VS L67 4WD

[Jackotjk]

I've got a 2000 Rodeo that got a 3.8 with 4l60e which got swapped out for a l67. Running a PCMHacking NVRAM for live tuning goodness.

Looking through the bin the definition has a 4WD flag and ratio settings etc for not messing up gear changes when low range in selected. I found a 4l60e from a 2006 4WD rodeo and am looking for a what pin to use on the ECU to tell it that low range is selected.

Any ideas? It'd be silly to have the option in the bin but not use a pin but stranger things happen...

No one?

What are the chances of modding a bin to enable the flag with say the wideband input as I don't use the wideband unless verifying changes and I can certainly trim fuel off watching the gauge instead of logging

ill have to have a look though what i have but it's obviously something that was put in from the factory but never used, not sure how it operates.

So the 4WD option is to do with the speed sensor, so to keep the speedo accurate in low range you can calibrate it with that ratio. Due to how the code works you enable both those options then use the ratio to adjust it. It doesn't read any inputs it simply is just an offset adjustment function unfortunately. It's likely something GM put in and never finished setting up.
