About
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.
CARPLAY READY
See your custom tachometer right on your car's display.
FEATURES

• Real-time tachometer with redline

EngineForge is for entertainment. Always keep your eyes on the road and follow
all local laws.
