OBD-II Data Set Available on 1998 GMC C/K Series 6.5L Diesel Pickup

Question:

are there sensors or add on kits that you can purchase to monitor EGT, Tranny temp, boost and fuel pressure, Im not sure what will be monitored on my truck being the age. I would like to monitor. 1.Boost 2.EGT 3.Transmission temp 4.Fuel Pressure Can you tell me which of the above would need a sensor and if you can purchase separate senors, and what would the part numbers be. Thanks

Vehicles produced in the U.S. after January 1996 were required to have an OBD-II diagnostic port under the dash. These ports will carry a specific mix of engine performance data depending on what the auto maker chose to include. The specific data available for display on a tuner/monitor will vary between vehicles.

For your 1998 GMC C/K Series Pickup we offer two Edge Performance monitor products that can display this OBD-II data. They are the Edge Insight CTS2 # EP84130 which has a Touch Screen and which can display up to 12 engine parameters and the Edge Insight CS2 # EP84030 which has a standard color display and which can display up to 8 parameters.

I asked my tech contact at Edge about the data set that is likely to be provided to your OBD-II port. He noted that older trucks like yours can have more limited data than newer model years, but that it is likely you will have coolant temp, transmission temp but possibly not exhaust gas temp (EGT).

We offer EGT Sensor kit # EP98620 that works with both of the above monitors. Backup camera kit # EP98201 can be added to the CTS monitor to allow that monitor to serve multiple functions.
