RemoteTach A Analog and Digital tachometer with speed & course

By MSTApps

Open iTunes to buy and download apps.

Description

RemoteTach displays engine RPM for the gear set and tire size you enter into the data fields. It also displays speed in MPH, Altitude, Lat and Lon. This is a great app if you don't have a tachometer or if you want to check the calibration of a tach. You can also type in different transmission and axle ratios to see what your RPM would be if you changed them. You can also change the tire diameter to see how that would effect your RPM at a given speed in a selected gear.

The default data is for a Mustang GT with a 5 speed standard transmission with 17" Wheels.

Please note because this app uses GPS data to function you must be going over 3 MPH for it to start calculating.

Calculating RPM from SPEED

------------------------------------------

The relationship between engine speed (rpm) and road speed (mph) is determined by the characteristics of the drivetrain, from the crankshaft to the tire diameter. To calculate RPM, you will need to know the gear ratio(s) and the final drive ratio, or the overall ratio, and the diameter of the tires connected to the speedometer (usually the driven tires).

The gear ratios can be found in your owner's manual, Google or R&T data panel. To find the tire diameter use a tape measure and measure across your tires
center point from tread to tread.
