Marelli Dash question

[yeti]

Anybody got any idea what the standard setting is for the KRPM constant on a Marelli MT940 race dash?

Seem to have lost the setting and as a) the rev counter doesn't start until 4k rpm and b) I don't have any means of measuring the rpm, it's gonna be a guess which of the 12 settings is correct.

A long shot I know..........

Jon, just read through the Marelli manual and no mention of a KRPM constant. What are the choices? The RPM signal is created from the crank sensor, so you get two pulses per ignition pulse. Don't know it that helps any.

Doesn't give me the value of the constant, but it's still a useful manual, thanks DC.

Gobsmacked nobody on here knows the answer to this one! Is this a first? An unanswered question?

Sorted, solved it myself. The answer was "2"
