i am using live edit to make changes to the fuel / timing maps on my sr20de ecu
for some reason the ecu feels the need to make the car idle on a 10 a/f ratio
and not the usual 14-15 a/f ratio
not sure what I am doing wrong so need some help pls
I have made changes on the main fuel map between tp8-19 and rpm 800-1600
Varying between 14 a/f ratio and 18 a/f ratio
the car only uses these changed values on start up ( first couple of seconds from start up hot or cold) then it goes to being rich (10-10.5 a/f ratio)
i am not sure what else the ecu uses to calculate what a/f ratio to go for
what am I doing wrong ?
all I want is the ecu and wide band to get to the same a/f ratio’s
but this just don’t seem to be a easy task
The fuel map should be close to right when you got it depending on what program you are using, but idle maps are usually pretty similiar. If your a/f is not what it should be then your K value is out. K value determines everything, it needs to be changed for what maf and injectors you are using.

thanks any ideas on what the k value should be for Z32 maf and std ve injectors ?
