Okay here goes...

I plan on installing a wideband O2 sensor in the next couple of weeks (along with a boost gauge) for an upcoming turbo project (probably STS). I have a laptop and was wondering the ability to tune with one of the full tuner suites vs. getting the car dyno-tuned. Is this recommended? Basically taking the time to run the car, pull numbers, adjust, again, again. I know this probably isn't the best way but figured its worth the question...

Any recommendations on tuning software...

Full Tuning Suites:
HP Tuners --Tuning and Scanning, Wideband Support via EIO. www.hptuners.com
EFI Live -- Tuning and Scanning, Wideband Support, www.efilive.com
TunerCat -- Tuning
LS1 Edit -- Tuning , limited scanning

im running a supercharger and a wideband O2, and I use Hptuners.
you can do 99% of your tuning that way, just have to be careful on the street.
make sure to get some sort of enhanced IO so you can log the wideband along with all the other data.

To me the dyno is just a tool to see what my end results are...

one thing to keep in mind, a few turbo setups dont put out full boost when on the dyno, compared to the street. something to do with engine load or something.

If you have the time to learn how the PCM and associated sensors work and take time to learn the specific software you will buy then doing your own tuning is one of the best mods you can do. It also allows you to easily change the tune when you keep modding without having to drag it back to the dyno for a tune. IMO tuning yourself is a great thing to learn to do.

I would go with either EFILive or HP Tuners. These 2 are the most advanced out there right now.

430/400 cam only with a street tune...for the most part I think street tuning when possible is one of the better routes.

Get the hp tuners, you wont be sorry ! I paid for 2 dyno tunes and still bought the software, and have made a bynch of changes for the better !

Tuning software is always going to be your best mod...rather then growing out of it it grows with you.

I'll be purchasing EFI Live commercial on monday, I've been researching between the and HP Tuners since january and am ready to make my purchase....

I'll be getting the commercial + wideband from greenlight motorsports.....

how about personal tuning, on a dyno?

That's my preference, but most people don't have that luxury.

I would say final tweeking on the dyno is fine, but its very hard to tune part throttle, shift points & even wot fueling on the dyno since they are loaded differently(for the most part) then when you are on the street.

EFI Live has 3 different licenses
Personal
Commercial
Workshop

Personal and Commercial are almost the same except with commercial you can load different OS's to your PCM....

Workshop is the big badboy for tuning shops with dyno's

I'd only do that with a Mustang dyno that didn't cost an arm and a leg...for now, tuning my car at a classified location will suffice

That only applies to inertia only dynos, not dynos that have computerized load control based off of the vehicles weight and air drag.

True.... I'm spoiled with having access to one

I feel EFILive's package is a wonderful package and does exceptional with its extra features! Not to mention, it doesn't cost any extra when you purchase the commerical version.

with hptuners $649 pro package you get enough credits for your vehicle, a 3 bar tune and still have 4 credits to spare

Buy some software and learn to tune it yourself. You will end up with a much better result than a dyno tune. As said the dyno tune is not going to be that great except for WOT, and even that will not be exactly the same as on the street/track.

Or you can get in on one of my current specials and for just a little more, get unlimited 1/2/3 bar for use on other vehicles in the future, no credits, nothing else to purchase.

This is true my friend when referring to an inertia based dyno. Most good load bearing dynos on the market today can simulate very specific road conditions remarkably well. Infact some of them offer real time torque reading while ignition advance is adjusted. With this ability you can find peak torque in each cell in the map. This is something not possible on the open road.
