Gauges will save you money. Acquisition of a gauge like an Edge Insight CTS2, Edge Insight CTS, Edge Insight CS, or ScanGauge II (note that the ScanGauge doesn't support add-ons like the ability to monitor exhaust gas temperatures or like the ability to prevent engine shutoff until exhaust gases drop below 400 degrees (to save your turbo from frying), but does allow the entry of custom Program ID's [PIDs] that allow you to monitor everything that the engine computer knows about). These items are also available for sale through our intake form and can be shipped out with your repaired FICM! All of these gauges can monitor oil temp, coolant temp, FICM output voltage, battery voltage, ICP's, IPR duty cycles, and a myriad of other handy things.
