Two day Tuning Seminar:
"Introduction to EFI Calibration" by author Greg Banish
Where:
Speed Industry LLC
1668 Thorncroft
Troy, MI 48084
When:
June 21 & 22
Cost:
$550 per person.
Limited space available. Lunch will be provided.
Day 1: Theory and class room lecture, some dyno work
Day 2: Dyno tuning
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 also covers 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.
Examples are tailored toward the 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. Some math is
involved, so be prepared to use the calculators we provide in the class.
