Tom, you might want to look at some of the older TBI setups that didn't use check engine lights. Very few cars, only one I can think of. The TBI on the old Geo Metros ('89-'91 or so) were very simple, but I'm not sure that would provide the adequate air/fuel mixture for an I-6. I don't know if these are better TBI units, but I know that the Geo Storm and Chevy Beretta 2.0L motors used a very basic TBi setup as well.
