Megasquirt question

Post by nos92mx3 »

Wondering what wire you guys tapped into for the ignition switch.
I have still yet to wire that or the fuel pump and was also wondering if i could let the stock computer handle all of that?

I'm guessing this question is for your rs-t (4 cyl application) ?

remember that whichever one you tap in to has to have power DURING CRANKING. use a test light to figure it out. also, i dont believ you can use the stock ecu to run the fuel pump because it turns the pump on when it sees crank signal and since ms is going to be stealing your crank signal the fuel pump will never turn on.
