E85 Injector Sizing for Supra: Why 85% Duty Cycle Matters
E85 injector sizing isn't about maximum flow capacity. Most Supra owners oversize by 30-40%, which destroys atomization and makes tuning a nightmare.
Why Your MX-5 Turbo Boost Oscillates at High RPM (PID Fix)
Your MX-5 turbo hits target boost smoothly at 3000 RPM but oscillates wildly at 6000 RPM because your PID controller can't handle changing exhaust flow dynamics. The solution isn't more aggressive tuning, it's understanding why single PID gains fail across the RPM range.
DIY Boost Controller Setup: The 30-Second Test That Prevents Engine Failure
Most DIY boost controller failures happen within the first week, not from bad tuning but from basic installation mistakes. A simple 30-second pressure test catches the leak that turns 18 PSI into bent connecting rods.
Honda Civic Si Boost Creep After Intercooler Upgrade: Fix Guide
That new front-mount intercooler might be sabotaging your boost control. Better cooling creates denser air, more backpressure, and boost creep past your wastegate spring pressure.
Why Your Stage 2 WRX Boost Spikes: 3 Sensor Readings That Reveal Wastegate Failure
Stage 2 WRX owners know the fear: random boost spikes that shouldn't happen. Three specific sensor readings in your datalog will reveal wastegate actuator failure before catastrophic damage occurs.
Why Electronic Boost Control Fails on Modified Subarus
Most Subaru owners chasing boost control issues throw money at wastegates and solenoids when the real problem is in the tune. Your duty cycle tables are probably mapped wrong, and the data will show you exactly what's happening.
