89 or 95 EEC w/tweecer?

The cost of switching to the fox puter is not cheap and at the end of the swap you have what? Another stock computer. If your going to be using a tweecer the 94/95 puters are easier to work with from what I have read. My 2 cents is stay with the puter you have and use the tweecer to tune it.

i agree with wyt. with a tweecer you can change everything you need. the tweecer is the best thing i have bought for my car.

here's where their forums are located:

http://tweecer.oplnk.net/

you can ask on there who has a 1995 with a 331 and see how it is working for them.

have a 95 that's getting a new 331 w/way better breathing: intake, heads, long-tubes, x-pipe. it's been suggested that i ought to use an 89 processor because the program's more aggressive.

Before all of the self tune interfaces came out that was one of the few options avaiable to tune 94-95 Stangs.

Now that other options exist to tune our cars like Tweecer and such the older pcm retrofit just doesn't offer what the newer technology does.

There is way more to this topic than what you have heard.

plan to use a tweecer, of course you can get an 89 program...any opinions on whether i should tweec the 95 or swap for the 89?

Another thing that you prob heard is the Cobra pcm is really bad.

I'm gonna suggest that not only do you stay with your original pcm but at some point during your mods you very well might benefit from moving to the Cobra cal file. Many others including myself use it with very good results.

i believe the parameters are all the same, so once i'm tweecing, shouldn't make any difference. any comments, suggestions, advice welcome.

Well some of the stuff is similar but for the most basic focus of each pcm it goes like this ...... fox is rpm based and 94-95 is load based.

Bottom Line ...... Just get a Tweecer for your car and use your original pcm to get started.

btw ...... Do like BlackVert said. Go to the Tweecer site and make sure I'm not just another one of those guys that keeps spreading outdated info we talked about above.

Good Luck to you ...... Have fun with your Tweecer!

I don't want to start a PIH vs tweecer pissing match but I run the PIH conversion and am very happy with it. Great put it in and forget about it performace mod.
