Dealer update!

Make way for pure American muscle and heavy-duty workhorses! We are thrilled to announce that the Continental 5WY8 ECU, powering a wide range of Ford group vehicles from 2004 to 2015, is now officially supported on your AutoTuner Tool.

This protocol opens up massive tuning opportunities for American petrol powerplants. It fully covers performance icons like the Ford Mustang (including the fierce 5.4 V8 Supercharged and 6.2 SVT V8), as well as the kings of towing and hauling: the legendary Ford F-Series (F150, F250, F350, F450, F550) trucks driven by the massive 6.8L Modular V10 and V8 engines. Shared platforms like the Mazda CX-9 3.7 V6 and Lincoln MKZ are also included.

This is the ultimate solution to unlock horsepower, significantly increase low-end torque for heavy towing, or perform highly demanded Flex-Fuel (E85) conversions on these large-displacement engines!

⚡ Method: 100% OBD (Normal Read – NR) Pure workshop efficiency! No hardware removal or bench work is required. Simply plug your Tool directly into the vehicle’s diagnostic port to securely read and write the ECU with total confidence.

Supported Highlights (V6, V8 & V10 Engines):
Ford Mustang: 3.7L V6, 6.2 SVT V8, and the legendary 5.4 V8 Supercharged
Ford F-Series & Trucks: F150, F250, F350, F450, F550, E450 (5.0 V8, 6.2 V8 & 6.8L V10 configurations)
Ford SUVs & Sedans: Edge, Explorer, Taurus (3.5 V6 Duratec), Fusion US (2.5)
Lincoln & Mazda: Lincoln MKZ (3.7 V6), Mazda CX-9 (3.7 V6 MZI)

Dealer update:
Last February, we brought you support for Stellantis’ micro-mobility lineup via Boot mode. Today, we are making your workshop workflow even smoother: the EVPT VCU3000 Vehicle Control Unit is now officially supported via Bench mode on your AutoTuner Tool!

These highly popular 5.5 kWh urban electric cruisers—the Citroën AMI, Fiat Topolino, and Opel Rocks-e—are a massive hit on the streets, and the demand for software optimization is growing fast. This update is your perfect gateway to handling these vehicles efficiently.

⚡ What’s new: 100% Bench (Normal Read – NR)
No more opening the VCU cover! You can completely skip Boot mode now. Simply connect your Tool directly to the VCU3000 external pins to securely read and write calibrations on your workbench, saving you precious time.

Supported Highlights (5.5 kWh Electric Powertrain):
Citroën AMI (2020+)
Fiat Topolino (2023+)
Opel Rocks-e (2021+)
