Tweecer, AEM, Superchips Custom Tuning, & AFM PMS????

I have been reading articles in the last couple of mustang magazines about different tuning devices. I will be buying one of them when i go with the 351w next spring, but i was wondering if you guys had a opinion on which is best. I know a lot will say tweecer, but i guess im looking for reasons why. Price? Ease of use compared to others? Tried and True?


edit: Well i just went to the AEM website, and it seems that system is like $2400 or somewhere in there. Thats crazy, so i see why thats out of the window. And the superchips seems a little new and doesnt seem to go into as great as depth as the tweecer does.
 
I'm using a JMS custom chip. One of the best mods I've put on my car. Driveability is very close to stock, I gained alot of horsepower and the tune had a flat ~13.2:1 A/F ratio on the dyno. Not too bad for a mail order chip.

They also took away the tip in timing retard, and closed the EGR valve and associated check engine light.

PMS is much easier to use then anything I've seen. I was a Tweecer owner at one time. Just way to overwhelming for me. The PMS uses % tables and yes/no questions.
Vib pretty much hit the nail on the head. If you are only good with computers to a certain extent (like myself), you are going to find yourself getting very confused, very frequently with the Tweecer. I am sorting through this stuff and I still have very little knowledge or know-how about this thing.

Speaking of which, I think I'm going to start another "Help me with my Tweecer because the owner is a jackass and can't figure it out" thread.

I am going to get into the tweecer real soon, seems the stores are out of supply right now though, will check later this week though...

I loked into the PMS and such and the tweecer seemed to be the best bang for the buck, even though the software has a steap learning curve. as the PMS was like 300$ more than the tweecer, and I guess you are paying for the ease of tuning. I just plan on going into the tweecer with alot of reading time (so much so that I am starting to get things mixed up since I cannot work things out on a screen yet) but I think if you go into it with an mindset that you can do it, but you will be very frustrated and take your time you will be fine.

From my reading there is a realy good tool for tweecing called eec analizer, it seems to be very helpfull.

So it realy comes down to what/how much you want. To spend/learn/or not have to deal with.

**edit I wish I could spell :p **
 
i have a tweecer, and like the others, i hear it has a steep learning curve, but this stuff is really interesting to me (i'm a computer programmer) and i really want to understand how the computer is going about its business. plus, since you have so much control over it, once you understand it, you should be able to do anythinng you want with it. also, it has 4 slots for different tunes, so i am going to make a tune to maximize my commute mpg, another one for highway cruising, and a high performance tune for having fun.

now all i have to do is get around to installing the friggin' thing.

It's going to depend upon what level of tuning control you want and the amount of time you are willing to invest in the process. I opted for the AEM as it appears to have the capability to tune/adjust every possible parameter as well as datalog all events. Current full retail is about $1800 but they are generally available for around $800 used or new from a buyer who decided to go a different route.

5years later and the answer is..... :p
 
i just got a tweecer used from corral.net im still having a lil bit of trouble with it as well on the datalogging software called calcon. once i get that issue worked out, i really think its gonna be fun to play with.

the caledit which is where you can go in and make changes to the pcm is really neat and very in depth. I have already changed the timing the correct way through the pcm instead of moving the distributor. I have also removed the tip in retard and turned the egr and evap system off as well. There are several tuning websites out there to help you with learning to use the tweecer system. i really do like it and getting forward to tune my car myself. best part about it is whatever i do to the car or even if i sell the car i can use the tweecer on any ford car or truck. i still need to get a wideband to correctly and accurately maintain what the live a/f ratio is.
