About

APR PCU

Features
Read full description

The APR Power Control Unit (PCU) is an inline tuning box designed to increase the horsepower and torque of the vehicle! The plug-and-play control unit piggybacks off the primary Engine Control Unit (ECU) to deliver more boost, fuel, and timing to increase output. Using your smart phone or the optional wireless controller, you can change performance levels on the fly, revert to stock, adjust throttle sensitivity levels, read emissions readiness, read and clear fault codes, and more.

About

QC Lens

Read full description

QC Lens is a private, on-device workspace for inspecting watch quality-control photos. Import a complete photo set, correct camera perspective, inspect dial alignment with a precise 12-marker grid, record concerns, work through a practical checklist, and read timegrapher photos with on-device text recognition. Every OCR result remains a draft until you confirm or edit it. QC Lens preserves imported originals. Perspective, zoom, grid, and annotation data are stored separately, and photos are never uploaded by the app. Export an annotated dial image or an editable summary when you want another opinion. QC Lens assists visual inspection. It does not authenticate watches and never makes a GL/RL decision for you.
