    Question new injectors (fuel consumption increased)

    Hi all, i from russia, need help setting up fuel consumption
    i have Clebrity `88 replaced its 2.8(lb6) on 3.1 (lho) ecu - 7730 (bin arxw)
    replaced old injectors (Rochester / GM 5235136) 15.22 lbs\hr 160cc 115.0 grams
    on new Bosch injectors (0-280-158-110) 15.35 lbs\hr 161.3cc 116.0 grams
    I badly write in English understand and forgive)))

    I understand that these injectors are different mechanism. new injectors plastic and wery speed open
    while older injectors are slower opening....
    the question is what you need to change in the bin to adjust the opening time? and what parameter is responsible for this? which parameter is responsible for dwel time ingectors?

    Welcome! Would love to see more of your Celebrity and its story of how it made it to you.

    We don't have many members here that do that sort of work, as I assume you are needing to burn a custom BIN from your ARXW EEPROM. I haven't quite gotten their myself either with my non-A-body projects, unfortunately. However, the Third Generation Camaro forum, https://www.thirdgen.org/forums/ , is very active in this area. Since the Camero and Firebird (F-body) were both available the same family of 60 Degree V6 engines, and used the same problematic (first generation) Rochester Multitec injectors, I'm sure there are resources over their.

    Again, WELCOME and please let us know more and if you find the information you need.
