APR's Enhanced Modular Chipping System™
(EMCS™) is an industry leading technology that brings many
new features to the automotive enthusiast. EMCS technology was developed
exclusively by Audi Performance & Racing, LLC and demonstrates APR's
continued commitment to lead the industry with the most technologically
advanced products available. EMCS consists of three important parts
that work together as a cohesive unit: the EMCS module (which is
soldered to the engine computer board), the EMCS on-board software
(the software that is on the module), and the support software that
is used to program and reprogram the module. APR's EMCS is a truly
modular system that allows for future enhancements and features
to be added as they are developed without the need for additional
hardware.
EMCS makes the following
advanced features possible:
FlipSwitch: Using
the cruise control buttons, you are able to switch between up
to four separate ECU programs of your choice. Examples of possible
chip programs include stock, performance chip, 100 octane program,
valet, etc.
User Reprogramming and Reconfiguration:
This gives the user the ability to reprogram their ECU with
the latest software updates and to reconfigure their ECU for
different preferences or to function with different hardware.
This function requires the optional programming adaptor.
Security Lockout Feature: Prevents unauthorized
personnel from accessing EMCS functions. The user may select
any 1 to 4 digit security code. The security code is entered
using the cruise control buttons.
Fault-code Erase: Allows you to erase
and reset engine related trouble codes without having to use
a specialty tool.
Throttle-body Realignment: allows you
to manually perform throttle-body adaptation.
VERY IMPORTANT! Precautionary
Measures!
Please read the following carefully before installing APR EMCS™
in your vehicle.
Never while driving the
vehicle attempt to change chip modes. (It is possible to change
modes while driving or with the car idling but it is not recommended.)
This is dangerous due to the fact that one must look at the
dash to locate what mode they are in. Program switching should
always be done with the car off and the key in the on position
or with the car stopped and the engine idling.
DO NOT attempt to use anything
less than certified 100-octane unleaded fuel with programs intended
for 100-octane fuel. *Lower octane gases are NEVER to be used
with race-gas programs regardless of how much octane booster
or other additive is used Ð OCTANE BOOSTER AND A LOWER OCTANE
FUEL IS NOT THE EQUIVALENT OF 100-OCTANE RACEFUEL. Failure to
comply with this guideline could result in expensive damage
to your vehicle. APR will not be responsible for any damage
resulting from racing fuel programs.
EMCS features are not intended
to be used to deceive dealerships or any other party with regards
to warranty work. EMCS is intended to function in a manner closely
resembling that of the stock ECU programming so that car diagnosis
and repair is unimpaired.
Certain engine software
programs may not meet state or federal requirements regarding
emissions or other such regulations. These programs are intended
for off-road use only.
Installing Your EMCS ECU
Follow the normal ECU installation procedures
included with your EMCS ECU. Be sure to turn the ignition ON
(engine not running) and leave the key in the ON position for
at least three minutes before running the car.
EMCS features are accessed on all model year
2000 and up cars using the cars' cruise control buttons. From
here on, these buttons will be referred to as they are labeled
in the picture: SET, RESUME, ON, CANCEL, and OFF. EMCS will
not interfere with normal operation of the cruise control.
Security Features
Note: If you did not opt for the security
feature, you can skip this section.
The security feature allows you to lock or unlock
EMCS function selection. When the EMCS module is in the LOCKED
state, it will not be possible to select any other EMCS features
or toggle between ECU programs. Putting the EMCS module into
locked state will lock in the current configuration.
Example: You have selected the second
ECU program (chipped). Next you select the LOCKED state. The
ECU will now run the program that you had previously selected
(chipped). If you attempt to switch chip states or use any other
EMCS function by depressing the cruise control buttons while
in the LOCKED state, you will receive no visual feedback and
the requested function will not run.
If your EMCS product is equipped with the security
feature, then you MUST enter the security code correctly before
you will be able to access EMCS features. The EMCS module will
always default to the LOCKED state when ECU power is interrupted
and the ECU will run the first program (usually stock). The
EMCS module will not reset when the ignition key is turned OFF
and back ON. You will not loose your current EMCS settings unless
the ECU losses power (i.e. the ECU is unplugged or the battery
is disconnected.)
Procedure to put the EMCS module into
the UNLOCKED mode
1. Locate your unique security code.
2. Turn ignition key to the ON position. DO NOT
START THE ENGINE. The check engine light and EPC light should
stay permanently illuminated.
3. Ensure that the cruise control slider button
(this is the inner cruise control button) is in the ON position.
If the cruise control button is OFF, turn it ON.
4. Enter the first digit of your security code
by pressing the SET button on the cruise control stalk the same
number of times corresponding with the first digit of your security
code (ex. for a "9", press the SET button nine times).
You do not have to hold the set button for any specific period
of time- just press the button and release it.
5. Use the inner button on the cruise control
stalk to register each digit of your security code. To do this,
slide the cruise control button from the ON position to the
CANCEL position. (If you go past the CANCEL position to the
OFF position it is OK, just turn the cruise control back to
the ON position and proceed with the next digit).
6. Enter subsequent digits in your security code
by following the same procedure you used above- depressing the
SET button the number of times corresponding with each digit.
Do not forget to register each digit by sliding the inner cruise
control button to at least the CANCEL position. Also, ensure
that the cruise control slider button is in the ON position
before proceeding with the next digit. If you make a mistake
entering your security code, press CANCEL and then start over
with the first digit. It is not necessary to turn the ignition
off and back on if you make a mistake.
7. After you have correctly entered your security
code and the cancel button is pressed after the last digit,
the check engine lights and EPC lights will start blinking alternately
to signify that the code was entered correctly and that the
EMCS module is unlocked.
8. You will now be able to access all other EMCS
functions that your ECU is equipped with until the EMCS module
is relocked.
Procedure to put the EMCS module into
the LOCKED mode
1. Ignition key must be in the ON position. Engine
can be either running or not running.
2. Push the inner cruise control button all the
way to the left (the RESUME position) and hold. Keep holding
the button in the RESUME position until the check engine light
blinks three times a second and release the button. The EPC
light will also be lit while the check engine light is blinking.
If you have purchased the fault code erase and throttle body
adaptation options then you will need to wait while the light
first blinks once a second (after five seconds), then twice
a second for five seconds, and finally three times a second.
The check engine light and EPC light will blink alternately
for three seconds indicating that the EMCS module has been locked.
Overview of EMCS Security Feature Instructions
The EMCS module will always default to the LOCKED
state with the first program selected.
The ignition key must be in the ON position with
the engine not running in able to enter your unique security
code.
Enter your security code by using the cruise
control SET button and use the CANCEL button to register each
digit of the security code. If you make a mistake while entering
your security code, press CANCEL and begin again with the first
digit.
When the security code is correctly entered,
the check engine light and EPC light will blink alternately
for three seconds to indicate that the EMCS module has been
unlocked successfully. The same blinking pattern will occur
when the module is relocked.
The module can be locked with the engine running
or not as long as the ignition is ON. This is accomplished by
holding the RESUME button until the check engine light blinks
three times a second and then releasing the RESUME button.
The EMCS module will stay in the same chip mode
until another mode is selected. This mode will not be affected
by turning the ignition off nor will this mode change due to
the EMCS modules locking state.
FlipSwitch (optional)
The FlipSwitch option allows you to switch between
two or more ECU programs of your choice. Program selection is
facilitated by using the cruise control SET button.
WARNING!
DO NOT ATTEMPT TO SWITCH PROGRAMS WHILE THE CAR IS IN MOTION!
ALTHOUGH EMCS WILL ALLOW PROGRAM SWITCHING WHENEVER THE IGNITION
IS ON, IT IS NOT RECOMMENDED TO SWITCH PROGRAMS UNLESS THE ENGINE
IS OFF AND/OR THE CAR IS MOTIONLESS. ATTEMPTING TO SWITCH PROGRAMS
WHILE DRIVING COULD BE DISTRACTING FOR THE DRIVER AND COULD
RESULT IN AN ACCIDENT.
Swapping Program Modes Procedure
1. Locate your EMCS configuration sheet that
accompanied your ECU.
2. Turn the ignition key to the ON position.
3. Be sure that your EMCS module is in the UNLOCKED
state (if equipped with the security feature). Unlock the module
if required. Remember that you will not be able to unlock the
module if the engine is running.
4. Make sure the car is not in motion.
5. Hold down the cruise control SET button to
select the appropriate engine program. After five seconds, the
check engine light will begin blinking once a second. This will
continue for five seconds. Next the check engine light will
begin blinking two times a seconds for five seconds. This pattern
will continue for three blinks (depending on the number of programs
that are configured) and will end with four blinks a second
(which will appear as a sequence of continuous blinks.) The
number of blinks per seconds corresponds with the program number
on your configuration sheet:
Program 1 = 1 blink per second
Program 2 = 2 blinks per second
Program 3 = 3 blinks per second*
Program 4 = 4 blinks per second*
(* if equipped)
6. The cruise control set button when the indicated
blinks per seconds corresponds with the program that you wish
to run. Ex.- To run the program in slot 2, hold down the cruise
control SET button until the check engine light blinks twice
per second and then release the SET button. You will now be
running program number 2.
Note: If your EMCS module is equipped
with two programs, then you will never see 3 blinks or 4 blinks
per second. The pattern will end with two blinks per second.
Similarly, if your EMCS module is equipped with 3 programs,
you will never see 4 blinks per second.
Remember: If your EMCS module is equipped
with special software for particular hardware and/or fuel DO
NOT attempt to run those programs without the correct matching
hardware and/or fuel. This could result in serious damage to
your car.
Fault Code Erase/Throttle-Body Alignment (Optional)
The EMCS fault code erase feature can be used
to erase all fault codes present on the engine computer. The
throttle body alignment feature can be used to manually run
the throttle body alignment sequence. These features are only
available as a pair. Both features are activated using the cruise
control RESUME button.
Erasing Fault Codes / Throttle-Body Alignment
1. Turn the ignition key to the ON position.
2. Be sure that your EMCS module is in the UNLOCKED
state (if equipped with the security feature.)
3. You will use the cruise control RESUME button
to access these two functions. To erase fault codes, hold the
RESUME button until the check engine light starts blinking once
per second and then release the cruise control button. The EPC
light will stay illuminated while the check engine light is
blinking (this is to distinguish between the program switching
mode.) To run the throttle body adaptation sequence, hold the
RESUME button until the check engine light blinks two times
per second and then release the cruise control button.
Note: Throttle body alignment is only
possible when the ignition is ON and the engine is not running.
Also, only attempt to run the throttle body adaptation sequence
when the engine is cold.
