How are you getting oil temp readings on the Insight? Is it an add on feature?
GM does not have a sensor/PID for oil temp on the Duramax, so the Edge Insight can not display oil temp as part of the basic things that it does.
However Edge does allow the "option" to add additional sensors, such as EGT, pressure and/or temp for an extra cost. First you have to buy an EAS Starter cable that runs from the display unit in the cab to the engine compartment. Normally you would buy that as a kit with the EGT probe. Cost for the EAS Starter Cable and EGT probe kit is $129. (You can also get just a stand-alone EGT probe for less money, but then you can not add additional sensors. You can also buy the EAS Starter cable by itself.)
You can avoid the EGT probe if you want, but normally you would piggy back any temp sensor on to the EAS Starter Cable that came with the EGT probe kit. To do that, you then need to purchase an Edge EAS Universal Sensor Input Cable. This costs $149 and attaches to the EAS Starter cable under the hood. It has two leads that allow you to connect up to two sensors. You can then purchase Edge sensors or use your own. The Edge Temp sensor runs $39 and you still have one lead left for an additional sensor connection. If you want to add a third or fourth sensor, then you need to buy an additional EAS Universal Sensor Input Cable for another $149.
Once you have all the hardware, then you need to set it up using the Edge MyStyle software program running on your PC. Basically this maps the raw sensor values (voltage or resistance) to the temp or pressure values that are displayed on the screen. You can choose predefined tables for Edge brand sensors or you can create your own custom tables for non Edge sensors. There is very little to do for the Edge EGT probe, and it is not difficult for the other sensors. According to Edge, most sensors from other vendors come with mapping tables in their documentation.
It sounds more complicated than it is. The downside as mentioned earlier is that it gets on the pricey side.
So, here is a typical setup:
- Edge Insight CTS Touchscreen Monitor $399
- Edge EAS Starter Cable and EGT Probe (98603) $129
- Edge EAS Universal Sensor Input Cable (98605) $149
- Edge Temp Sensor (98608) $39
- Edge Optional Dash Pod Mount (28300) $40
- Edge CTS Adapter for Pod Mount (98003) $10
Total before any discounts is $766
I think Edge has a 15% promotion going on right now till the end of October (check first!) and some vendors may give forum members an addtional 10% (doesn't hurt to ask).
Note: The Edge website product page for the Insight and LLY engine shows Oil Temp as a supported parameter. This is in ERROR. I mentioned it to them in August and about a week ago, but as of this AM, it has not been corrected. I wish there were a PID for oil temp, it would have saved me some bucks. They did not include Oil Temp as a PID for the other Duramax engines.
