What would cause my rpm activated switch to activate twice on the 1 2 shift ? I tried a different rpm chip with no change.thanks,Sam.

RMI,EMI, Radio magnetic interference, Electro magnetic interference shruggy(my definitions abrevations(SP?) may be wrong for that problem but bleeding signals into the device is the problem shruggy
Both are caused by ignition wires, pick up, coil feed and spark plug wires, leaking signals into the device work scope

Because you are dropping below the RPM chip when it changes gear - meaning your RPM is falling back and then coming back and triggering again - only thing I can think of other than electrical interference - do you have a time out on that switch so that it can't trigger for a period of time after triggering ??
