New Tweecer Guy

[deric89460]

Ok gut I am new to the Tweecer game. I have a 94 mustang with just gears and exhaust. I bought and installed the Tweecer RT I have done some Datalogging already but I'm not sure what to change. The plan is to Drag race the car so I'm looking for some Ideas and timming tunes and anyother tunning that will help. Also if someone could explain what and how to chang the timming tables Thanks

There is a tune on there for aggressive spark tables.
Welcome - [tunexchange: Proudly burning chips and rubber since 2008]

I recommend downloading binary editor. Load that tune and compare it to your stock one. You can see then how spark and fuel is changed.

I loaded my stock ( I thank anyways) into Cal Edit and look at Functions I don't see a filled out graf just a graf and a box with numbers in it. also you said there a tune for agressive timing tables, where do I find this. Thanks for you help

correction I had forgot to click on my stock tune so Now I have loaded grafs but where is that timing tune thanks...

Go to the website I linked above. You need to download Binary editor (BE)to be able to load the aggressive spark/fuel tune. Wes has a walk-through on the website. It shows how to use the site with BE.

I'd advise you to master basic operations BEFORE you upload stuff :Word:

You don't wanna slam just anything in there you know nothing about
and
How it might adversely effect your Stang

Just take it easy and focus on the simple stuff at first

Upload your OEM info and save it as such

Then ... make a simple change you can know for certain makes a difference
such as adding 200 rpm to the idle.

Then save the modified file and save it as such

Then upload the modified file and see if your rpm rises

Now ... see if you can upload the OEM file and the idle drops

If so ... You'e mastered
building a file
saving that file
uploading that file
switching between files

Now ... master datalogging

Nothing more than 30 seconds to keep the files nice and small

You will have to build a payload

After the payload is built ... you can do some simple test runs

The idea is to focus on one and only one application at a time

Here is a simple example for you to get the jest of dlogging

Do a cruise at a steady speed of like 30 mph on level ground and
dl for only 30 seconds

Do a second cruise ... exactly the same speed ...
exactly like before on level ground ... for the same 30 second time period

The differene this time is at 15 seconds into the test run go to the floor
with the skinny pedal

You see ... the first file is your baseline or reference point

You then look at the second file and you will find .........

You will be able to see ......
throttle body changes
load changes
rpm changes
loop state changes
spark changes
and much much more

anyway ... I suggest you get familiar with the basics

The only way you are gonna see the possibilities
is to play with it and do lots of basic datalogging to understand what
the pcm is doing with the data the various sensors are sending it

Ok maybe I typed the wrong question... does anyone have any input they would like to give for a stock motor with a 5-speed and 3.73s looking for wide open throttle tunes... I have date logged and even played with rpms and fan speed.. just looking for timing ideas and other secrets that other tuners have found...thanks

You can add a few degrees of timing in the upper end, but otherwise don't bother. On the stock motor, you'll hardly get any more power from the stock tune.
