Automotive Field Theory

Thanks to our Partner, NAPA Autotech Training

In this technical deep-dive, Matt Fanslow tackles the misconceptions surrounding Exhaust Gas Recirculation (EGR) in modern engines. Far from just a NOx-reduction tool, EGR plays a critical role in thermal efficiency, throttling losses, and combustion control. Matt dismantles common myths (like "lean burns hotter") and explains why engineers use EGR—even as technology evolves.

Key Topics Covered

EGR’s Real Purpose

• Beyond NOx reduction: How inert exhaust gases slow flame fronts, improve thermal efficiency, and reduce throttling losses.
• Why lean air/fuel ratios don’t burn hotter—but can still cook exhaust valves.

Throttling Losses & Efficiency

• How EGR allows wider throttle openings, reducing engine workload and boosting fuel economy.
• The link between EGR, Atkinson/Miller cycles, and extended combustion push.

Internal EGR & Valve Timing

• Modern engines use cam phasing to trap exhaust gases, creating insulating "pockets" that reduce heat loss to cylinder walls.
• SAE paper highlights: HCCI engines, controlled auto-ignition, and residual gas effects.

Why This Matters for Technicians

• Understanding EGR helps diagnose drivability issues, software updates, and emission failures.
• Matt’s rabbit-hole warning: Complexity is growing, but so are diagnostic opportunities.

Notable Quotes

• "Lean air/fuel ratios burn longer, not hotter—that’s why exhaust valves fry."
• "EGR isn’t just about emissions; it’s about making the engine work smarter, not harder."
• "The more you know why engineers do something, the better you’ll diagnose it."

Resources & References

• SAE Papers (Available at sae.org):
• Lean Burn SI Engines: NOx Control via Air/Fuel Ratio Modulation (2017)
• Impact of Valve Timing on Cold Start Emissions in GDI Engines (2019)
• Effects of Valve Timing on Residual Gas, Combustion, and Heat Transfer (2009)

Introduction & Personal Anecdote

• Explains his motivation for visiting a quick lube shop: to observe different shop practices and customer experiences.

The Quick Lube Experience

• Initial Interaction: Shop employee questions the high mileage (300,000) on Matt’s Honda and suggests a possible engine replacement.
• Upsell attempts begin immediately, including high-mileage oil with unverified fuel economy benefits.
• Air Filter Upsell: Employee claims a dirty air filter significantly impacts fuel economy—Matt debunks this myth, citing modern mass airflow sensor engines.
• Notes that restricted air filters may improve fuel economy or have no effect.
• Cabin Air Filter Incident: Employee misgenders Matt’s son (who has long hair) while accessing the glove box.
• Matt critiques the approach, suggesting gender-neutral language when interacting with customers.
• Coolant Flush Upsell: Employee claims the coolant should be flushed annually (without evidence) and criticizes another shop’s pricing.
• Matt finds this tactic dishonest and unprofessional, especially without knowing the specifics of the previous service.

Industry Critiques & Observations

• Upselling Tactics: Questions whether misleading claims (e.g., air filters hurting fuel economy) stem from lack of training or corporate policy.
• Criticizes the focus on commission over honesty.
• Bashing Competitors: Disapproves of shops disparaging others based solely on price without understanding service details.
• Argues this erodes customer trust and harms the industry long-term.
• Customer Interaction: Highlights the importance of transparency and avoiding gender assumptions.
• Reflects on whether exaggerated "skill level" claims (e.g., "this was really hard to do") build customer confidence or backfire.

Listener Engagement

• Asks listeners to share their experiences:
• Have you visited other shops as a "regular customer"? What did you observe?
• Do you reveal your industry background, or play along to see how you’re treated?
• How do you handle unethical practices when you encounter them?

Closing Thoughts

• Reiterates refusal to badmouth competitors or compete on price alone.
• Advocates for integrity, proper training, and focusing on quality repairs.

Key Takeaways:

Survey Demographics & Limitations

• Skewed Representation: 62% of respondents had 20+ years of experience, while entry-level and mid-career techs were underrepresented. Geographically, responses were heavy in the East/Midwest but sparse in central/western U.S.
• ASE Certification Bias: 80% of respondents held ASE certifications, contrasting with the broader industry (only ~25% of U.S. technicians are ASE-certified). Fanslow urges broader participation for accurate data.

What Technicians Want

• Proper shop equipment (87%) – Includes OE tools (e.g., GTS+ for Toyota/Honda), ADAS calibration tools, and powertrain tables 210.
• Paid vacation (83%) and retirement plans (72%) – Fanslow notes ambiguity in definitions (e.g., weeks offered) and calls for industry standardization.
• Paid training (65%) – Despite high demand, many techs underutilize training opportunities.
• Hourly/salary (majority) > hourly + production bonus (25%) > flat rate (20%). Fanslow attributes this to desire for stability, especially in rust-prone regions where labor guides may be unrealistic.

Industry Pain Points

• Low Satisfaction: Only 49% would recommend their shop to a friend. Poor communication (30% approval) and inadequate mentorship (<30%) are key issues.
• Urgent Needs: Higher pay (78%) – Fanslow advocates for cost-of-living-adjusted wages over raw dollar comparisons.
• Better benefits, tool allowances, and management (13–14%) – Vague but critical for retention.

Call to Action

• Increase Survey Participation: Fanslow urges technicians to join WrenchWay (free) to amplify diverse voices, especially from underrepresented regions/experience levels.
• Shop Owner Accountability: Recommends transparent conversations about compensation, equipment, and mentorship programs to address dissatisfaction.

Notable Quotes

• “4700 respondents is impressive, but in a field of 800,000 technicians, it’s hardly a scratch.” – Matt Fanslow
• “If you’re not paying attention to cost-of-living-adjusted wages, you’re missing the point.” – Matt Fanslow

Actionable Insights

• For Technicians: Join WrenchWay to contribute to future surveys. Advocate for clear career paths and training at your shop.
• For Shop Owners: Benchmark pay against local cost of living. Invest in OE tools and mentorship programs to retain talent.
• Industry-Wide: Address communication gaps and collaborate with schools to improve perceptions of the trade (only 25% of shops support local schools).

Ubuntu – What It Means

• Ubuntu is an African philosophy that translates to "I am because we are."
• It emphasizes collective success: "I succeed because you succeed."
• Matt discovered the concept through a documentary on the Boston Celtics.

Lessons from the Boston Celtics

• The Celtics’ success was built on teamwork, sacrifice, and shared goals.
• The "Big Three" (Paul Pierce, Kevin Garnett, Ray Allen) were asked by Coach Doc Rivers: "What are you willing to give up to win?"
• Unlike professional athletes, most employees don’t have financial security, making true teamwork harder to achieve.

Applying Ubuntu in the Auto Repair Industry

• Success in a shop depends on collaboration, not just individual performance.
• Leaders must foster a culture where employees support each other’s growth.
• Challenges:
• Money can distort priorities—owners and employees must trust that success will be shared.
• Transparency is key—profits should lead to better pay, equipment, and shop improvements.

The Risk of Greed & Lack of Accountability

• Some owners struggle to share profits even when business improves.
• Employees may also lose integrity if incentives aren’t aligned with teamwork.
• Solution: Clear structures (bonuses, profit-sharing) that reward collective effort.

Building a Winning Shop Culture

• Invest in team development—better tools, training, and processes.
• Encourage knowledge-sharing instead of hoarding skills.
• Success isn’t zero-sum—multiple shops can thrive without undercutting each other.

For Owners/Managers:

• Back up "team-first" talk with real profit-sharing and shop improvements.
• Show employees how their sacrifices lead to shared rewards.

For Technicians/Advisors:

• Support colleagues—helping others succeed lifts the whole shop.
• Push for transparency if incentives feel unbalanced.

For Everyone:

• Watch sports documentaries (like the Celtics’ story) for leadership lessons.
• Adopt Ubuntu: "I am better because we are better."

In this episode, Matt Fanslow dives into listener-submitted questions, covering a wide range of automotive diagnostic and repair topics. From personal influences in the industry to technical advice on exhaust gas analyzers, catalytic converter testing, and ADAS calibrations, Matt shares his insights and expertise.

Matt reflects on the mentors and industry leaders who have shaped his approach to diagnostics and repair.

• TV Doctors vs. Real Mentors: While he jokes about emulating fictional doctors like Hawkeye Pierce, Gregory House, and Perry Cox, Matt credits real-world experts like John Thornton, Randy Burkholder, Jim Kemper, Matthew Ragsdale, Harvey Chan, and John Riegel for their influence.
• The Value of Deep Research: Matt highlights the importance of studying SAE documents, technical manuals, and foundational books like Internal Combustion Engine Fundamentals by John B. Heywood.
• Thought Leaders in the Industry: He also mentions Jim Wilson (ScanShare.io), Scott Manna, and others for their diagnostic methodologies and problem-solving approaches.

Takeaway: Success in automotive diagnostics comes from continuous learning, leveraging industry resources, and adopting best practices from experienced professionals.

A listener asks about choosing the right exhaust gas analyzer for their shop. Matt breaks down the key features:

• PC/Android Interface: Essential for graphing gas readings (lambda, air-fuel ratio) over time.
• Portability: Needed for on-road testing to monitor performance under real driving conditions.
• Fast Sample Times: Look for analyzers with low transfer delays (under 5 seconds) for accurate real-time data.
• Cost Consideration: Expect to invest 
• 5,000–
• 5,000–7,000+ for a quality unit.

 Takeaway: A good exhaust gas analyzer should provide real-time data logging, lambda calculations, and portability for effective diagnostics.

A student questions the validity of using infrared thermometers to test catalytic converters after hearing conflicting advice.

• PCM Algorithms Are Superior: Modern vehicles use complex oxygen storage calculations—far more accurate than manual temperature checks.
• Why Temperature Testing Falls Short:
• A "bad" cat might still pass a temp test.
• A "good" cat might fail due to external factors (exhaust leaks, sensor issues).
• Best Practice: Trust OBD-II diagnostics, fuel control verification, and factory procedures over manual methods.

Takeaway: Always verify fuel control, exhaust integrity, and PCM data before condemning a catalytic converter.

A technician struggles with static calibrations for windshield-mounted cameras. Matt offers troubleshooting tips:

• Check the Windshield Glass: Aftermarket glass is a common culprit for calibration failures.
• Lighting Conditions:
• Too much LED glare? Try diffusers or dimming shop lights.
• Use shipping blankets to reduce reflections on the hood/dash.
• Target Placement: Ensure the target is positioned per OEM specs—avoid background interference.
• RTFM (Read the Factory Manual): Always follow OEM procedures for target setup.

Takeaway: Calibration issues often stem from glass quality, lighting, or incorrect target alignment—double-check these factors first.

Key Discussion Points:

What is Reverse Benchmarking?

• Traditional benchmarking focuses on studying what competitors do well, but reverse benchmarking involves analyzing what they do poorly and capitalizing on those weaknesses.
• Two interpretations:
• Looking at other industries for innovative ideas (e.g., team-building activities from tech companies).
• Example: Some shops now adopt spontaneous team outings (baseball games, go-karting) inspired by Silicon Valley culture.
• Staying within the automotive industry to identify gaps in competitors' customer experience or service offerings.

Applying Reverse Benchmarking in Auto Repair

• Customer Experience:
• Visit competitor shops (dealerships, independents) and note flaws—uncomfortable waiting room chairs, poor TV choices, limited snack/drink options.
• Actionable Fixes: Upgrade seating, offer neutral TV content (e.g., Joy of Painting), provide filtered water instead of plastic bottles.
• Market Gaps:
• If competitors specialize in European cars (like Seth Thorson’s shop), consider specializing in underserved markets (e.g., Asian brands like Hyundai, Kia, Nissan).
• Focus on services competitors avoid (advanced diagnostics, programming, driveline work).

Technician-Level Reverse Benchmarking

• In a shop with a star "R&R tech," instead of competing directly, fill gaps (e.g., diagnostics, electrical troubleshooting) to become indispensable.
• "See a need, fill a need"—position yourself as the go-to for overlooked but critical tasks.

Why It Works

• Creates a unique value proposition—whether for customers (better experience) or employers (specialized skills).
• Helps shops stand out in saturated markets by addressing unmet needs.

Final Thoughts:

• Reverse benchmarking isn’t new, but it’s underutilized in automotive.
• Whether you’re a shop owner, manager, or tech, observing competitors’ weaknesses can reveal opportunities for growth.

The Problem:

• A 2023 Jeep Grand Cherokee (collision repair) came in with blind spot warning and parking aid malfunction lights on.
• No functionality in either system post-repair.

Initial Diagnosis:

• Verified the concern (instrument cluster lit up with warnings).
• Used an aftermarket scan tool (Snap-on Ultra) and found:
• ADAS control module had multiple DTCs for open/short circuits on all radar sensors.
• Parking aid module had similar codes for ultrasonic sensors.
• Vehicle was hit in the passenger rear, leading to replacement of the bumper, harness, and rear hatch.

Suspected Causes:

• Blown fuse (common culprit for multiple system failures).
• Crushed/damaged wiring harness (common after collisions).
• Module failure due to impact.

Testing & Findings:

• Checked power and ground at the ADAS module—all good.
• Inspected wiring harness for damage (no visible issues).
• Critical Clue: Wire colors didn’t match the schematic.
• Initially dismissed as a common schematic error.
• Later realized the entire harness was installed backward (left/right sides flipped).

The Fix:

• Flipped the harness and radar modules to their correct positions.
• All codes cleared except two for the blind spot radars—turned out they were also swapped.
• After correction, all systems worked perfectly.

Lessons Learned:

• Don’t get stuck in a diagnostic rabbit hole. Good techs pivot when clues don’t add up.
• Man-made problems can be the trickiest. Always verify previous work (especially after collisions).
• Wire color discrepancies matter. Even if schematics are often wrong, they can reveal bigger issues.
• "Slow down to speed up." Rushing leads to wasted time; methodical checks save hours.

Final Thoughts:

• Awareness is key. Catch yourself when fixating on one theory.
• Experience can work against you. Stay open to new clues, even if they conflict with past patterns.
