ECMLink 101
WORK IN PROGRESS
This page is intended to orient the new user to the ECMLink system and, to some extent, ECU tuning concepts in general. If you just received your package and really have no idea where to even start, this is probably the page for you. If you already know how to tune an ECU and already understand basic engine operation and how to use the ECMLink application, then this page is probably not for you.

General Concepts
Engine and ECU 101 - You need to have a reasonable understanding of engine operation and ECU tuning concepts. If you already have an idea of how airflow and fuel flow and timing work together in an engine, then you can skip this page.
Speed Density 101 - Everything you need to know to get a jump start on speed density operation with ECMLink.
Fuel trims - Really understanding fuel trims and how they are used by the ECU can help immensely in fine tuning your setup.
Adjustment Functions and Dial-in Tips
TPS Adjust - One of the first thing we like to suggest is that you get your throttle position sensor adjusted so that the ECU is happy with what it sees. You can use this helper function to do that.
MAFComp Adjust (CombinedFT) - If you're pretty sure the fuel setup is correct, then you can try letting the laptop application make a set of suggestions to the airflow curve for you. Try to use some common sense on this one, though. If the suggested values are all over the place or just don't make much sense to you, don't use them.
Quickie A/F setup - If you'd like to adjust airflow a bit yourself, you can use this page for a few more tips on using fuel trims to fine tune your setup.
