    Need bin for 1227747 BCC ADYS

    I have been doing some data logging, trying to track down a rough idle upon warming up. Idles fine at cold start. Runs rough under load. EGR, EGR solenoid, Map, ESC, knock sensor, cap, rotor, plugs, fuel filter, and newer fuel pump have been changed. Down to distributor, tbi/injectors, weak new pump, maybe failing fuel pressure regulator. No codes. The vehicle is a 1988 V20 Suburban, it is a LO5 350/SM 465. I have tried a few bins for the manual burbs but im getting an extremely high injector duty cycle 200%+. I have tried two of the manual bins offered on here (ANMW & ASDW). I still have ARHT and ACSC to try. Any help would be appreciated. I will post some log files once I get a bin displaying proper feedback. EDIT* using TunerPro RT and ALDL cable from ALDLcables.

    Thank you Dave, I'll give it a try. All the bins I could find on here gave me the super high duty cycle on injectors. Doing some reading on here, I gathered that is because I am not using the correct bin. Is that statement correct?

    Turned out to be a blown head gasket. No coolant in oil, lost compression between 3&5.
