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.

“Secrets
of EFI Calibration” Seminar
Duration: 1.5 days
The engine control unit (ECU, PCM, ECM, EEC, DME)
is the computer that controls engine operation including fuel injection,
ignition timing, and other functions. Proper "programming" of the
PCM is required to achieve the desired performance behavior of the engine.
This calibration is done by factory engineers for stock engines. Changing
hardware components on the engine often requires a recalibration of the ECU
to allow the engine to operate most effectively.
This course provides background on the physical operation of the engine
and how the sensors relay this information to the ECU. It answers the
questions often asked about how the ECU uses these inputs in determining the
proper outputs to yield the desired air/fuel ratio, spark advance, and power
output. There is an emphasis on taking an engineering approach to ECU
calibration and getting the right result for the right reason.
Think of it as a crash course in mythbusting many of the Fuel Injections lies being told
on the internet today.
Examples are tailored toward the high performance tuning industry using both
reprogrammed OEM systems and popular "stand alone" aftermarket
systems. Discussions will range from domestic V8s to more exotic forced
induction 4 cylinders. Since the same principles apply to a wide variety of
engines, students will be able to apply their new knowledge to just about any
EFI project. The course goes further in depth than most basic clinics.
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 the latest aftermarket tuning software.
Benefits of Attending
By attending this seminar, you will learn to:
• Describe how the engine and its sensors function
• Explain how the PCM uses the sensor inputs to determine fuel injection
and timing
• Interpret base fuel and spark tables
• Develop and correct base tables and adders
Who Should Attend?
Anyone interested in the operation of the PCM and engine calibration. This
course will be of particular interest to those looking to tune their own EFI
systems or those who tune professionally. This course has also proven very
helpful to many service technicians who need a better understanding of ECU
operation for diagnostics and repairs. Some math is involved, so be prepared
to use the calculators we provide in the class.
