Should I install the EGT probe before or after the turbocharger? I’ve heard before is best, but I saw an EGT mounting hole in an aftermarket exhaust system, and now I’m wondering if I can safely mount it after the turbo charger?
The ONLY correct position for the EGT probe is before the turbo in the exhaust manifold. There are two reasons for this: response time and accuracy. If the probe is mounted far away from the manifold, the lag between when the probe will register an increase in temperature, compared to the reading if the probe was placed in the manifold, can result in misleading EGT numbers. When used in conjunction with the Juice, this is of particular concern since the module needs to be able to de-fuel as quickly as possible to reduce EGTs when needed.
The second reason is accuracy. Putting the probe after the turbo can create inaccurate readings because the exhaust gas will cool as it travels farther away from the manifold. This discrepancy can be as much as 250 degrees, which is far too big a margin of error. Also, depending on the power upgrades you have made, the turbo itself may throw off the accuracy of a post-turbo reading. If the turbo is a restriction, excess heat will build before the turbo as hot exhaust gas backs up, while post-turbo EGT will be much lower - resulting from the reduced exhaust flow which cools even faster than it would in a balanced system. This situation can be particular dangerous because excess heat will quickly build in the motor while temperature readings after the turbo will seem almost too cool.
Remember, your exhaust pipe won’t overheat, but your engine will.
What are EGTs?
EGT stands for exhaust gas temperature, and is the single most important indicator of how a diesel engine is performing. Unlike a gasoline motor, a diesel motor will continue to make power as more fuel is added. As more fuel is added, heat will be generated until the motor just gets too hot and things start to melt. This is a situation to avoid. Exhaust gas temperature is the ideal measurement of how hot the motor is, since temperature fluctuations in the gas are almost instantaneous. You should consider using the Edge Attitude or installing an EGT gauge even if you make no performance upgrades, since EGT is such an important indicator of engine load. This is particularly if you tow.
What level should I tow in with Edge Comp Dodge Performance Module?
The only levels suitable for towing are levels 1 and 2. Only use level 2 if you are towing a light load. Never tow without an EGT gauge or an Attitude monitor. If you want to tow in a higher level, you must make significant engine and transmission upgrades beyond just a chip in order to handle the increase in power. It’s that simple. Even though the Attitude monitors EGT and will automatically de-fuel to prevent excessive EGTs, you should still only tow in level 1.
