I am by NO means an expert on this, I am just a few steps ahead of you in the learning curve. The SN95 EEC's do have faster processors than the older computers. The computing strategy is different also. I had a PIH (A9L) in my car when I bought it, and sold it to buy a J4J1. This was the unanimous recommmendation by guys on here who are far more knowledgeable than me about this, such as final5.0 and rootus. There is nothing wrong with them that the twEECer R/T can't help you fix or adjust, I do know that. Good luck and welcome to the wide wide world of self tuning!!
Where is Grady?
There is a ton of timing in the programming (to clean up emissions?) which sucks. I dont think the issue is with the computer itself, just its OEM state of tune (i.e. once TwEECering, the processor works great, etc).
The SN processors are faster and capable of doing more than fox (A9L et al) processors.
Ok, let's find Grady and the other smart folks.

I personally have used a PIH kit (A9L conversion), afm PMS, and an A9L conversion with fox PMS. My car ran the best with the A9L. I liked tuning it with the fax PMS but it became too much of a pain trying to change so many things,,,so i just used the A9L and couldnt be happier. Made the car more responsive and quicker...just my input...
OK, here we go!
First off, I'm gonna use quotes to help me keep my thoughts together and I don't want any of you guys to think I'm making these replies personal.
Everything I'm gonna say is in general terms and not directed to or at ANYBODY even though I'm using some of yalls statements ..........................OK, lol.
Sounds like a good idea
Just more of that internet myth and
IMHO, it all comes from peeps doing the compare thing to the all mighty A9L Fox pcm
and what really is the issue???????????????????????????????
it is nothing more than ...... our pcm's are different
BOO HOO ...... our pcm is more finicky to mods
If that bothers you then go find yourself a rattel trap Fox that has the older pcm and, ...... well, ...... here is the deal........
I'm gonna get on my Soap box big time now so get ready
Nobody has a prob with these kind of statements:
If you wanna make power you need to buy heads
If you wanna make power you need to buy intakes
If you wanna make power you need to buy cams
If you wanna make power you need to buy...you get the idea by now, lol
What is the prob with these statements ??????
1 If you wanna make power you need to buy a tune of some kind
2 If you wanna make power you need to tune your pcm...Fox or our cars
I don't know what to say......but......A tune is no different than any other speed part we bolt on our car to make power and it takes thought and money just like all of those other parts.
Bottom line is that ...........................................
He who puts h/c/i on and thinks not about a tune is Naive and it don't matter if we are talking about a Fox or our cars.
I feel better now ............ I just had to get that stuff off my chest
Now, as I'm climbing down form the box I wanna make it clear that I'm talking about a serious effort NA combo at no less than 300rwhp when I talk about all of this stuff.
I like the fact that our pcms are load based and some say that we have more options due to that fact.
Man O Man, I don't know about anything that I could give a COMPLETE answer to somebody and I SURE don't know anything COMPLETE about that litttle silver box
I like to help if and when I can
I'll reply to the other posts in this thread later tonight but for now..............
the steaks are comming off the grill, lol.

The worst mods for our computers are probably cam, MAF and injectors.
I still think something in our computer system is to blame for our pinging problems. After going through the tune, I think there may have been some kind of discrepency in the MAF flow data. But that's open to arguement and interpretation.

You always crack me up
tweecering
the the best word I've seen yet to describe the self tuning madness
the OEM state of tune
too much spark & too little fuel ...... AKA ......
The perfect road map to the destination of ...... Ping City
You can see as much as 45 degrees of spark or more in certain conditions with the GT file.
You are so right about the hardware not being the issue. The pcm hardware is the same for the GT (sticks or autos), Cobra, & Cobra R

You are kind to say those things and I thank you.
What I really know about is ........................................
things that DON'T work but seem like they should at first thought
The silver bullet, necklace of garlic, or wooden stake is easily obtainable to kill the blood sucking beast of tip in retatd.

Yes Sir ... without a doubt
I really don't want to touch this one lol, cause it has been hashed over and over many times but .........................................................
I've seen some of the Q's you've been asking lately and ........................
It seems to me that your plans are not for a combo with just a few bolt ons.
If you switch to the fox pcm and even if you are lucky enough to not have a single drivability gremlin ...... you will still wonder if you can extract any more power with a Cxxxxxx Txxx.
Can you guess the missing words
Why go to the trouble of a switch out and then have the dad gum thing tuned when you could have just tuned the original pcm
Even though this is not my thread, I don't think anybody would see your Q as a hijack cause the the Q is relevant to our discussion.

First of all, thanks for the change to not using all caps in your replies
You bring up some very good points.
IMHO, the fox pcm retrofit is not wrong in every case.
Where I have a complaint about that method is you see peeps trying to make it appear that the A9L pcm is great and the newer pcm is junk.
Here is where I will say it and won't back down from saying it ...................
A Pro Tuner who knows his stuff about tuning Stangs can make a Fox or 94-95 fly and the original pcm thats in each car don't mean squat to him either. He will use different methods to tune each car but the outcome will be the same and that is both cars will have good drivability and make great power.
Lets face it guys, our cars are only a two year run and the fox has been out there forever. It is natural for peeps to be more familiar with the older Stangs.
Over the years I've seen peeps from many various sites post about some guy saying 94-95's can't be tuned and yada, yada, yada. If you run into one of those kind of guys or places ...... be afraid ...... be very afraid, lol.
As for your experience with using the A9L ...... If you were familiar with the Fox strategy then I don't blame you one bit for wanting to stick with what you knew.

I bought my tweecer a year or so ago and I'm still figuring it out. I got the basics down, but from there it's all a matter of trial and error. Just be careful with it, and make small adjustments at a time. Don't do what I do and test the waters by changing values from one extreme to the other to correlate it's function.
I read up on our computer and the tune for a few months before I bought the thing which helped a lot.
Grady said hit on what I hate about the stock tune, too much timing and not enough gas. I think our tune was a fine example of over the wall engineering at Ford. But that's only speculation.
