Logging FP on a P01 ECM and a Pro Link

[JumboShrimp]

My set-up is a MPVI2 with Pro Features and the Pro Link wire.

I have a GlowShift 100 PSI FP gauge. It is in a 03 Z06 - I have No built in FP logging in that ECM. I am currently using the Red wire on the Pro Link for a GlowShift WB O2 and it works.

I want to use the Blue wire to log FP. I tested the output of the FP sender and it matches the enclosed chart so I think it 'should' work. My question(s) - The Sender's V Out Put runs .5V = 0 PSI -> 3.2586V = 100 PSI. According to the chart they sent me. It doesn't go all the way to 5V.

Does it matter that is not a 5V sender? Is the software looking for 0-5V or can I get away with using this sender's <5V output?

Also, Can anyone suggest the correct user defined Math formula so that it works? Wiring it will be the easy part.

My other (more work) choice would be to get a true 5V sender and hook it to the fuel rail at the Schrader Valve Port.

Thanks for any help.

If you can get it reading the voltage I don't think it matters the range.

Formula should be P=36.243xV-18.127

Thank you for the reply! I kinda thought that was the case - makes sense. Now I just have to wire & test it before it snows.

I probably should have said the range doesn't matter as long as you don't exceed the limits of the device. Lesser voltage should be ok.
