Hi all,
I have been busy updating and upgrading my R32 GTR over the last few months. I fitted a Walbro 255 along with the Nismo FPR and hardwired the pump to the battery with a separate relay. The voltage to the pump is now spot on. The stock FPCM has been bypassed.
I have taken it out a couple of times in order to check the parameters. When I checked the fuel pressure, I noticed that under light boost, the actual fuel pressure wasn't following the expected fuel pressure. As you can see from the picture, the fuel pressure increase is nice and linear but not 1:1. Am I correct to assume that this is to do with the regulation slope of the FPR? Nismo states the slope as 157x10kpa l/h. I don't suppose anyone knows what actual number that is?
Many thanks in advance!
Nick Cox
