working on tuning the lancer with the safc.

who has tuning points and tips for tuning with it?
i found an old post by maximum17... hes running super lean im thinkin i dont want to even cme close to his map.. so pehaps ill cut 2/3 of his points on each rpm point.

at what point is higher octane needed?

thanks guys!

 

Just start subtracting. No one will have the points that work for you. I have a 190 pump and a fuel pressure regulator but no gauge (beats me what the actual pressure is but it works so..) and the MAS screw is backed out pretty far on mine + no cats.

On the much maligned narrowband I have it so I am in the yellow on cruising and 1-2 bars green WOT. I pull 33mpg with this setup on a 5spd. I also have an EGT which at 75-80mph (cruising speed on the way to work) is a hair below 1300 degrees.

EDIT: I still use 87 octane too. You'll notice the car wakes up the more you subtract too.

 

so tuning na, with no wideband whats the safest amount i can subtract?

im getting a wideband in a week or so.

 

The narrowband will read lean. Subtract until it reads in the high yellow while cruising and a bar or two green under WOT. There is no magic number. Mine change from summer to winter.

 

thanks. i just trimmed 3-4% less fuel and i feel the difference already!!!
