What are good injector balance rates?
What are good injector balance rates?
When viewing the rates, a cylinder with (+) means that its injector is using more fuel than the average fuel rate and a (-) translates to less fuel. GM states that balance rates should be no more than plus or minus 4 (+4/-4) in park at operating temperature.
What is calculated fuel rate?
Fuel rate – average amount of fuel delivered to each cylinder measured in mm3/sec. It is an average. To calculate this value, the fuel rate for each cylinder is added together and then divided by 8 to obtain the fuel rate.
How do you calculate fuel percentage?
To figure the fuel surcharge percentage, you must calculate the average cost per gallon. Add up the total fuel costs for the trip and divide that by the total gallons bought. For example, if you pay $3,890 for 1,000 gallons of diesel, you get an average per gallon cost of $3.89.
How is FSC calculated?
Fuel Surcharge Formula Calculation To use the formula to calculate your fuel surcharge, subtract your fuel threshold amount from the actual price per gallon and divide that amount by vehicle’s miles per gallon.
How to check fuel return rate in GMC Duramax?
Remove the banjo bolt (4) from the junction block (2). Crank the engine for 15 seconds while observing the fuel pressure relief valve on the junction block for fuel leakage. • If fuel is leaking from the fuel pressure relief valve, replace the fuel pressure relief valve.

What kind of truck has a 4.5L Duramax V-8?
The 4.5L Duramax V-8 LMK never reached production. As such, it was never implemented in any models or vehicles. However, it was slated to go into GM’s light duty (half ton) pickup trucks – the Chevrolet Silverado 1500 and GMC Sierra 1500.

What is the balance rate on a Duramax?
Starting on 2006 all Duramax injectors use an injection quantity adjustment number on top. This is established by Bosch during testing. This number is stored in the ECM and the ECM uses it to further fine tune fuel delivery. Most trucks 06 and newer, the balance rates will be +/- 1mm3 or less.
What causes a negative fuel trim number on a Duramax?
Think of it like fuel trim, just on a cylinder by cylinder basis. If a injector is leaking, too much fuel gets into the cylinder. This will cause the piston to speed up faster than the other cylinders. The ECM monitors the crankshaft revolutions. When it sees the unusual increase in speed, it reduces fuel and a negative fuel trim number appears.
