WANT TO TUNE MY CAR CAR MYSELF...NEED ADVICE

[Gearhead91]

I have an 02 GT 5 spd. I have all the usual bolt ons (headers, x-pipe, catback, pulleys, CAI, intake elbow, TB, shifter) In the future I want to do heads and cams.

What I wanted to do is get a wideband air-fuel gauge (digital) mounted in the car and tune my car myself. I know PRO-M makes devices to control the MAF to control air/fuel and Steeda makes timing adjusters. Does this sound like a good way to tune? My main concerns are A/F being OK and bumping timing. Is a chip really nessesary? I was also looking into hand-tuners. I really like the SCT. If I got this instead, would I need the TA and A/f adjuster? Which is the better route to go? (chip / hand-tuner or separate devices like TA's and such) I just like having the ability to adjust everything on my car myself.

Does anyone know if there is other reasonably priced tuning software for laptops that can be used by end users.

I just ned some input! Thanks

The way I see it, you have two options:

1 - SCT Racers package which is big bucks but will get the job done.

2 - SCT Programmer with LM-1 Wide Band and email cable. This would allow you to data log your a/f, email the data to SCT, and they can email back a tune to you which you can check again with the LM-1.

This would be cumbersome, but affective.

With the software, chip and burner, $795.00
Check out ModularDepot's pre-order forum that will answer a lot of questions for you: http://forums.modulardepot.com/forumdisplay.php?s=&forumid=31
There's also Tweecer -->http://www.tweecer.com/index.htm
The advantage with SCT, as I see it, is the vast network of users who can share their knowledge, lessons, tunes, advice, etc. Also, if you purchase thru Modular Depot, you gain access to their SuperChips Custom Tuning Support Center.
But, as GoHoTo said, you'll also need a good A/F ratio device like the Innovate Motorsport's LM-1. -->http://www.innovatemotorsports.com/
(This is also sold thru Modular Depot.)
Best of Luck!

With the SCT PRP, you will need a separate datalogger (SCT Raptor is about $450 -- very fast, sophisticated but easy to use, CarCode/OBD-II is about $120 -- nice features, not super fast, but inexpensive, and there are others). So, if you want to "do it all", you will need tuning software, a datalogger, and a wide-band O2 meter, and a computer to put all the info together.

Tweecer and AutoTap are other tuning/datalogging packages that are available. I am sure there are others but these are the ones that I have read a little about.

FWIW, I have the SCT PRP, their handheld PCM flasher, and the CarCode OBD-II datalogger. Just getting started.

Hope this helps.
