under load, and faster turbo response. Actual results depend on the tune level, your supporting modifications, and your transmission.

Two limits worth knowing before you order: first, these kits tune the engine calibration only — transmission (TCM) programming is not included, and on higher power levels the transmission becomes the limiting factor before the engine does. Second, the fuel system and turbo also reach their limits before the engine does, so a conservative tune on a stock truck is the reliable setup. If your goals go beyond that, talk to SPELAB about what supporting modifications should come first.

Installing & Loading Your EFILive Tune

Loading a tune onto an EFILive AutoCal device is done from a Windows PC with the EFILive software — no dealership visit required. Prepare the truck first, update the device, then program the quick setup file your tune provider sends you.

1. Connect a quality battery charger. Maintain stable voltage for the whole session — low voltage during a flash can corrupt the process and damage the ECM.
2. Update the firmware first. Open EFILive V8 Scan and Tune on a Windows 10+ PC, select Check for Updates, then Check Firmware, and update both the firmware version and the configuration files. Skipping this step may cause compatibility issues and can damage the ECM.
3. Back up your stock calibration. Save a copy of the factory file before your first custom flash — you will need it for warranty work or resale.
4. Confirm the file is for your truck. Check that the digits in the tune file name match the last digits of your VIN before programming. A file built for a different truck must never be flashed.
5. Get your quick setup file. Your tune provider emails a *.bbx quick setup file that contains the device settings, controller configuration and tune files. Save it to \Documents\EFILive\V8\BBX (a Downloads or Desktop folder also works).
6. Connect the device. Connect the AutoCal to your PC with the USB cable and open V8 Scan and Tune. Keep the ignition ON without starting the engine, and do not power your laptop from a DC-to-AC inverter while connected to the vehicle.
7. Program the quick setup. Navigate to [F5: BBX] then [F6: Quick Setup], select Open Quick Setup, choose the *.bbx file your tuner sent, and select Program Quick Setup. Do not modify any settings your tune provider defined unless they ask you to. Keep the radio off and avoid opening doors or moving windows during the flashing process.

If you see an error code while programming: stop — do not retry blindly. EFILive publishes a full error code list for the AutoCal and V8 Scan and Tune; check your code there first, then contact SPELAB support with the code, your device serial number, and the step you were on.

V3 with SOTF buyers: the rotary switch that selects your power level mounts in the cab and needs to be wired during installation — follow the SOTF switch install guide on the product page so you can tell tune levels apart from day one.

For the hardware side, follow the platform-specific guides listed on each product page — AutoCal vehicle install instructions, SOTF switch installation, and bypass cable installation for supported off-road applications. To keep the device healthy, keep it out of direct sunlight (heat damages the display and keypad), avoid rapid repeated plugging of the USB connector, and eject it safely before unplugging when it is used as a USB drive.

Off-Road Use Only

Some products and tuning options in this collection are intended for off-road, racing, competition, or closed-course applications only. They are not intended for use on registered street vehicles where emissions equipment is required. Removing emissions components may violate emissions regulations — customers are responsible for checking and following all applicable local, state and federal laws before purchase, installation or use.

Need Help Choosing Your EFILive Setup?

Confirm three things before ordering: your engine platform, whether you want the EFILive tuner included, and which emissions components you plan to delete. Each product page lists the exact model years and configurations a kit covers — if your truck is a cab & chassis model, or you are unsure which ECM unlock applies to your year group, contact SPELAB and we will confirm the correct configuration before you buy.

Prefer a no-computer workflow? The EFILive path requires a Windows PC for firmware and tune files. If you would rather load tunes from a phone app with cloud delivery, see our cloud-connected tune packages — the alternative in the same shop.
