Ls1 ecu's interchangable?

Will my 2001 SS ecu work in my buddies '98 formula? I know that it would have to be totally retuned if it would work because of the differences in injectors, cam and heads. I have tried to do a seach on this subject this morning but for some reason the search is not working for me. Thanks in advance!!

no, 98s need 98 PCMs unless you rewire everything and replace a few sensors
99-02 PCMs are interchangeable
