I use the dm6 afr for tuning. Now when datalogging via crome, i am able to get all the data except for afr. I know i can always check my wideband gauge but, id prefer to be able to dqtalog afr for safety purposes.
How so i go about it? Afr just shows a fixed 17.7afr in my datalog

In crome go to editor setting -> tuner tab -> and look at the choices of O2 inputs ie Stock Narrow Band, AEM,.....

Chose the one at applies, if you do not see your O2 setup there then chose the WB or Narrow band closes to yours and modify the tables to match yours.

Example: I installed ASPX D1 in an Integra and I chose PLX, entered @ 0v 9.0 afr, and @ 5V 19AFR , the values I get from the manufacture supplied specs.

Worked perfect both the O2 display and my computer were reading the same values.

Keep in mind to ground the O2 setup either to the same ground as the OEM O2 was at the ECU or at the large ECu/Sensor grounds at the engine. (usually by the thermastat)

thank you sir. i tried this but it is still the same.

my afr still goes at 17.3-17.5. thats it.

that's because you're not getting a signal from the wideband. either that or you're just always running super lean.

hi nonsoundflux. i am getting signal from the wideband to my dm6 gauge so i think i do not have a problem with my wideband signal to d14.

then what is the signal? the only reason crome will show a steady 17.7 AFR is is the voltage is above 3.8 which means you're not getting a signal, or it's super lean.

oh. im getting 3.9v. i just assumed that there was. but is it possible that im getting a signal to my wideband gauge properly while not getting a signal to crome?

Fonsicul, try this.

I do all my ecus this way. It doesnt affect how the ecu workes with a stock o2, but it fixes all my datalogging issues.
