Throttle-Up Industries Training Tutorial
– Tutorial Introduction –
Introduction
Welcome and congratulations on purchasing what we believe to be the most innovative and
interactive training tutorial available on the market today for HP Tuners. Whether you are new
to tuning or experienced, it is not a beginners, intermediate or advanced course…it is a complete
course for everyone. It’s the only tutorial you will need to buy. It’s a 345+ page tutorial full of
information, pictures, videos, PowerPoint presentations and tuning tips based on your EFI
systems, their sensors and how they work. This information, while specific to a GM V8 platform
is also somewhat generic in nature and can be applied to the Ford and Dodge platforms as well.
It can also be applied to EFI Live as well as other standalone tuning systems.
Tuning Tutorial Overview
The Throttle-Up Industries Tuning Tutorial approach to learning is to start with the basics and
understand what and how the components operate. From there we formulate a solid
foundation to build on. You will learn the how and why…..not just what to put where. You will
be able to recognize situations of good and bad, and know how to formulate corrective action to
correct the situation(s). We believe you will be prepared to take on any tuning and even
mechanical problem identification/solving with what they call in the engineering field “root
cause and corrective action”… What really is happening? What is causing the issue/negative
result and based on a good understanding of how it works, what needs to be done to make it
right?
The tutorial is made up of 11 Modules in PDF format that is completely downloadable and can
be saved to your computer. You will need Adobe Acrobat Reader to view the tutorial. If you
don’t already have it installed on your computer, it can be downloaded here:

· Six (6 )PowerPoint presentations detailing the specific procedure steps associated
with the tuning process.
· For those who don’t have PowerPoint on their computers, you can download a
free PowerPoint Viewer here:
· https://download.cnet.com/PowerPoint-Viewer/3000-2075_4-75450958.html
· Presentations include:
1. Advanced EFI and Tuning – supports the above 11 Course Modules.
2. Wideband Setup – supports and adds detail to Module 4.
3. Scanner Filter – supports numerous modules as far as logging and filtering
for accurate street tuning.
4. Strategy and Base Tune Development; perhaps the most valuable part of
this course…table by table review and approach to tuning. J
5. MAF Tuning; detailed procedures for MAF tuning and scanner use.
6. VE/VVE Tuning; detailed procedures for VE/VVE tuning and scanner use.
Also included in this tutorial are embedded videos which will walk you through selected
course subject material to further embellish your goals and objectives of learning HP Tuners.
We also utilize PowerPoint presentations to also support your training. If you do not have
PowerPoint on your computer, the link is above for downloading.
We want to warn you that this is not a tutorial that will tell you what values to put in what table
based on some arbitrary platform configuration. This is not how you learn! Our intent is to
mentor you in the detailed theory of operation of an EFI system and its PCM, so you can
formulate a tune strategy and values. Additionally, we integrate detailed operational
instructions on the HP Tuners VCM Editor and Scanner so they become yet another important
tool in your box to identify, isolate, diagnose, develop updates and finally verify your results.
What this means is you will be able to observe a situation and based on the knowledge learned
from this tutorial, you will understand what is happening as well as why. Once you are armed
with that detailed knowledge, the corrective action becomes intuitive.

Tutorial Modules 1-9 will take you on a fantastic journey to:
· EFI systems review: sensor discussions, Fuel /injector system design/verification and use
· Alcohol effects in fueling, using E85; now you will have to tune in Lambda J
· Ignition timing and spark control; street tuning approach for power
· MAF/VE airflow including math the PCM is using to derive its fueling
· Wideband selection and setup; analog, serial and OBD II interfaced to Standard and Pro MPVI’s
· Injector selection and tune data input; the good, the bad and the ugly……
· End Of Injection Timing – calculate new cam events and Injection points for that big cam
· 2 huge sections on HP Tuners Editor and Scanner walk through, discussions and use;
detailed table by table review and all commands available to use
· Gen III vs. GEN IV comparisons and similarities
· Scanner filter design, implementation and verification
· Virtual Volumetric Efficiency tuning
· Virtual Torque Model tuning
· Torque Management
· Adaptive Idle – everything you ever wanted to know but were afraid to ask…
· Forced Induction options
· HP Tuners Enhanced Operating systems; their description. Selection and activation
· HP Tuners patches; how to get rid of some of those nagging nits…..
· Tuner lock
· Detailed Step by Step procedure for modifying a Tune File
· And much more………….but that’s not all……..
What you actually bought the tutorial for…..Tuning!
Tutorial Modules 10 and 11 are the final modules and the ones that will pull it all together. In Module
10 we begin the base tune development based on all the knowledge we have accrued through the
first 9 modules. Module 11 we actually get in the vehicle and begin the Idle, MAF, VE and WOT
tuning as well as detailed logging with the HP Tuners VCM Scanner.
I know. It seems like a lot of boring reading and work to go through before even changing a table,
but I’m sure you will thank us in the end. In Modules 10 and 11 we review and formulate your
tuning strategy and how to go about the tune based on your platform build.
