Al,

My fuel pressure regulator (Airmotive) is getting its MAP from the two small (1/8 “) tubes that lay in the primary ports on the Renesis…Are you saying that I should move this pressure reference to someplace else?  You say you know it is not good…How do you know this?

Gentlemen;

Getting ready for plumbing, initial wiring, gearing up for first start.  Where is the best place to locate a MAP sensor in a turbo 20B, in the air box, or closer to a port?  Are there any hard and fast rules about this?

Greg;

Closer to the ports gives you lots of pulses in the signal.  I expect this is not good for the ECU, and I know it is not good for the MAP referenced fuel pressure regulator.  The MAP sensing is close to the ports on my setup, and I had to install signal damping.  I don’t know your configuration, but if you have a single TB feeding an air box, I’d put it in the air box.
