Trying to tune, possibly bad injector?

[zachakagoat]

Ok I just got my SAFC1 wired in today and was going to try and tune it and from everything I have read when you have the 450cc injectors you shouldnt have to do much of anything with the STFT or LTFT but on mine however it said STFT was adding about 17 at idle so I go and add on like 22% to the 1000rpm range and then it FINALLY gets my STFT to stay at about 0.

Last week I got a CEL Injector Circuit Malfunction, I took my logger and cleared the code to see if it would come back and it hasnt yet but could this mean I have a bad injector so it is leaning out my readings? How would I check for bad injectors and does that fuel injector cleaner stuff work or am I gonna need to take these out completely and clean them via VFAQ

Well when I was wiring up my resistor pack I had one wire that was getting a bad connection or loose or something. I got the same CEL and it only came up once every week or two. Check your wiring around the injectors, and make sure the connectors for the injectors are full pushed onto the injectors. BTW, what injector does it say is bad? Could help narrowthings down, mine said Injector Circuit Malfuntcion Cylinder 4 or something to that matter.

O and check your plugs, if you have a totally bad injector, your car will be running on 3 cylinders and you should have one plug that looks cleaner then the rest..

No I'm not positive which injector it said that it was, it DID say which one I just don't remember. There is no way this should be right me having to add 24% (that is what I got 1000rpm) set at to keep it level. Does anyone have a link for testing injectors?
