i want to put efi on my 351w and plan on using the A9L computer instead of aftermarket stuff. has anybody done this or is there a website that has some kind of directions. thank you for your help

 

Hi Chris, welcome to Mustang Forums!

There are a few people around here that have done an EFI swap to their classic Mustangs. I just did a quick search for "EFI" and came up with 262 records. You might want to look up JamesW. He should be able to help you out also.

Good luck!

 

Post more spesific questions....Yes some of us have done it, as for using the ECU on a 351W no problem. The ECU will adjust for the displacement difference. Is it a direct swap from a 302 to 351W or is this a new setup? Is the donar motor out of a truck or a car? more info please....

 

My recommendation is to go to a salvage yard/pick 'n pull and pull all the equiment off of an existing efi 351.

 

it is a motor out of an 80s bronco and im still looking around for computer and harness. two things i wanted to know was whats the difference between the a9l and the a9s? and is there any programing that i will have to do once i get everything

 

One is for an auto and one is for a manual trans -Jon

 

did the 302 and 351 use the same ecu ?

 

the main computer people look for to use in swaps are the a9l(manual cars) and the a9p (auto cars) you can use the auto computer in a manual car but not the manual puter in an auto. i personally run a auto computer with my 5sp in my 91 gt vert
