The ALFA-Elite - TSD Rally Computer

ALFA-Elite Driver's DisplayALFA-Elite Rally Computer
Temporarily out of production while we retool a new version. Watch this site for detailed info coming soon!
The ALFA-Elite sets the standard for rally computers, with more features
for less money. Our customers prove it regularly by winning rallies!

All ALFA-Elite computers feature the latest state-of-the-art OLED back lit
display which is easily read in all lighting conditions and viewing angles.

A non-volatile memory remembers your factors, mileage's, log entry,
and customized setup even when the ALFA is removed from the car for
extended periods.

The ALFA-Elite has dual odometer sensor inputs, with individual factors,
to insure safety. Also, the computer will operate either with or without
its drivers display attached.

The ALFA-Elite operates in Miles or Kilometers, and displays distance in
increments of .01 or .001. Time may be displayed and computed in your
choice of seconds, hundredths, or thousandths of a minute.

One of the cool new features of the latest Elite is the driver's display which may be
disconnected from the computer at any time while both continue to run.
The main unit will continue to rally, while the driver's display becomes
a checkpoint clock with memories. While separated, the driver's display
may be synchronized with the main time clock for the rally, and then
when reconnected to the main unit that will synchronize as well. This
is an industry first and gives you 2 tools for the price of one!

All connections via standard round DIN connectors
Organic LED displays for 100% readability any time
