I'm planning on picking up a 95 Mustang GT engine tomm. to swap into my YJ. Should I should pick up the computer that came off the 95 (i can get it for an extra $50), or should I instead get a computer off a 87-93? I've heard that using an older computer instead of the 95 will work, and be better because the older computers are better all around when doing swaps.. but i'm not sure if this is correct, again i've only heard it once so basically i just need confirmation if anyone has done this/knows if its possible.
Thanks,
Shane

search fawker :flipoff2:

oh and i have no idea, but in deciding you may want to conider emissions testing as to what will get you to pass, if you decide to have that thing tested

I'll second the search newbie:flipoff2:



But I'll also include a link for ya.

All you need to know about the 5.0 swap from the topic of the week discussion in this forum, easily found by searching. (http://www.pirate4x4.com/forum/showthread.php?threadid=45309)

Oh man...
First of all Mike i go to school with you so watch what you say.. i know where you live buddy... and second.. honestly, since you guys are so quick to point me to posts that "apparently" already cover my question... then copy and paste the exact fucking words outta the post in here.. i wana see that shit cause ive read every god damn post on this board about mustangs and NO WHERE is there the answer to my question. So, if someone who doesnt sit around all day and talk shit on this board wants to try and help me out, id appreciate it. And like i said, if you guys can copy and paste a link to a post that answers my question i'll fucking eat my words..

thanks to anyone who can help me out..

when is this newbie bullshit gonna stop? I understand that when fuckers ask stupid questions that obviously have been answered.. then fuck yeah its justified to talk shit.. but come on.. you both know damn well that my question hasnt been answered....

Whoa there buddy, get a sponge and a bucket of water to wash that sand out of your vagina. No I dont know the exact answer to your question but I gave you a link to point you in the right direction. Even if that post didnt answer it, and seeing how you have read every post about mustangs on this board, you should have,
a) figured out who knows their shit so you can pm them with specific questions.
b) found some links in the discussions that will point you to the boards experts refrences.

Despite the crassness of the board, most are more than willing to help when they can, figure out by reading who you would trust and pm them to see if they can help. They didnt get their info from the great beyond, so even if they dont know they can probably give you a refrence in addition to the ones they link. Have you thought about trying a mustang board for answers?

If your looking for everything to be handed to you on a silver platter, your in trouble. Even in one person chimes in with what you want to hear its best to cross check the info before spending money so either way you still have some research to do.

Welcome to the dark side.:flipoff2:








By the way, unless you want to get links to previous related questions when you ask something, its a good idea to state that you have already searched and were unsatisfied with the results. If you had I wouldnt have bothered in the first place and just let this post slip off the front page into obscurity. Have a nice day.

Easy Shane, down boy, didn't realize you'd searched it all already, just givin you a little bit of a hard time. Don't be too offended. ;)

I have no idea why the earlier computer would be better for the swap, since it's the same engine I figure either one would work. I'm not sure when they started doing OBDII testing, might have been 95, so that could be why the earlier computers are better. If that isn't the case, I'd just use the 95 computer. That way you know it's compatible and that it's going to work. Again, I have no clue why an earlier comp would be better for the later engine.

Going to a mustang board was a good suggestion, i didn't think about that.

For $50 I would buy the computer that came with it.
You can do the swap, and make sure everything works, then when the bugs are worked out if you think you need more power, you could go to an 89 computer(I forget the number) or a 93 Cobra computer, those are the computers of choice for those looking for every ounce of performance. Neither are gonna give you that much noticeable performance however, unless you port match the heads, go to 24lb matched injectors, go to a larger throttle body and mass air sensor, add a performance cam, and beef up the ignition a bit. I run about 300hp/350 +ft/lbs, with all of the above and a few other tricks and a 93 cobra computer.

If you swap to another computer later you will still have your stocker as a spare, and $50 for a known reliable, Factory spare is not a bad price.

By the way Im sure I have mentioned all of the above in more than half dozen posts in the past, so quit being so cocky and learn how to search fawkin newbie. :flipoff2:

H8Monday-
I appreciate the info... I had noticed from reading your old posts that you know a lot about Mustangs... the thing is, like the other two, you can sit there and talk shit all you want, but until you show me half a dozen references to old posts where you've talked about a 95 Mustang computer I still call bullshit... I can't believe that even after stating twice that my question has not been answered and simply said "if your gonna give me shit, show me an exact post where it's already been answered" but yet no one has shown me shit, and you still keep talking shit... keep up the good work!

Well Im not the one that needs the info so Im not gonna waist my time searching for you. But trust me we have discussed many many many many times the attributes of different computers.
If you are waiting for a "Hey if anyone named ridicuoluseYJ, has a 95 Mustang engine, and wants to know about computers, this is the end all to beat all info" Post, well that is probably not out there. But all the info you need is there waiting for the taking.
Obviousely Ive done all that I can do here,..so my work is done.
OUT!

1995 should be ok. OBD 2 started in 1996, that's when ford went to the 4.6's in the mustangs.

Thanks Taso.... thats the info I was looking for.

All you wanted to know was if the computer that came in the car stock would work with the engine it was attacthed to?
What a fuckin joke.
And you wonder why we get tired of answering the same ol stupid questions.

Did the short bus just let everyone off at the door to this bbs or what?:flipoff:

The differences in the computers are the older ones use a MAP sensor and the newer ones use mass air flow. I don't think your years are correct though. I seem to remember the Mustangs being MAP from '87-89 only. Could be wrong though. The MAP computer is more forgiving to modifications I believe. I honestly don't remember the details, but I know it's been discussed here. If not in the Jeep forum in the General 4x4 forum.

Like H8Monday said, the info is out there in random bits and pieces. You just have to keep track of all of it as you can and make your own decisions like everybody else.

A good book to anyone considering a Ford swap is "Ford Fuel Injection & Electronic Engine Control" by Charles Probst.

Thats not actually correct, there are differences in different years of the Mass air computers. As stated above, the 89 which is something like an AL9 computer has some of the most aggresive tuning. the 93 Cobra computer is also considered one of the most aggressive of the computers. The AL9 works well with stock configured engines, but still accepts bolt ons and cam changes well. The Cobra computer doesnt come into its own unless you go to the bigger injectors, and the other items I mentioned above as that is what it was designed for.

'86 , '87 and 49 state '88 5.0s used a MAP sensor. If you don't want to mess with an MAF, use one of those. '88 CA only and '89 - '95 used an MAF. The '93-'95 cobra computers all used a larger MAF, and 24lbs injectors, so you will need at least those parts to use a cobra computer. Cobras also used a better intake manifold and a larger throttle body, so you will probably want those if you're going to all the trouble.

Thanks for clearing up my "I thinks" Jeff and Oliver!

The Cobras are aslo cammed differently. They used a shorter durration, higher lift camshaft, and 1.72 rockers. This was done to achieve more low end HP, in cunjunction with the slightly longer and rounder intake plennums. However the same computer used with the shorter, oval stock intake plenum and the B303 cam, creates a very torquey low end combo, with a super strong, instantaneous mid range. The larger, fuel pump, injectors, MAF and TB are needed as stated, a well designed set of headers, and a CID ignition, doesnt hurt either.

just a quickey so all the stated above use the t-5 for a tranny and is the bolt pattern the same as the t-5 for heeps...................ltr

The T5 has been in the 5.0 Mustangs since the early 80s, but has gone through about a half dozen changes since then. the eraly versions being best used as boat anchors, The 93 versions in the Cobras (the World Class, wide ratio), is considered the strongest, but would not make a good off road tranny due to gear ratios( something like a 2.95 1st gear).
I pretty sure the Jeep T5 and the Stang T5 have different bolt patterns and maybe different input splines.

thanks............ltr

I'll have to defer to you here, I have never owned a cobra motor. I will say though that I really like the Crane compu-cam I put in my 5.0. It seems to have more power all across the RPM range, and still idles and runs great.

Actually, I think the bolt pattern on the case is the same, but the input shaft is different. Mustang V8 WC T-5s have either a 3.35 or a 2.95 first gear ratio. 4 cyl Mustang T-5s and Jeep T-5s have something like a 4.03 first gear ratio.

To answer your original question you actually need to decide what wiring harness you want to run? Are you doing the wiring yourself? The (88CA)89-93 harness is the simply way to go and if you want to buy one they can be had relatively cheaply. The 94-95 harness is gonna cost more money unless you can get it with the motor and its gonna be more work to wire it up. The wiring info on the 89-93 motors are everywhere on the web, not so with the 94-95 harness. And avoid the cobra ecu its not worth the effort.
