Something I've been wanting to try for a while since reading Puckpuck's fitting of a microswitch. This takes that concept a bit further and uses an inductive proximity switch to sense when the secondaries are open. No moving parts, fully sealed, the device should perform without trouble. they are used in industrial machines etc to sense position of things, in fact similar to crankshaft position sensors etc. Anyway, this will allow me to monitor what the secondaries opening closing permanently from the driver's seat. Here are some pics of it fitted to my test lower manifold Secondaries closed  Secondaries open  I am going to mount the LED in the rev counter, below the centre of the needle  Keeps the brain active!!

That's cool! How much is that "industrial sensor" ? I have one in the works that has not moving parts either. I'm testing it now to see if it can withstand the engine temps.

love the idea...you could also rig something that woud allow you to override that opening so you could control when they opened...much like a manual choak on a lawnmower or go-cart engine.

There is acutally an easier way to do that, instead of having to yank off the upper manifolds tap a hole and all that. If you unscrew the IMRC box, the motor is exposed, then all you have to do is attach to wires to motor and connect that to a light.
When ever the motor open it will come on and the light will stay on until the motor is denergized. The ECU sends 12V to open the motor, then once it detects thats its open it lowers the voltage to hold them open. Even with the lower voltage a LED should stay on, or you can use a small incandecent bulb.
