Ok my setup is in sig. but am wanting some opinions on maximum or best timing , in idle , without surging and poor idle . Just trying to get best idle and fuel economy.

 

I think stock is 20, I'm running 22 right now without a problem, it could probably handle more. I have a cam though so mine might be a touch different. I'm really not sure with yours being turboed etc...

yeah that is about where mine is at now..i think i had added a degree or two when i first started playing with it.The way i look at is the timing in idle should be no different than a n/a car.might be a little different with a supercharger depending on the head unit and such.but anyways anybody else have any input on this?

 

Once idle is solid, move the timing around and note MAP readings. Try and get the MAP readings as low as you can.

 

ok should i change the closed tps table or the main spark advance table?
