3.1.1

Types of Dyno runs


The Dyno supports 2 types of runs, distance and fixed gear.

A Distance Run is speed, time, and power measured over a quarter-mile. These can be useful for
gauging general vehicle performance.

Fixed Gear runs are generally made in one gear over a user specified RPM range (OT-2
hardware required). This is generally more useful for performance tuning, particular with the
addition of wideband (lambda/AFR) measurements from an MTS compatible device (like the
Innovate Motorsports LC-1).

Dyno supports up to two AFR channels as part of run data. If you need more than two

channels of AFR it is recommended that you record runs with the LogWorks tab and analyze the
results using our free LogWorks desktop software.

3.1.2

Accuracy


With OT-2 hardware, measurements of time, speed, RPM, and distance should have good
accuracy. With proper orientation, acceleration measurements taken from the iPhone/iPod touch
should also be good to fair.

However, with or without OT-2 hardware, power readings should not be taken as ‘absolute’
measurements but as ‘relative’ measurements for tuning and performance purposes. This is
because of the number of variables involved. Although the software attempts to correct for many
of them, like the shift in vehicle pitch normally experienced in acceleration, other factors, like the
drag coefficient of a particular vehicle and current atmospheric conditions, are not.

3.2 Economy Tab

The Economy tab will allow you to track your driving habits and see them real-time. By swiping
the screen to the left you will also find a very hand fuel log giving statistics on your GPM (Gallons
per Mile), CPM (Cost per Mile), and CPG (Cost per Gallon).

3.2.1

Measuring Fuel Economy


Select the real-time screen. Monitoring will start automatically.

The exact meaning of ‘Fuel Economy’ will depend upon the data
available from your vehicle’s ECU (OT-2 only). In all cases, a
higher number means better fuel economy and a lower number
means poorer economy.

‘Acceleration analysis’ can be thought of as a ‘smoothness’
score. Again, higher numbers are better than lower numbers. For
best accuracy, the iPhone/iPod touch should be kept stationary
and isolated from vibrating surfaces.
