Logged Wideband input for 95-95 Vin 1 with TunerProRT
This is in addition to the thread I created here..
http://www.bonnevilleclub.com/forum/...ic.php?t=66666
I am using a 94-95 Bonneville OBD1 PCM #16183247 (with a 2000 L67)
Well I got my innovate LC-1 Installed and hooked up. The Wideband is a 0-5v output. Well it turns out that I disabled my EGR and that just so happens to be... You guessed it, a 5v input. Well I gave it a shot.
I used the ALDL byte value 35 and pinned it into the pcm at BF12. The wideband is set from 7.35-22.39 on the 0-5v scale.
The equation I used was X*0.058980 + 7.35
I haven't logged yet with the XP cam so I wanted to check some things out before I really revved the hell out of it. As you can see I'm still very rich.
I just wanted to share.

So are you saying that you are able to log the wideband using the disabled EGR circuit?
This I'm guessing since most pre OBD2 tuning software dosen't have a wideband input?

95nsSTA, thats exactly what i'm doing. Rather than using the input on the PCM for the EGR valve, I'm using it as a wideband input. I then recalculated the formula to read the AFR instead of EGR position.
I didn't have any other way to plot the AFR against the RPM, timing, TPS, etc. This offered me a solution. A wideband is pretty much useless if you can't plot it against the other vitals. Since I only have 1 serial input on my laptop, this was a way to do what I needed.
I'm not sure if there are many people scanning/tuning 94-95 cars but this might be helpful to someone.
