LML SPADE & Smart EGT Control:

Exhaust Gas Temperatures (EGTs) give you an insight as to how much stress you are putting your engine under.  It is the most accurate way to monitor if your current activity is safe for the engine. 

In a factory tuned truck high EGTs would most commonly be a sign of a physical problem like a boost leak.  However, a tuner added to an aggressive driver could result in EGTs beyond the desired limit.  

Most examples of this also include a mismatch of your tune level and truck operation.  Such as the guy towing in his race tune.  

The LML SPADE by DuramaxTuner.com now includes a Smart EGT Control feature.

• Let your tunes manage the EGTs so you can keep your eyes on the road
• Have peace of mind that your truck is safe
• Get the power you need from your truck without sacrificing reliability

How Tractors Measure Exhaust Gas Temperatures

Have you ever noticed that some OEM's do not install an EGT (exhaust gas temperature) probe on the manifold?  Any performance diesel gear head will tell you it's the best place to measure EGT's giving you the  most accurate insight to any immediate stress on the motor.  

Spiking EGT's in the manifold could be a symptom of many different problems including low boost, failing injectors, airflow restriction, EGR failure, etc.  All of these failures signify a lit fuse that ultimately ends in engine failure if left unchecked.  Clearly it's important to monitor EGT's, right!?  

The problem with installing a probe from the manufacturer stand point is the life expectancy of the probe.  Seeing extreme temperatures and still measuring accurately for the life of the service life requires high quality probes (read: expensive).  

Never fear, manufacturers have come a long way in measuring temperatures (and cutting costs).  In fact many feel no real need for a probe favoring a dynamic EGT model instead.
