Who has the Outlook Monitor?

[Matt400]

Its my understanding it will read rail pressure and I am curious to know how high of pressures have been seen on the Outlook?



I have been doing some testing on a rail pressure gauge application using the OE pressure transducer, had it all nailed down- works perfect for a "no box" application and then ran into trouble with a box. .



Seems fueling boxes on these applications take that same transducers signal and purposely pull it down to "fool" the ecm into providing more pressure, that would make the gauge also fooled on applications with a box.



I should have known that but what I thought was the box manufactures would read a true signal and then input to the ecm a false signal rather than "pull down" the entire circuit. With this in mind I dont see how the Outlook Monitor could output a true pressure reading.

Back to the drawing board

It doesn't. The Outlook has the same problem your having. My Outlook will display roughly the same pressure readings regardless of having a pressure box on or not. It is kind of a gee-wiz useless feature. I don’t even look at it. Pressure boxes do "fool" the signal, hence why the ECM does not complain when pressure is raised above the norm, but also the pressure sensor itself has a readable limit and is not capable of displaying pressures as high as some of the pressure boxes take it. Kind of a catch-22 with two problem fronts that you may find difficult to overcome. I think forum user "DLeno" has done it accurately. Might get some info from him through a PM if he doesn’t see this and reply.

Actually most all pressure transducers have a built in safety range of double its intended range. Manufactures wont print this so its a verbal known. I found that I could program in the CTD's transducers specs into a SPA dual gauge with the high point of 26,107K and 4. 5v that the gauge would keep reading above on up to 5. 0v which is the supplied voltage making for a 30,000 psi readout.



The limiting factor I found is the supply voltage of 5v but at 30K not much reason to read past that. Thanks for the info on the Outlook, I thought it may be that way.

Uhhh... wait a sec??

When I was testing it all I had left my DVOM back probed into the

vehicles OE transducer connector when I swapped in the box.



Ryan was kind enough to point out my mistake. I went out for another road test back probing the boxes connector at the and transducer wallah!! I was able to read actual rail pressure as I adjusted the boxes power levels.



I'm such a dork!
