MAF conversion and tuning for the Ford 2.3 turbo
Definitions:
load = 1000 * [mass air flow (#/min)] / [engine speed * 2]
Project overview
What is needed?
- MAF meter - OEM Ford preferred and supported on this page.
- MAF sensor connector, relay, wire and the ability to decipher a wiring diagram.
- EEC Tuner, TwEECer, J3 adapter (Stokes, Moates, etc.) and the ability to program to it.
- Wide-band O2 sensor and the ability to data log air-fuel ratio (AFR) and MAF voltage simultaneously.
- Laptop or PC with MS Excel and the ability to group and average data to tune the meter to your application.
If you don't have ALL of the above items, you will find it very difficult to complete a successful conversion.
Parts needed
MAF meter - Ford produced aluminum, 4-wire meter ranging in size from 55mm to 80mm. Ford also produced a copy of the aluminum 4-wire meter in plastic usually found in the 70mm and 80mm size and found connected directly to the air box. The next generation

Modifications
Changes for large injectors - L series
