I am running '87 5.0 H.O. (speed density) injection in my '73 Bronco on a 289 small block. I have heard that if I swith from a manual trans module to an auto trans module I should be able to pull a data stream for emissions diag. Can anyone confirm this, and if so does anyone know what p/n or code I need to look for. I imagine that a module for a MAF system would not work, but I do not know. Any help would be appreciated, thanks.
