I do not know if I am on to something, but I thought I would share. I am in the process of building a winch bumper for my newly purchased winch (thanks David). In doing this from scratch, there is allot of step by step design that we are going thru. So the first thing to be mounted was a 54" section of 6" channel iron that is tapered back on the ends.

Since this was my stopping point yesterday, I "rattle canned it black" and drove her home with a smile. While smiling and driving, I took the onramp with a speed that has always set off my ESP; only that this time it did not come on. I thought it was a fluke until I tried it again today and took it even faster with no problems.

So, I am toggling the 3 possible things that I could have done to alleviate this issue.

First, we did disconnect the battery when messing with the bumper. It is possible that the computer (ESP) recalibrated itself.

Secondly it could be the bumper's weight as it does weigh more than the stock one. This could make it more stable on the pavement.

And the third one (which I am leaning towards) is that the 2 frame rails are mounted together by solid iron. This would eliminate the body twist when going into a turn that may cause the ESP to alarm.

I did turn if off and back on to make sure it lit up, and it did. Previously, mine never go off even after the lift; but only after I added my 33" KM2s. I will continue to try and set it off and report if I conclude anything different. At the very least, it is less sensitive now.

 

I did successfully set it off today. However I did have to work much harder to do it.

I would hope this did not reduce the amt of flex, if so, over time, it may break as the rest of the vehicle is working against it. Just a thought.
