I am trying to datalog fuel/oil/water press. But I have issues.
I get everything like hondata says to setup.
B2 - Logic Ground
D19 - Sensor Voltage
then A0/A1/A2 for sensor signal input.
I am using PCS 0-100psi sensors.
I get everything working at idle, but when I make a pass it is very erratic.
I run a full chassis/engine wire harness with built in sensor wiring.
I have tried eliminating the sensor wiring and running my own wiring, using the grounds off
the s300 but it doesn't change. Any advice?
Datalogging with PCS sensors
Re: Datalogging with PCS sensors
Post the calibration as well as the datalog showing the issue.

Re: Datalogging with PCS sensors
Just read this, let me give it a go...
Will upload those in a little bit.
If I pull the log off the ecu using the "Save As" function the analog sensors display incorrectly.
If I pull the log off the ecu using the "Download" function the analog sensors display correctly.

Re: Datalogging with PCS sensors
Ok finally got car back together.
Here is what it is doing:
At idle everything is good. S300 matches.
It only happens on pass.
If i do save as i get that eratic signal.
But if i download first it displays but at a less numerical value.
I.e., right before 2nd I look at mechanical gauge, it read 90, but the log, says 40.
Here is the cal and the datalog.
The pass was a transmission check, so we took it slow.
