What’s Code59?What’s 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

Why use Code59?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 won’t.

• 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.

What do I need?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)

• Ostrich, or chip burner– Huh? Ostrich WTF is that?

Moates Ostrich – Allows you to make tuning changes “on the fly” while the vehicle is runninghttp://www.moates.net/product_info.php?cPath=31&products_id=169

• Burner– Unlike the Ostrich, this won’t 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.http://www.moates.net/product_info.php?cPath=31&products_id=197

• Laptop - with USB• MS Office or OpenOffice to run AutoTune.


• Code59 XDF for TunerPro bin editing

• Code59 ADS for TunerPro logging

• Code59 Bin file for your Injector Size

• All of these can be found at www.code59.org

Getting StartedGetting Started

• I’ve got all of the above…now 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 <location>

– 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

How to hook up OstrichHow to hook up Ostrich to your ECM to your ECM

What COM port is my What COM port is my ALDL Cable on?ALDL Cable on?

1. Before connecting your USB ALDL Cable, Right click on My Computer and go to Properties.

2. 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.

In this example it is COM4

What exactly is a Bin, What exactly is a Bin, ADS and XDF?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– Road Map to where info is on the chip, and how

to display numbers so us dumb humans can understand it.

• Make sure XDF and ADS are in the same location

Exploring the Code59 Exploring the Code59 XDFXDF

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

Common ConstantsCommon Constants

• Closed Loop Temperature Enable

• RPM Limit

• EGR Shut Off

Closed Loop vs Open Closed Loop vs Open LoopLoop

• 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.

How to put ECM in How to put ECM in OPEN LOOP?OPEN LOOP?

• Do a find in TunerPro (CTRL+F) for Closed and look for the item labeled Temperature for Closed Loop Enable (KCLTC)

• Set this to 151°C to Force

the ECM into

OPEN LOOP

RPM Limit/Fuel RPM Limit/Fuel CutoffCutoff• 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 off……………JEFF

Disable EGRDisable EGR

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

Common FlagsCommon Flags

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

Basic Fuel/Timing Basic Fuel/Timing TablesTables

• 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

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

F29x – Main Fuel F29x – Main Fuel TableTable• F29x – This is the main fuel table. This is the

table Autotune works with.• Can’t go over 99.69VE in a cell• Now you can fine tune

the boost cells.

F77x – Boost F77x – Boost MultiplerMultipler• 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

F1 – Main Timing F1 – Main Timing TableTable• 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

Ideal Fuel RatioIdeal Fuel Ratio

• What is the ideal ratio?

• Cruise 14.0-15 : 1• Boost 10.5-12.0 : 1• Deceleration 15-20:1

• 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.

Where to begin?Where to begin?Driveability before WOTDriveability 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

What is a good tune?What is a good tune?

• Smoother is better– Make sure you don’t 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

Examples Fuel MapsExamples Fuel Maps

Not too good – Lots of Peaks and Valleys

Better – Smoother Transition between cells

• 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 can’t see if a sensor is bad,

garbage in garbage out, or other issues. Only works off the F29x table.

*Before Starting you need to make sure the Excel Analysis Pack installed and turned on in the ADD-ONs

1. Copy F29x table from your BIN2. Paste Into the FROM TunerPro Section in

Autotune3. Make Sure AFR table in Autotune matches

F29_AFR in your Chip 4. Open Exported LOG into Excel5. Highlight All Cells in the LOG and copy6. Click on the Upper Cell of the NON_AE_PE

Tab and paste the LOG file

7. Wait for Autotune to Calculate – Will take some time depending on the number of cells.

8. Copy the new Calculated Table from Autotune into the F29x table of your Chip

9. Save Chip with a new descriptive file name.10.View new Graph of F29x. Hand adjust cells

that don’t look right. WAY HIGH or WAY LOW. Need to look at surround cells and even them out. You don’t want a lot of peaks and valleys.

TunerPro 5 PREVIEWTunerPro 5 PREVIEW

• New Bubble • Improved ALDL logging – Goal is to no longer

need a separate tool like Datamaster for analyzing

• Histograms – Very Powerful Feature, step closer to TunerPro having Autotune builtin.

• Create your own Dashboards• Improved Monitor Graphing – Graph as many

items on a monitor as you like. No Limit on the number of items you want to graph

• Ostrich 2.0 Address Tracing
