In the early fuel injected trucks the computer metered the velocity of the air being fed into the engine, this system was called SDFI speed density fuel injection.
Later generations used the total volume of air as a baseline for the computer, this system is called MAF mass air flow. As a general rule- not to start any flames- the later MAF system is easier to tune, more accepting of mods.
That's my understanding anyhow, Matt.

Thanks Mattri,
Mass Air Flow I heard of, Not up to the abbreviations I guess.
Old days had mechanical blowers and chargers for power ,guess the computer stuff loses me.

Glad to know I am not alone in the "old school " part.
That is exactly what I am trying to do.
My 2.3 rebuild block is from an 88 mustang, (best I can info find so far) It was rebuilt with no intention of computer stuff, just like old school motors. It is carb'd and I want to put it in my 90 ranger so I am trying to find out how to get rid of the computer or just kill it so it won't interfere with lights, gauges, and stuff I still need.

Our '90 ranger is MAF.

The MAF system is very adaptable to performance upgrades, you literally just add parts and let the computer learn how much fuel needs to be added to compensate for additinal airflow. Of course there are limits, if you do enough to the motor to exceed the fuel supply requirements of the stock injectors or pump then a some additional work is required. In this case you could employ a tuner, or a MAF meter that is scaled to larger injectors with a custom sampling tube, the Mustang guys have been using this trick for years and it works pretty good as long as the jump in injector size isn't too large.
