QUARTER MILE TEST

Select the Quarter Mile menu

item and Figure 10 will appear.

After bringing the vehicle to a

stop, follow the directions noted

on the screen. The Quarter mile

test will prompt you with a drag

strip style light tree. If you

watch the circles on the left they

will light up yellow, then green.

If you go before green appears

then a red light will light up in

the bottom showing that you

started too early. If you don’t

start early then you will see a

green light remain in the bottom

circle.

When you’ve ﬁ nished the

quarter mile run the device will

display the ending mph, the

distance traveled in ft., and the

elapsed time it took to reach 1/4

mile. In addition it will graph

your MPH vs Speed so you can

better analyze the run.

RECORDS

Records contain certain param-

eters for later review. This is

useful on the drag strip, at a sled

pull, or when you are trying to

trouble shoot a problem/bug.

INJECTOR BALANCE RATES

Injector Balance Rates are used

to determine if all the injectors

are operating within the correct

tolerances.

NOTE: Only available on cer-

tain models.

If you experience a misﬁ re,

knock, excessive smoke, or

rough running condition with

no DTCs, the Injector Balance

Rate option can help identify

faulty injectors.

The balance rates are the fuel

adjustments for each individual

cylinder based on the variations

in engine crankshaft speed. The

balance rates will change de-

pending on if the transmission

is in Neutral or Drive. Monitor

and record all cylinder balance

rates in drive and neutral. Injec-

tors that read a higher numerical

value than +/- 4.0 ( e.g. +/- 5,6,7

etc.) in park/neutral and +/-6.0

in drive may identify faulty

injectors.

If the balance rates show a pos-

sible faulty injector, we recom-

mend you consult a professional

diesel mechanic who can verify

this test and also perform a

Cylinder Power Balance test to

diagnose faulty injectors.

RUNNING THE TEST

1. Select Injector Bal-

ance Rates from the Di-

agnostics screen. You’ll

be prompted by the fol-

lowing screen. (Figure 11)
