Mustang vs 5.0 Thunderbird computer!? January 22, 2011, 06:34:45 PM I've got an 87 Thunderbird engine wiring harness, and a 92 mustang computer I'm trying to use. I'm reading a 5.0 tbird schematic and a 92 mustang schematic, they aren't exactly the sameHad a couple people say I could just simply plug the mustang computer into 87 tbird wiring harness and off I go, but it doesn't seem this is the case...Can anyone confirm that this DOES or DOES NOT work simply by plug & play means? As it looks I'll have to re-pin to different locations, but I'd rather just get a 5.0 Tbird computer... But will that be a problem? Because aren't all 5.0 tbirds automatic, I'm using a standard transmission. And to add to that, my motor is HO, will that interfere with the computers in tbirds that had SO engines?Thanks!Jeff Quote Selected

Mustang vs 5.0 Thunderbird computer!? Reply #6 – January 22, 2011, 08:48:52 PM I have a harness with a mass air conversion because I have the mass air setup I'll be using.. The computer is from a manual transmission car as well.It's literally plug and play? I almost don't believe this because the wiring diagrams, but you're sure?The o2, I only have the one from the turbocoupe. Can that be used?? Or no dice Quote Selected

Mustang vs 5.0 Thunderbird computer!? Reply #9 – January 22, 2011, 08:57:42 PM A manual computer will work just fine in either an automatic or manual car , but not the other way around , thats why I asked I did an HO conversion on my 88 and it was plug and play.......... I promise The V8 cars used 2 O2 sensors one on each side , I dont know if the 4cyl one that you have is the same and you can reuse it and another one or if you need 2 new ones* It was brought to my attention that my first sentence in this post is not 100% correct ... see subsequent posts for more info * I apologize for my mistake however I stand behind the rest of the post :) Quote Selected

Mustang vs 5.0 Thunderbird computer!? Reply #13 – January 22, 2011, 11:10:21 PM Not to be a jerk about it Hypo, but with regards to ECM's, it's the other way around. You can use an ECM from an auto tranny car in a manual tranny car, but you can't use an ECM out of a manual tranny car in an auto tranny car. The ECM for auto tranny cars is programmed to compensate for the convertor-induced drag placed on the engine when the engine is around idle speed. The ECM helps keep the engine from stalling.

If I am incorrect I expect to be corrected ,,,here is part of where I got my info from on Erics site in the link Haystack posted. "It is perfectly acceptable to use a manual transmission computer in an automatic car (but you cannot do the reverse). The timing curve and sensor adjustments are a little more responsive with a manual computer, giving you better throttle response and slightly improved 0-60 times." I will post a few other things that led me to my conclusion shortly .. again I may be wrong , it certainly would not be the first time Quote Selected
