Setting a Fuel Injector to a Cylinder

1. Note the serial number (SN) and the checksum number (CS) on the fuel injector tag.


SN: Serial number

CS: Checksum number

 

2. Using this website, you can purchase the matching calibration file.

3. Save the calibration file to your PC computer in the folder: C:\Program Files\BRP\BUDSCommon\InjectorCoefficients.

4. Start B.U.D.S. and click on the Read Data button.

 

5. Select Setting and ECM tabs.

 

6. In the Injector Coefficient box, click on the New button of the fuel injector you want to replace (MAG or PTO).


ECM TAB UNDER SETTING TAB

NOTE: Every time the New button is clicked, B.U.D.S. will automatically open the Injector Coefficients folder.

7. Select and open the fuel injector serial number file that matches the fuel injector installed on the engine.

 

8. Enter the checksum number noted earlier and select Validate.

 

NOTE: The file will be quickly read and loaded in B.U.D.S.

9. Click the OK button when the confirmation box appears.

 

10. Click on the Write Data button to save the changes to the ECM.

 

IMPORTANT: To ensure the proper file has been saved in the ECM, do the following:

11. Click on the Read Data button again in B.U.D.S.

 

12. Look in the Injector Coefficient area in the ECM Setting page.

 

 

13. Ensure the S/N in B.U.D.S. matches the SN of the fuel injector installed on the engine and the PTO/MAG numbers are not inverted.

14. If there is a mismatch, reload the proper configuration file. Write data and read it again to recheck.

 

NOTE.

Every time an ECM is read or when an .mpem file is opened, the fuel injector calibration files (example: 07303050822720 and 07304010921720.inj) are automatically stored on your PC computer under a folder that will be common to all versions of B.U.D.S.: C:\Program Files\BRP\BUDSCommon\ InjectorCoefficients.

If B.U.D.S. is uninstalled, the files won't be deleted. If you ever replace an ECM from which you were not able to read the data, you could load its latest .mpem file, look at the fuel injector serial numbers stored in the ECM and then read the matching calibration files from the common files without the need to download the file from BOSSWeb.

If installing a NEW fuel injector, use BUDS2 to configure it in the ECM. Refer to MATCHING THE E-TEC DIRECT INJECTOR TO A CYLINDER.

NOTE: The engine will be able to run with an improperly matched fuel injector. However, the engine may misfire, run rough at idle, have poor fuel economy or run lean.

Matching the E-TEC Direct Injector to a Cylinder

1. Note the serial number (SN) and the checksum number (CS) on the fuel injector tag.

 

SN: Serial number

CS: Checksum number

2. Using this website, you can purchase the matching E-TEC injector calibration file.

2.1 Save the calibration file on the computer.

3. Connect the vehicle to the BRP diagnostic software (BUDS2).

4. In BUDS2, go to:

– Settings page

– Injector Coefficient

5. In the Injector Coefficient box, click on the New button of the fuel injector to be replaced (MAG or PTO) and find the previously saved file.

6. Select and open the fuel injector serial number file that matches the fuel injector installed on the engine.

7. Enter the checksum number noted earlier and select Write.

NOTE: The file will be loaded in BUDS2

8. Click the OK button when the confirmation box appears.

9. Click on the Write button to save the changes to the ECM.

IMPORTANT: To ensure the proper file has been saved in the ECM, do the following:

10. Click on the Scan button.

11. Look in the Injector Coefficient area in the Settings page.

12. Ensure the S/N matches the SN of the fuel injector installed on the engine and the PTO/MAG numbers are not inverted.

13. If there is a mismatch, reload the proper configuration file. Write data and read it again to recheck.


Please submit your request here: https://diag-systems.com/injector_coefficient_file

Did you buy a new injector for your snowmobile Skidoo/Lynx, but the seller did not provide the coefficient file?

The engine will be able to run with an improperly matched fuel injector. However, the engine may misfire, run rough at idle, have poor fuel economy or run lean.

But, if you know the 14-digit Serial Number (SN) and the 5-digit Checksum (CS) number from the injector label, here you can purchase the matching E-TEC injector calibration file(s) for your injector(s).

IMPORTANT! If you place and pay for your order, indicating the wrong numbers (especially for the CS (Checksum number)), I will be forced to cancel your order and make a refund of your payment, minus PayPal fees for the transaction. Please be careful when placing your order. PCN number is not the same as the number CS. Do not place an order if the Checksum number is missing on the label!

The coefficient file for your injector (s) will be sent within 1-12 hours (after payment) to your email registered with PayPal.
