Month 1: Overconfidence. I knew CAN bus but understood nothing about calibration. Opening a diesel binary in WinOLS was humbling.

Month 2-3: Building the combustion model. The torque model chapter-by-chapter built a mental model I didn’t expect.

Month 4: First file analysis. Bought a known-good Stage 1 and spent a week comparing against stock map by map. Not to copy — to understand the decisions.

Month 5: First real calibration attempt on my own car. Three iterations before I was satisfied.

Month 6: First paying client. Charged below market rate, documented everything, gave the client a log report.

The honest takeaway: The electrical background helped with diagnostics but didn’t shortcut the combustion physics. But it’s learnable. It’s not a dark forest when you have a methodology.

That methodology: Diesel Fundamental for the torque model, then Diesel Practice for real-file work.
