Hi all,
Just wanted to post this on here for anyone who was wondering if this would work for calibrating their speedometer for larger tires. I just purchased on and they work perfect. Install the same way as the superlift truspeed or others by intercepting the grey/black wire after the abs module under the hood. hook it up per their calibration one setting and set it with dip switch 4 on, the other 3 off. Then fine tune it with the up or down buttons.
I really just wanted to put this on here because I have been wanting to get my speedo corrected for my 35s and have been contemplating for a month or so about getting a calibration device. I know some people love the truspeed and thats fine, this is for tight wads like me who would rather spend $70 instead of $200. i have had it on for 2 days now and it is perfect with my gps. There has been no needle spikes or anything that I read about on other forums for different vehicles and was told that revision C had corrected that.

 

Do you have a pic of where the ABS module is located.

 

no, but on the gasser its on the drivers side under the air cleaner. you can just catch the grey/black wire in the loom that runs along the drivers fender along the wheel liner.
