PCM Upgrade...
Hi guys a have a simple question.
My truck F150 1991 has the EECIV computer, I want make a lot of changes since I'm going to built a totally new and strong engine, but I don't have any experience on computers.
Someone told me the computer used on 1996 trucks can be flashed and totally reprogramed...
Is that true? EECIV just can be chipped?
Any help will be appreciated.

The ECM change would be nice if you plan on a lot of mods. Ford makes a mass air conversion kit, and there are a few aftermarket PCMs. If your just changing cam and heads with a few other bolt-ons, you could try a chip or even better, get a dyno tune. There is a way to mod the EEC-IV PCM to be able to reflash it, I think it is a slight hardware change and swapping the stock prom for an eeprom.
