Hey Guys,
I've spent the last few days researching turning up the fuel, and topics about the FDC (Fuel Density Compensator). If anything, this has left me with more questions than before. I will try to keep this organized, I have many thoughts running through my head.
1.) I have read (with a grain of salt) that the FDC isn't optimal for performance. I like the idea of the FDC compensating for various fuels if you were to find yourself in a situation which presented no diesel. My friends Deuce w/ the FDC still in use, runs WAY stronger (One of the best running I've seen in fact) than mine with the compensator bypassed, so I am not sure if the claim of FDC not being optimal for performance holds its weight. Anyone have any opinions?
2.) I came across this post HERE and I think the link in the post has what I need, which is a higher resolution picture of the attached diagram of the fuel pump with and without the compensator bypassed. Unfortunately the link is no good. Anyone know where to find the file?
3a.) Before I realized my truck had the FDC bypassed, I went and turned up the fuel via the FDC (I turned the nut a full turn). There was a noticeable increase in performance. After I went to lock down the settings, it was then apparent my truck had been bypassed. Now from what I have read, tuning a bypassed FDC should have no affect on performance. Can anyone confirm or deny? (If confirmed, I must be going crazy).
3b.) If turning the screw on the top of the IP on the FDC will not affect performance, what is the way to adjust fuel delivery with the FDC bypassed?
I think that should do it for now...
THANKS!!
