Bench-Flash DEF Delete Tuning | Jeep Grand Cherokee 3.0L | 2014-2019

DEF delete tuning for Jeep Grand Cherokee 2014-2019

The 2014-2019 Jeep Grand Cherokee Bench-Flash Tuning service programs your original engine control module after you send it in. It is designed for the Grand Cherokee SUV with the 3.0L EcoDiesel engine.

The selected calibration changes EGR, DPF, and DEF/SCR control for the corresponding hardware configuration. Choose stock-rated power or an increase of up to 50 horsepower from the available stages. This tuning is designed for off-road and racing use.

Why Choose

• Professional programming - the removed ECM is flashed during the service.
• Three stage choices - Economy, Stock Plus, or Race.
• Original module retained - your existing ECM is returned after programming.
• No handheld purchase - no separate consumer programmer is needed.
• DIY guidance - instructions explain removal and reinstallation.

Vehicle Compatibility

Provide the VIN, modifications, and previous tuning details when ordering.

Components

• Bench-flash service - direct programming of your original ECM after receipt.
• Selected engine calibration - one Economy, Stock Plus, or Race tune matched to your vehicle.
• Removal and installation instructions - explain how to prepare, disconnect, and reinstall the module.
• Programmed original ECM - your existing module is returned with the selected calibration installed.
• Technical assistance - advice on preparation, installation, and troubleshooting.

The package includes programming of the supplied module, not a replacement ECM or handheld tuner. Exhaust parts and physical EGR removal hardware are separate purchases.

Tuning & Performance

Jeep Grand Cherokee tuning for DEF delete changes the engine software for a matching emissions-removal configuration. The calibration disables the relevant DEF dosing and monitoring requirements and changes DPF regeneration and EGR strategies.

Deleting software functions does not physically remove exhaust components. A retained DPF can accumulate soot when regeneration is disabled, so mechanical changes must follow the supplied instructions. Files are installed on the bench; this service does not provide remote OBD flashing.

Economy retains the stock output level with the selected delete calibration. It is not the original emissions-on file.

Matching calibration can unlock additional output and improve response; efficiency and actual power depend on vehicle condition, supporting parts, and driving. High power does not increase factory towing ratings. Only the chosen stage is installed; there is no switch-on-the-fly selection.

Installation

Instructions for Jeep Grand Cherokee EcoDiesel 3.0 DEF delete tuning are included. You need suitable hand tools, basic electrical and mechanical skills, and protective packaging. Disconnect the battery and remove the ECM according to the guide.

Resolve active faults, DPF/DEF countdowns, and existing SCR issues before proceeding. Previously tuned modules must be restored to the appropriate stock calibration before shipment. Use top-quality protective packaging to prevent connector and casing damage.

Send the module for programming, then reinstall it after return. Allow approximately 4-6 business days for processing after receipt, plus return transit. Removal, outbound shipping, and mechanical modifications add time. We provide remote advice; no calibration-writing experience is required.

Ordering Information

Select the best stage for your intended use and the correct year group. Most in-stock hardware orders are processed within 1-2 business days; this service also requires receipt and programming of your ECM. Carrier tracking provides shipment updates.

The selected file is installed on the module. A different stage requires reprogramming, not a customer-installed software update. Bench-flash services and custom files become final sale once processing or calibration begins. Eligible unused merchandise requires an RMA within 30 days of delivery. DEFDelete provides no separate store warranty; expressly stated manufacturer coverage applies to eligible products.
