Yeah, I'm just not sure if there's a limit/range that you can zero it to. I saved this uncertainty and the $300+ cost of a Tech2 by buying $3 in stainless threaded rods and resolved it manually.

Well for someone who already had a Tech2, curious if it's been tried and the results.

I would have to hook up the tech2 again to check on it.

Ooooh! Can the Tech2 command X amount of voltage to the shocks to manually set the valving? It'd be awesome to drive around and change it a volt at a time (or in 20% steps) to feel the changes. Then, maybe try half volts/10% steps to see if fine-tuning it that far is noticeable.

I don’t know. I have some shop time later today. I will poke around in the menu.

It can only command on and off and only one at a time. I don’t see a voltage for the dampening. Only a percentage. The only voltage I see is for the position sensors.

Well, that's a little something. Bummer you can't manipulate at least two at a time. If the shocks work off a 0-5V scale, then a percentage is easy enough to use. Still pointless if you can't do both fronts or rears.
Thanks for checking. I'll just have to do my analog thing...

Somewhere there must be documentation telling what the baseline reading should be. Dealers checking to see why some whiner owner is complaining about a stiff ride need to be able to check that. Worn sagging springs would affect the setting I would bet. Unless part of the startup is to check the ride height and running from that as baseline each time you start.

It would be unusual if all 4 position sensors would read the exact same voltage with the truck at rest, as the physical mountings are not that precise. That is where the Tech 2 and the automatic level control (ALC) reset/calibration function comes into play. When you reset the ALC, the exact voltage readings of each sensor are recorded in the control module as the benchmark or baseline. The control module then measures any voltage changes in each sensor from its benchmark voltage, and adjusts as needed, based on those changes.

So you have to do a reset manually to store readings? That suggests that to soften the ride you do the reset with a load so that at lower load levels it allows the vehicle to return to the baseline level more easily.
