Making EAS Height calibration blocks

Tasmanian oak calibration blocks get a big 10/10 for me. Its the only way to set the heights wont bother again wasting time with the guard method (could be the operator rather than the method).

The compressor stopped half way through the process i diagnosed it as the pressure sensor, lucky i had a spare one on hand from a previous valve block rebuild, replaced it and got things back on track.

Set the access, low and standard heights as per the book but increased the Extended height 1 inch plus all round, to take advantage on the gen 3s.

Tried extra two inches all round but found the fronts rose to expose the air bag clamps and Ive heard somewhere not to go above that height.
Also tried an extra two inches on the rears but the height sensors read 166 & 164 so out of range. At 1 inch extra they read 149 each so settled for that. Might try to extend my adjustable height sensors another time to get the two inchs. But reckon I will give it the acid test 1st before I play any more.

Thanks again all for you input.

Why are you concerned about reading out of range?

Hi Dougal,

from what I understand, if the readings went outside the sensor range eg extended height 105-150 for rear this would cause the system to go to a default value. Is that incorrect or is it the way Ive interpreted the information?

I'd try it and see.

In my experience, when the input "bit" number exceeds the range stored in the firmware, the EAS ECU may either throw a fault or default all settings to factory values and you have to start again...

Yep. You get a fault and a reset to the default settings, undoing all your good work. So you have to ensure they're in range. Also ensure they're within 10 of each other left to right.

I did try set the rears to 165 while attached to the eas unlock and it would not let me, it returned to 145. Sounds like not worth trying again.

Thanks Guys.

Sean I had not heard of the within 10 side to side, thats good to know.

Sean have you used the standard heights or gone custom heights, we would have similar setups, particularly as my lift spacers are from your design thank you.

So in that case, you could extend the push-rods to bring it into range as long as you can keep your other settings are also within range.

My settings are what they are. There's no such thing as factory eas settings, only factory heights. Every sensor produces slightly different readings at a set height.

So my settings are dictated by the heights I've used. with an eye on the upper and lower limits of course.

Hammer H - just read yours again. I guess mine ended up pretty much 2" above each of the factory heights. Except I've erred on the lower end if the scale for highway and standard.

I can post heights of you like.
