Today we’re rebuilding the rear brake calipers on a DeLorean — a job that solves common issues such as dragging brakes, uneven pad wear, sticking pistons, and handbrake imbalance. The DeLorean’s rear calipers have some unique design quirks, including the integrated...
Learn practical lab-scope workflows you can use today. We reinforce the basics with real-world tests: checking primary ignition current with a low-amp probe, verifying an entire bank of coils via the common power feed, reading fuel-pump current through a fuse-loop...
Everyone’s talking about how bad the automotive industry is right now — low pay, burnout, lack of respect, and technicians leaving the trade. But that’s only half the story. In this video, I talk about what’s really going on in the automotive world — and why it’s not...
Automotive Lab Scope Basics | Understanding the uScope In this video, we walk through the fundamentals of using a lab scope (automotive oscilloscope) — what it does, how it works, and why it’s one of the most powerful diagnostic tools you can own. Using a signal...

Diagnosing with Fuel Trim | O2 Data, Pulse Width, and Real Scan Tool Tips
Learn how to diagnose engine performance issues using short and long term fuel trim data. This hands-on scan tool demo shows live readings from a 2009 Subaru Outback and explains how the ECU responds to rich and lean conditions.
Full Description
In this video, we connect a scan tool to a 2009 Subaru Outback and walk through how to use generic OBD-II data instead of vehicle-specific parameters to diagnose engine performance. Learn how to:
🔹 Customize PID lists to show only the data you want
🔹 Read and understand short-term and long-term fuel trim
🔹 Monitor oxygen sensor data in real time
🔹 Identify rich and lean conditions using live engine response
🔹 Understand pulse width modulation and injector control
🔹 Diagnose drivability problems using fuel trim patterns
We also demonstrate how the system compensates for induced fuel mixture issues and discuss what normal vs abnormal data looks like. Whether you’re a DIY enthusiast or a pro tech, this video is packed with practical info.
