If u are going to use a obd1 jumper harness and a p28 ecu chipped, what exactly does that eliminate? I know it would eliminate the knock sensor. But what else would it eliminate? Will it eliminate the evap sensor to and a bunch of other emissions stuff?

 

some but not all since they all pretty much had the emissions stuff to deal with.

do a search and u might be able to find more info.....check archives too
