I am looking into monitoring my egt.
This may be a model specific question but is EGT a parameter monitored by the ECU? If so, where is the probe, is it the O2 sensor? And, where can I get the software and cable to plug into my car?
If the above is not an option I would like to buy an EGT gauge. Any suggestions? Any installation sugggestions?
Some cars do have EGT as a feature, for instance the 2009 Jeep Wrangler comes with it. However, for the majority of vehicles out there, the answer is no. You will have to purchase one and install it. They are not too difficult to do yourself. It requires drilling a hole in the exhaust header for the sensor. I don't have a lot of experience with different brands as I bought mine off of e-bay. I have a single sensor version, but you can get them with a sensor for every cylinder. To me that would be overkill as all you are looking for is an average rise in engine temp.Quote:

Thanks, Which type of gauge is better, analog or digital?
You can go both ways, generally a digital gauge is more accurate but also a lil more expensive (depending on brand)Quote:

If you are going to hook it up to a gauge then you will probably need to get an aftermarket EGT probe, install it in the headers, the closer to the heads the better. Autometer makes the best gauges, they have an EGT gauge and probe you can get for a few hundred dollars.Quote:

This will also probably be cheaper than an EGT and probe, and will give you readouts over a number of sensors.
Also find out the location of the stock EGT probe (if you have one) to determine the accuracy of the reading, the further back in the exhaust it is the less accurate and more delayed the readout will be.
