[Diy_efi] Re: are uC requirements really that high?

[William Shurvinton]

Go the GMecm part of the diyefi website. and you will find most of the stuff
there. If your GM unit is early 90's chances are you can learn how to
reprogram that rather than replace it. You have to do some reading to find
out all you want, but in my mind that is a good thing.
