So I'm trying to log back pressure and I've hit the edge of my knowledge with HP Tuners.

I am using three of the inputs. #1 is my wideband, #2 is my fuel pressure and # 3 is my backpressure.

I am using the pre-set "transforms" and selecting my sensors. This seems to work ok when setting up the channel as I can select the input I want to tranform.

The problem I run into is when I set up a gauge or a graph. I cannot pick which input I am transforming. Or I cannot see where I can make that selection.

So say I add a gauge for backpressure, I select that transform for the aem 0-100 psi sensor. It appears to be summing BOTH the sensors I have in the inputs. Which makes both my fuel psi and my back pressure non functional.

I'm gonna get on my PC laptop and add a log and my scanner layout here in a sec.

Any help would be mucho appreciado. I know I'm overlooking something basic.

here is a log from a recent run. I'm logging backpressure in volts.

also included is my scanner config.

So I figured out a reasonable work-around. I set my drive pressure sensor up in a channel as a user defined input. I used the same PID as used on the AEM sensor which is V/.04+(-12.5)

then here's the sneaky part. I call that sensor something else so i can reference it in gauges and charts. it asks for a parameter, so I chose a pre-set PLX boost/vac sensor.

It automatically input range and dial info into gauges and charts so I changed that to match my sensor and it appears to work fine. Tested it out with shop air to 50psi.

However my MAP sensor decided to quit working
