Programming Chips ???

[JLaser]

I am looking at getting a chip specifically to calibrate my speedo and odometer after changing the tire size. Most of the major brand name models appear to do approximately the same things and cost around the same amount. Does anyone have experience with any specific models (good or bad)?

I've narrowed it down to the Superchips Flashcal F5 for JK ($180) or the AEV ProCal Module ($170). They both have additional functionality that is neat to have, but not really necessary.

Do either give you the ability to use the lockers in 4 wheel high? I would like that option.

That's a good point. The Superchip definitely has that feature. The AEV doesn't mention it, so I suspect it won't...

superchips are generaly updateable as well.
