Hello, Yes, the Megajolt calculates RPM based on the time interval between PIP signals. Thanks Brent. Rising edge, I assume, since the falling edge is variable? What exactly is the pattern of the PIP signal; I know that the falling edge is when an ignition event has taken place but when does PIP go...

Where does Megajolt get RPM information from?
Hi,
Since there is no connection for the crank sensor in Megajolt, is it safe to assume that the RPM information comes from the PIP signal? For a six cylinder engine, there would be three updates per revolution of the crank?
Thanks!

How does EDIS handle rapid RPM changes?
Hi, If I understand the EDIS system's operation correctly, it requires a SAW input after each PIP signal. The falling edge of the PIP signal is when a particular coil has just been fired and it's ready to receive information from Megajolt as to the ignition advance for the next event. If this is the...
