I've been struggling with transient fuel in my car, a G8 GT with TVS 1900 supercharger, LS9 injectors, long tubes, and intake. I have lean tip-in and rich tip-out, especially when the engine isn't up to temperature.
The MAF table is tuned well. I thought that it was an issue with VE, so I VE tuned it under 3000 RPM, but it made absolutely no difference for the lean tip-in and rich tip-out conditions. I have modified the transient fuel tables, but they have acted somewhat unpredictably.
Then I read that about half of all transient fuel issues are related to the injector data. Comparing my injector data with that of a CTS-V with the same injectors, I have noticed that there is a difference in the injection timing boundary table, Normal RPM injection timing table, and makeup pulse minimum table. Can anyone confirm whether or not I should be incorporating these? I believe that the injection boundary and normal RPM timing tables are related more to the cam and wouldn't need to be changed, but I'm not sure about the makeup pulse min table.
Anyone?
