5sfte rich at idle, 30% out at 1k rmp to keep 14.7 ish a/f Options

[urbandork]

my 5sfte is running rich at idle. I have to take out 30% of fuel with my safc in order to get the 13-14.7 ish a/f ratio.

set up:
255 lph pump
440cc injectors
everything else is stock

What could be causing the problem????

could having the engine retared to much at idle be the cause of the ecu not being able to adjust to a rich mixture?????

This is kinda wierd. Urban. You're fuel injectors are only 4.4% larger than mine. but even at the most negative settings (-50%) i was running like a 11-12:1 a/f during idle and when i barely stepped on it when driving it dropped to about 9.5:1 and started to bog and almost die. So mine's undrivable. Im hoping the 2 bar will help.

btw. do you smoke a lil when you're running that rich?

im using innovate wideband btw.
