Hi there

I have got a TTO connected to cylinder 1. According to the manual when the limiter kicks in it starts by cutting the ignition to cylinder 1 so I thought I would got a more accurate reading moving to cylinder 2 or 3 however something strange is happening.

When I move the coil with the TTO wire attached to cylinders 2 or 3 it under reads by about 400rpm on tickover (800rpm), the dash says 1300ish rpm.
Move it back to cylinder 1 and its back up to 1300rpm.

The ski ticks over smooth and WOT is 63mph however its never been the best starter but I suspect that could the battery.

Any idea's ? could it be signal interference, anybody experience a similar problem?
