Turn your smartphone into a professional-grade engine analyser and performance dyno. Cylinder IQ Performance uses advanced GPS technology and artificial intelligence to deliver real-world horsepower, torque, and drivetrain data — no dyno, no OBD dongle, no expensive workshop equipment required.
Whether you're a weekend warrior, a seasoned racer, or a passionate gearhead, Cylinder IQ gives you the tools that used to cost thousands — right in your pocket.
REAL HORSEPOWER AND TORQUE Using high-precision GPS and your vehicle's weight, Cylinder IQ calculates real-world wheel horsepower and torque across every run. See your full power curve, find your peak RPM range, and understand exactly how your engine performs under load.
DRIVETRAIN LOSS CALCULATOR Go beyond wheel power. Cylinder IQ uses a physics-based three-component model to calculate your estimated crank horsepower — accounting for static parasitic losses, load-dependent gear mesh friction, and rotational inertia losses from your drivetrain components. See exactly where your power is going with a dynamic breakdown graph showing all three loss components simultaneously. No other mobile app does this at this level of detail.
AI-POWERED KNOCK DETECTION Cylinder IQ's acoustic AI listens to your engine through your phone's microphone and detects knock, ping, and detonation in real time. It doesn't just detect knock — it identifies which cylinder is knocking, giving you pinpoint diagnostic accuracy without specialist tools. Track knock events over time and get alerts before minor detonation becomes major engine damage.
AI MECHANIC — FULL ACOUSTIC DIAGNOSIS The AI Mechanic screen analyses your engine's full acoustic frequency spectrum to detect developing mechanical problems before they become expensive repairs. Detection includes water pump bearing noise, belt wear, exhaust leaks, valve train noise, general bearing wear, and engine misfire signatures. Every detected issue is assigned a severity level — Monitor, Investigate Soon, or Urgent — with a plain English description and recommended action. Diagnostic history is stored per vehicle so you can track whether a problem is getting worse over time.
ENGINE HEALTH SCORE Your engine receives a live health score based on knock frequency, severity, acoustic diagnostics, run consistency, and performance trends over time. Watch your score improve after a tune or catch a developing problem early. The Engine Health Score is your engine's report card — always honest, always up to date.
BLUETOOTH OBD-II SUPPORT Connect a Bluetooth OBD-II scanner for real-time coolant temperature, intake air temp, throttle position, fuel trims, and more. Combine OBD data with GPS performance metrics for the most complete picture of your vehicle's health and output.
RAW GNSS DATA LOGGING Log raw GNSS satellite data including accuracy, altitude, bearing, and speed across every run. Export your sessions for deeper analysis.
MY CAR GARAGE Store multiple vehicles with full drivetrain configuration, photos, and complete performance and diagnostic history. Every run and every AI Mechanic diagnosis is saved per vehicle automatically.
