Engine Tuning: The Ignition Guide

by

Knowing that engines produce power by harnessing the dramatic pressure increases resulting from the ignition of the air/fuel mix, let’s take a look at how that pressure plays into the calibration requirements. Cylinder pressure is directly related to engine efficiency and output. Engineers often refer to BMEP, or brake mean effective pressure, to describe engine […]

Engine Tuning Outputs

by

Now that the inputs to the computer have been covered, it’s time to look at what the outputs can do. Not that many outputs are required to operate most engines. The advantage of EFI is the ability to very precisely control each of these outputs. Think of jet changes in a carburetor as strokes with […]

Engine Measuring EFI Inputs-Best

by

Before we delve into the tables that control engine operation, it is important to understand what the computer sees. The old saying, “garbage in, garbage out,” applies directly to EFI systems. More often than not, the cause for a poor-running car lies not in a bad calibration, but rather in a bad calculation. This is […]

How to Design and Install a Turbocharger System: Step-by-Step Guide

by

Up to this point, we’ve discussed the turbocharger apart from the engine. However, adding a turbocharger to an engine is more than just choosing the turbo for your projected horsepower output. The turbo “system” includes all of the ancillary components that adapt the turbocharger to become “one with the engine.” This is the philosophical approach […]
