Ok, new to this tuning thing, Havent actually started datalogging and adjusting yet, but did create a base tune, havent installed the tweecer yet tho.

Now my question is, what does the load effect, Now I do plan to adjust this to get the 100% load going at WOT. But does this effect power in anyway? or what? It said to adjust it but what does it really do?

thanks!

I somehow missed your Q

Better late than never

Since you are forced ... this is very important for you

You wanna nail this down VERY early in your efforts
or else
You will have to redo lots of your work as when you do
the load scaling change ... it will cause a kind of global
thing and hose up your previous efforts.

It is a bit involved to say the least

Here is what I would do

Poke around in the threads on the .org site and focus
on the 94-95 boys.

btw ... you have to be careful over there
as
The Fox boys take it for granted ... Our stuff works like theirs

Don't get side tracked with the Fox stuff as in this case ...

IT IS DIFFERENT

Look for where they talk about the load scalar switch
and
Notice how the t4m0 and j4j1 each deals with them

You got two columns of data to be concerned with

IIRC ...Depending upon your chosen value in the load
scaling switch, you use one or the other data column

Be sure and double check this info ... but anyway .........

I poked around and quickly found a 3rd gear blast I
already had converted to screen shot form from some
past post or file I sent to someone

Although its a little shy of my normal max effort
test method in the rpm's

You can see both columns at work for an idea about
the point I'm trying to get across here

Hope that helps

Ok just did some reading, found a really good thread over on the eectuning.org forums (http://www.eectuning.org/forums/viewtopic.php?p=33169&sid=f634199fad2a36c73bce51fc671c5e0c)

Basically what I got from it if your load scaling switch is set to 0, it takes Acutal load and processes it through "sealevel load scaling vs rpm" and makes load = loadX which i what your after, Now while data logging you need to have Load and Load % (load % being loadX from what Ive gathered) checked. Your goal is to modify "sealevel load scaling vs rpm" to make your load % be close to 100%. In order to do this you change the numbers in that table, lower the numbers to make your percent go up and raise the numbers to make the percent go down.

Now, is what ive gathered from that thread correct, or did I misunderstnad something?

Yes it is my understanding you use Load X values

I have never logged more than low 130's

Since I've optimized each table and other areas in the file
controlled by load individually ..............

I'm not about to do the scaling since its a global kinda thing

Just too much work to do all over ... again

I just can't see how my going over the greatest load row
in the various tables by that small amount is all that bad
of a thing.

Now if I showed values in the high 100's like some of the
forced boys ... that would be a different thing.

There's a great article over on the twEECer Yahoo forum:
http://autos.groups.yahoo.com/group/tweecer/files/LOAD Scaling/

It goes over what is going on w/ the load values as well as the ways to change them to fit your combo.

This article was a great help getting a tune ready for my supercharger.

interesting, But I still cant input the values I need in the load scaling, it doesnt accept them, I think im just gonna set the switch to 1
