Thread: 500 lbs/hr on 80 lb/hr injectors?

  1. #1

    Default 500 lbs/hr on 80 lb/hr injectors?

    So I was looking at a datalog tonight, and I was trying to figure something out.
    How is it possible that my AFR is matching, but the CL Comp is 100% and pushing 534.3 lb/hr fuel?
    The engine is a 383 Chev, Terminator setup with laptop tuning. 700R4 transmission, 4.10 gears.
    No power adders. Suggestions please? I'm thinking bad WBO2 sensor, but what do you think? Thanks.

    Yes, that seems like a failed WBO2 sensor, or an exhaust leak upstream of the WBO2 sensor.
    May God's grace bless you in the Lord Jesus Christ.
