Yes the Mustang computers have a more agressive stock tune than the truck, they also have more "stream lines" for tuning with tweecer than a truck computer.Someone please correct me if I am wrong, but I believe the mustang 5.0 computers have a more aggressive stock tune than a truck computer would have, which is why they are so often utilized, plus they have the J3 port which allows for the Tweecer or QH mods.
I have the air box with the air temp sensor in it with the mass air, getting the harness isn't a problem either the ECU is what I need. If I can run a 5.0 ecu for an electronic tranny then I should be good if I am assuming correctly.Yes the Mustang computers have a more agressive stock tune than the truck, they also have more "stream lines" for tuning with tweecer than a truck computer.
Also even the SD eec's have the J3 port.
Heres my plan:
I want to do a Mass air conversion on my 89. My plan is the get the SD to Mass air harness for RJM, a 5.0 Mustang eec from 88-93 (with auto, w/o computer trans, cause I have AOD), and later a tweecer for more tuning.
**Another thing, If you get a Mass air computer from 94-up you have to move the air temp sensor to the air box.**
