Just as the title says, I got my wheel centered according to the AEV Procal tuner and it is still off to the left about 1/16 to 1/8 of a turn. If I turn the steering link until the wheel is actually centered, the traction control will activate on highway on-ramps all the time. What can I do to center the wheel?

Jeep has TeraFlex leveling kit and 33" tires, but wheel was off to the left when stock as well.

 

I believe the procal just tells you where the jeep thinks straight is. Mine is off center after dialing it in with the procal but I don't care since the ESP stopped coming on every time I went around on-ramps.

 

I was very unimpressed with using the procal to center the steering wheel. I don't know if mine is broken or if I'm using it wrong, but I beleive it detects where the center point is for the steering wheel, no matter what the current wheel position is. If you crank the wheels driver, and use the aev, it'll center the steering wheel, with the actual wheels turned. for it to work correctly, your wheels have to actually be straight. which makes it useless, because you have to drive around, let the wheels straighten out, and then correct the steering wheel. the exact same way you would do it anyways. it just saves you from having to get up and look at the steering wheel

 

Isn that the point of the pro cal? Your wheel can be off and to just tell the computer it is straight...? I rather loosen the two bolts adjust it and know it is ACTUALLY straight!

 

It worked perfect for mine. I did it once and the overactive ESP went back to how it was when the jeep was still stock.

 

I just did three lifts with the pro cal. Only one was slightly off and wouldn't center. After further inspection, we found that a bolt was loose underneath. Tightened that bolt, and now it centered perfectly. Maybe that will help.

 

But if I adjust the steering wheel until it is straight when I am driving straight down a road, then the traction control does not work properly (comes on too soon) because the wheel it not centered to the cars traction control. In my case, since my wheel is off to the left when the computer thinks it is straight, if I straighten my wheel then the computer thinks I am constantly turning right. Take a high way on-ramp and the computer thinks I am turning sharper to the right than I am and activates the traction control.

Is there a way to tell the computer a new wheel center maybe?

Edit* My wheel will center and my traction control will center with the Pro Cal. The problem is with the Pro Cal, my wheel is turned to the left when the computer thinks it is centered. I wonder if I could disconnect the steering shaft (as many people do to lube the clunky bushing) and turn it a tooth or two so the steering wheel is actually straight when the Pro Cal thinks it is.....thoughts?

 

No, the procal will turn of the lights to let you know which way to turn the drag link adjustment. You still need to loosen them. You then twist it, and it lights up either the left or the right turn signal to tell you which way to twist. once both lights come on, the steer wheel is now centered. The problem is, the procal only tells you that the steering wheel is centered; it does not indicated if the steering wheel is centered to the wheels being centered. Therefore, you can "center" the steering wheel with the procal, and still have the abs kick in as you're driving because you centered the steering wheel while the wheels were off center.

to use it correctly, you should drive, until you know the wheels (the tires, not the steering wheel) are straight. If using the procal, follow procal instructions. then get out, loosen the two bolts on the draglink, and twist until steering wheel is centered. retighten the bolts. drive again to check to see if the steering wheel is now centered properly with the tires. repeat as needed.

the procal does nothing to confuse the computer. it simply tells you the steering wheel is centered (centered in the cabin, not in any way correlating to the tires)

 

Couldn't have said it any better if wanted to.

 

Oh! Sweet...lol that's what I get for talking out my ass!
