Wrumer vs EngineForge

Wrumer connects* to your car's internal computer and its speakers. It reads the car's RPM speed and throttle application and based on that plays an enhanced engine sound through your car's speakers. You can choose between multiple car engine sounds and effects, such as a Turbo Whistle and Backfires. *For the app to connect you also need the Wrumer device. You can get the Wrumer device at https://wrumersound.com.

EngineForge turns your iPhone into a live engine sound simulator. Pick an engine — inline-four, V8, flat-six and more — and EngineForge generates a real-time tachometer and exhaust note that responds to how you actually drive. NO ADAPTER REQUIRED EngineForge reads your speed and acceleration straight from your iPhone's GPS and motion sensors, revving the simulated engine as you accelerate and settling as you cruise. WANT REAL DATA? Connect a Bluetooth OBD2 (ELM327) adapter to drive the revs from your car's actual throttle position. Electric vehicle mode reads speed instead of throttle.
