From the garage
Product updates, tuning workflow ideas, and practical EFI notes — written by the Crazy Tuner team.
Start with the product overview, how it works, or pricing. DIY builders and shops & tuners explain who Crazy Tuner is for; FAQs cover credits, plans, and privacy.
Articles here focus on practical EFI topics: reading logs for specific failure modes, how AI-assisted summaries fit into a safe tuning process, and product updates as we expand ECU coverage and shop workflows. Each post is written for people who already work with standalone or laptop-tuned systems and want sharper diagnostics without replacing human judgment on the car.
Expect write-ups on lambda trends under boost, transient fueling around tip-in and shifts, ignition timing and knock behavior, fuel pressure and injector duty anomalies, and boost control strategies that show up differently on Holley, MoTeC, Haltech, FuelTech, and HP Tuners exports. When we ship parser improvements or new workspace features, we explain what changed and how it affects your upload workflow so you are not guessing from a changelog alone.
If you are comparing Crazy Tuner to doing everything by hand in a spreadsheet, the theme is the same: structured narrative, confidence, and a short checklist beat scrolling thousands of rows cold. The blog is where we spell out that philosophy with examples, while the app is where you run analyses on your own CSV pulls.

Posts here complement the in-app experience: they explain how we think about safe AI-assisted diagnostics, what a good log pull looks like before upload, and how shops can slot structured reports next to dyno sheets and customer notes. We avoid hype about “self-tuning” ECUs—the product is a copilot that still expects you to verify on the car and in your calibration software.

Reading list vs. in-app analysis
Blog posts are editorial: they help you think about methodology, safety, and when to escalate to a human calibrator. The product, by contrast, ingests your actual log file and returns a report tied to the vehicle profile you saved—so the two together reinforce each other rather than duplicating the same content.
