I was responding to you... Jwestpro...
and i think you answered your own questions..
My trial and error tests showed that if i add in the height of the lift to the calibration i can access all three modes and have a stockish ride (i.e. i am not running the bags at too low or too High a psi).. with no lift rods and no calibration changes i can see why you are getting the high center fault. I don't see that changing.
From what i can tell, the controller freaks out because it needs to drop to a -40mm setting in a certain amount of time, this distance is determined via the height sensors and the solenoid valve.. and remember there are not just the 3 height settings for the truck, it actually has 6 or 7 (depending on model)..
Current (ie. factory hard coded), Access, normal, off-road, extended, Highway, and Bump Stop/service mode. the IID tool can only adjust "Normal" - access, normal, and extended are calculated, service mode is set from what i can tell.
I have no idea what your tool can access.
I have not had any issues with the high pressure air line connectors used to extend the corner lines. If you use ones that are not rated for 200psi they will leak, yes.
There are pluses and minuses to all of these aftermarket solutions and also pluses and minuses to just raising it with software.
All i can say is that my truck's setup can use all "normal" height modes with the Full L8 SYA kit.
YMMV
thx for the clarification. I may try them again but with the rods and also adding 51mm to the base setting. I'm also going to do some searching for new air line in bulk.
