Which ECU to use?

A friend of mine is going to give me what he has from his 89 mustang to convert my 1966 to EFI. I would like to get a mass airflow computer. Which ones are good and what price am I looking at?

Also should I use his harness or go with the painless wiring?

Will get Pictures up when I get started.

I Believe if its an 89 ecm its mass air
you wanna get one for a stick car regardless ,they're better for performance

Re: Which ECU to use?

it wont matter if it's a stick car or not in that era of pcm's. those cars used non-electric aod tranmissions in autos.. u wont feel a difference trust me.

i would advise buying a 92-93 pcm because intel upgraded to a slightly faster processor (yes, intel made the processors back then) back then. the computer will adjust to the mass air meter and other changes faster with those pcm's.

any stang or lincoln mark 8 computer from 89-93 will do just fine, as well as 5.0 tbirds and cougars up to 93

if u wanna get technical... its actualy the 89 a9l that does the most timing advance.... the backed it off a tiny bit at the factory after that. but trust me, the later pcm's got a faster processor... which means alot in overall drivabilty if u got a cam and othe mods.

an '89 a9l is great for stock to real mild... all the advance in the world doesnt mean shyte though if the pcm cant keep up with the cam and mass air meter...

btw, did u get my pm?
