Hi all,

I was running johnson rods with proud Rhino SYA spacers and purchased and IIDtool. I connected the tool which the rods and SYA's in which set the default settings for the tool (oops, the manual said it can not be changed). Then I pulled the rods out and the car could not go to normal height (hit the stops and go in extended mode).. So then I set the setting in the height control at +19 in the front and +20 in the rear for all three settings. And then I went to calibrate each side (on level ground). Well if I took it to the calibrated settings in the IIDtool App, normal would hit the bump stops and it automatically changed my height settings to +3 in the front and +20 in the rear (DOH). It now drives bouncy and harsh in the front.

What I am trying to achieve by taking the rods out is a lower normal setting for highway and freeway. When I had the rods in, the handling was poor and I was getting rollover warnings on some turns along with some suspension faults. Now I am lost in a IIDtool quagmire and want to reset. Should I put the rods back in and just start with a lower new "normal" height using the tool?

If anyone is using the SYA stops and an IIDtool I would love to see how you calibrated and what height settings you chose?

Thanks in advance

I would ditch the rods. Put the stock rods on. Then with the IIDTool I would set it to the default settings. Then I would go look at the live values for calibration and create whatever height setting I want with a new calibration and save it. I suppose you could use the Guided Calibration too and lower it in real time, you just don't want to go below any calibration limits.

 

It might be a pain but if you are getting rid of the lift rods you might want to get rid of the SYA spacers, put the stock rods in and try and calibrate the system from scratch. Then add back the spacers and try to increase the ride height with the GAP tool. You have gotten the system out of sync and is probably going to take some work to get it back to where you want it to be. You can also try to contact the people at GAP and see what they suggest.

 

Thank you both for your reply. Having some difficulty with the IIDTool as it saved the lifted heights in the CCF and when I try to go with the guided set up, it will not accept as the new measurements are beyond the parameters (150-250). Here is a pic. The left Front seems to be the biggest issue.

 

...is that with the stock rods on, or the lift rods?

 

That is with the lift rods back on. The baselines with them off were over two hundred. I am going to take it to the mechanic to re-calibrate tomorrow morning. Going to see what he can do with either lift rods in or stock rods in. He does not have time this week to remove the SYA's but will get it safe for my week long vacation starting Friday. The spacers were pre-mature as I am running 265/65/R18's. The spare fits under the truck after deflating somewhat. The ride quality lifted was poor and I kept getting stability alerts and some suspension faults. Most likely a calibration issue but I do far more freeway driving to get to offroading/overlanding than I do driving offroad.

 

I'm not sure what you mean by the baselines being over two hundred...you talking about the real-time measurements in mm or the calibration live values? I guess I don't see how the mechanic might be able to calibrate it any more easily or successful than you can with the IIDTool.

What have you actually attempted to do with your GAP tool? Have you walked through the "Guided Calibration" and failed? Nothing you describe above sounds like the Guided Calibration. I'd suggest putting on the original rods and trying that Guided Calibration. Don't worry too much about the live calibration values; they are arbitrary constants.

 

I would just do a manual calibration with the rods off and set all heights to 180. Then after that, do a guided to get the truck level again and back at the heights you want.

 

I appreciate all your help so far (sorry was away for a few days). So I took the car to my mechanic (he could not fix). I put the stock rods back in and we tried to go through a guided calibration. The Front left sensor is failing the calibration. I was looking to do 520 mm in the front and 530 in the rear to accommodate the spacers. The car is running at 470 in the front and 500 in the rear and the air shocks are compressed and bouncing off the bump stops. Here is what the tool is saying

 

You need to set a baseline calibration. All set to 200. Did you do that first?
