Re: Chips N Such
hoorders, your truck has an intirely different engine and computer system. There are no chips for the newer style (OBD-II). Chips are only available for the older series of computers (OBD-I). Now, you can use a programmer, or tuning module. Do a search for "hypertech" or "power programmer" on this forum. There are a few members that have it, but it's been discussed often.
OBD = On Board Diagnostics
Generallly speaking, the OBD-I systems are on TBI equipped trucks. It's a pretty simple minded system. It will tell you there is a problem with the emissions, not left bank or right bank O2 sensor. The OBD-II system has more memory and better programming to identify problems. OBD-II WILL tell you about a left bank or right bank O2 sensor.
