I just pulled my computer and found that the guy that had it before did have a chip in there that I did not know about. Kind of cool. But I put the TS 6 pos chip in and it is alot better. Also I am wondering if that maybe why my fuel milage was not as good as I hear alot of them being. Anyway, I did not have to take the computer all the was out. You should just beable to take of the black cover and see if there is anything over the circut board. It will fill up the hole that is there if there is a chip in place. Hope this helps.
