Duramax - Mass Air-Flow Sensor
Troubleshooting & Maintenance
Back about the time the auto makers began using electronic fuel injection, they discovered that for the onboard computer to correctly calculate the fuel/air ratio, they needed to measure the incoming air flow to the engine. Electronic fuel injection not only allowed the engine to run more efficiently and to produce better fuel economy and drive-ability, but MAF sensor data also allowed the computer to help protect the engine if the ratio of fuel to air fell outside of normal. The Duramax diesel also employs a MAF sensor, which is used to measure the grams/second of air entering the engine's intake system.
Performance Turbochargers
for the 6.5L Turbo Diesel
To take the 6.5L Turbo Diesel to the next level of performance, we have to consider using another turbocharger. The factory GM-series of turbochargers are very good at helping the 6.5L diesel produce excellent low to mid-range performance, but the factory turbocharger becomes a hindrance when adding power. The Diesel Page has been promoting aftermarket turbochargers for the 6.5L diesel since the 90's, and we dug deep into the turbocharger theory last year with a comprehensive article that laid out what these engines require in terms of air flow across the RPM range. Analyzing the compressor maps clearly showed that the factory turbos were a limiting factor in producing power, especially at higher engine RPMs. This article is being presented here to show what commonly available turbocharger would make a great alternative.
