Getting A/F to display in the DISPLAY box instead of volts

I'm having an issue with getting it to show me the actual a/f rathern than volts in the display box where you xan see rpm, ait, etc..
Can someone help me out to get it to display a/f rather than volts.

I tried the drop down, but it will not allow me to see anything but volts as an option.

Look for the sensor called 'AF', which you can display as air/fuel ratio or lambda.

In what range does the stock 02 read in AFR?

Post by **Hondata** » Mon Jun 19, 2006 1:01 am

Around 11.3:1 to 20:1

So if it can read a range that wide, why cant I use the stocker as my AFR reading? I am currently non-turbo for the simple fact of getting familiar with the S300 before I start tuning it Turbo, I will have an experienced tuner with me just in case I start to srew something up. My AFR's now under WOT non-turbo above 6k are between 13.0-13.5 which is definately in range of what you posted above.

you cannot use a wideband input as the narrowband signal because it uses the wrong voltage and the corrections it makes are all wrong. I recommend using the PLX wideband as it has both wideband and narrowband outputs that work at the same time so you can use the narrowbinad input to feed to the o2 input othe ecu and stay in closed loop and then use the wideband output to go to the ELD input on the ecu so that you can view and datalog the wideband readings.

thanks Spunk, that answered my question.
I was hoping i could use the wideband for that if nothign else for logging. I guess I'm going to have to re-install the narrow one and wire the wide band in to a differnet input as recommended.
what is the ELD? (sorry My brain is fried today from work.)

So jsut to re-confirm.
shoudl i install the stocker and run it normally, and then run the wideband output to the ELD? (once I figure out the connection for it)

ok really dumb question.
what does eld stand for?

Thanks man!

Hey by the way, How's those adapters I told doug about working out? I've done some more digging and siscovered that company that makes then I told him about can make the ecu connector in a 90* angle. I wish I had known this because I had to cut a big notch in my kick board to deal withthe calbe sticking out, the 90* one we installed in my friend's car worked perfectly. So woudl ya mind letting? Doug know that info so when and if he does order some they will fit better for people?

jsut some info to pass along and again,
thanks man!
