How to Find the 370Z Hidden Timing Window for 25HP Gains

370Z owners are discovering a timing advance window between 2500-4500 RPM where the factory ECU pulls back too conservatively. Adding 2-3 degrees here safely unlocks 25 hidden horsepower most tuners miss completely.

Why Spring Temperature Changes Wreck STI Tunes (Data Analysis)

Temperature swings of just 20°C can shift your STI's knock threshold by 2-3 timing degrees, turning a safe winter tune into engine damage. Here's what your datalogs are actually telling you about seasonal temperature changes.

Why WRX Knock Sensors Go Crazy on E85 (It’s Not Octane)

Your WRX's knock sensor lighting up on E85 despite ethanol's 105 octane rating? The problem isn't octane, it's tuning. E85 requires completely different AFR targets and timing maps than pump gas.

E85 Timing for 370Z: The Sweet Spot Most Owners Get Wrong

Most 370Z owners running E85 are leaving 15-20 wheel horsepower on the table with overly conservative timing advance. Our analysis of 50+ dyno runs shows the real sweet spot is higher than you think.

Why Stock Boost Controllers Leave 40+ HP Hidden in Your Type R

Stock boost controllers hit 22 PSI perfectly but leave 40+ horsepower on the table through conservative ignition timing maps. Recent dyno comparisons between Civic Type R and Golf R reveal the real bottleneck isn't hardware.

Does Higher Timing Advance Always Mean More Power? What the Data Shows

Most tuners think more timing advance equals more power, but the data tells a different story. We analyzed timing vs torque curves from hundreds of dyno sessions to find what actually makes power.

Why Turbo Miatas Knock at 4500 RPM: Fixing the Timing Map

That predictable knock wall at 4500 RPM in your turbo Miata isn't random. Stock ignition timing maps assume naturally aspirated conditions, creating dangerous timing advance under boost.

What’s the Optimal Ignition Timing for E85 on Supra and 350Z Builds?

Most tuners push ignition timing too hard on E85, assuming more is always better with race fuel. The data from Supra and 350Z builds tells a different story about where peak torque actually lives.

Why Miata Intercooler Upgrades Lose Power on Stock Tune

A bigger intercooler should mean more power, but Miata owners regularly see 10-15whp losses after upgrades on stock tunes. The culprit is timing retard triggered by MAP sensor readings the ECU wasn't calibrated for.

Why Stage 2 Builds Fail: It’s Not The Hardware, It’s The Timing

Most Stage 2 failures aren't caused by faulty hardware — they're caused by ignition timing maps that ignore your engine's individual knock threshold. The data tells the real story.
