Bill -
The two computers are different; the EFI unit also controls the fuel
injection functions in addition to spark control. On the lean burn system,
it is mostly a spark controller. There may be some EFI Computers "in the
mill" from Chrysler - they will try to remanufactue them if they have cores
on hand to rebuild, so try them again. Meanwhile, there are some people here
who do rebuild these - look thru the IML archives to find them. Bob Harris
