Course Instructor: Greg Banish

Greg Banish is a mechanical engineer and motorsports enthusiast who works as an OEM calibrator by day and professional engine tuner in his spare time. After studying for a bachelor’s degree in Mechanical Engineering at GMI Engineering & Management Institute (Kettering University), he wrote his thesis on vehicle instrumentation and measurement. Putting this education to practical use, he founded his own performance shop outside of Detroit and has served local enthusiasts, shops, automotive companies and OEMs.  Greg spent three years working for General Motors as the hybrid powertrain calibration engineer responsible for the Chevrolet Volt fuel economy and emissions. Now he works for Power-Tec Engineering as the senior engineer for supercharger systems.  He is a member of the Society of Automotive Engineers and SEMA.

To this day, he continues to serve the performance industry providing EFI calibration and consulting services to shops as well as authoring two books on EFI tuning. (Engine Management: Advanced Tuning, Designing and Tuning High-Performance Fuel Injection Systems, both from CarTech books’ S-A Design Series) With over a thousand aftermarket calibrations performed, he has had the opportunity to work with a wide variety of engines and control systems. He also enjoys instructing at 3Balls Racing open track events, wakeboarding, and waterskiing.

Course Description

Advanced GM EFI Training
Duration: 2 days

For those looking to take the next step in proficiency with aftermarket control of GM EFI systems, this course provides a wealth of knowledge and insight.  Before attending this seminar, it is strongly recommended that students watch the “GM Tuning Beginner’s Guide” DVD in order to build a foundation of basic knowledge of these systems.  The DVD covers the basics so that time is conserved during the seminar to properly address the more in-depth topics specific to late model GM EFI calibration.

Picking up where the “GM Beginner’s Guide” DVD left off, this course goes into detail about the more advanced control strategies employed on late model GM fuel injection systems. Students are given a tremendous amount of reference material in the course notes along with live demonstrations of some of the most complex strategies being tamed right before their eyes.  Examples are tailored toward GM specific cases ranging from LT1 GENII and LS1 GENIII systems to the newest e40, e38 and e67 GENIV ETC systems. The course goes further in depth on the GM strategies and controls than our introductory EFI course. Students are provided useful reference material that will serve them for years to come. The seminar will include several live demonstrations using a chassis dynamometer and either HPTuners or EFIlive tuning and datalogging software systems.

Benefits of Attending
By attending this seminar, you will learn to:
• Describe how the GM PCM and its sensors function
• Develop and correct base tables, MAF transfer functions, and adders on high power engines without relying upon unknown files from other sources
• Properly calibrate “Virtual VE” tables for speed density mode on newer models
• Properly adjust electronic throttle control without compromising safety
• Prevent many common drivability issues with the GM PCM on modified vehicles


Who Should Attend?
This class is for the more experienced tuner looking to learn more about the GM control systems. While it covers a brief review of the basics of EFI tuning, a strong emphasis will be placed upon working within the specific controls of the GM GenIII and GenIV systems. Professional tuners and shop owners in particular will find this course extremely useful for unlocking some of the mystery behind topics including “Virtual VE”, electronic throttle control, safety diagnostics and more. Some math is involved, so be prepared to use a calculator.
