--------------------------------------------------------------------------------

I did an 4cyl to V8 conversion. I have since realized that all ford components are not the same. I have 1992 Mustang body and have a 1990 engine. The car is running a T5 speed. I have a C3W computer which is wrong(it is for an automatic car). I recently discovered that there is a difference in the distributor control module. The control module is for an automatic car as well. I have an A9L computer that I tried to hook up and the car would run, but it would not pull. My questions are listed below. The car runs strong & fast. Hard starting, excess fuel consumption. I am trying to get it to be dependible

Do I have to run a Manual computer in my car? (I know these affects ignition timing)
Do I need to change the ingnition control module for a manual?
Are the pin locations all the same on on A9L computers. I read a post that ford changed the wiring one year.(I.E. fuel pump) Mine is a E9.
What engineering code A9L will work with the 1992 car?

Any advice would be nice thanks.

In the 5.0 tech book it said that you can run an automatic computer on a manual transmission but you can't run a manual computer on an automatic transmission.

You will need to run a computer for a 5- speed and get a control module for a 5speed.And i think you are burning a lot of fuel because you need a bigger pump.If you did not change the pump then you will need a bigger pump you will need one for 5.0 motor. The 4 cyl pump will work but i will not supply the fuel needed for a V8 motor that's way it's burning so much fuel.Keep me posted good luck.

I'll check on the fuel pump and I will see about the computer. I know the timing curve is different in the automatic computer. it is an 18 degree advance
