mass air flow computer

im not sure if there has been a thread for this or not . anyway, I was wondering if anyone knows if a computer out of a 90 cougar with a 5.0 would work for my 87 5.0 for use in a mass air flow conversion.i m not sure what the number on the computer is . i just saw a few of them in a junk yard today . any info would be greatly appreciated

do your research, make sure the computer numbers match up. most likely, they won't.

well i thought that this was a place to help each other out with questions . so i thought if someone might know it would save me a bunch of time in searching for all the possible numbers. so if you dont know the answer to my question ,Stangnut,then why the hell did you reply .

well, if you would think about what i wrote, you wouldn't be all mad. i said, most likely the numbers won't match up. i said this because i know that they altered the computers from year to year, but i dont' know anything about cougar computers or how they relate to mustang computers. if i were you i'd buy a service manual for your car and compare it to that for your potential donor car. you'll be able to find the specific numbers you're looking for. unless, of course, somebody on here happens to know exactly what you need, which is unlikely.

hey look man reguardless what you said i shouldnt have been like that . i apologize . I was pissed off cause someone busted my window today. thats why i was at the junkyard in the first place. i took my frustrations out on you . just cant stand people who wont let you have something nice .sorry . maybe i ll buy a cougar manual to cross the #'s.

The computer you want is an A9L. Typically found in '89-93 5.0 Mustangs. Check junkyards and E-bay for the best deals...

i have seen that A9L on ebay quite a few times thanks.by the way does auto or 5 spd make a diff?

Yes, I believe it has to do with idle control but I could be wrong. The A9L is the manual computer and the A9P is the auto computer. However oddball computers were used now and then and the Cobra computers are different too.

Yeah, but Cobra comp's were also designed for 24 lb injectors, if you wanna keep it cheap, A9L/A9P depending on tranny..

jeez... everyone has been so touchy lately. 3 out of the past 5 threads have lead to a rediculous agrument about almost nothing. lets all take a deeeeep breath and count to ten. hah we are all here for the same reason, so just, take it easy :biggrin:

have a great day

thats the thing i plan on going to 24lb with a 70 mm mass air just want sure if it would be cheaper to buy it all separate or just get the kit. of course i d feel better about a new computer vs an old one but my head might not feel better when my wife beats on it for spending 650.00 on the kit i found

jegs has the same kit with 70mm mass air meter, 24lb injectors,and matching computer for $545.99 its not a whole lot less but every penny counts on a tight budget. (aka wife) i have the same problem with the g/f...

no thats not bad i know summit had a kit but was for stock 19lb but it didnt come with new injectors of course. thanks alot i ll give them a call

I checked with jegs but it seems that this more of an upgrade kit than a conversion kit .they are telling me i need to convert it first then go with the larger injectors and maf. maybe i'll just buy a new computer and find the instructions online somewhere for the conversion.

The problem you will run into with a Cobra computer is when you do swap either MAF's or injectors in the future, it creates complications, because the MAF will have to be cal'ed for the Cobra comp.

I say get a Pro-M MAF and rip the harness and computer out of a JY.

now if i get the conversion kit which would come with the sensor for 19 lb injectors and mass air computer. Will i have any computer issues when i go to the larger sensor and injectors? :banghead:

As long as you have an A9L or A9P you can get bigger MAF's and bigger injectors and it will run just fine, as long as the MAF cal and injector size match.

The hell with it all, just throw the injection in the trash and carb it! LOL

LMAO yeah right sometimes that sounds easier. anyway thanks for all the input and advice
