How many injector codes do you need for a C-15?

How to create an injector trim code spreadsheet?
He did alot of work with injector trim codes. Testing flow of each. I took his information and made a spreadsheet. We all know were are not supposed to run straight 5232, 6999, or the like…due to the fact that no two injectors were created equal. Even a new set from CAT will be off from one another. Hence the need for trim codes.
When do I need to copy injector trim files?
An injector trim file must be loaded into the ECM if an injector is replaced. The “Copy Configuration” utility on Cat ET copies the injector trim files between two engine control modules. If the “Copy Configuration” fails, load all of the injector trim files manually into the new ECM.
Where do I find the serial number for injector trim?
Record the injector serial number and the injector confirmation code for each injector. Click on Service Software Files in SIS Web. Then select “Injector Trim Files”. Enter the serial number for the injector in the search field. Download the injector trim file to the PC. Repeat this procedure for each injector, as required.

“Injector Trim” is displayed below a 268-2 or 630-2 Programmed Parameter Fault : Erratic, Intermittent, or Incorrect. The diagnostic code is displayed on Cat ET.
How to troubleshoot an engine injector trim file?
Refer to Troubleshooting, “Electronic Service Tools”, if necessary. Select the appropriate cylinder. Click on the “Change” button. Select the appropriate injector trim file from the PC or the CD-ROM. Click on the “Open” button. Enter the injector confirmation code. Click on the “OK” button.The injector trim file is loaded into the ECM.
Where does the trim code go on a caterpillar?
Trim codes or trim files are codes that go into an Electronic Control Module (ECM) that determine how long a fuel injector injects fuel into a cylinder for. Trim codes only apply to electronic Caterpillar injectors and some newer electronic Cummins injectors.
How to test the injector solenoid on a C13 engine?
F. Perform the Injector Solenoid Test at least two times. Result: All cylinders indicate a -5 code on Cat ET. The harness between the ECM and the connector does not have a short circuit.Proceed to Test Step 5. Result: One or more cylinders indicate a -6 code on Cat ET.
What is the diagnostic code for Cat C13 engines?
3 Flash Code N/A Code 1387-15 1387-16 1387-00 0441-15 0441-16 0441-00 626-05 626-06 1835-03 1835-04 1836-03 1836-04 111-02 174-03 174-04 678-03 678-04 620-03 620-04 1079-04 100-03 100-04 100-10 102-03 102-04 102-10 108-03 108-04 110-03 110-04 91-13 91-08 Cross Reference for Diagnostic Codes Diagnostic Code Description of Code Event Code
What are the codes for the injector terminals?
These codes relate to the electrical circuit that includes injector terminals 2 and 4. These engines have Electronic Unit Injectors (EUI) that are electronically controlled. Each injector contains two solenoids. The Engine Control Module (ECM) sends 105 v pulses to each injector solenoid.
Do you need a trim file for an injector?
There’s your problem. You need the all full injector number to get the correct trim file for the injector.
What’s the best trim code for a C-15?
If you play with trim codes, I have got over 50 hp wheel difference of the dyno. The best is to have your injectors flow tested and then have the trims matched to the max ecm value of the injectors installed, you will have a smooth idling and pulling engine with 40 to 50 hp ore than stock.
How to check for the correct injector trim code?
Applying Injector Trim Codes using Scan Tool – Place the cursor in the correct trim code field – Clear the previous code – Scan the injector barcode – Check that the correct injector trim code has been updated.
How does the trim code affect the dyno?
Trim codes are result of injector calibration, All injectors flow different cc rates. The trim does affect idle but also across the whole fuel map. If you play with trim codes, I have got over 50 hp wheel difference of the dyno.
Where do I find the trim code for my injector?
Some injectors will come with a disc containing the unique trim code file. The disc will go into a computer and the computer will get connected to the ECM. Some programming will run and the injectors serial numbers will be inputted, which tells the ECM all of the injection data. If an injector needs a trim code, it should come with one.
How does et load injector trim into ECM?
The Caterpillar Electronic Technician (ET) is used to load injector trim files into the Engine Control Module (ECM). Injector trim files are available from these sources: A CD-ROM that is packaged with each new injector and each remanufactured injector

What kind of engine does a Caterpillar C15 have?
Caterpillar C15 six-cylinder diesel engines are used to power heavy equipment, industrial vehicles and commercial boats. The C15 employs an engine control module, or ECM, that interfaces with sensors on the fuel injectors. Signals from the ECM ignite heat plugs at the peak of each combustion stroke.
How to set the timing on a Caterpillar C15 engine?
Signals from the ECM ignite heat plugs at the peak of each combustion stroke. Typically, you set the injection timing as part of an extended maintenance program or when performing engine work. The job requires a Caterpillar Electronic Service Tool, or Cat-ET, and software disc specific to ACERT or earlier C15 engines.
How to access the injector trim calibration service?
To access this service, select the “Service” menu. Then select “Calibrations”. Select “Injector Trim Calibration”. Select two injectors and click the “Exchange” button. [/FONT] [FONT=”]”Copy Configuration” [/FONT] [FONT=”] – This service is used during replacement of an ECM. All of the injector trim files are copied from the ECM.
Do you know the trim code for ACERT?
Cat will swear the trim codes are for idle quality. Personally I’ve never had them make a difference in idle, but certain codes will give a little more power on non-Acert applications. Not sure for Acert though.
What does the IVA do on a C15?
The IVA does not have enough power to overcome the initial seat pressure of the valve springs. It does however have enough staying power to hold the valve open during the start of the compression stroke letting some of the intake charge to flow back into the intake and “pre heat” it for better combustion.
Where does the trim code go on a caterpillar fuel injector?
