safc on 3sge....Dec. air? what is on yours? Options

[RDL888]

i know this function wont work if the Thr is on ****
so i tried Thr:*****
Ne1: 0%
Ne2: 0%
after a min. of idling,the engine would get so rich it wont rev smoothly,then i brought it back up to 15% then it went away,so i guess even on **** it still works.
so....this function controls fuel?or air?


what value is on your dec. air?

[fgvillegas]

dec air is used with forced induction specially when you experience engine stalling when you let go of the throttle.

in my case, since i'm using an n/a engine, i used the default setting:

Thr:****
Ne1: 0%
Ne2: 0%

if you have an n/a engine, i suggest you also leave it that way.

when Thr is ****, the deceleration parameter is not functional. i'm not sure why yours is getting rich. btw, how do you know you're running rich? do you have an afr gauge or something?

as to whether the function controls air or fuel, from what i understand, it's both because it goes hand in hand. the % value you enter is added to the air pressure value that the ecu is suppose to read that's why the box will control the fuel based on the this reading.

btw, i'm a proud pinoy too! welcome to the forum.
