35whp gain at redline from restriction removal
You can use it with factory or aftermarket exhaust!
Fan Early Option:
All our Ducati V4 flashes include early fan activation for improved cooling efficiency.
In every file, the fan is calibrated to start at 185°F (85°C) to help keep engine temperatures under control during everyday riding and stop-and-go traffic.
For 2025 Ducati V4 models, please note that the fan system may be managed by two separate controllers the ECU and the BBS module.
In these cases:
You may notice the fan staying on for a short period after shutdown this is normal and indicates that the ECU control is working as intended.
If the fan does not engage while the engine is on, your specific bike likely handles that function entirely through the BBS module, which cannot currently be modified.
