This page describes the basic process for getting your car setup for speed density operation with ECMLink. If you need a more general speed density tutorial, then the Speed Density 101 page may be what you're looking for. In fact, we're going to assume you already know everything off that page as we discuss items below. So it might be a good idea to read over it even if you're already pretty familiar with SD in general.
The first step is to connect your sensors to your ECU. You'll need a GM IAT sensor and an absolute pressure sensor. The following table lists the supported sensors.
Sensor | Desc/part number |
---|---|
GMIAT | GM Intake Air Temperature P/N 25036751, pig tail 12102620 GM Parts Direct |
GM 3-bar | GM 3-bar P/N 12223861, pig tail 15305891 GM Parts Direct |
GM 3.3-bar | P/N 9373269, pig tail 88987997 GM Parts Direct |
AEM 3.5-bar | AEM 30-2130-50 (50 PSIA / 3.5 Bar) |
AEM 5-bar | AEM 30-2130-75 (75 PSIA / 5 Bar) |
