I had another post on my 96 f250 with factory MAF that went through a manual swap and no longer runs right. After the 4th trip back from the tuner, the truck still acts up. I'm now thinking that the truck is never going to run perfect on its current ecu. I either have to locate a factory MAF 460 manual ecu which I have no idea what the code for that is. Does anyone know if there is a mustang ecu that will plug into my harness? I know a popular thing with the speed density system is to use the mustang computer for a MAF conversion. Any help is greatly appreciated. Thanks
