XFI fuel logging/oil pressure connection????

Hello all sorry for the newbie question but I'm in the process of hooking up the oil/fuel pressure sensors for logging on XFI. So the question here is where in the heck do these sensors connect too??? also last dumb question what do I need to do to get boost to read on my edash? Is there a special sensor I need to purchase separately?

I don't use an e-dash. But I'm guessing you don't need a special sensor. You already have a MAP sensor. Must be a choice on a menu.

As for the pressure sensors..........
I wired them directly back to the XFI box, after the Casper's box. Find the slots in the harness plug that apply by looking at the harness plug diagram in the XFI help menu. Sections 2.0 and 3.0. You will need the crimp-on pin connectors to go into the plug. I called them direct and ordered them.

Thank you for replying. My question is where are the actual sensors suppose to be mounted to on the motor? Here's a pic of what I got . I have the other sensor put away still.

The oil pressure sensor can go in same place as the factory oil pressure switch. Down low on the side of the block along the passenger side of the front cover. You will need to be creative with a fittings.

The fuel pressure fitting will need to be plumbed into the rail using the same technique.

Or you can T off those locations and use braided lines to locate the sensors where you please.

There are many options. However, they may be "plug and play", But they are not "plumb and play".
 
Ahhh Ok that makes sense. I don't like the idea of plumbing into the rail. Only because I dont want to see a bulky sensor sticking out like that. I'm thinking as you mentioned T off the rail. Did you do this? Any pictures to get a better idea?

Use this ^ and its a straight forward deal. Ties into the EGR plug and you go into the caspers XFI interface box and move two jumpers and then set up the xfi and your down.

As far as the PSI goes the MAP needs to be hooked up to the XFI and caspers makes a connector that makes this easy. The factory MAP sensor should be replaced with a 3 bar and the XFI setup acccordingly.

Mounting the sensor off of the rail / motor helps eliminate vibration to the sensor for longer life .

Ok I got everything all hooked up but my edash is still not reading reading the oil or fuel pressure. Is there something I have to do or a setting I need to change on the edash to start getting readings? I did move the 2 jumpers I plugged into the egr harness but no luck??
 
Anyone have any ideas why my edash not reading my fuel/oil sensors after getting it all hooked up with the caspers plug and play harness that connects to the EGR plug????

Now that's a mean sleeper.

But I already seen what NY Twin Turbo's motor looks like. That's why was wondering where he was hiding his sensors because it's one clean motor with all the stuff nicely polished and everything hidden very well.
So technically, if you didn't want anyone to see it, you can T-in a fuel pressure sensor anyplace along the fuel supply line between the pump and the regulator.

Do you have oil and fuel psi checked in your XFI? You do have 2.05 right?

Did a few upgrades huh looking good
Customized special spot on the steering wheel were my hand fits just perfectly. Special foam colored headliner. Custom (flexible) interior door handles.

A whole bunch other stuff not pictured above. You should see the exhaust!!!!
