In-Cylinder Pressure — PDS500x

What it tells you

With the PDS500x transducer in the cylinder, the pressure trace draws the engine's mechanical story — compression peaks, valve events, and exhaust restriction. The 100µS response catches defects a static compression test will always miss.

Symptoms this catches

• ▸low power
• ▸compression
• ▸valve timing
• ▸exhaust restriction
• ▸cam
