Nautilus 2.7 Has Woken Up!!!!

[jbrumley1]

Better than expected results.  2020-year model ... 26K miles with Livernois 93 octane tune, NGK colder plugs.  Very noticeable difference from stock. 

 

Ironically, I sprayed a can of CRC Intake Valve and Turbo Cleaner through the intake.  It threw three SES codes.   So, I sprayed CRC MAF Cleaner on the IAT sensor, which looked a 'little' dirty.  Kept looking for the MAF, however, no luck finding it.  Come to find out, the IAT and MAF sensors are one-in-the-same.   The sensor performs both functions, which I thought was very unusual.

 

After cleaning the afore-mentioned sensor, I cleared the codes with the Livernois tuner and the engine woke up in a very big way.  With only 26K on the vehicle (2.7 Gen 1), thought there would be hardly any carbon buildup.  I was wrong.   Very impressed after spraying the CRC cleaner through the intake and the MAF cleaner across the IAT/MAF sensor wires.   

 

The lack of port injectors must really cause a LOT of carbon buildup on the Gen 1 Ecoboost engines.  This thing is a different animal now.

I believe your assumptions are incorrect.

 

The IAT isn't sensitive to fouling.

 

These days an MAP has taken the place of the MAF - the MAP is way less sensitive to fouling compared to the MAF and its very rare that it requires cleaning.

 

My 2017 2.7L has 123K miles on it and its never needed carbon removal.
