Cranking speed

Post by pommie02 »

in megatune it asks for your cranking speed.
do you set it to below your actual speed or over ?
i ask this because is this the point when the ecu switches from cranking to running ?

The significance of cranking speed is that above it the processor stops trigger rise mode for ignition and stops sending simultaneous, fixed width crank pulses for the injectors.

pommie02,

Just to add a bit to what Al says, you want to set the cranking speed *above* your actual cranking speed because you want the cranking settings in effect always while cranking. There's more here: http://www.megamanual.com/mt28.htm#so
