Whats Code59?

• Code59 is free stuff to help you tune your truck
  for better power, reliability, mileage, and
  drivability.
• Code59 includes
• Tools to help with tuning
• Base binary images (chip files) to get started
  with, for various builds and injector sizes
• Definition files for TunerPro RT so that it
  understands Code59

5
Why use Code59?

• We made it better improvements to the base GM
  operating system to make it easier to tune,
  with integrated Wide-Band o2 capabilities. Also,
  tools like AutoTune to do a bunch of the heavy
  lifting for you to get started.
• Purchased chips are hit-n-miss some will work
  ok on your truck, some wont.
• Does what the aftermarket systems (FAST,DFI) do,
  for a lot less.
• You can do this stuff! Tune it yourself to save
  , and get better results than what you can buy
  off the shelf.

6
What do I need?

• Wide-Band o2 sensor setup
• Recommended units
• PLX SM-AFR
• Innovate LM-1 (LC-1 is ok, too)
• Many others supported
• check the code59.org website for list
• Wide Band sensor outputs must be wired into the
  ECM, Pin F14 for the Wide-Band signal and any
  good ECM ground for the signal ground. (Pin B9 in
  the center connector is a good place for ground
  or ECM Case)

What do I need?(continued)

• Ostrich, or chip burner
• Huh? Ostrich WTF is that?
• Moates Ostrich Allows you to make tuning
  changes on the fly while the vehicle is running
• http//www.moates.net/product_info.php?cPath31p
  roducts_id169
• Burner
• Unlike the Ostrich, this wont do changes while
  running
• you have to shut it off, pull the chip, re-burn
  the chip,
• put the chip back in lather, rinse, repeat.
• The upside - cheaper.

Getting Started

• Ive got all of the abovenow what?
• First things first, get it all hooked up.
  Wide-band, Ostrich, Scan Tool cable.
• Download a suitable starter bin (one for your
  injector size) for your truck from code59.org
  download area. Put it in the TunerPro bin
  directory ltlocationgt
• Download the code59 ads and xdf files, and put
  them in the appropriate directory.
• Start TunerPro
• Make a few data logs in TunerPro to make sure it
  all works

11
How to hook up Ostrich to your ECM
12
What COM port is my ALDL Cable on?

• Before connecting your USB ALDL Cable, Right
  click on My Computer and go to Properties.
• Click on Hardware Tab and then go to Device
  Manager
• Pictures are for XP, Vista will look slightly
• different but how you look up the COM
• Port is similar.

13
What COM port is my ALDL Cable on? - Continued

• Expand the Ports (COMLPT) section
• Connect your USB ALDL Cable
• The New Com Port will Show up in Ports section
• Remember the COM port number as you will need to
  put this in the COM port setting in the TunerPro
  ALDL connection.

In this example it is COM4
14
What exactly is a Bin, ADS and XDF?

• BIN
• The actual code and information on the chip.
• ADS
• Translator to laptop on what words the ECM is
  speaking (english, spanish, canadian, etc.)
• XDF

40
Demo

• Show hookup, data collection.

41
Exploring the Code59 XDF

• In each section we have Organized all the
  Constants, Flags and Tables in common sections.
• Fuel, Spark, Boost, WBo2, etc.

42
Common Constants

• Closed Loop Temperature Enable
• RPM Limit
• EGR Shut Off

43
Closed Loop vs Open Loop

• CLOSED LOOP - allows the ECM to make fuel
  corrections. You never want to tune your vehicle
  in Closed Loop. You will be chasing your tail.
• OPEN LOOP ECM runs the VE numbers in your F29x
  table without making any corrections.

44
How to put ECM in OPEN LOOP?

• Do a find in TunerPro (CTRLF) for Closed and
  look for the item labeled Temperature for Closed
  Loop Enable (KCLTC)
• Set this to 151C to Force
• the ECM into
• OPEN LOOP

45
RPM Limit/Fuel Cutoff

• Cutoff Injectors are turned off at this RPM
• Resume Once RPMs drop to this setting,
  injectors will turn back on

• Make sure you set it for the correct number of
  Cylinders you have.
• Hey why does my V8 Ty shut off at 4000 RPMs
• Did you check the V8 Fuel Cut off and Not the V6
  Cut offJEFF ?

46
Disable EGR

• EGR - Temperature Level for EGR Enable (KEGRTEM1)
  Set this to 151C to disable.

47
Common Flags

• Wideband Flags
• Select the correct WBo2 flag for your sensor.
• Make sure only one Wideband flag is selected.

48
Basic Fuel/Timing Tables

• F28 This is essential our BPC Constant amount
  of time the injectors will opened.
• F29x Main Fuel Table
• F77x Boost Multiplier
• F1 Main Timing Table

49
Base Pulse Constant -vs- Desired EGR (F28)

• This table is always used regardless if your EGR
  is disabled or not. If disabled the 0 setting
  will be used. Best to set it the same for all
  cells.
• This is essential our Base Pulse Constant (BPC).

50
F29x Main Fuel Table

• F29x This is the main fuel table. This is the
  table Autotune works with.
• Cant go over 99.69VE in a cell
• Now you can fine tune
• the boost cells.

51
F77x Boost Multipler

• Used to add fuel when in addition to the F29x
  table.
• F77x is for big fuel changes
• across a MAP range.
• F29x is for fine tuning fuel
• Used when you run out of VE in F29x (99.69 is max
  VE)
• 95 of all your work will
• be in the F29x table

52
F1 Main Timing Table

• F1 This is the main timing table. This is
  where you would do 95 of your timing changes.
• Goes from 600 4800 RPMs and vac to 30 PSI

53
Ideal Fuel Ratio

• What is the ideal ratio?
• Cruise 14.0-15 1
• Boost 10.5-12.0 1
• Deceleration 15-201
• These are guidelines, based on knock and how the
  truck reacts you will want to adjust for YOUR
  vehicle. There is not a perfect answer here.

54
Where to begin?Driveability before WOT

• Adjust F28 Table in the base bin for you injector
  size until idle is somewhere in the 14.0 15.0
  AFR Range and then leave this table alone. Set
  all values in this table to the same number
• Put ECM in OPEN LOOP so it no longer controls
  fueling
• Idle Now fine tune idle cells to make sure it
  idles smooth
• TIME TO LOG Take it out for a drive. Get
  Driveablitily correct before boost
• Driveablity Drive while logging different
  conditions.
• Cruise
• Different conditions (uphill, different gears,
  level)
• Different loads (more people in the car)
• AUTOTUNE
• Put log and F29x TABLE into Autotune
• Copy new F29x table back into Chip and save chip
• Examine new F29x graph

55
What is a good tune?

• Smoother is better
• Make sure you dont have big VE changes between
  MAP/RPM cells. More than 5 VE difference between
  cells then look at those cells.
• Trust your WBo2 Sensor but use your NBo2 as a
  sanity check If you can
• WBo2 Says 12 AFR, NBo2 says 900mv, TRUST Sensor
• WBo2 Says 12 AFR, NBo2 say 300mv, SUSPECT BAD
  SENSOR

56
Examples Fuel Maps
Not too good Lots of Peaks and Valleys
Better Smoother Transition between cells
57
Autotune

• Excel spreadsheet that groups data samples
  together, averages them and gives you a suggested
  new fuel table based on inputs.
• Basically a lot of math to HELP you.
• Warnings
• Its just math, it cant see if a sensor is bad,
  garbage in garbage out, or other issues. Only
  works off the F29x table.

58
Autotune DEMO

• Before Starting you need to make sure the Excel
  Analysis Pack installed and turned on in the
  ADD-ONs
• Copy F29x table from your BIN
• Paste Into the FROM TunerPro Section in Autotune
• Make Sure AFR table in Autotune matches F29_AFR
  in your Chip
• Open Exported LOG into Excel
• Highlight All Cells in the LOG and copy
• Click on the Upper Cell of the NON_AE_PE Tab and
  paste the LOG file

59
Autotune DEMO

• Wait for Autotune to Calculate Will take some
  time depending on the number of cells.
• Copy the new Calculated Table from Autotune into
  the F29x table of your Chip
• Save Chip with a new descriptive file name.
• View new Graph of F29x. Hand adjust cells that
  dont look right. WAY HIGH or WAY LOW. Need to
  look at surround cells and even them out. You
  dont want a lot of peaks and valleys.
