Thread: HPT trouble with histogram of Wideband

I am using my EGR to log my Wideband o2 data in HPT. It shows up in the charts so i know it is logging. But i can not get it to come up correctly in the histogram. My current setup is as follow.
Plot Value:
Sensor: blank
PID: WBegr
units: afr
Decimals: 2

Row & Col Axis

MAF Airflow vs Output Frequency

Secondary
Col(Top) Axis Header
Sensor: Mass Air Flow Frequency

Row(Left) Axis Header
PID: WBegr

Im pretty sure its in my Row & Col Axis that is wrong. Any help would be great.

You need to have egr voltage and egr pid logged or the pid wont work

Do you mean after i add the EGR position, WBEGR and EGR AFR Error from the steps i followed here?

Then i need to drive the car around to get a log, if so then i have done that. I am new to this so bear with me!

He's saying that in order for your wideband PID to work, you must log the EGR volts in the table display.

Because the PID you made is getting power from somewhere and the VCM scanner needs to see that voltage. So your EGR is the power source and all you PID info comes from the EGR, so it must be logged in the table display to produce data.

This is what i have in my table right now.

Yea thats right. So whats the issue? You just set your histogram to the same settings as that pid iirc.

Give me 1 minute ill grab you my settings.

I have ny histogram set as follows

Name: Maf wot tuning

Pid: wideband ( this is my user defined pid name)

Units: :1
Decimals:2

Value high 20
Value mid 0
Value low 10

Mine is the same except under units i have afr, what do you have under row & Col Axis?

I figured it out now, thx for help!
