LB7 injector balance rates

[minytrker]

I finally ran the injector balance test with efi, here are my averages after idling for awhile at temperture. How do they look? (2003 LB7 stock tune)

1. -1.65mm³
2. -3.49mm³
3. -.30mm³
4. -1.17mm³
5. .29mm³
6. 2.71mm³
7. 2.84mm³
8. .97mm³

Lorenz, you need to specify units.

1. Start and run the engine until the engine coolant temperature is more than 82°C (180°F).
2. Turn OFF all accessories.
3. Hold the brake pedal in the fully applied position. A hiss will be noticeable when the brake is fully applied.
4. Place the transmission in Drive.
5. Idle the engine for more than 30 seconds.
6. Record the Balancing Rate Cyl.1-8 parameters from the scan tool while the engine is at idle speed.
7. Repeat steps 2-6 with the transmission in Neutral.

-6 mm³ and +6 mm³ is OK in gear, and -4 mm³ and +4 mm³ is OK in neutral.

Thanks I added them, it was mm³. I did that in park. I will re-do it Wed and follow your instructions and post my results. Thanks for the help.

I'm brand new to EFI live. How do you set up to do the balance rates. I've looked at the tutorials and haven't found any instructions. Can you help or point me in the right direction? Thanx

Also you need to log your fuel rate when checking them to get accurate numbers. If you have multiple injectors going out, it will lower your fuel rate at idle and keep the balance rates looking good.
