2.3L Ford EFI Modifications - Oxygen Sensor
I've been researching some inexpensive ways of improving performance by modifying the electronic fuel injection (EFI) components. Here's the theory behind what works and what may work.
Swap in a larger mass air flow (MAF) sensor - not needed!
The stock MAF for the 2.3L (100 hp) is the same one that is used on the 3.0L (145 hp) engines. It appears that the stock MAF can flow enough air already to support up to 145 hp! The real issue is the air flow through the complete cold air intake system from outside air to the fuel injector body inlet. The available air flow of the stock MAF may explain why we can go to a larger fuel injector!
