So I installed some AMS 780 injectors purchased from a member on the forum, and used the settings covered in the latency/scaling thread. According to my OBD II scanner my stft is 4.69% and LTFT is 1.59%, on EVOSCAN 2.0 im showing 120 on o2 feedback(stft) and 108 on ltft. This is all at idle have not driven the car yet. Are these ballpark numbers for these injectors and is the OBD II scanner or evoscan more accurate. I have a wideband enroute and will test afr's etc when it comes in. I used the setting privided by BEZ, with the 609 scaling. Seems to start and idle fine.

Those numbers are all very close to incheck. Thats odd they have the varience like that, I can not explain that, because they both are reading from the point; maybe the intervall time between using the scanner and evoscan was over a few minutes causing the trims to adjust slightly. Your stft's could be tweaked slightly based on evoscan. reset the trims again and see where your at after 20 minutes of idle

So now I am playing the bracketing game I see why this is frustrating. I idled for twenty minutes, got 112.5 on STFT, low, went for cruise and my LTFT mid hovered at 100 percent, increased latency and got idle down to 100% after twenty or so then my cruise was at 82%, so now I am increasing the latency again got the low/mid to 88%, 76%, upped scaling and now my cruise is back at 76% and idle back at 98%. I can see this takes some time. My lap top died doing this today, on charger so i can start over.

Ok back after round 5 or so. Wound up at scaling of 736 cc, and played with latency some more, let her idle twenty to thirty, %103.4 on short term, lt, cruise was 98.4%, and my o2 feedback is between 97-107 on most readings. Should I stay here or increase latency the next minimum value. I feel that where it is now I will prob leave alone and log for the next few days see if it holds.

any of the gurus care to chime in?
