Ok so I will be getting ECMlink here soon, and will be converting to a gmaf. And I want to know one what needs to be done to do this and well how hard is it to tune. And also how difficult it will be to install the speed density conversion kit?

Also I forgot to add this but what is speed density and what does it do?

This page has a basic description of the main airflow "metering" options for ECMLink.

It all sounds way more complicated than it really is, though. Ultimately, you're just connecting a MAP sensor to the ECU and then adjusting the VE table up or down to get things working as they should be. There are a few dial-in helpers for that too.
