I used the low a/c pressure switch. But this can be using the egr system as well.
A/C low pressure sensor method-
In the scanner, right click on the table display, and click insert. Then under user defined, click configure user defined. Select a open space (mines on slot 4) name it whatever you want, select AFR for sensor and units. Then for the function, insert this pid: " ([PID.7101]/.332)+7.35 ". This is setup for Innovate mtx-l wideband. If its off from the gauge display you'll have to play with the last number in the function. Then connect the 0-5v data logging wire from the wideband and connect it to the red and black wire from the low a/c presure switch. You'll also have to insert "AC Pressure" in the table for the function to actually work. I figured that out the hard way
The egr method is basically the same, the pid will be different and you'll have to find the correct wire to connect the data logging output to.

Wow. Holy ****.
does pid.7101 tell the ecm to read the voltage coming in on the low pressure ac switch? And the rest math to get the correct # to display?
I use my ac but in a pinch...
My car didnt come with egr but could the input still be there.
I assume I cant use the rear o2 cause its 0-1 volt?
Thats for the pid info. That will be awesome. Would suck to not be able to log my new wb

Thread on HPT's website with some details, lets you log through EGR. I haven't tested.

Which fuel pump? Here are a few short logs if anyone wants to see them.
I need a fuel pump bad. My pressure tanks <40# up top. Should I do an external Bosch 044 or an intank Walbro 450?

Fuel pump?
External Bosch 044? How loud is it?
Internal Walbro 450? How much trouble with the straw or 30r10 hose?
or BAP?
I gotta do something next week.

How about dual walbros in the stock bucket. That will give you room to grow. I used the stock evap line for a return. You can also get 97 98 vette rails that have a return.
Sweet! Glad you were able to make it work.
Here's a plug and play walbro 430 lph setup:

Bulkhead - http://www.racetronix.biz/itemdesc.a...CS-028&eq=&Tp=
Intank harness - http://www.racetronix.biz/itemdesc.a...WH-029&eq=&Tp=
It would be interesting to see how it works on your return fuel setup with the stock regulator.

Walbro f90000262 400lph I bought this pump 
and an 8.75" straw and some submersible hose from APE. I got the smaller Walbro turbine pump because I'm going to attemt to use the OEM wiring. It draws 15A and the oem circuit is on a 20A fuse. But I just checked the wiring and it looks like 18 gauge. Damn. If it melts I'll fix it then. Screw it.
