As I was going through the tune I modified the timing table as suggested. I do have a question. I updated tune for the 100 lb injector rate. I also updated the displacement value for the engine. I calculated what BPW needs to be with the new flow rate and engine size. I entered the new BPW in the tune in the cold start parameters. I am curious why I need to enter a BPW when I'd think the computer would calculate this based on injector size and displacement?
Is the cold start BPW its own value so that a program can increase fuel at startup?
I think the factory has it set to some value near 134 with 61 lb injectors. My calculated value with 101 lb injectors is closer to 82.
