Getting Started with Tuning Your EEC-IV Using a TwEECer RT
« on: February 24, 2009, 10:21:17 AM »
The following assumes that you are using the TwEECer supplied software; CalEdit & CalCon.
There are better software options available...

Here is some stuff not really addressed in the TwEECer manual, as downloaded from http://www.tweecer.com/downloads.htm

1. The "Update Only" checkbox has a bug that will randomly corrupt the tune when it is loaded into the tweecer. Always double check that this box is not selected after making modifications, as it seems to be check by default. The checkbox shows at the bottom of each of the tabs.

2. When datalogging make sure that you have created a payload and saved the tune (.ccf file) with the "Data Logging" checkbox selected. If this is not done then CalCon will not show any activity while the engine is running.

3. Do not remove the file "Logfile" from the folder "LogFiles". This file is a format file that is used each time a datalog is created. Without the file in this location, datalogging is not possible.

Here is a summary of some of the first changes that need to be made when starting out with the TwEECer. After performing these changes it would be a good idea to do some data logging and verify that KAMRF 1 & 2 are not too far off from 1.00. The EEC-IV seems to have a maximum adaptive ability of 12%. If you are getting readings of 1.12 or .88, then you have maxed out the ability of the computer to make changes with the KAMRFs.

Mechanical/Hard Tune Changes
1. Set Base Timing to 10*
  a. Timing adjustments will now be made with the tuner
2. Set Fuel psi to 38-39, or install stock regulator
  a. Fuel adjustments will now be made with the tuner
3. Set Base Idle
  a. Idle adjustments will now be made using the tuner
  b. Base Idle Reset Procedure:  http://sbftech.com/index.php/topic,1031.0.html
4. Ensure TPS is between .6v to 1.1v.
  a. Anywhere in this range is acceptable
5. Check for Diagnostic Codes
  a. Any problems should be corrected

TwEECer Changes
1. Turn off EGR function (If system has been removed)
2. Disable Thermactor Control (If system has been removed)
3. Set idle
4. Change MAF Transfer (download if available)
5. Change Injector High/Low Slopes per TwEECer Manual.
6. Change CID scalar

When you purchase a tweecer or tweecer RT, you are only buying the HARDWARE.
The software supplied with the tweecer is free to download from the tweecer site...
http://www.tweecer.com/downloads.htm

The 'editor' available on the tweecer site is called CalEdit.
The datalogger available on the tweecer site is called CalCon.

Both of these software programs had several glitches, and it was starting to look like they would never be fixed. They didn't make the software unusable... just tougher to work with, and harder to learn for noobs.

This is where BinEditor & EECAnalyzer come in.
BinEditor (aka BE) is a single program that incorporates both the editor and the datalogger.
EECAnalyzer (aka EA), is a separate program that is used to analyze datalogs and make reasonable suggestions for tune changes.

The creator of BE/EA is a fellow Mustang enthusiast who is pretty active in the continued development of the software.

More info can be found here...
http://eecanalyzer.net/

Both can be purchased here...
http://eecanalyzer.net/downloads/

Both EA & BE are free to download, but the registration fee must be paid for full functionality.
If you are curious about these programs, you can download them and get a feel for how they function.

The following is some info on Moates.net gear.


Here is a breakdown of what you will need to buy from moates...
F2A - An adapter between the burn1 and the F3 chip module
F2E - Allows you to read directly from the ford ecu. Handy, but not needed, as all of the common .bin tunes are already posted all over the interwebs.
F3 - This is the chip that plugs into the port on the back of the ecu
Burn1 - This is a standard piece of hardware used for many applications. We need to use the F2A as an adapter between the burn1 and the F3 chip.

Basically, order everthing on these links...
Ford Adapters:  http://www.moates.net/index.php?cPath=25_35
BURN2 Chip Programmer:  http://www.moates.net/product_info.php?cPath=51&products_id=197


**As of February of 2009**
The above hardware has now been superseded, by a NEW product from Moates: The QuarterHorse
http://www.moates.net/product_info.php?cPath=50&products_id=199

Currently the QH only supports 1 tune, but with the additional functionality to make changes to the tune in REAL TIME, multiple tunes are less of an advantage.
(note that the F3 chips can have a switch soldered in, to allow 2 tunes to be used)
The only advantage the TwEECer RT has over the QH, is the 5 tune switch.

The QH is fully functional with BE/EA, as well as TunerPro and EECEditor.

I am attaching 2 PDF files to this post.

The first document is the latest revision to the the Tweecer Beginners Manual.
The info in this document doesn't cover ALL topics, but it should help clarify some questions for noobs...

The second document is the GUFB.
This is the Manual created for Ford Engineers responsible for recalibrated the Fox Body ecu's for new applications.
Parameter names and definitions are all covered in detail.  All LOGIC steps are covered in detail.

Here is some basic info on the J3 port & chip modules...


Quote
For examples of what a J3 chip looks like, pull up a pic of a Moates F3...


Or the tweecer module... (shown installed on the back of the ecu)


The factory ecu can't be reflashed/reprogrammed, so we use a separate chip (J3 chip) to write a tune on.  Once the J3 chip is plugged into the ecu, the settings/tune in the J3 chip over-ride the factory settings.  The factory settings are still there, and you can always return to the stock tune by simply removing the J3 chip.

Will I need to load a a9l .bin to start? Are there any base tunes for H/C/I setups? I am gonna have to do alot of studying until QH gets here.
Yep, you would want to start with the stock tune that you have in your ecu.
I suggest the following order...
1. Change the idle rpm speed, just to make sure that setting changes in BE result in the change you desire.  This gives you a chance to sort out any little problems that may arise from installation.
2. MAF Transfer and Injector slopes will be your first change. If you have stock 19's then the stock settings are already correct, and you only need to change the MAF Transfer.
BE and EA will have a ton of MAF Transfers to choose from.

Another source that I forgot to mention is Tunexchange.  This site was started by a fellow Mustang enthusiast who is now working as a professional tuner; Wes (Stanger007).
Wes has created 'templates' that allow you to quickly and accurately load settings for some common upgrades.
For example, you could upload a template to your BE tune for 24Lb injectors.  This template would have not only the slop settings, but also several other settings that have proven to help.

I'm attaching an extracted portion of the TwEECer manual for easier reference...
The listed injector values should be viewed as a starting point for tuning, as adjustment may be needed.

The attached documents were posted by decipha on eectuing.org as guides on how to set a baseline idle and achieving accurate fuel settings.
