75 Dually Project - 22s and stylin

Need some help guys. I started the calibration this evening on the Accuair and it started it just fine, but 30 seconds into the calibration I got a warning that said " Ride height sensor travel warning" So I went to the trouble shooting at the back of the setup manual and it said that the sensor needs to be remounted to a point in the suspension with more travel. I measured everything several times and I have both the front and the rear moving through aprox. 2.5" of travel. So I put the linkage arms to the 2"-3" hole in the arm following the instructions. Have any of you run into this before? If so what did you do to fix it? Any other ideas on what I should be looking for?

Let me know!

I don't have accuair or used their system but doing some reading online the only thing that I would ask is if you have your sensor arms adjusted to be centered in their arc when your suspension is in the center of its motion arc. Only a wild guess!

If it is pointing to a specific sensor try and swap that sensor with another corner. If all else I have heard their customer support is very good.

Thanks so much for looking into that! Yes my arms are in the middle of the suspension movement on both the front and the rear. I will check the specific sensors, and will try swapping if it comes down to that. Thanks again for the suggestions.

dont have any answers for ya but glad you keep getting to do all the hard work for me lol...sorry had to say it again lmao

If your friends ain't messin with ya they don't like ya! LOL!!!

So I went out and bought a 1st generation iPad today (because the guys at Accuair have not released the Android version yet!!!), it was a super cheap deal, installed the Accuair app, and I can raise and lower the truck and work the individual bags up and down, but the system says the sensor(s) are not giving off the correct signal. So the screen says to check the green wire at each sensor to make sure that it is giving off the right voltage. It says that it should be within 1 volt from top of the stroke to the bottom. So I guess I am going to do each corner and see if I can find the issue.

One thing I can tell you is that the York is running perfectly. It is quiet, and I don't have to hear those stupid electric pumps going off all the time. For what you would spend on one good electric pump you could have a York. Just sayin'...

I forgot to mention that your build is going awesome! I am very glad for the multiple build threads that are on here for the squarebodys. I just picked up an 88 R30 crew dually and plan to start a build on it once I get it registered and title transfered.

Hopefully you get your sensors figured out, I have the accuair manifold and will be picking up the switchspeed unit for my toyota but might go with the full eLevel on the dually.


Did you get your York used or did you get a parts store model? I wanna pickup a part store unit but want to make sure I get a 210 and not a smaller model.

Thanks for the kind words! Can't wait to see your build thread on that 88.

I got my York off eBay. It was a reman unit that was to fit a Volvo 240.

Found out what some of my calibration issues were when talking to Accuair tech support. Their tech support is really good by the way.

If you go back in my posts I showed where I am using a 1/2" Airbaggit valve. The valve is fine and works with their system. The issue, or at least part of the issue is this valve is to fast for their ECU. My valve would exhaust to fast for the sensors, thus the ECU would not be able to pick up the rapid change, and so it would throw the "Ride height sensor travel warning". So I had to slow it down. What I did was take the brass muffler off the valve and replace it with a 1/2" ball valve. This way I could fine tune the rate of the air coming out the exhaust side. This worked really well.

So the system could now go through the calibration phase... Well almost... The other issue I ran into is it would not raise the front end very high. Maybe 1"-2", but no more than that. The rear worked fine, but the front was not cooperating. So I again called the tech support line, and they said to raise the tank pressure. The cool thing about the Accuair system is you can change the tank pressure switch with your iPad, iPhone, in cab rocker switch, or Accuair touch pad (or even soon to be Andriod app!!!). The stock pressure is set at 150psi, but you can change it to 175psi or even up to 200psi all with the touch of your finger. Pretty cool in my book! So tonight I will change the setting to 175psi and see if that does the trick, and if not I will move it up to 200psi (hope I don't have to go that high...)

I let you know what happens... Stay tuned...

A major milestone in my project. I got the Accuride finally working right. I had to take the tank up to 200psi for it to run correctly.

I did a video tonight of it going through the 3 different raise and lower modes. My son was in the front seat clowning around. Check it out!

Glad you got it figured out! Now that you figured it out I remember reading a couple years ago about large valves not working as well with accuair because of the speed. I'll be interested to find out how well they work at making live adjustments if you choose to use that feature while driving.

Thanks for the video and again, awesome build!
