    Default ls9 injector flow rates for ls1b

    I have a p59 ECM swapped into a 2002 z06. I am trying to get correct IFR numbers before running calc.vet. I have ls9 injectors and I hoped I could copy B4001 from a stock zr1 tune to my 04 z06 tune. Is this possible? it seems the two different ecm's use different parameters. How can I get good IFR numbers and what other parameters do I need to worry about?

    Sorry It's taken me so long to get back to this. I tried just adding a % value to my IFR, and then tried running the car. Way fat. afr in the 11's. So I thought I'd come back to IFR, thinking I had the IFR wrong. However these numbers seem huge compared to my flow rates. my lowest number is 3.6719 as compared to 6.623388. I'm afraid to even try these numbers. also the ls9 vs ls1 are scaled differently. Map vacuum vs Delta map kpa.
