Yah my Nightmare Project is supposed to be controlled by the factory 5.9 ECU. I changed the sensors and harness, still no go. I thought the RH trans were "H" hydraulic control, didn't realize a controller would work for those trans. Probably not horrible on fuel with progressive linkage and those Rochester 2G? are good carbs. And beer keg gas tank and tool box battery box are the icing on the cake.
