40 000 rpm 
that will cover me

Very interesting Trevor. Does moving the magnet give you a different curve or just move when it starts and stops?
With the 2Ki and a computer the curve can be made like a set of steps or a rollercoaster.
Cheers
The closer the magnet to the pick up the steeper the curve.
Mike had to do a fair bit of fiddleing to get things working properly.
AFAIK the advance "curve" is a fairly straight line.
Mike blew up one tacho so he bought a very expensive digital strobe with inbuilt tacho.
That is how we found out about the cluster spark as we could not get a proper reading below 1800 rpm because the expensive unit picked up each spike in the cluster where as the cheapie was not sensative enough and saw the cluster as a single spark down to around 800 - 1000 rpm, when it went to toast.
Remember the unit was designed for model aircraft so initialy had 3 setting, idle , wfo & cruise.
The bloke who designed it is not interested in any developement for any use other than in models so is not very informative and JE are not much better, they just want to flog them.
If you were at Walllerawang, the blue Mettise/ Triumph that only stayed till the run around Bathurst was Mike, He had a problem back at the factory so had to go back.
The history is he got the frame, then a motor, then had the motor tweaked but it kept blowing the power transister out of the side on the Boyers.
Boyer sold him a special metal cased race unit along with a matched dual fire coil which also blew out.
So he stumbled upon these units before JE was doing them you had to get them from the UK @ £ 450 and then the "special" pick up units from some one else in the USA @ another $ 200.
He fitted them then as a 2nd year novice cleaned up every thing he went in till he stripped the main shaft.
Replace the entire box with a Quaife ( I think ) 3 speed drag box that was supposed to be extra strong and with that fitted cleaned up his 3rd season.
Then he let his vanquished in on the secret & fitted them to about 20ish bikes.
I was not doing much so ended up spending a lot of time assisting.
He regeared the bike to have a shot at Histeric Road racing but ended up burning big holes in both pistons.
In this trim he took the bike on a road trip & burned another hole so out for a dyno run to find the engine that was running little rich with the Boyers was running a lot lean with the Runtronics and quite a bit hotter to boot which is how we came up with upping the mains 2 sizes.
I was his sholder to lean on & ear to whisper in as he & I had done a lot of work putting a couple of B44's together previously when Pommie Iron was a mystery to him.
Should I ever get the round barrel B44 happening there is Runtronics with its number on it.
