Wideband O2 datalog $A1 tunerpro v5

[LZeppelin513]

I would like to try some tuning with $A1 in tunerpro v5 but would like to have wideband datalogging capability.

my wideband is going through pin F14 in the 7730 ecm

I went to the ADX editor added new item
-unique id: 70
-packet offset: 0x27 39
-conversion equation: X * 0.03921568 + 10

I am not sure if any of that is correct, I just used the same information from Robertisaar's nast1 code. I know the conversion equation is right because he figured it out for my plx wideband.

any ideas?
thanks

I thought it was byte 33, that's the pin i used to log a 2 bar MAP that was monitoring crank case pressure. That was normal $A1 though, not sure if Robert changed something in his.

equation looks right though.

i rearranged, removed from, added to, etc to the entire datastream.... so there's a pretty good chance that it's not where it would have been.

7730: F14 is the equivalent to 7727: C21.

C21 is normally used for A/C pressure(originally byte 33, if using TP V5, "offset 32")

i left A/C pressure in the stream, but it was moved to byte 40(offset 39 in TP V5), so you technically don't have to create a new item, just rename A/C Pressure to Wideband AFR and change the equation and range and it should work correctly.

if you're using normal A1, just ignore the new location and you should be set.

Thanks very much it works perfectly!
