Default Tuning Computers? HELP

Hey. My body man had been telling me about computers for mustangs that unleash unused horse power and what not. I found a couple on www.themustangshop.cathat should work for my 1990 5.0 Mustang Lx. I'm just curious if you guys know any more computers that work well? (websites would be awsome) Here are the two I was looking at:
http://www.themustangshop.ca/site/ca...tNumber=OTYwMA==
http://www.themustangshop.ca/site/ca...ber=U0NUQ0hJUA==

Are these or other models hard to use or do they cause any problems? I'm just curious if this would be a good investment or not? Like is there signifigant power increases or is it really not worth the money? If you guys could let me know your opinions on these and other computer and include links that would be great. Thanks for your time.

It really depends on what kind of mods you have done to your car. If you have doneheads cam and intake,added a supercharger, or turbo I would probably look into getting a chip. You can't do the plug and play chip like they sell for diesel trucks and stuff since our cars aren't OBD-II. You would have to buy the SCT chip and take it to a dyno tuner and have them tune it for you on the dyno. Which is pretty spendy sometimes, costed me $800 for the chip and dyno time. Even after having it dyno'd I only picked up 10hp and 10tq. The thing is though, is I was having serious pinging problems in the upper RPM's so I couldn't beat on my car anyways. They took my car in and fixed almost all of the driveability problems on it and straightened out the air to fuel ratio to where it needed to be.

Depends on how heavily modded your stang is, for it to be worth it or not.

If you have a stock mustang you can just bump the base timing for free
and gain as much power as a tuner will give you.

If you have upgraded heads and cam and injectors or boost and such
then yes a tuner will help with drivabilty, idle and top end power

There is a HUGE learning curve on learning how to properly
tune an EFI computer by yourself

Tons of options for tuning
1. take it in to a SCT dealer and have them dyno tune and burn a chip on site for you
2. order a chip from Diablo
3. "piggy-back" tuners that allow you to tap into factory EEC and make changes
www.tweecer.com
http://andersonfordmotorsport.com/pms/pms-50.html
4.Stand alone system that completely replaces factory computer
http://www.megasquirt.info/
http://www.autoanything.com/performa...0A1961502.aspx

www.v8mustang.com carries tweecer and custom chips and diablo chips

Make sure you are looking at products that are for YOUR YEAR of Mustang.

r.barn suggested some good options

Personally, I went with the tweecer.

Another option is the EECTuner...

Let us know what year your car is, and what mods you currently, and plan for the future.

mod it and drop it off to a tuner, there are guys that have spent more time than you can imagine on bin files.

average$500 and takes 4-6 hours, mine took 5 hours.

They modified TPS voltage, fuel curve, adaptive strategy, timing curve and setting, TV pressure on TB, alot of stuff.


2400-redline is Slingshot, best money ive ever spent, and if you need another tune you already have a chip to be reflashed

Just for a different perspective, I'm not trying to start an argument...

SOME professional tuners have a great deal of experience with our EFI systems. Others don't!
I have read countless posts from guys whose cars have been screwed up because the tuner took too many shortcuts...

Fully research the dyno shop you go to...
Ask them about CL vs OL tuning, and if they will tune CL as well.
Some don't [:'(]



OT-
5hrs seems a bit excessive... Did they run into a problem at some point?


Again, just a different point of view on these things.


Ultimately each person has to decide if they are willing to spend the time doing the research required to tune their own car.
It is a very rewarding and you will learn a lot about your car and yourself.
BUT, if you don't have the time/patience/desire to learn, then save yourself the headache and just go to a dyno shop.
