Top of the day to you all,

Does anyone here use the autoenginuity.com scan tool and/speed tracer?

I a trying to find the specs for the speed tracer application.

I am looking for:

Gear Ratio
Working Gear X:1
Rear End Ratio X:1

Take a look at the photo below. I have a 05 Sedan 6MT. I have found some info and need to find the three items above. I would apreciate any help URL,DOC or digits. thanks in advance.

 

Gear Ratio is the total gear reduction value that you will be
using in the performance analysis. In the Dyno performance analysis,
the longer the sampling period, the more accurate the results
will be. Selecting too low of a gear will make it difficult to get an
accurate measurement; too high will require the vehicle to travel at
extremely high speeds. Typically, dynamometer testing is done in
third gear. The operating speeds of the vehicle in this gear are reasonable,
and the gearing allows for a long enough operating duration
to be accurate.

Is the statmnt about testing in thrid acurate?

Ifound that gear ratio. in the service manual.

 

1.624 for third
3.538 for the LSD Rear


these are from the SM... can anyone confirm I am using the proper specs?

 

I think I might have everything but the frontal area numbers:

As stated below-

Frontal Area
Frontal area represents the forward facing projection area of
the vehicle. This is used to compute the drag forces acting on the
vehicle during the performance analysis. Frontal area is the width
and height of the vehicle in square feet. The best source for this
information is the manufacturer’s specifications. Use the following
to compute frontal area:
1. Measure the distance in feet from one side of the vehicle to
the other. Do not include the mirrors in the measurement.
2. Multiply the measured width by the height of the lowest
leading edge of the vehicle’s front facia. Do not include the
tires, or start from the ground. We won’t be operating at
speeds where this will be factored in.
