Howdy. I have 2002 LX470 that I drive in the "High" AHC setting as I have oversized tires and want the "free" lift. I'll be adding front diff drop soon to reduce wear on CV.
I recently got Techstream working and noticed my pressures were way high for the front, 10.9 in the High setting, I don't recall the Neutral setting. I cranked my torsion bars clockwise six full rotations and brought the pressure down to 8.8 in High setting. I checked the pressure at "Neutral" and it's reading 6.5. As I understand it from a post I previously read, the AHC control is balanced when the torsion bars take around 60% of the spring load, which is supposedly 6.7-6.9 reading in Neutral from the front.
My question is, should I be "balancing" this system to have the correct pressure for "Neutral" if I'm running it in "High" mode? ...or would I want to shoot for those numbers of 6.7-6.9 in High mode? ...or maybe 8.8 in High Mode is actually fine since the numbers in Neutral are close to what is recommended?
