What the fuck do you have injectors for?

What the fuck, are you trying to blow your motor? Get a real tune.

What the fuck, KA's don't have headers.

What the fuck, Ka's are SUPPOSED to idle around 700rpm.

what the fuck

what the fuck

what the fuck

On my car I increase the fuel at idle to stabalize it. Don't know about your situation...what does your af gauge say?

was it running fine before you dicked with the car? and if its running fine without the afc you probably have it hooked up wrong. imo

how are you measuring your A/F ratio?? an safc is useless unless you know what kind of fuel ratio you have while you're tuning it. you're probably runing too rich with the 370cc injectors and a stock maf. Get a wideband or measure the voltage of your O2 sensor to find out if you are running too rich or lean.
