write an Arduino sketch

I am looking to build a compression tester for mazda wankel rotary engine. This will involve a 0-10 BAR pressure sensor outputting 0.5-5Volts. This signal is to be fed into an arduino uno with keypad LCD shield. The rotary engine has 3 seperate compression cycles (1 per rotation). RPM will need to be determined by counting the time between peak pressure values. The average peak value will then be required for each of the 3 rotor faces. This output will need to be "normalised" to 250RPM as per a predetermined graph table.
