Why did VL400 use x/10 for all the wideband equations in 12P

Yea that's the go. I did find the specs for the wideband but it is supposed to be accurate between 0.5 volts to 4,5 volts and outside that it says sensor error so I guess it's as you say tweaking the only dilemma is the Chinese wideband. Is that accurate? Anyway I have a LM2 I can use with a genuine Bosch sensor to do a comparison. Hopefully my new eprom reader will arrive soon and I can get back to making bin changes.

the challenge is there are only 2 reference points, so you need to draw straight through them to figure out what to put at 0v and 5v so that a straight line would cross the vendor supplied 0.5 and 4.5 volts and then it should be accurate at any AFR within its range. And that is what we were talking about above.

I do understand that and going off the chart for that wideband I could see that every 0.5volt was linear with a change of 1.19 afr so I just added that to each end to equate to 0-5 so I will start there and see what reading I get.

just on the ADX .... you can change the high and low values, that only changes what numbers you see on the monitor screen ... but thats purely display, as long as you dont fuck with the equation it should be fine.

i normally make the wideband and the target afr have the same values, then when you plot them together on the same monitor window you can easily see if the wideband is following the target accurately or not.
