This is where it gets wierd, plugs out, bike turns over GuzziDiag sees around 250-300 RPM and I get sparks. Plugs in no RPM signal at all plugs fire for a second then stop (I've got 2 lots of plugs). It sounds a healthy cranking speed to me, I've seen a lot slower starters labouring and starting an engine.
I'll try it again tomorrow, I'm with Wayne and Chuck, I need to clean the sensor plug up more, pull the sensor (and clean it if required) then check the phase sensor gap. Thinking that once it gets going the signal is strong enough to work, the voltage willl remain the same though and just the frequency would change. However if the signal is weak and it misses a few pulses at a higher RPM the ECU might not catch it or ignore it.
I wonder if the signal will fluctuate due to the gap, guess I'll find out? I plan to measure the DC volts on the signal wires too as I want to know what the input voltage is on the pickup, it could be a lot less than 12. Being me of course it will turn into science for Dummys 101, the wiring diagram shows 2 wires to that pickup and the plug has 3, which is what I expected, a pos, a neg and a signal. If I know the pos voltage I can emulate the input and when my Silly scope arrives I can look at the signal. I hope in the name of (insert your own diety here) that I've solved it by then though.
Nope all of that was fine and the sensor gap was massively wrong.I don't think Luigi built this one, perhaps Luigi Jnr on his first day as an apprentance they gave him a Hi Cam to buildThanks again all, once (if?) I get her to fire and get a pressure reading I'll post back up
