I noticed today when looking at a datalog in MLV that my max duty cycle (DutyCycle1) was 107. I'm taking that to be a percent, correct? Upon further inspection it appears I'm typically around 80 toward the top of the rev-range, then on some pulls it will jump to 95+ (often the datapoint before I left off the gas). Is that normal or should I be concerned?
A 3rd gear pull, last 7 datapoints
Duty Cycle: 81.1, 80.3, 78.8, 81.9, 80.3, 104.1, 7.2
I'm running a MSPNP, 550 RC injectors, and a stock fuel pump. I dyno'd 262, 240 a few weeks ago. I haven't had any problems leaning out or anything, air/fuels have been consistent and reasonable. If the high duty cycle is a problem would a fuel pump be a wise investment? From what I've read a Walbro 190lph seems to be the most popular on an NA.
I can post a datalog tomorrow if you guys want to see it for yourself. I'm a little embarassed of this one, I was working on interstate (high rpm/low load) stuff that I haven't really messed with much and it's not pretty.
