    I've never been a stranger to the forums as they always come in handy but just decided to join. I'm Kevin :wavey and Mustangs have always been in my family as my father owning over 40 in his lifetime mostly between 64-69 and his last being the 1994 cobra official indy pace car. I've had 3...

    I want to learn more about the a9t computer. Some places I have read it is nothing special. On the other hand I have read alot about it being the SSP mustang (state trooper edition) computer and had a better tune for performance such as a leaner WOT. I bought it to perform a mass air conversion...

    Has anyone used the X-Cal or Livewire tuner on their 94-95 V6? I'd like to know what your experience was and if it was worthwhile... http://www.sctflash.com/PDF/9415Instructions.pdf -- Steve

    I have an '88 5.0 mustang LX, it was running when I got it and it came with a Mass airflow conversion on it.... or so I thought. I did a motor swap and as I was putting the wiring back together I couldn't find out where to splice the cut off MAF wires. After further investigation, I found that...

    I just installed a 94 mustang 5.0 auto computer (U4P0) in my 86 mustang, and it doesn't quite run properly. When cold it will stumble if given more than about 1/4 throttle and when hot it just doesn't appear to have the power it had before. My 86 has a 5-speed. Has anyone else done this swap...
  9. 5.0L Tech
    I'm looking to convert my 93 5.0 to DIS. Mostly to get the distributor out of the way of a custom supercharger setup. I know the EEC IV has the capability to control the DIS spark so I'd like to stay with it. I have a tweecer so I can make the necessary changes. Coil-on-plug would be nice but I...
  10. 5.0L Tech
    Hello All, I have a check engine light that comes one when driving the car for a bit. It doesn't always come on just sometimes. I went to Auto Zone to see if they could read the codes for me but they said they didn't have a machine to do it and that I needed to go to the mechanic. I was...
