RT130 – Final Release


Here are the SHO NUT Performance-only updates you will need.  Simply replace/add to the existing files after installing the above final release.


Data Directory: (free update, work in progress, last update 7/17/06, thanks Adam Parrott, SHO NUT/Adam client-only additional updates available, e-mail us to request the latest version, current as of 9/10/08)  For the X2J BE strategy, please scroll down to Tuning Services below. (free update, work in progress, last update 5/13/06, thanks Adam Parrot, SHO NUT/Adam client only additional updates and support coming soon)  For the D4U1 BE strategy, please scroll down to Tuning Services below.


MAF Directory:


We are working on a more complete page of our own, but for now, here are some files to view (note that any comment about datalogging only applies to the RT, and not to the base model):  – stock X2J binary (MTX SHO)  – stock D4U1 binary (ATX SHO)

For the above 2, download the latest software from the TwEECer site, install, and open the .bin files to look at stock SHO settings.  – early software datalogging shot, stock car  - early software datalogging shot, blower car - exported log, blower car - intermediate software datalogging shot, stock car - Excel chart of RT datalogged parameters  - exported datalogging shot, stock car - Excel chart comparison of secondaries always open and always closed for a stock SHO - emissions run with +10 spark (was actually closed throttle)  - emissions run with +5 spark  - emissions run  - intermediate software datalogging screen showing MAP and WB  - experimental DIYNO screen (not in released software)  - Excel plot of measured AFR vs HEGO voltage  - blow up of above  - Log Analyst plot of Lambse (commanded fueling) vs measured AFR (actual fuel)  - intermediate software datalogging screen  - intermediate software settings screen  - example of x10 VSS multiplier - Sample Datalog, 12 second run in our blower SHO - My current program for my blower car, last updated 11/16/06, T-trim with a 3.125” pulley, ACCEL yellow 48 lb/hr injectors, high-po FPR, Boost-a-pump, Lightning 80 MAF, +40 cams - still needs lots of tuning, use Compare Utility in CalEdit and compare screen by screen.


The TwEECer software will also interface with an external datalogger to log external signals in the same logfile as the logged EEC parameters, such as a wideband (WB) O2 sensor and a MAP sensor, and now a G-force sensor on our Performance page ( ), or even just volts. These loggers are purchased from DataQ for $25 and plug into older laptops via the COM port (DB9 Serial COM for old laptops that actually have a COM port) or, for $50, for newer laptops that only have a USB port (USB COM).   - correct settings for the 194 DataQ and a PLX WB, GM 3 Bar MAP sensor, and PLX G-force sensor - simply don't check the channels you don't have. Remember to use 148 if you have a DI-148 instead of the DI-194 shown in the example. The first setting for each channel is the transfer curve, and the 2nd setting is the display location. HL and Run are only visible on the digital screen, and show up in the rightmost column of numbers (the labels don't match). If you are having ground offset issues, or need to make a custom transfer curve (such as the AutoMeter full sweep fuel pressure gauge as ATM-FP is no longer hard-coded) then select an unused transfer curve and edit the corresponding .DBF file in the Data directory of STKR 1.30, such as ZEITRONX.DBF, using EA or Excel. Some transfer curves are hard-coded and can't be edited (and thus their .DBF files don't appear in the Data directory). Use the Volts transfer curve to read the voltage input to the DataQ when checking for ground offsets, confirming the data points for a custom curve, or just reading volts in the 0-10V range. NOTE – when enabling DataQ, you may have to make the changes, then close CalCon BEFORE you try to log, and then re-open before trying to log. If you don’t, sometimes you will get an error when you try to log without saving the changes first by closing the program.

For a PLX M-200/250-300 WB, connect the black PLX wire to the ground terminal on the DataQ (as well as your power ground), and connect the white wire to Channel 1 on the DataQ. For the PLX SM-AFR, refer to this manual page 3, and GND goes to the ground on the DataQ, while WB goes to Channel 1 on the DataQ.

NOTE – do NOT install the DataQ software unless you need to use it for looking at signals other than what comes from your WB.  Doing so will over-write the CalCon UltimaSerial drivers with trial ones, so that you get this message -

If you have done this, download this update and install the two .exe’s inside in order:


We also use and recommend the EEC Analyzer software – this software will analyze your TwEECer logs, MAF curve, injector settings, ISC settings, and help you determine the correct injector settings, give you a corrected MAF curve (based on either KAMRF or WB feedback), and MUCH MUCH more.  It does all the math and mental work of getting your tune accurate, and allows you to concentrate on tuning.  Even if you don’t buy it right away, it has very well written explanations of injector settings, MAF curve settings etc. etc. etc.  VERY well worth the purchase price.


We also use and recommend the Binary Editor (BE) software – this software is used to read and write to the TwEECer and is more user-friendly and offers more features than the CalEdit/CalCon software included with the TwEECer.  We offer support for the SHO for BE via Adam Marrer of POPS Racing (see below).  It is also VERY well worth the purchase price.  One important advantage of BE is that you can directly interface with third party hardware for datalogging, at the digital level, for error-free datalogging.  This eliminates all the ground offset and calibration issues with doing a digital-to-analog-to-digital conversion with a DataQ.  For example, you can directly interface with the PLX iMFD data stream via the PLX-iMFD-SM-USB or PLX-iMFD-DL (See our Performance Page) that we sell for up to 32 additional external PLX channels (similar interface exists for Innovate).  As well, you can also interface with the DataQ as with CalCon – all at the same time.

Tuning Services and BE Strategies


We recommend the following for tuning services, both local (dyno) and remote, for any Ford car, including the V6, V8 and EcoBoost cars/trucks:


Adam Marrer of POPSRACING



Adam Marrer has tuned nearly a thousand vehicles, including SHO's.  We have been working closely with Adam Marrer to refine the V6 strategies for BE, so he comes highly recommended by us as a tuner who is able to help people in a timely fashion.  Given the amount of work that Adam Marrer has put into the X2J strategy for BE, INCLUDING detailed descriptions of/instructions for each setting and numerous previously unknown settings, we have decided to make the BE Strategies available as a paid service via Adam Marrer.  You can get the X2J.cry strategy for BE (and any subsequent updates) directly from Adam, and the strategy must be registered by Adam to be functional.  A registration is to one machine (not a VM machine), and includes any future updates.  The fee schedule is as follows (this fee represents a substantial discount compared to the usual charge for a BE strategy from Adam Marrer):


Existing SHO NUT TwEECer customers (including Midwest SHO, SHO Bros and SHO Source sales through SHO NUT) for first-time TwEECer purchases prior to 5/12/10 $65

To pay this amount (the payment goes directly to Adam Marrer), click here:



New SHO NUT TwEECer customers (including SHO Source sales through SHO NUT) after 5/12/10 *or* people that bought a TwEECer 2nd hand that was originally bought via SHO NUT $110

To pay this amount (the payment goes directly to Adam Marrer), click here:



Once you have paid the fee, please contact Adam Marrer at the contact info above to get your strategy and get it registered to your computer for BE.


If you are not a SHO NUT TwEECer customer, or are looking for a D4U1 strategy, or are looking for tuning other than the V6 SHO (inccindlug 2010 and up Ecoboost), please contact Adam Marrer directly via the contact info above.
