I have an autometer fuel pressure sensor, and can't get support.

[The Alchemist]

I posted in that gigantic release thread about not seeing support for the Autometer fuel pressure sensor.

Kevin asked if I could get the data for it, he'd add it to the next release, but I have yet to be able to find anything.

The thing is, it was supported in 2.24, so I'm sure they have the data in the archives somewhere, it was a select-able option before.

This is the sensor I'm using, and like I said, it was supported before.

To me, fuel pressure is just as critical to monitor as afr, timing, etc. I log every time I drive, and I want to make sure that fuel pressure is staying where it's at with ~900rwhp.

Thanks.

It's a 0-100psi sensor on a 0.5-4.5v range. The transfer is as follows:

Pressure = V * 25 - 12.5

Just use the AEM 100psi sensor built into the scanner. It's the same sensor.

I believe the transform you want is already in the software, under Pressure Sensors->AEM: AEM (PN 30-2130-100) 100 PSIg

Thanks for the replies guys. I'll try the AEM sensor and do some data logs and see if they are comparable to what it was previously... it should be.

To the same pressure measuring question: I get that formula "Pressure = V * 25 - 12.5" put into scanner V3.2 by putting "(1/25)-12.5" to the equation but how do I ad "*0.0689475729" to it since I need that to transform psi to bar.

It seems it's always a must to choose a parameter when adding a channel. This choosing a predefined parameter retrieves a name to the parameter list that I would like to change but I can't.

You don't have to. Use the correct formula for PSI and chose a unit of PSI when setting up the transform.

Then when you're using that fuel pressure parameter in charts/graphs/gauges there will be a box for what unit you want to use. Select bar or whichever unit you prefer and it will do the conversion for you

Or you can just multiply the whole psi formula by 0.0689 to convert it over to bar that way.

I think the former is easier.
