Evo 560cc injector idle issue

[ilian51378]

I know I am reviving this very old thread, but I just installed Evo 560cc injectors and I have the same idle AFR problems... I jacked up the idle a bit and was able to get a somewhat consistent stoich AFR. Otherwise the car idled beautifully, even when the idle was low and the AFR numbers were all over the place. I have a request though - could someone who used to run or is still running those injectors with a SAFC, share with me the correction values for low and high throttle on the SAFC? I know that every car is different, but I would just like to start out with good base settings to keep things safe... I know the theoretical difference between the stock 360s and the 560s, but if I could get more "tuned" car values, that would be great! I am running Walbro 255, 15Gs and a SAFC2. Thanks in advance!

You cannot get it to idle stoic on evo 560s without a flashable ecu or aem ems.

I have achieved a stoich idle for 95% of the time through raising the idle. What would be the consequences if the idle wasn't stoich though? Thanks for the response!

nothing, but increased fuel use, if its within reason. If it goes too rich it can foul the plugs.

Well, mine goes down to 13.8 on rare occasions for a second or two, but that should be fine. I am about to install NGK Irridiums, one number colder than stock. I am planning on gapping them to .30... Is that okay?
