A basic guide to uberdata / crome / tuning in general.
Article on phearable.net (click here)
This article is not going to teach you how to use uberdata/hondata/crome or understand map scalars etc...
But it will give you the basic understandings to tuning a vehicle etc.

So if your street tuning with a wideband your not really monitoring hp/tq numbers but trying to get your a/f ratio as close to 12 parts fuel : 1 air at WOT and as flat/gradual as possible to that point?

Correct. Keep in mind ignition timing is something very important to also monitor. It is very hard to figure out how much timing to actually run without using a dyno to find MBT or using an advanced knock monitoring utility. So, unless you actually have some experience under your belt, it is usually not a good idea to try & street tune a vehicle without being able to monitor knock conditions.
There is tons & tons of information you could gather concerning tuning & methods, tools etc. This is just a small icebreaker.

In 99% of cases with an n/a setup you won't need to log knock conditions due to the fact that you can hear the pinging in most cases & you can simply monitor the spark plugs.
There are a couple of units you could use. Plx just came out with one, but I am unsure as to how well it actually works.

Huh ?
What air fuel ratio you choose to tune your vehicle to at WOT is really up to you or your tuner. I provided the general a/f target a/f ratios in the article.

You are incorrect. You can tune everything you could tune on hondata etc.

You obviously don't understand vacuum....
Do some reading, there are plenty of beginner DIY articles.

Yes, vacuum pwns j00. If you can drive on partial throttle on low cam, don't you think there should be something that represents that condition in the software? Do a little reading and tell us more. In the mean time, don't confuse people who aren't familiar with all of this, it will lead to stupid questions later.

Re: (drdisco69)
first off i'm not trying to knock the programs or even try to insinuate that i am an expert when it comes to tuning.i think thats why i am asking these questions so i can figure out how to really use uberdata . since no one took the time to make a users guide. like for instance w/ a vafc it kind of has the seperation of part and full throttle for u. but w/ u guys telling me about the vaccum bar readings really puts it into perspective on how to really work the program thats the only thing i could not figure out about it and datalogging

mtber is right. When tuning for a target A/F ratio, there are many factors that come into play. Until you have enough data to make an educated decision regarding the A/F ratio, a safe guess is about 12:1.

for a NA car, 12.0 is WAY TOO RICH. Even the CTR piston LS/vtec with Blox blah blah cams and portwork with a 2 layer gasket saw 13.0 AFRs on 93 octane at lowest. 12.0 is a good guideline for BOOSTED cars - you'll just lose power if you tune that low on a NA car.
