wideband a/c pid question

[6speedterror]

i hooked up the w/b to the ac input and when i scan i get a message that says " unsupported parameters" but if i scan the a/c volts as well it will give me the reading for the wideband, anyone have this problem as well, or is that the way you are supposed to run it

Did you close & re-open the scanner after making the custom PID?
Most of the time that fixes it unless you have something wrong with the PID itself.

yeah i did restart it and no reading but if i log ac volts then it works. i copy pasted the one on the sticky but i dont know if i was supposed to make additional changes.

[EC_Tune]

Could be. I'd have to see the formula to see what "could" be wrong. Mind posting it?

this is what i used ([PID.7101]/.625)+10 but now that i chek it i was not able to program the lc1 like specified to 0v to 10.1 and 5v to 18.1

[EC_Tune]

You may want to reduce the range of the LC1 to 11-15 AFR which makes your custom PID: [PID.7101]/.8 +11
Make sure to set the Sensor Type of the custom PID to Air Fuel Ratio or it won't work.
Then just put it in the Table Display and you're good to go.

thanks will do, i still have to reprogram the wideband output right?

[EC_Tune]

Correct with Logworks.

This is by design. Since you're plumbing the wide band into the PCM through the AC pressure sensor signal wire you need to be logging AC Pressure volts in the table to be able to do anything with it.

Ahh a very important point 5LE!
