Tacho Pulses

[Lennart]

I got the tach working in the cluster, but the aftermarket tach is not moving. Should I try the pullup as well?

If the Tach in the gauge cluster (IPC) is functional and accurate, then the parameters in your tune are appropriate. Some aftermarket Tachs will require a pull up circuit - give it a try - can't do any harm if wired correctly.
