Well I made my first few pulls on my car today, and decided to log the runs. I was running a minimum boost level of 12psi. But, I am a little confused about the readings that I am receiving back. At one point during the log I am showing that my Injector Cycle Duty was 94.3%. Does this indicate that I was running my 550s to nearly 100% of their capacity?
If so, I dont understand how that could be. I use to run 450s pushing 15psi with no problems. Now, I did change to a ported 2g Exh mani, Small 16g, and larger exhaust. I do have a 255 walbro that I have not installed yet, but I thought I would be ok on the stock pump until I hit higher boost levels.
Also, when I do install the pump, I dont see how that would lower the duty cycle. I still need to dump as much fuel into the cylinder?
Last point. I do have an S-AFC waiting to go in as well. I am guessing this would really help b/c I would be able to pull fuel out and lower the duty cycle if EGTs and knock counts allow it. Any help would be appreciated. Thanks!
