FMD5036 is a simple fuel mix annalist. This devices measures
voltage from lambda and defines stoichiometric proportion
fuel/air. Can display either lambda value or proportion fuel/air.
That way car carburetors can be tuned precisely, with the
aim of optimal fuel usage. In the moment FMD5036 is working
with Bosch lambda LSH-24, but it is not a problem to be programmed
for other types - either narrow band or wide-band.
This device has 6-digit display with height digit of 10mm, but only 3 are used.
Can transmit data via RS-232C interface - that way statistics and graphic of tune process can be achieved.
With dimensions of 48x48mm it is easy to be embed in automobile
interior.

In it's normal mode FMD5036 shows current proportion between air and fuel.
This proportion varies from 0 to 24 (0 can not be achieved). The perfect
proportion is 14.7 (lambda = 1). When pressing the button, the display will now show
lambda value, instead of fuel-air ratio.
This device can transmit measured values via RS-232. Suitable
software can organize that data values in a way, that statistics
of carburetor work and graphics can be made.
