This book explains how the EFI system determines engine operation and how the calibrator can change the controlling parameters to optimize actual engine performance. Engine Management: Advanced Tuning takes engine-tuning techniques to the next level. It is a must-have for tuners and calibrators and a valuable resource for anyone who wants to make horsepower with a fuel-injected, electronically controlled engine.
Author Greg Banish is a calibration engineer with extensive aftermarket performance calibration experience. He has a BSME from GMI Engineering and Management Institute (Kettering University). With over a thousand unique calibrations performed over five years, he has worked with enthusiasts and OEMs alike to improve the performance and driving behavior of a wide range of vehicles.
The book contains detailed equations, graphs, and illustrations. Also included are valuable and practical examples, including real-world examples based upon the author's experience that will help more advanced readers apply this new information to situations that are commonly seen during calibration.
