This thread's goal is to familarize the reader with setting up their megasquirt and beginning of tuning to warm-up and advanced tuning. most of the information can be found in the megamanual and will probably be a reiteration. However, I find that now that I have gone through the process I can simplify and clarify. I'm currently enrolled in a Techincal Writing class, so this is also some decent practice. The reader must be familiar with terms and have at least breezed through the megamanual; besides a basic understanding of mechanics and computers. This will not cover the mechanical setup of your fuel injection you can search how I did mine under "how to TBI" or research the more work intensive part of this project, this will solely cover what I have done and the phases should be coverd in thread posts and will include the steps.
Connecting Laptop
Communications -> Settings
Under Port select which comm you believe you have most likely plugged your USB into, than select test. If failed select another port; other symptoms include setting the serial data rate at 9600 and 75msec time interval.
Setting TPS
Tools -> Calibrate TPS
Instructions are pretty straight forward though an important step.
Setting Constants
Setting up constants will be where you will start at, this can be found under basic settings. Insert values on the main page first according to you set-up, it should look similar to the picture below. Next, click on the Required Fuel and insert the size of your engine and injector flow.
Note: The PWM setting are set on either high or low impendance injectors. This setting is based on current with high often being greater than 10ohms and low less than 4ohms.For high impendance insert values 25.4 msec at 100%, and for low insert 1 at 30%. For Opening Time and Battery Correction I suggest copying the values in the picture above.
